Authenticate connections to web_config service

- Require all requests to use a session path.
 - Use a redirect file to avoid exposing the URL on the command line, as
   it contains the session path.

Fix for CVE-2014-2914.
Closes #1438.

-# fish 2.3.1 (released July 3, 2016)
-
-This is a functionality and bugfix release. This release does not contain all the changes to fish since the last release, but fixes a number of issues directly affecting users at present and includes a small number of new features.
-
-## Significant changes
-- A new `fish_key_reader` binary for decoding interactive keypresses (#2991).
-- `fish_mode_prompt` has been updated to reflect the changes in the way the Vi input mode is set up (#3067), making this more reliable.
-- `fish_config` can now properly be launched from the OS X app bundle (#3140).
-
-## Notable fixes and improvements
-
-- Extra lines were sometimes inserted into the output under Windows (Cygwin and Microsoft Windows Subsystem for Linux) due to TTY timestamps not being updated (#2859).
-- The `string` builtin's `match` mode now handles the combination of `-rnv` (match, invert and count) correctly (#3098).
-- Improvements to TTY special character handling (#3064), locale handling (#3124) and terminal environment variable handling (#3060).
-- Work towards handling the terminal modes for external commands launched from initialisation files (#2980).
-- Ease the upgrade path from fish 2.2.0 and before by warning users to restart fish if the `string` builtin is not available (#3057).
-- `type -a` now syntax-colorizes function source output.
-- Added completions for `alsamixer`, `godoc`, `gofmt`, `goimports`, `gorename`, `lscpu`, `mkdir`, `modinfo`, `netctl-auto`, `poweroff`, `termite`, `udisksctl` and `xz` (#3123).
-- Improved completions for `apt` (#3097), `aura` (#3102),`git` (#3114), `npm` (#3158), `string` and `suspend` (#3154).
-
----
-
-# fish 2.3.0 (released May 20, 2016)
-
-There are no significant changes between 2.3.0 and 2.3b2.
-
-## Other notable fixes and improvements
-
-- `abbr` now allows non-letter keys (#2996).
-- Define a few extra colours on first start (#2987).
-- Multiple documentation updates.
-- Added completions for rmmod (#3007).
-- Improved completions for git (#2998).
-
-## Known issues
-
-- Interactive commands started from fish configuration files or from the `-c` option may, under certain circumstances, be started with incorrect terminal modes and fail to behave as expected. A fix is planned but requires further testing (#2619).
-
----
-
-# fish 2.3b2 (released May 5, 2016)
-
-## Significant changes
-
-- A new `fish_realpath` builtin and associated function to allow the use of `realpath` even on those platforms that don't ship an appropriate command (#2932).
-- Alt-# toggles the current command line between commented and uncommented states, making it easy to save a command in history without executing it.
-- The `fish_vi_mode` function is now deprecated in favour of `fish_vi_key_bindings`.
-
-## Other notable fixes and improvements
-
-- Fix the build on Cygwin (#2952) and RedHat Enterprise Linux/CentOS 5 (#2955).
-- Avoid confusing the terminal line driver with non-printing characters in `fish_title` (#2453).
-- Improved completions for busctl, git (#2585, #2879, #2984), and netctl.
-
----
-
-# fish 2.3b1 (released April 19, 2016)
-
-## Significant Changes
-
-- A new `string` builtin to handle... strings! This builtin will measure, split, search and replace text strings, including using regular expressions. It can also be used to turn lists into plain strings using `join`. `string` can be used in place of `sed`, `grep`, `tr`, `cut`, and `awk` in many situations. (#2296)
-- Allow using escape as the Meta modifier key, by waiting after seeing an escape character wait up to 300ms for an additional character. This is consistent with readline (e.g. bash) and can be configured via the `fish_escape_delay_ms variable`. This allows using escape as the Meta modifier. (#1356)
-- Add new directories for vendor functions and configuration snippets (#2500)
-- A new `fish_realpath` builtin and associated `realpath` function should allow scripts to resolve path names via `realpath` regardless of whether there is an external command of that name; albeit with some limitations. See the associated documentation.
-
-## Backward-incompatible changes
-
-- Unmatched globs will now cause an error, except when used with `for`, `set` or `count` (#2719)
-- `and` and `or` will now bind to the closest `if` or `while`, allowing compound conditions without `begin` and `end` (#1428)
-- `set -ql` now searches up to function scope for variables (#2502)
-- `status -f` will now behave the same when run as the main script or using `source` (#2643)
-- `source` no longer puts the file name in `$argv` if no arguments are given (#139)
-- History files are stored under the `XDG_DATA_HOME` hierarchy (by default, in `~/.local/share`), and existing history will be moved on first use (#744)
-
-## Other notable fixes and improvements
-
-- Fish no longer silences errors in config.fish (#2702)
-- Directory autosuggestions will now descend as far as possible if there is only one child directory (#2531)
-- Add support for bright colors (#1464)
-- Allow Ctrl-J (\cj) to be bound separately from Ctrl-M (\cm) (#217)
-- psub now has a "-s"/"–suffix" option to name the temporary file with that suffix
-- Enable 24-bit colors on select terminals (#2495)
-- Support for SVN status in the prompt (#2582)
-- Mercurial and SVN support have been added to the Classic + Git (now Classic + VCS) prompt (via the new \__fish_vcs_prompt function) (#2592)
-- export now handles variables with a "=" in the value (#2403)
-- New completions for:
-    -   alsactl
-    -   Archlinux's asp, makepkg
-    -   Atom's apm (#2390)
-    -   entr - the "Event Notify Test Runner" (#2265)

-    -   systemd's machinectl (#2158), busctl (#2144), systemd-nspawn, systemd-analyze, localectl, timedatectl
-    -   and more
-- Fish no longer has a function called sgrep, freeing it for user customization (#2245)
-- A rewrite of the completions for cd, fixing a few bugs (#2299, #2300, #562)
-- Linux VTs now run in a simplified mode to avoid issues (#2311)
-- The vi-bindings now inherit from the emacs bindings
-- Fish will also execute `fish_user_key_bindings` when in vi-mode
-- `funced` will now also check $VISUAL (#2268)
-- A new `suspend` function (#2269)
-- Subcommand completion now works better with split /usr (#2141)
-- The command-not-found-handler can now be overridden by defining a function called `__fish_command_not_found_handler` in config.fish (#2332)
-- A few fixes to the Sorin theme
-- PWD shortening in the prompt can now be configured via the `fish_prompt_pwd_dir_length` variable, set to the length per path component (#2473)
-- fish no longer requires `/etc/fish/config.fish` to correctly start, and now ships a skeleton file that only contains some documentation (#2799)

