# ZSH Completion for conda (http://conda.pydata.org/)
#
# Author: Valentin Haenel <valentin@haenel.co> (https://github.com/esc/)
# Licence: WTFPL (http://sam.zoy.org/wtfpl/)
# Version: 0.10-dev
# Homepage: https://github.com/esc/conda-zsh-completion
# Demo: https://asciinema.org/a/16516
#
# This completion depends on Python for a json parser, sorry. Unfortunately
# there is no such thing in zsh (yet).
#
# To use this completion, install it somewhere on your hard drive:
#
# $ git clone https://github.com/esc/conda-zsh-completion
#
# And then add it to your $fpath in ~/.zshrc before you call compinit:
#
# fpath+=/path/to/where/you/installed/conda-zsh-completion
# compinit
#
# If you're using oh-my-zsh or Prezto, they will call compinit for you, so
# just add it to your $fpath before calling the OMZ or Prezto initialization
# functions. For example:
#
# git clone https://github.com/esc/conda-zsh-completion ${ZSH_CUSTOM:=~/.oh-my-zsh/custom}/plugins/conda-zsh-completion
#
# And add lines in `.zshrc`
# plugins=(… conda-zsh-completion)
# autoload -U compinit && compinit
#
# If you use oh-my-zsh, you might have to move the "autoload" line to after you sourced
# oh-my-zsh.sh.
#
# To activate the completion cache for packages, add the following to your
# '.zshrc':
#
# zstyle ':completion::complete:*' use-cache 1
#
# To display subcommand completion in groups, please add the following to your
# '.zshrc':
#
# zstyle ":conda_zsh_completion:*" use-groups true
#
# To display unnamed environments and prefixes of environments, add the following
# to your '.zshrc':
#
# zstyle ":conda_zsh_completion:*" show-unnamed true
#
# To display environments autocompletion sorted in creation order add the following
# to your '.zshrc':
#
# zstyle ":conda_zsh_completion:*" sort-envs-by-time true
#
# The completion will display both global environments (envs located in conda_dir/envs and base env)
# and local environments (located in ~/.conda/envs).
# If enables sort-envs-by-time, it will display local environments first.
# To display global environments first, add the following to your '.zshrc':
#
# zstyle ":conda_zsh_completion:*" show-global-envs-first true
#
# If not enables sort-envs-by-time, then all environments will be sorted by alphabetical order,
# and this option is useless.
#
# To forcefully clean the completion cache, look in '~/.zcompcache' and remove
# file starting with 'conda_'. And/or do 'rm ~/.zcompdump*'.
#
# When developing, you can use the following to reload the completion after
# having modified it:
#
# $ unfunction _conda && autoload -U _conda
#
# Please report any issues at:
# https://github.com/esc/conda-zsh-completion/issues
#
# CHANGELOG
# ---------
# * v0.10
#
# * XXX
#
# * v0.9
#
# * Improved the completion speed for completing environments, thanks to
# Niels Mündler.
# * Various minor improvements and documentation upgrades
#
# * v0.8
#
# * Updated installation instructions and added a license file, thanks to
# Andrew Janke
#
# * v0.7
#
# * Fix alignment during menu-completion
#
# * v0.6
#
# * conda activate and conda deactivate can now be completed, thanks to
# Taylor Kang Beck
#
# * v0.5
#
# * conda-env can now be completed
# * conda-build can now be completed
#
# * v0.4
#
# * conda info can complete available packages
# * conda install and create have rudimentary package version completion
# * remove caching for local package list, it's fast enough
# * conda remove and update are aware of -n or similar and complete only
# packages in the given environment
# * list of packages excludes those installed with pip
#
# * v0.3
#
# * overhaul of the completion for config
#
# * complete only existing keys
# * complete only existing values
# * differentiate between list and boolean config
# * reader and writer options mutually exclusive
# * complete multiple keys for --get
#
# * -n,--name and -p,--prefix are now mutually exclusive
#
# * v0.2
#
# * completion cache for packages
# * complete all channels defined in .condarc
#
# * v0.1
#
# * inital release
#
# TODO
# ----
#
# * Subcommand grouping is still alpha.
# * Example of activating cache only for conda completion
# * Make cache policy configurable
# * Completion for version numbers is rudimentary:
# only 'install' can complete them and only for a single '=' sign
# * Configuration for external commands: only build and env supported
# * Properly handle package specs on the command line
# * Don't continue to complete options once -- is given
# * None of the commands are aware of channels

# zsh-autopair
A simple plugin that auto-closes, deletes and skips over matching delimiters in
zsh intelligently. Hopefully.