-# fish 2.2.0 (released July 12, 2015)
-
-### Significant changes ###
-
- * Abbreviations: the new `abbr` command allows for interactively-expanded abbreviations, allowing quick access to frequently-used commands (#731).
- * Vi mode: run `fish_vi_mode` to switch fish into the key bindings and prompt familiar to users of the Vi editor (#65).
- * New inline and interactive pager, which will be familiar to users of zsh (#291).
- * Underlying architectural changes: the `fishd` universal variable server has been removed as it was a source of many bugs and security problems. Notably, old fish sessions will not be able to communicate universal variable changes with new fish sessions. For best results, restart all running instances of `fish`.
- * The web-based configuration tool has been redesigned, featuring a prompt theme chooser and other improvements.
- * New German, Brazilian Portuguese, and Chinese translations.
-
-### Backward-incompatible changes ###
-
-These are kept to a minimum, but either change undocumented features or are too hard to use in their existing forms. These changes may break existing scripts.
-
- * `commandline` no longer interprets functions "in reverse", instead behaving as expected (#1567).
- * The previously-undocumented `CMD_DURATION` variable is now set for all commands and contains the execution time of the last command in milliseconds (#1585). It is no longer exported to other commands (#1896).
- * `if` / `else` conditional statements now return values consistent with the Single Unix Specification, like other shells (#1443).
- * A new "top-level" local scope has been added, allowing local variables declared on the commandline to be visible to subsequent commands. (#1908)
-
-### Other notable fixes and improvements ###
-
- * New documentation design (#1662), which requires a Doxygen version 1.8.7 or newer to build.
- * Fish now defines a default directory for other packages to provide completions. By default this is `/usr/share/fish/vendor-completions.d`; on systems with `pkgconfig` installed this path is discoverable with `pkg-config --variable completionsdir fish`.
- * A new parser removes many bugs; all existing syntax should keep working.
- * New `fish_preexec` and `fish_postexec` events are fired before and after job execution respectively (#1549).
- * Unmatched wildcards no longer prevent a job from running. Wildcards used interactively will still print an error, but the job will proceed and the wildcard will expand to zero arguments (#1482).
- * The `.` command is deprecated and the `source` command is preferred (#310).
- * `bind` supports "bind modes", which allows bindings to be set for a particular named mode, to support the implementation of Vi mode.
- * A new `export` alias, which behaves like other shells (#1833).
- * `command` has a new `--search` option to print the name of the disk file that would be executed, like other shells' `command -v` (#1540).
- * `commandline` has a new `--paging-mode` option to support the new pager.
- * `complete` has a new `--wraps` option, which allows a command to (recursively) inherit the completions of a wrapped command (#393), and `complete -e` now correctly erases completions (#380).
- * Completions are now generated from manual pages by default on the first run of fish (#997).
- * `fish_indent` can now produce colorized (`--ansi`) and HTML (`--html`) output (#1827).
- * `functions --erase` now prevents autoloaded functions from being reloaded in the current session.
- * `history` has a new `--merge` option, to incorporate history from other sessions into the current session (#825).
- * `jobs` returns 1 if there are no active jobs (#1484).
- * `read` has several new options:
-  * `--array` to break input into an array (#1540)
-  * `--null` to break lines on NUL characters rather than newlines (#1694)
-  * `--nchars` to read a specific number of characters (#1616)
-  * `--right-prompt` to display a right-hand-side prompt during interactive read (#1698).
- * `type` has a new `-q` option to suppress output (#1540 and, like other shells, `type -a` now prints all matches for a command (#261).
- * Pressing F1 now shows the manual page for the current command (#1063).
- * `fish_title` functions have access to the arguments of the currently running argument as `$argv[1]` (#1542).
- * The OS command-not-found handler is used on Arch Linux (#1925), nixOS (#1852), openSUSE and Fedora (#1280).
- * `Alt`+`.` searches backwards in the token history, mapping to the same behavior as inserting the last argument of the previous command, like other shells (#89).
- * The `SHLVL` environment variable is incremented correctly (#1634 & #1693).
- * Added completions for `adb` (#1165 & #1211), `apt` (#2018), `aura` (#1292), `composer` (#1607), `cygport` (#1841), `dropbox` (#1533), `elixir` (#1167), `fossil`, `heroku` (#1790), `iex` (#1167), `kitchen` (#2000), `nix` (#1167), `node`/`npm` (#1566), `opam` (#1615), `setfacl` (#1752), `tmuxinator` (#1863), and `yast2` (#1739).
- * Improved completions for `brew` (#1090 & #1810), `bundler` (#1779), `cd` (#1135), `emerge` (#1840),`git` (#1680, #1834 & #1951), `man` (#960), `modprobe` (#1124), `pacman` (#1292), `rpm` (#1236), `rsync` (#1872), `scp` (#1145), `ssh` (#1234), `sshfs` (#1268), `systemctl` (#1462, #1950 & #1972), `tmux` (#1853), `vagrant` (#1748), `yum` (#1269), and `zypper` (#1787).

-# fish 2.1.2  (released Feb 24, 2015)
-
-fish 2.1.2 contains a workaround for a filesystem bug in Mac OS X Yosemite. #1859
-
-Specifically, after installing fish 2.1.1 and then rebooting, "Verify Disk" in Disk Utility will report "Invalid number of hard links." We don't have any reports of data loss or other adverse consequences. fish 2.1.2 avoids triggering the bug, but does not repair an already affected filesystem. To repair the filesystem, you can boot into Recovery Mode and use Repair Disk from Disk Utility. Linux and versions of OS X prior to Yosemite are believed to be unaffected.
-
-There are no other changes in this release.
-
----
-
-# fish 2.1.1 (released September 26, 2014)
-
-__Important:__ if you are upgrading, stop all running instances of `fishd` as soon as possible after installing this release; it will be restarted automatically. On most systems, there will be no further action required. Note that some environments (where `XDG_RUNTIME_DIR` is set), such as Fedora 20, will require a restart of all running fish processes before universal variables work as intended.
-
-Distributors are highly encouraged to call `killall fishd`, `pkill fishd` or similar in installation scripts, or to warn their users to do so.
-
-### Security fixes
- * The fish_config web interface now uses an authentication token to protect requests and only responds to requests from the local machine with this token, preventing a remote code execution attack. (closing CVE-2014-2914). #1438
- * `psub` and `funced` are no longer vulnerable to attacks which allow local privilege escalation and data tampering (closing CVE-2014-2906 and CVE-2014-3856). #1437
- * `fishd` uses a secure path for its socket, preventing a local privilege escalation attack (closing CVE-2014-2905). #1436
- * `__fish_print_packages` is no longer vulnerable to attacks which would allow local privilege escalation and data tampering (closing CVE-2014-3219). #1440
-
-### Other fixes
- * `fishd` now ignores SIGPIPE, fixing crashes using tools like GNU Parallel and which occurred more often as a result of the other `fishd` changes. #1084 & #1690
-
----
-
-# fish 2.1.0
-
-Significant Changes
--------------------
-
-* **Tab completions will fuzzy-match files.** #568
-
-  When tab-completing a file, fish will first attempt prefix matches (`foo` matches `foobar`), then substring matches (`ooba` matches `foobar`), and lastly subsequence matches (`fbr` matches `foobar`). For example, in a directory with files foo1.txt, foo2.txt, foo3.txt…, you can type only the numeric part and hit tab to fill in the rest.
-
-  This feature is implemented for files and executables. It is not yet implemented for options (like `--foobar`), and not yet implemented across path components (like `/u/l/b` to match `/usr/local/bin`).
-
-* **Redirections now work better across pipelines.** #110, #877
-
-  In particular, you can pipe stderr and stdout together, for example, with `cmd ^&1 | tee log.txt`, or the more familiar `cmd 2>&1 | tee log.txt`.
-
-* **A single `%` now expands to the last job backgrounded.** #1008
-
-  Previously, a single `%` would pid-expand to either all backgrounded jobs, or all jobs owned by your user. Now it expands to the last job backgrounded. If no job is in the background, it will fail to expand. In particular, `fg %` can be used to put the most recent background job in the foreground.
-
-Other Notable Fixes
--------------------
-
-* alt-U and alt+C now uppercase and capitalize words, respectively. #995
-
-* VTE based terminals should now know the working directory. #906
-
-* The autotools build now works on Mavericks. #968
-
-* The end-of-line binding (ctrl+E) now accepts autosuggestions. #932
-
-* Directories in `/etc/paths` (used on OS X) are now prepended instead of appended, similar to other shells. #927
-
-* Option-right-arrow (used for partial autosuggestion completion) now works on iTerm2. #920
-
-* Tab completions now work properly within nested subcommands. #913
-
-* `printf` supports \e, the escape character. #910
-
-* `fish_config history` no longer shows duplicate items. #900
-
-* `$fish_user_paths` is now prepended to $PATH instead of appended. #888
-
-* Jobs complete when all processes complete. #876
-
-
-  For example, in previous versions of fish, `sleep 10 | echo Done` returns control immediately, because echo does not read from stdin. Now it does not complete until sleep exits (presumably after 10 seconds).
-
-* Better error reporting for square brackets. #875
-
-* fish no longer tries to add `/bin` to `$PATH` unless PATH is totally empty. #852
-
-* History token substitution (alt-up) now works correctly inside subshells. #833
-
-* Flow control is now disabled, freeing up ctrl-S and ctrl-Q for other uses. #814
-
-* sh-style variable setting like `foo=bar` now produces better error messages. #809
-
-* Commands with wildcards no longer produce autosuggestions. #785
-
-* funced no longer freaks out when supplied with no arguments. #780
-
-* fish.app now works correctly in a directory containing spaces. #774
-
-* Tab completion cycling no longer occasionally fails to repaint. #765
-
-* Comments now work in eval'd strings. #684
-
-* History search (up-arrow) now shows the item matching the autosuggestion, if that autosuggestion was truncated. #650
-
-* Ctrl-T now transposes characters, as in other shells. #128

-Significant Changes
--------------------
-
-* **Command substitutions now modify `$status` #547.**
-  Previously the exit status of command substitutions (like `(pwd)`) was ignored; however now it modifies $status. Furthermore, the `set` command now only sets $status on failure; it is untouched on success. This allows for the following pattern:
-
-  ```sh
-  if set python_path (which python)
-     ...
-  end
-  ```
-  Because set does not modify $status on success, the if branch effectively tests whether `which` succeeded, and if so, whether the `set` also succeeded.
-* **Improvements to $PATH handling.**
-    * There is a new variable, `$fish_user_paths`, which can be set universally, and whose contents are appended to $PATH #527
-    * /etc/paths and /etc/paths.d are now respected on OS X
-    * fish no longer modifies $PATH to find its own binaries
-* **Long lines no longer use ellipsis for line breaks**, and copy and paste
-  should no longer include a newline even if the line was broken #300
-* **New syntax for index ranges** (sometimes known as "slices") #212
-* **fish now supports an `else if` statement** #134
-* **Process and pid completion now works on OS X** #129
-* **fish is now relocatable**, and no longer depends on compiled-in paths #125
-* **fish now supports a right prompt (RPROMPT)** through the fish_right_prompt function #80
-* **fish now uses posix_spawn instead of fork when possible**, which is much faster on BSD and OS X #11
-

-# fishfish Beta r2
-
-Bug Fixes
----------
-
-* **Implicit cd** is back, for paths that start with one or two dots, a slash, or a tilde.
-* **Overrides of default functions should be fixed.** The "internalized scripts" feature is disabled for now.
-* **Disabled delayed suspend.** This is a strange job-control feature of BSD systems, including OS X. Disabling it frees up Control Y for other purposes; in particular, for yank, which now works on OS X.
-* **fish_indent is fixed.** In particular, the `funced` and `funcsave` functions work again.
-* A SIGTERM now ends the whole execution stack again (resolving #13).
-* Bumped the __fish_config_interactive version number so the default fish_color_autosuggestion kicks in.
-* fish_config better handles combined term256 and classic colors like "555 yellow". 
-
-New Features
-------------
-
-* **A history builtin**, and associated interactive function that enables deleting history items. Example usage:
-      * Print all history items beginning with echo: `history --prefix echo`
-      * Print all history items containing foo: `history --contains foo`
-      * Interactively delete some items containing foo: `history --delete --contains foo`

-# fishfish Beta r1
-
-## Scripting
-* No changes! All existing fish scripts, config files, completions, etc. from trunk should continue to work.
-
-## New Features
-* **Autosuggestions**. Think URL fields in browsers. When you type a command, fish will suggest the rest of the command after the cursor, in a muted gray when possible. You can accept the suggestion with the right arrow key or Ctrl-F. Suggestions come from command history, completions, and some custom code for cd; there's a lot of potential for improvement here. The suggestions are computed on a background pthread, so they never slow down your typing. The autosuggestion feature is incredible. I miss it dearly every time I use anything else.
-
-* **term256 support** where available, specifically modern xterms and OS X Lion. You can specify colors the old way ('set_color cyan') or by specifying RGB hex values ('set_color FF3333'); fish will pick the closest supported color. Some xterms do not advertise term256 support either in the $TERM or terminfo max_colors field, but nevertheless support it. For that reason, fish will default into using it on any xterm (but it can be disabled with an environment variable).
-
-* **Web-based configuration** page. There is a new function 'fish_config'. This spins up a simple Python web server and opens a browser window to it. From this web page, you can set your shell colors and view your functions, variables, and history; all changes apply immediately to all running shells. Eventually all configuration ought to be supported via this mechanism (but in addition to, not instead of, command line mechanisms).
-
-* **Man page completions**. There is a new function 'fish_update_completions'. This function reads all the man1 files from your manpath, removes the roff formatting, parses them to find the commands and options, and outputs fish completions into ~/.config/fish/completions. It won't overwrite existing completion files (except ones that it generated itself).
-
-## Programmatic Changes
-* fish is now entirely in C++. I have no particular love for C++, but it provides a ready memory-model to replace halloc. We've made an effort to keep it to a sane and portable subset (no C++11, no boost, no going crazy with templates or smart pointers), but we do use the STL and a little tr1.
-* halloc is entirely gone, replaced by normal C++ ownership semantics. If you don't know what halloc is, well, now you have two reasons to be happy.
-* All the crufty C data structures are entirely gone. array_list_t, priority_queue_t, hash_table_t, string_buffer_t have been removed and replaced by STL equivalents like std::vector, std::map, and std::wstring. A lot of the string handling now uses std::wstring instead of wchar_t *
-* fish now spawns pthreads for tasks like syntax highlighting that require blocking I/O.
-* History has been completely rewritten. History files now use an extensible YAML-style syntax. History "merging" (multiple shells writing to the same history file) now works better. There is now a maximum history length of about 250k items (256 * 1024).
-* The parser has been "instanced," so you can now create more than one.
-* Total #LoC has shrunk slightly even with the new features.
-
-## Performance
-* fish now runs syntax highlighting in a background thread, so typing commands is always responsive even on slow filesystems.
-* echo, test, and pwd are now builtins, which eliminates many forks.
-* The files in share/functions and share/completions now get 'internalized' into C strings that get compiled in with fish. This substantially reduces the number of files touched at startup. A consequence is that you cannot change these functions without recompiling, but often other functions depend on these "standard" functions, so changing them is perhaps not a good idea anyways.
-
-Here are some system call counts for launching and then exiting fish with the default configuration, on OS X. The first column is fish trunk, the next column is with our changes, and the last column is bash for comparison. This data was collected via dtrace.
-
-<table>
-<tr> <th> <th> before <th> after <th> bash
-<tr> <th> open <td> 9 <td> 4 <td> 5
-<tr> <th> fork <td> 28 <td> 14 <td> 0
-<tr> <th> stat <td> 131 <td> 85 <td> 11
-<tr> <th> lstat <td> 670 <td> 0 <td> 0
-<tr> <th> read <td> 332 <td> 80 <td> 4
-<tr> <th> write <td> 172 <td> 149 <td> 0
-</table>
-
-The large number of forks relative to bash are due to fish's insanely expensive default prompt, which is unchanged in my version. If we switch to a prompt comparable to bash's (lame) default, the forks drop to 16 with trunk, 4 after our changes.
-
-The large reduction in lstat() numbers is due to fish no longer needing to call ttyname() on OS X.
-
-We've got some work to do to be as lean as bash, but we're on the right track.