> NOTE: zsh-autopair is untested for versions of Zsh below 5.0.2. Please report
> any issues you have in earlier versions!
Specifically, zsh-autopair does 5 things for you:
1. It inserts matching pairs (by default, that means brackets, quotes and
spaces):
e.g. `echo |` => <kbd>"</kbd> => `echo "|"`
2. It skips over matched pairs:
e.g. `cat ./*.{py,rb|}` => <kbd>}</kbd> => `cat ./*.{py,rb}|`
3. It auto-deletes pairs on backspace:
e.g. `git commit -m "|"` => <kbd>backspace</kbd> => `git commit -m |`
4. And does all of the above only when it makes sense to do so. e.g. when the
pair is balanced and when the cursor isn't next to a boundary character:
e.g. `echo "|""` => <kbd>backspace</kbd> => `echo |""` (doesn't aggressively eat up too many quotes)
5. Spaces between brackets are expanded and contracted.
e.g. `echo [|]` => <kbd>space</kbd> => `echo [ | ]` => <kbd>backspace</kbd> => `echo [|]`

## Install
Download and source `autopair.zsh`
```bash
if [[ ! -d ~/.zsh-autopair ]]; then
git clone https://github.com/hlissner/zsh-autopair ~/.zsh-autopair
fi
source ~/.zsh-autopair/autopair.zsh
autopair-init
```
### Antigen
`antigen bundle hlissner/zsh-autopair`
### zgen
```bash
if ! zgen saved; then
echo "Creating a zgen save"
# ... other plugins
zgen load hlissner/zsh-autopair
zgen save
fi
```
### zplug
Load autopair _after compinit_, otherwise, the plugin won't work.
```bash
zplug "hlissner/zsh-autopair", defer:2
```
## Configuration
zsh-autopair sets itself up. You can prevent this by setting
`AUTOPAIR_INHIBIT_INIT`.
**Options:**
* `AUTOPAIR_BETWEEN_WHITESPACE` (default: blank): if set, regardless of whether
delimiters are unbalanced or do not meet a boundary check, pairs will be
auto-closed if surrounded by whitespace, BOL or EOL.
* `AUTOPAIR_INHIBIT_INIT` (default: blank): if set, autopair will not
automatically set up keybinds. [Check out the initialization
code](autopair.zsh#L118) if you want to know what it does.
* `AUTOPAIR_PAIRS` (default: ``('`' '`' "'" "'" '"' '"' '{' '}' '[' ']' '(' ')'
' ' ' ')``): An associative array that map pairs. Only one-character pairs are
supported. To modify this, see the "Adding/Removing pairs" section.
* `AUTOPAIR_LBOUNDS`/`AUTOPAIR_RBOUNDS` (default: see below): Associative lists
of regex character groups dictating the 'boundaries' for autopairing depending
on the delimiter. These are their default values:
```bash
AUTOPAIR_LBOUNDS=(all '[.:/\!]')
AUTOPAIR_LBOUNDS+=(quotes '[]})a-zA-Z0-9]')
AUTOPAIR_LBOUNDS+=(spaces '[^{([]')
AUTOPAIR_LBOUNDS+=(braces '')
AUTOPAIR_LBOUNDS+=('`' '`')
AUTOPAIR_LBOUNDS+=('"' '"')
AUTOPAIR_LBOUNDS+=("'" "'")
AUTOPAIR_RBOUNDS=(all '[[{(<,.:?/%$!a-zA-Z0-9]')
AUTOPAIR_RBOUNDS+=(quotes '[a-zA-Z0-9]')
AUTOPAIR_RBOUNDS+=(spaces '[^]})]')
AUTOPAIR_RBOUNDS+=(braces '')
```
For example, if `$AUTOPAIR_LBOUNDS[braces]="[a-zA-Z]"`, then braces (`{([`) won't be
autopaired if the cursor follows an alphabetical character.