-# Guidelines For Developers
-
-This document provides guidelines for making changes to the fish-shell project. This includes rules for how to format the code, naming conventions, etc. It also includes recommended best practices such as creating a Travis-CI account so you can verify your changes pass all the tests before making a pull-request.
-
-See the bottom of this document for help on installing the linting and style reformatting tools discussed in the following sections.
-
-## Lint Free Code
-
-Automated analysis tools like cppcheck and oclint can point out potential bugs. They also help ensure the code has a consistent style and that it avoids patterns that tend to confuse people.
-
-Ultimately we want lint free code. However, at the moment a lot of cleanup is required to reach that goal. For now simply try to avoid introducing new lint.
-
-To make linting the code easy there are two make targets: `lint` and `lint-all`. The latter does just what the name implies. The former will lint any modified but not committed `*.cpp` files. If there is no uncommitted work it will lint the files in the most recent commit.
-
-### Dealing With Lint Warnings
-
-You are strongly encouraged to address a lint warning by refactoring the code, changing variable names, or whatever action is implied by the warning.
-
-### Suppressing Lint Warnings
-
-Once in a while the lint tools emit a false positive warning. For example, cppcheck might suggest a memory leak is present when that is not the case. To suppress that cppcheck warning you should insert a line like the following immediately prior to the line cppcheck warned about:
-
-```
-// cppcheck-suppress memleak // addr not really leaked
-```
-
-The explanatory portion of the suppression comment is optional. For other types of warnings replace "memleak" with the value inside the parenthesis (e.g., "nullPointerRedundantCheck") from a warning like the following:
-
-```
-[src/complete.cpp:1727]: warning (nullPointerRedundantCheck): Either the condition 'cmd_node' is redundant or there is possible null pointer dereference: cmd_node.
-```
-
-Suppressing oclint warnings is more complicated to describe so I'll refer you to the [OCLint HowTo](http://docs.oclint.org/en/latest/howto/suppress.html#annotations) on the topic.
-
-## Ensuring Your Changes Conform to the Style Guides
-
-The following sections discuss the specific rules for the style that should be used when writing fish code. To ensure your changes conform to the style rules you simply need to run
-
-```
-make style
-```
-
-before commiting your change. If you've already committed your changes that's okay since it will then check the files in the most recent commit. This can be useful after you've merged someone elses change and want to check that it's style is acceptable.
-
-If you want to check the style of the entire code base run
-
-```
-make style-all
-```
-
-### Suppressing Reformatting of the Code
-
-If you have a good reason for doing so you can tell `clang-format` to not reformat a block of code by enclosing it in comments like this:
-
-```
-// clang-format off
-code to ignore
-// clang-format on
-```
-
-## Fish Script Style Guide
-
-Fish scripts such as those in the *share/functions* and *tests* directories should be formatted using the `fish_indent` command.
-
-Function names should be all lowercase with undescores separating words. Private functions should begin with an underscore. The first word should be `fish` if the function is unique to fish.
-
-The first word of global variable names should generally be `fish` for public vars or `_fish` for private vars to minimize the possibility of name clashes with user defined vars.
-
-## C++ Style Guide
-
-1. The [Google C++ Style Guide](https://google.github.io/styleguide/cppguide.html) forms the basis of the fish C++ style guide. There are two major deviations for the fish project. First, a four, rather than two, space indent. Second, line lengths up to 100, rather than 80, characters.
-
-1. The `clang-format` command is authoritative with respect to indentation, whitespace around operators, etc. **Note**: this rule should be ignored at this time. After the code is cleaned up this rule will become mandatory.
-
-1. All names in code should be `small_snake_case`. No Hungarian notation is used. Classes and structs names should be followed by `_t`.
-
-1. Always attach braces to the surrounding context.
-
-1. Indent with spaces, not tabs and use four spaces per indent.
-
-1. Comments should always use the C++ style; i.e., each line of the comment should begin with a `//` and should be limited to 100 characters. Comments that do not begin a line should be separated from the previous text by two spaces.
-
-## Testing
-
-The source code for fish includes a large collection of tests. If you are making any changes to fish, running these tests is highly recommended to make sure the behaviour remains consistent.
-
-You are also strongly encouraged to add tests when changing the functionality of fish. Especially if you are fixing a bug to help ensure there are no regressions in the future (i.e., we don't reintroduce the bug).
-
-### Local testing
-
-The tests can be run on your local computer on all operating systems.
-
-Running the tests is only supported from the autotools build and not xcodebuild. On OS X, you will need to install autoconf — we suggest using [Homebrew](http://brew.sh/) to install these tools.
-
-    autoconf
-    ./configure
-    make test [gmake on BSD]
-
-### Travis CI Build and Test
-
-The Travis Continuous Integration services can be used to test your changes using multiple configurations. This is the same service that the fish shell project uses to ensure new changes haven't broken anything. Thus it is a really good idea that you leverage Travis CI before making a pull-request to avoid embarrasment at breaking the build.
-
-You will need to [fork the fish-shell repository on GitHub](https://help.github.com/articles/fork-a-repo/). Then setup Travis to test your changes before you make a pull-request:
-
-1. [Sign in to Travis CI](https://travis-ci.org/auth) with your GitHub account, accepting the GitHub access permissions confirmation.
-1. Once you're signed in, and your repositories are synchronised, go to your [profile page](https://travis-ci.org/profile) and enable the fish-shell repository.
-1. Push your changes to GitHub.
-
-You'll receive an email when the tests are complete telling you whether or not any tests failed.
-
-You'll find the configuration used to control Travis in the `.travis.yml` file.
-
-## Installing the Required Tools
-
-### Installing the Linting Tools
-
-To install the lint checkers on Mac OS X using HomeBrew:
-
-```
-brew tap oclint/formulae
-brew install oclint
-brew install cppcheck
-```
-
-To install the lint checkers on Linux distros that use Apt:
-
-```
-sudo apt-get install clang
-sudo apt-get install oclint
-sudo apt-get install cppcheck
-```
-
-### Installing the Reformatting Tools
-
-To install the reformatting tool on Mac OS X using HomeBrew:
-
-```
-brew install clang-format
-```
-
-To install the reformatting tool on Linux distros that use Apt:
-
-```
-apt-cache search clang-format
-```
-
-That will list the versions available. Pick the newest one available (3.6 for Ubuntu 14.04 as I write this) and install it:
-
-```
-sudo apt-get install clang-format-3.6
-sudo ln -s /usr/bin/clang-format-3.6 /usr/bin/clang-format
-
-```

-Translation support requires the gettext program.
-
-Some optional features of fish, such as the manual page completion parser and the web configuration tool, require Python.
-
-In order to generate completions from man pages compressed with either lzma or xz, you may need to install an extra Python package. Python versions prior to 2.6 are not supported.  For Python versions 2.6 to 3.2 you need to install the module `backports.lzma`.  How to install it depends on your system and how you installed Python.  Most Linux distributions should include it as a package named `backports-lzma` (or similar).  From version 3.3 onwards, Python already includes the required module.

+# Style guide
+
+This is style guide for fish contributors. You should use it for any new code
+that you would add to this project and try to format existing code to use this
+style.
+
+## Formatting
+
+1. fish uses the Allman/BSD style of indentation.
+2. Indent with spaces, not tabs.
+3. Use 4 spaces per indent (unless needed like `Makefile`).
+4. Opening curly bracket is on the following line:
+
+        // ✔:
+        struct name
+        {
+          // code
+        };
+
+        void func()
+        {
+          // code
+        }
+
+        if (...)
+        {
+          // code
+        }
+
+        // ✗:
+        void func() {
+          // code
+        }
+
+5. Put space after `if`, `while` and `for` before conditions.
+
+        // ✔:
+        if () {}
+
+        // ✗:
+        if() {}
+
+6. Put spaces before and after operators excluding increment and decrement;
+
+        // ✔:
+        int a = 1 + 2 * 3;
+        a++;
+
+        // ✗:
+        int a=1+2*3;
+        a ++;
+
+7. Never put spaces between function name and parameters list.
+
+        // ✔:
+        func(args);
+
+        // ✗:
+        func (args);
+
+8. Never put spaces after `(` and before `)`.
+9. Always put space after comma and semicolon.
+
+        // ✔:
+        func(arg1, arg2);
+
+        for (int i = 0; i < LENGTH; i++) {}
+
+        // ✗:

-# Formatting guide for fish docs
-
-The fish documentation has been updated to support Doxygen 1.8.7+, and while the main benefit of this change is extensive Markdown support, the addition of a fish lexicon and syntax filter, combined with semantic markup rules allows for automatic formatting enhancements across the HTML user_docs, the developer docs and the man pages.
-
-Initially my motivation was to fix a problem with long options ([Issue #1557](https://github.com/fish-shell/fish-shell/issues/1557) on GitHub), but as I worked on fixing the issue I realised there was an opportunity to simplify, reinforce and clarify the current documentation, hopefully making further contribution easier and cleaner, while allowing the documentation examples to presented more clearly with less author effort.
-
-While the documentation is pretty robust to variations in the documentation source, adherence to the following style guide will help keep the already excellent documention in good shape moving forward.
-
-## Line breaks and wrapping
-
-Contrary to the rest of the fish source code, the documentation greatly benefits from the use of long lines and soft wrapping. It allows paragraphs to be treated as complete blocks by Doxygen, means that the semantic filter can see complete lines when deciding on how to apply syntax highlighting, and means that man pages will consistently wrap to the width of the users console in advanced pagers, such as 'most'. 
-
-## Doxygen special commands and aliases
-
-While Markdown syntax forms the basis of the documentation content, there are some exceptions that require the use of Doxygen special commands. On the whole, Doxygen commands should be avoided, especially inline word formatting such as \\c as this would allow Doxygen to make unhelpful assumptions, such as converting double dashes (\--) to n-dashes (–).
-
-### Structure: \\page, \\section and \\subsection
-
-Use of Doxygen sections markers are important, as these determine what will be eventually output as a web page, man page or included in the developer docs. 
-
-Currently the make process for the documentation is quite convoluted, but basically the HTML docs are produced from a single, compiled file, doc.h. This contains a number of \\page markers that produce the various pages used in the documentation. The format of a \\page mark is:
-
-    \page universally_unique_page_id Page title
-
-The source files that contain the page markers are currently:
-
-- __index.hdr.in__: Core documentation
-- __commands.hdr.in__: Individual commands
-- __tutorial.hdr__: Tutorial
-- __design.hdr__: Design document
-- __faq.hdr__: Frequently Asked Questions
-- __license.hdr__: Fish and 3rd party licences
-
-Unless there is a _VERY_ good reason and developer consensus, new pages should never be added.
-
-The rest of the documentation is structured using \\section and \\subsection markers. Most of the source files (listed above) contain their full content, the exception being commands, which are separated out into source text files in the doc_src directory. These files are concatenated into one file, so each one starts with a \\section declaration. The synopsis, description and examples (if present) are declared as \\subsections. The format of these marks is practically identical to the page mark.
-
-    \section universally_unique_section_id Section title
-    \subsection universally_unique_subsection_id Subsection title
-
-Each page, section and subsection id _must_ be unique across the whole of the documentation, otherwise Doxygen will issue a warning.
-
-### Semantic markup: the \\fish .. \\endfish block
-
-While Doxygen has support for \\code..\\endcode blocks with enhanced markup and syntax colouring, it only understands the core Doxygen languages: C, C++, Objective C, Java, PHP, Python, Tcl and Fortran. To enhance Fish's syntax presentation, use the special \\fish..\\endfish blocks instead.
-
-Text placed in this block will be parsed by Doxygen using the included lexicon filter (see lexicon_filter.in) as a Doxygen input filter. The filter is built during make so that it can pick up information on builtins, functions and shell commands mentioned in completions and apply markup to keywords found inside the \\fish block.
-
-Basically, preformatted plain text inside the \\fish block is fed through the filter and is returned marked up so that Doxygen aliases can convert it back to a presentable form, according to the output document type.
-
-For instance:
-
-`echo hello world`
-
-is transformed into:
-
-`@cmnd{echo} @args{hello} @args{world}`
-
-which is then transformed by Doxygen into an HTML version (`make doc`):
-
-`<span class="command">echo</span> <span class="argument">hello</span> <span class="argument">world</span>`
-
-A man page version (`make share/man`):
-
-__echo__ hello world
-
-And a simple HTML version for the developer docs (`make doc`) and the LATEX/PDF manual  (`make doc/refman.pdf`):
-
-`echo hello world`
-
-### Fonts
-
-In older browsers, it was easy to set the fonts used for the three basic type styles (serif, sans-serif and monospace). Modern browsers have removed these options in their respective quests for simplification, assuming the content author will provide suitable styles for the content in the site's CSS, or the end user will provide overriding styles manually. Doxygen's default styling is very simple and most users will just accept this default.
-
-I've tried to use a sensible set of fonts in the documentation's CSS based on 'good' terminal fonts and as a result the firt preference font used throughout the documentation is '[DejaVu](http://dejavu-fonts.org)'. The rationale behaind this is that while DejaVu is getting a little long in the tooth, it still provides the most complete support across serif, sans-serif and monospace styles (giving a well balanced feel and consistent [x-height](http://en.wikipedia.org/wiki/X-height)), has the widest support for extended Unicode characters and has a free, permissive licenses (though it's still incompatible with GPLv2, though arguably less so than the SIL Open Font license, though this is a moot point when using it solely in the docs).
-
-#### Fonts inside \\fish blocks and \`backticks\`
-
-As the point of these contructs is to make fish's syntax clearer to the user, it makes sense to mimic what the user will see in the console, therefore any content is formatted using the monospaced style, specifically monospaced fonts are chosen in the following order:
-
-1. __DejaVu Sans Mono__: Explained above. [[&darr;](http://dejavu-fonts.org)]
-2. __Source Code Pro__: Monospaced code font, part of Adobe's free Edge Web Fonts. [[&darr;](https://edgewebfonts.adobe.com)]
-3. __Menlo__: Apple supplied variant of DejaVu.
-4. __Ubuntu Mono__: Ubuntu Linux's default monospaced font. [[&darr;](http://font.ubuntu.com)]
-5. __Consolas__: Modern Microsoft supplied console font.
-6. __Monaco__: Apple supplied console font since 1984!
-7. __Lucida Console__: Generic mono terminal font, standard in many OS's and distros.
-8. __monospace__: Catchall style. Chooses default monospaced font, often Courier.
-9. __fixed__: As above, more often used on mobile devices.
-
-#### General Fonts
-
-1. __DejaVu Sans__: As above.[[&darr;](http://dejavu-fonts.org)]
-2. __Roboto__: Elegant Google free font and is Doxygen's default [[&darr;](http://www.google.com/fonts/specimen/Roboto)]
-3. __Lucida Grande__: Default Apple OS X content font.
-4. __Calibri__: Default Microsoft Office font (since 2007).
-5. __Verdana__: Good general font found in a lot of OSs.
-6. __Helvetica Neue__: Better spaced and balanced Helvetica/Arial variant.
-7. __Helvetica__: Standard humanist typeface found almost everywhere.
-8. __Arial__: Microsoft's Helvetica.
-9. __sans-serif__: Catchall style. Chooses default sans-serif typeface, often Helvetica.
-
-The ordering of the fonts is important as it's designed to allow the documentation to settle into a number of different identities according to the fonts available. If you have the complete DejaVu family installed, then the docs are presented using that, and if your Console is set up to use the same fonts, presentation will be completely consistent.
-
-On OS X, with nothing extra installed, the docs will default to Menlo and Lucida Grande giving a Mac feel. Under Windows, it will default to using Consolas and Calibri on recent versions, giving a modern Windows style.
-
-#### Other sources:
-
-- [Font Squirrel](http://www.fontsquirrel.com): Good source of open source font packages.
-
-### Choosing a CLI style: using a \\fish{style} block
-
-By default, when output as HTML, a \\fish block uses syntax colouring suited to the style of the documentation rather than trying to mimic the terminal. The block has a light, bordered background and a colour scheme that 'suggests' what the user would see in a console.
-
-Additional stying can be applied adding a style declaration:
-
-    \fish{additional_style [another_style...]}
-        ...
-    \endfish
-
-This will translate to classes applied to the `<div>` tag, like so:
-
-    <div class="fish additional_style another_style">
-        ...
-    </div>
-
-The various classes are defined in `doc_src/user_doc.css` and new style can be simply added
-
-The documentation currently defines a couple of additional styles:
-
-- __cli-dark__: Used in the _tutorial_ and _FAQ_ to simulate a dark background terminal, with fish's default colours (slightly tweaked for legibility in the browser).
-
-- __synopsis__: A simple colour theme helpful for displaying the logical 'summary' of a command's syntax, options and structure.
-
-## Markdown
-
-Apart from the exceptions discussed above, the rest of the documentation now supports the use of Markdown. As such the use of Doxygen special commands for HTML tags is unnecessary.
-
-There are a few exceptions and extensions to the Markdown [standard](http://daringfireball.net/projects/markdown/) that are documented in the Doxygen [documentation](http://www.stack.nl/~dimitri/doxygen/manual/markdown.html).
-
-### \`Backticks\`
-
-As is standard in Markdown and 'Github Flavoured Markdown' (GFM), backticks can be used to denote inline technical terms in the documentation, `like so`. In the documentation this will set the font to the monospaced 'console' typeface and will cause the enclosed term to stand out.
-
-However, fenced code blocks using 4 spaces or 3 backticks (\`\`\`) should be avoided as Doxygen will interpret these as \\code blocks and try to apply standard syntax colouring, which doesn't work so well for fish examples. Use `\fish..\endfish` blocks instead.
-
-### Lists
-
-Standard Markdown list rules apply, but as Doxygen will collapse white space on output, combined with the use of long lines, it's a good idea to include an extra new line between long list items to assist future editing.
-
-## Special cases
-
-The following can be used in \\fish blocks to render some fish scenarios. These are mostly used in the tutorial when an interactive situation needs to be displayed.
-
-### Custom formatting tags
-
-- `<s>`: auto\<s\>suggestion\</s\>.
-- `<m>`: \<m\>Matched\</m\> items, such as tab completions.
-- `<sm>`: Matched items \<sm\>searched\<sm\> for, like grep results.
-- `<error>`: \<error\>This would be shown as an error.\</error\>
-- `<asis>`: \<asis\>This test will not be parsed for fish markup.\</asis\>
-- `<outp>`: \<outp\>This would be rendered as command/script output.\</outp\>
-- `<bs>`: Render the contents with a preceding backslash. Useful when presenting output.
-- `{{` and `}}`: Required when wanting curly braces in regular expression example.
-
-### Prompts and cursors
-
-- `>_`: Display a basic prompt.
-- `~>_`: Display a prompt with a the home directory as the current working directory.
-- `___` (3 underscores): Display a cursor.
-
-
-### Keyboard shortcuts: @key{} and @cursor_key{}
-
-Graphical keyboard shortcuts can be defined using the following special commands. These allow for the different text requirements across the html and man pages. The HTML uses CSS to create a keyboard style, whereas the man page would display the key as text.
-
-- `@key{lable}`
-  Displays a key with a purely textual lable, such as: 'Tab', 'Page Up', 'Page Down', 'Home', 'End', 'F1', 'F19' and so on. 
-
-- `@key{modifier,lable}`
-  Displays a keystroke requiring the use of a 'modifier' key, such as 'Control-A', 'Shift-X', 'Alt-Tab' etc.
-
-- `@key{modifier,entity,lable}`
-  Displays a keystroke using a graphical entity, such as an arrow symbol for cursor key based shortcuts.
-
-- `@cursor_key{entity,lable}`
-  A special case for cursor keys, when no modifier is needed. i.e. `@cursor_key{&uarr;,up}` for the up arrow key.
-
-Some useful Unicode/HTML5 entities:
-
-- Up arrow: `&uarr;`
-- Down arrow: `&darr;`
-- Left arrow: `&larr;`
-- Right arrow `&rarr;`
-- Shift: `&#8679;`
-- Tab: `&rarrb;`
-- Mac option: `&#8997;`
-- Mac command: `&#8984;`
-
-## Notes
-
-### Doxygen
-
-Tested on:
-- Ubuntu 14.04 with Doxygen 1.8.8, built from [GitHub source](https://github.com/doxygen/doxygen.git).
-- CentOS 6.5 with Doxygen 1.8.8, built from [GitHub source](https://github.com/doxygen/doxygen.git).
-- Mac OS X 10.9 with Homebrew install Doxygen 1.8.7 and 1.8.8. 
-
-Graphviz was also installed in all the above testing.
-
-Doxygen 1.8.6 and lower do not have the \\htmlonly[block] directive which fixes a multitude of problems in the rendering of the docs. In Doxygen 1.8.7 the list of understood HTML entities was greatly increased. I tested earlier versions and many little issues returned.
-
-As fish ships with pre-built documentation, I don't see this as an issue.
-
-### Updated Configure/Makefile
-
-- Tested on Ubuntu 14.04, CentOS 6.5 and Mac OS X 10.9.
-- Makefile has GNU/BSD sed/grep detection.
-
-### HTML output
-
-- The output HTML is HTML5 compliant, but should quickly and elegantly degrade on older browsers without losing basic structure.
-- The CSS avoids the use or browser specific extenstions (i.e. -webkit, -moz etc), using the W3C HTML5 standard instead.
-- It's been tested in Chrome 37.0 and Firefox 32.0 on Mac OS X 10.9 (+Safari 7), Windows 8.1 (+Internet Explorer 11) and Ubuntu Desktop 14.04.
-- My assumption is basically that if someone cares enough to want to install fish, they'll be keeping a browser current.
-
-### Man page output
-
-- Tested on Ubuntu 14.04, CentOS 6.5 and Mac OS X 10.9.
-- Output is substantially cleaner.
-- Tested in cat, less, more and most pagers using the following fish script:
-
-```
-function manTest --description 'Test manpage' --argument page
-    set -l pager
-    for i in $argv
-        switch $i
-            case "-l"
-                set pager -P '/usr/bin/less -is'
-            case "-m"
-                set pager -P '/usr/bin/more -s'
-            case "-c"
-                set pager -P '/bin/cat'
-        end
-    end
-    man $pager ~/Projects/OpenSource/fish-shell/share/man/man1/$page.1
-end
-
-# Assumes 'most' is the default system pager.
-# NOT PORTABLE! Paths would be need to be updated on other systems.
-```
-
-### Developer docs and LATEX/PDF output
-
-- HTML developer docs tested on Ubuntu 14.04, CentOS 6.5 and Mac OS X 10.9.
-- LATEX/PDF reference manual tested on Mac OS X 10.9 using MacTEX. PDF production returns an error (due to Doxygen's use of an outdated 'float' package), but manual PDF output is ok.
-
-### Future changes
-
-1. The documentation creation process would be better if it could be modularised further and moved out of the makefile into a number of supporting scripts. This would allow both the automake and Xcode build processes to use the documentation scripts directly. 
-2. Remove the Doxygen dependency entirely for the user documentation. This would be very acheivable now that the bulk of the documentation is in Markdown.
-3. It would be useful to gauge what parts of the documentation are actually used by users. Judging by the amount of 'missing comment' errors during the developer docs build phase, this aspect of the docs has been rather neglected. If it is not longer used or useful, then this could change the future direction of the documentation and significantly streamline the process.