Individual delimiters can be used too. Setting `$AUTOPAIR_RBOUNDS['{']="[0-9]"` will
cause <kbd>{</kbd> specifically to not be autopaired when the cursor precedes a number.
### Adding/Removing pairs
You can change the designated pairs in zsh-autopair by modifying the
`AUTOPAIR_PAIRS` envvar. This can be done _before_ initialization like so:
``` sh
typeset -gA AUTOPAIR_PAIRS
AUTOPAIR_PAIRS+=("<" ">")
```
Or after initialization; however, you'll have to bind keys to `autopair-insert`
manually:
```sh
AUTOPAIR_PAIRS+=("<" ">")
bindkey "<" autopair-insert
# prevents breakage in isearch
bindkey -M isearch "<" self-insert
```
To _remove_ pairs, use `unset 'AUTOPAIR_PAIRS[<]'`. Unbinding is optional.
## Troubleshooting & compatibility issues
### zgen & prezto compatibility
Prezto's Editor module is known to reset autopair's bindings. A workaround is to
_defer autopair from initializing_ (by setting `AUTOPAIR_INHIBIT_INIT=1`) and
initialize it manually (by calling `autopair-init`):
``` sh
source "$HOME/.zgen/zgen.zsh"
# Add this
AUTOPAIR_INHIBIT_INIT=1
if ! zgen saved; then
zgen prezto
# ...
zgen load hlissner/zsh-autopair 'autopair.zsh'
#...
zgen save
fi
# And this
autopair-init
```
### text on right-side of cursor interfere with completion
Bind <kbd>Tab</kbd> to `expand-or-complete-prefix` and completion will ignore
what's to the right of cursor:
`bindkey '^I' expand-or-complete-prefix`
This has the unfortunate side-effect of overwriting whatever's right of the
cursor, however.
### zsh-autopair & isearch?
zsh-autopair silently disables itself in isearch, as the two are incompatible.
### Midnight Commander
MC hangs when zsh-autopair tries to bind the space key. This also breaks the MC
subshell.
Disable space expansion to work around this: `unset 'AUTOPAIR_PAIRS[ ]'`
## Other resources
* Works wonderfully with [zsh-syntax-highlight] and
`ZSH_HIGHLIGHT_HIGHLIGHTERS+=brackets`, but zsh-syntax-highlight must be
loaded *after* zsh-autopair.
* Mixes well with these vi-mode zsh modules: [surround], [select-quoted], and
[select-bracketed] (they're built into zsh as of zsh-5.0.8)

# zsh-autosuggestions
_[Fish](http://fishshell.com/)-like fast/unobtrusive autosuggestions for zsh._
It suggests commands as you type based on history and completions.
Requirements: Zsh v4.3.11 or later

<a href="https://asciinema.org/a/37390" target="_blank"><img src="https://asciinema.org/a/37390.png" width="400" /></a>
## Installation
See [INSTALL.md](INSTALL.md).
## Usage
As you type commands, you will see a completion offered after the cursor in a muted gray color. This color can be changed by setting the `ZSH_AUTOSUGGEST_HIGHLIGHT_STYLE` variable. See [configuration](#configuration).
If you press the <kbd></kbd> key (`forward-char` widget) or <kbd>End</kbd> (`end-of-line` widget) with the cursor at the end of the buffer, it will accept the suggestion, replacing the contents of the command line buffer with the suggestion.
If you invoke the `forward-word` widget, it will partially accept the suggestion up to the point that the cursor moves to.
## Configuration
You may want to override the default global config variables. Default values of these variables can be found [here](src/config.zsh).