-\subsection abbr-description Description
-
-`abbr` manipulates the list of abbreviations that fish will expand.
-
-Abbreviations are user-defined character sequences or words that are replaced with longer phrases after they are entered. For example, a frequently-run command such as `git checkout` can be abbreviated to `gco`. After entering `gco` and pressing @key{Space} or @key{Enter}, the full text `git checkout` will appear in the command line.
-
-Abbreviations are stored using universal variables. You can create abbreviations directly on the command line, and they will be saved automatically. Calling `abbr -a` in config.fish will lead to slightly worse startup performance.
-
-The following parameters are available:
-
-- `-a WORD PHRASE` or `--add WORD PHRASE` Adds a new abbreviation, where WORD will be expanded to PHRASE.
-
-- `-s` or `--show` Show all abbreviated words and their expanded phrases in a manner suitable for export and import.
-
-- `-l` or `--list` Lists all abbreviated words.
-
-- `-e WORD` or `--erase WORD` Erase the abbreviation WORD.
-
-Note: fish version 2.1 supported `-a WORD=PHRASE`. This syntax is now deprecated but will still be converted.
-

-SEQUENCE is the character sequence to bind to. These should be written as <a href="index.html#escapes">fish escape sequences</a>. For example, because pressing the Alt key and another character sends that character prefixed with an escape character, Alt-based key bindings can be written using the `\e` escape. For example, @key{Alt,w} can be written as `\ew`. The control character can be written in much the same way using the `\c` escape, for example @key{Control,X} (^X) can be written as `\cx`. Note that Alt-based key bindings are case sensitive and Control-based key bindings are not. This is a constraint of text-based terminals, not `fish`.

-The default key binding can be set by specifying a `SEQUENCE` of the empty string (that is, ```''``` ). It will be used whenever no other binding matches. For most key bindings, it makes sense to use the `self-insert` function (i.e. ```bind '' self-insert```) as the default keybinding. This will insert any keystrokes not specifically bound to into the editor. Non- printable characters are ignored by the editor, so this will not result in control sequences being printable.

-If the `-k` switch is used, the name of the key (such as 'down', 'up' or 'backspace') is used instead of a sequence. The names used are the same as the corresponding curses variables, but without the 'key_' prefix. (See `terminfo(5)` for more information, or use `bind --key-names` for a list of all available named keys.)

-When `COMMAND` is a shellscript command, it is a good practice to put the actual code into a <a href="#function">function</a> and simply bind to the function name. This way it becomes significantly easier to test the function while editing, and the result is usually more readable as well.

-Key bindings are not saved between sessions by default. **Bare `bind` statements in <a href="index.html#initialization">config.fish</a> won't have any effect because it is sourced before the default keybindings are setup.** To save custom keybindings, put the `bind` statements into a function called `fish_user_key_bindings`, which will be <a href="tutorial.html#tut_autoload">autoloaded</a>.

-Key bindings may use "modes", which mimics Vi's modal input behavior. The default mode is "default", and every bind applies to a single mode. The mode can be viewed/changed with the `$fish_bind_mode` variable.

-\subsection special-case-escape Special Case: The escape Character
-
-The escape key can be used standalone, for example, to switch from insertion mode to normal mode when using Vi keybindings. Escape may also be used as a "meta" key, to indicate the start of an escape sequence, such as function or arrow keys. Custom bindings can also be defined that begin with an escape character.
-
-fish waits for a period after receiving the escape character, to determine whether it is standalone or part of an escape sequence. While waiting, additional key presses make the escape key behave as a meta key. If no other key presses come in, it is handled as a standalone escape. The waiting period is set to 300 milliseconds (0.3 seconds) in the default key bindings and 10 milliseconds in the vi key bindings. It can be configured by setting the `fish_escape_delay_ms` variable to a value between 10 and 5000 ms. It is recommended that this be a universal variable that you set once from an interactive session.
-
-Note: fish 2.2.0 and earlier used a default of 10 milliseconds, and provided no way to configure it. That effectively made it impossible to use escape as a meta key.

-- `SHORT_OPTION` is a one character option for the command.
+Command specific tab-completions in \c fish are based on the notion
+of options and arguments. An option is a parameter which begins with a
+hyphen, such as '-h', '-help' or '--help'. Arguments are parameters
+that do not begin with a hyphen. Fish recognizes three styles of
+options, the same styles as the GNU version of the getopt
+library. These styles are:
 
-- `LONG_OPTION` is a multi character option for the command.
+- Short options, like '-a'. Short options are a single character long, are preceded by a single hyphen and may be grouped together (like '-la', which is equivalent to '-l -a'). Option arguments may be specified in the following parameter ('-w 32') or by appending the option with the value ('-w32').
+- Old style long options, like '-Wall'. Old style long options can be more than one character long, are preceded by a single hyphen and may not be grouped together. Option arguments are specified in the following parameter ('-ao null').
+- GNU style long options, like '--colors'. GNU style long options can be more than one character long, are preceded by two hyphens, and may not be grouped together. Option arguments may be specified in the following parameter ('--quoting-style shell') or by appending the option with a '=' and the value ('--quoting-style=shell'). GNU style long options may be abbreviated so long as the abbreviation is unique ('--h' is equivalent to '--help' if help is the only long option beginning with an 'h').
 
-- `OPTION_ARGUMENTS` is parameter containing a space-separated list of possible option-arguments, which may contain command substitutions.
-
-- `DESCRIPTION` is a description of what the option and/or option arguments do.
-
-- `-c COMMAND` or `--command COMMAND` specifies that `COMMAND` is the name of the command.
-
-- `-p COMMAND` or `--path COMMAND` specifies that `COMMAND` is the absolute path of the program (optionally containing wildcards).
-
-- `-e` or `--erase` deletes the specified completion.
-
-- `-s SHORT_OPTION` or `--short-option=SHORT_OPTION` adds a short option to the completions list.
-
-- `-l LONG_OPTION` or `--long-option=LONG_OPTION` adds a GNU style long option to the completions list.
-
-- `-o LONG_OPTION` or `--old-option=LONG_OPTION` adds an old style long option to the completions list (See below for details).
-
-- `-a OPTION_ARGUMENTS` or `--arguments=OPTION_ARGUMENTS` adds the specified option arguments to the completions list.
-
-- `-f` or `--no-files` specifies that the options specified by this completion may not be followed by a filename.
-
-- `-r` or `--require-parameter` specifies that the options specified by this completion always must have an option argument, i.e. may not be followed by another option.
-
-- `-x` or `--exclusive` implies both `-r` and `-f`.
-
-- `-w WRAPPED_COMMAND` or `--wraps=WRAPPED_COMMAND` causes the specified command to inherit completions from the wrapped command (See blow for details).
-
-- `-n` or `--condition` specifies a shell command that must return 0 if the completion is to be used. This makes it possible to specify completions that should only be used in some cases.
-
-- `-CSTRING` or `--do-complete=STRING` makes complete try to find all possible completions for the specified string.
-
-- `-C` or `--do-complete` with no argument makes complete try to find all possible completions for the current command line buffer. If the shell is not in interactive mode, an error is returned.

-
-The options for specifying command switches and wrapped commands may be used multiple times to define multiple completions for the command(s) in a single call.

-When `-a` or `--arguments` is specified in conjunction with long, short, or old style options, the specified arguments are only used as completions when attempting to complete an argument for any of the specified options. If `-a` or `--arguments` is specified without any long, short, or old style options, the specified arguments are used when completing any argument to the command (except when completing an option argument that was specified with `-r` or `--require-parameter`).
-
-Command substitutions found in `OPTION_ARGUMENTS` are not expected to return a space-separated list of arguments. Instead they must return a newline-separated list of arguments, and each argument may optionally have a tab character followed by the argument description. Any description provided in this way overrides a description given with `-d` or `--description`.
-
-The `-w` or `--wraps` options causes the specified command to inherit completions from another command. The inheriting command is said to "wrap" the inherited command. The wrapping command may have its own completions in addition to inherited ones. A command may wrap multiple commands, and wrapping is transitive: if A wraps B, and B wraps C, then A automatically inherits all of C's completions. Wrapping can be removed using the `-e` or `--erase` options. Note that wrapping only works for completions specified with `-c` or `--command` and are ignored when specifying completions with `-p` or `--path`.
-
-When erasing completions, it is possible to either erase all completions for a specific command by specifying `complete -c COMMAND -e`, or by specifying a specific completion option to delete by specifying either a long, short or old style option.
+The options for specifying command name, command path, or command
+switches may all be used multiple times to specify multiple commands
+which have the same completion or multiple switches accepted by a
+command.
 
+When erasing completions, it is possible to either erase all
+completions for a specific command by specifying <tt>complete -e -c
+COMMAND</tt>, or by specifying a specific completion option to delete
+by specifying either a long, short or old style option.
 
 \subsection complete-example Example
 
-The short style option `-o` for the `gcc` command requires that a file follows it.  This can be done using writing:
+The short style option <tt>-o</tt> for the \c gcc command requires
+that a file follows it.  This can be done using writing <tt>complete
+-c gcc -s o -r</tt>.
 
-\fish
-complete -c gcc -s o -r
-\endfish
+The short style option <tt>-d</tt> for the \c grep command requires
+that one of the strings 'read', 'skip' or 'recurse' is used.  This can
+be specified writing <tt>complete -c grep -s d -x -a "read skip
+recurse"</tt>.
 
-The short style option `-d` for the `grep` command requires that one of the strings '`read`', '`skip`' or '`recurse`' is used.  This can be specified writing:
+The \c su command takes any username as an argument. Usernames are
+given as the first colon-separated field in the file /etc/passwd. This
+can be specified as: <tt>complete -x -c su -d "Username" -a "(cat
+/etc/passwd|cut -d : -f 1)" </tt>.
 
-\fish
-complete -c grep -s d -x -a "read skip recurse"
-\endfish
-
-The `su` command takes any username as an argument. Usernames are given as the first colon-separated field in the file /etc/passwd. This can be specified as:
-
-\fish
-complete -x -c su -d "Username" -a "(cat /etc/passwd | cut -d : -f 1)"
-\endfish
-
-The `rpm` command has several different modes. If the `-e` or `--erase` flag has been specified, `rpm` should delete one or more packages, in which case several switches related to deleting packages are valid, like the `nodeps` switch.
+The \c rpm command has several different modes. If the \c -e or \c
+--erase flag has been specified, \c rpm should delete one or more
+packages, in which case several switches related to deleting packages
+are valid, like the \c nodeps switch.
 
 This can be written as:
 
-\fish
-complete -c rpm -n "__fish_contains_opt -s e erase" -l nodeps -d "Don't check dependencies"
-\endfish
+<tt>complete -c rpm -n "__fish_contains_opt -s e erase" -l nodeps -d
+"Don't check dependencies"</tt>
 
-where `__fish_contains_opt` is a function that checks the command line buffer for the presence of a specified set of options.
-
-To implement an alias, use the `-w` or `--wraps` option:
-
-\fish
-complete -c hub -w git
-\endfish
-
-Now hub inherits all of the completions from git. Note this can also be specified in a function declaration.

 \section ortho The law of orthogonality
 
-The shell language should have a small set of orthogonal features. Any situation where two features are related but not identical, one of them should be removed, and the other should be made powerful and general enough to handle all common use cases of either feature.

 Rationale:
 
-Related features make the language larger, which makes it harder to learn. It also increases the size of the source code, making the program harder to maintain and update.

-\section design-response The law of responsiveness
+\section sep The law of responsiveness
 
 The shell should attempt to remain responsive to the user at all times, even in the face of contended or unresponsive filesystems. It is only acceptable to block in response to a user initiated action, such as running a command.
 
 Rationale:
+
 Bad performance increases user-facing complexity, because it trains users to recognize and route around slow use cases. It is also incredibly frustrating.
 
 Examples:
 
 - Features like syntax highlighting and autosuggestions must perform all of their disk I/O asynchronously.
-
 - Startup should minimize forks and disk I/O, so that fish can be started even if the system is under load.
 
-\section design-configurability Configurability is the root of all evil
+\section conf Configurability is the root of all evil
 
-Every configuration option in a program is a place where the program is too stupid to figure out for itself what the user really wants, and should be considered a failure of both the program and the programmer who implemented it.
+Every configuration option in a program is a place where the program
+is too stupid to figure out for itself what the user really wants, and
+should be considered a failiure of both the program and the programmer
+who implemented it.
 
 Rationale:
-Different configuration options are a nightmare to maintain, since the number of potential bugs caused by specific configuration combinations quickly becomes an issue. Configuration options often imply assumptions about the code which change when reimplementing the code, causing issues with backwards compatibility. But mostly, configuration options should be avoided since they simply should not exist, as the program should be smart enough to do what is best, or at least a good enough approximation of it.

+options should be avoided since they simply should not exist, as the
+program should be smart enough to do what is best, or at least a good
+enough approximation of it.
 
 Examples:
 
 - Fish allows the user to set various syntax highlighting colors. This is needed because fish does not know what colors the terminal uses by default, which might make some things unreadable. The proper solution would be for text color preferences to be defined centrally by the user for all programs, and for the terminal emulator to send these color properties to fish.
-
 - Fish does not allow you to set the history filename, the number of history entries, different language substyles or any number of other common shell configuration options.
 
-A special note on the evils of configurability is the long list of very useful features found in some shells, that are not turned on by default. Both zsh and bash support command-specific completions, but no such completions are shipped with bash by default, and they are turned off by default in zsh. Other features that zsh supports that are disabled by default include tab-completion of strings containing wildcards, a sane completion pager and a history file.

 \section user The law of user focus
 
-When designing a program, one should first think about how to make a intuitive and powerful program. Implementation issues should only be considered once a user interface has been designed.
+When designing a program, one should first think about how to make a
+intuitive and powerful program. Implementation issues should only be
+considered once a user interface has been designed.
 
 Rationale:
 
-This design rule is different than the others, since it describes how one should go about designing new features, not what the features should be. The problem with focusing on what can be done, and what is easy to do, is that too much of the implementation is exposed. This means that the user must know a great deal about the underlying system to be able to guess how the shell works, it also means that the language will often be rather low-level.

+to be able to guess how the shell works, it also means that the
+language will often be rather low-level.
 
 Examples:
+
 - There should only be one type of input to the shell, lists of commands. Loops, conditionals and variable assignments are all performed through regular commands.
-
-- The differences between built-in commands and shellscript functions should be made as small as possible. Built-ins and shellscript functions should have exactly the same types of argument expansion as other commands, should be possible to use in any position in a pipeline, and should support any I/O redirection.

 - Instead of forking when performing command substitution to provide a fake variable scope, all fish commands are performed from the same process, and fish instead supports true scoping.
-
-- All blocks end with the `end` built-in.
+- All blocks end with the \c end builtin.
 
 \section disc The law of discoverability
 
-A program should be designed to make its features as easy as possible to discover for the user.
+A program should be designed to make its features as
+easy as possible to discover for the user.
 
 Rationale:
-A program whose features are discoverable turns a new user into an expert in a shorter span of time, since the user will become an expert on the program simply by using it.
 
-The main benefit of a graphical program over a command-line-based program is discoverability. In a graphical program, one can discover all the common features by simply looking at the user interface and guessing what the different buttons, menus and other widgets do. The traditional way to discover features in command-line programs is through manual pages. This requires both that the user starts to use a different program, and then they remember the new information until the next time they use the same program.

 Examples:

 - Everything should be tab-completable, and every tab completion should have a description.

+- Every syntax error and error in a builtin command should contain an error message describing what went wrong and a relevant help page. Whenever possible, errors should be flagged red by the syntax highlighter.
 - The help manual should be easy to read, easily available from the shell, complete and contain many examples

-- The language should be uniform, so that once the user understands the command/argument syntax, they will know the whole language, and be able to use tab-completion to discover new features.

 \section faq-cwd-symlink Why does cd, $PWD and and various fish commands always resolve symlinked directories to their canonical path?
 
-<i>For example if `~/images` is a symlink to `~/Documents/Images`, if I write '`cd images`', my prompt will say `~/Documents/Images`, not `~/images`.</i>
+<i>
+For example if ~/images is a symlink to ~/Documents/Images, if I write
+'cd images', my prompt will say ~/D/Images, not ~/images.
+</i>
 
-Because it is impossible to consistently keep symlinked directories unresolved. It is indeed possible to do this partially, and many other shells do so. But it was felt there are enough serious corner cases that this is a bad idea. Most such issues have to do with how '..' is handled, and are variations of the following example:

-Writing `cd images; ls ..` given the above directory structure would list the contents of `~/Documents`, not of `~`, even though using `cd ..` changes the current directory to `~`, and the prompt, the `pwd` builtin and many other directory information sources suggest that the current directory is `~/images` and its parent is `~`. This issue is not possible to fix without either making every single command into a builtin, breaking Unix semantics or implementing kludges in every single command. This issue can also be seen when doing IO redirection.

-Another related issue is that many programs that operate on recursive directory trees, like the find command, silently ignore symlinked directories. For example, ```find $PWD -name '*.txt'``` silently fails in shells that don't resolve symlinked paths.

 \section faq-cd-implicit I accidentally entered a directory path and fish changed directory. What happened?
 
-If fish is unable to locate a command with a given name, and it starts with '`.`', '`/`' or '`~`', fish will test if a directory of that name exists. If it does, it is implicitly assumed that you want to change working directory. For example, the fastest way to switch to your home directory is to simply press `~` and enter.

 \section faq-open The open command doesn't work.
 
-The `open` command uses the MIME type database and the `.desktop` files used by Gnome and KDE to identify filetypes and default actions. If at least one of these environments is installed, but the open command is not working, this probably means that the relevant files are installed in a non-standard location. Consider <a href="index.html#more-help">asking for more help</a>.

 \section faq-titlebar I'm seeing weird output before each prompt when using screen. What's wrong?
 
 Quick answer:
 
 Run the following command in fish:
 
-\fish{cli-dark}
-function fish_title; end; funcsave fish_title
-\endfish
+<pre>
+echo 'function fish_title;end' &gt; ~/.config/fish/config.fish
+</pre>
 
 Problem solved!
 
 The long answer:
 
-Fish is trying to set the titlebar message of your terminal. While screen itself supports this feature, your terminal does not. Unfortunately, when the underlying terminal doesn't support setting the titlebar, screen simply passes through the escape codes and text to the underlying terminal instead of ignoring them. It is impossible to detect and resolve this problem from inside fish since fish has no way of knowing what the underlying terminal type is. For now, the only way to fix this is to unset the titlebar message, as suggested above.

 \section faq-history Why doesn't history substitution ("!$" etc.) work?
 
-Because history substitution is an awkward interface that was invented before interactive line editing was even possible.  Fish drops it in favor of perfecting the interactive history recall interface.  Switching requires a small change of habits: if you want to modify an old line/word, first recall it, then edit.  E.g. don't type "sudo !!" - first press Up, then Home, then type "sudo ".

+it, then edit.  E.g. don't type "sudo !!" - first press Up, then Home, then
+type "sudo ".
 
 Fish history recall is very simple yet effective:
 
-- As in any modern shell, the Up arrow, @cursor_key{&uarr;,Up} recalls whole lines, starting from the last line executed.  A single press replaces "!!", later presses replace "!-3" and the like.
-
-  - If the line you want is far back in the history, type any part of the line and then press Up one or more times.  This will constrain the recall to lines that include this text, and you will get to the line you want much faster.  This replaces "!vi", "!?bar.c" and the like.
-
-- @key{Alt,&uarr;,Up} recalls individual arguments, starting from the last argument in the last line executed.  A single press replaces "!$", later presses replace "!!:4" and the like.
-
-  - If the argument you want is far back in history (e.g. 2 lines back - that's a lot of words!), type any part of it and then press @key{Alt,&uarr;,Up}.  This will show only arguments containing that part and you will get what you want much faster.  Try it out, this is very convenient!
-
-  - If you want to reuse several arguments from the same line ("!!:3*" and the like), consider recalling the whole line and removing what you don't need (@key{Alt,D} and @key{Alt,Backspace} are your friends).