**Note:** If you are using Oh My Zsh, you can put this configuration in a file in the `$ZSH_CUSTOM` directory. See their comments on [overriding internals](https://github.com/robbyrussell/oh-my-zsh/wiki/Customization#overriding-internals).
### Suggestion Highlight Style
Set `ZSH_AUTOSUGGEST_HIGHLIGHT_STYLE` to configure the style that the suggestion is shown with. The default is `fg=8`, which will set the foreground color to color 8 from the [256-color palette](https://upload.wikimedia.org/wikipedia/commons/1/15/Xterm_256color_chart.svg). If your terminal only supports 8 colors, you will need to use a number between 0 and 7.
Background color can also be set, and the suggestion can be styled bold, underlined, or standout. For example, this would show suggestions with bold, underlined, pink text on a cyan background:
```sh
ZSH_AUTOSUGGEST_HIGHLIGHT_STYLE="fg=#ff00ff,bg=cyan,bold,underline"
```
For more info, read the Character Highlighting section of the zsh manual: `man zshzle` or [online](http://zsh.sourceforge.net/Doc/Release/Zsh-Line-Editor.html#Character-Highlighting).
**Note:** Some iTerm2 users have reported [not being able to see the suggestions](https://github.com/zsh-users/zsh-autosuggestions/issues/416#issuecomment-486516333). If this affects you, the problem is likely caused by incorrect color settings. In order to correct this, go into iTerm2's setting, navigate to profile > colors and make sure that the colors for Basic Colors > Background and ANSI Colors > Bright Black are **different**.
### Suggestion Strategy
`ZSH_AUTOSUGGEST_STRATEGY` is an array that specifies how suggestions should be generated. The strategies in the array are tried successively until a suggestion is found. There are currently three built-in strategies to choose from:
- `history`: Chooses the most recent match from history.
- `completion`: Chooses a suggestion based on what tab-completion would suggest. (requires `zpty` module)
- `match_prev_cmd`: Like `history`, but chooses the most recent match whose preceding history item matches the most recently executed command ([more info](src/strategies/match_prev_cmd.zsh)). Note that this strategy won't work as expected with ZSH options that don't preserve the history order such as `HIST_IGNORE_ALL_DUPS` or `HIST_EXPIRE_DUPS_FIRST`.
For example, setting `ZSH_AUTOSUGGEST_STRATEGY=(history completion)` will first try to find a suggestion from your history, but, if it can't find a match, will find a suggestion from the completion engine.
### Widget Mapping
This plugin works by triggering custom behavior when certain [zle widgets](http://zsh.sourceforge.net/Doc/Release/Zsh-Line-Editor.html#Zle-Widgets) are invoked. You can add and remove widgets from these arrays to change the behavior of this plugin:
- `ZSH_AUTOSUGGEST_CLEAR_WIDGETS`: Widgets in this array will clear the suggestion when invoked.
- `ZSH_AUTOSUGGEST_ACCEPT_WIDGETS`: Widgets in this array will accept the suggestion when invoked.
- `ZSH_AUTOSUGGEST_EXECUTE_WIDGETS`: Widgets in this array will execute the suggestion when invoked.
- `ZSH_AUTOSUGGEST_PARTIAL_ACCEPT_WIDGETS`: Widgets in this array will partially accept the suggestion when invoked.
- `ZSH_AUTOSUGGEST_IGNORE_WIDGETS`: Widgets in this array will not trigger any custom behavior.
Widgets that modify the buffer and are not found in any of these arrays will fetch a new suggestion after they are invoked.
**Note:** A widget shouldn't belong to more than one of the above arrays.
### Disabling suggestion for large buffers
Set `ZSH_AUTOSUGGEST_BUFFER_MAX_SIZE` to an integer value to disable autosuggestion for large buffers. The default is unset, which means that autosuggestion will be tried for any buffer size. Recommended value is 20.
This can be useful when pasting large amount of text in the terminal, to avoid triggering autosuggestion for strings that are too long.
### Asynchronous Mode
Suggestions are fetched asynchronously by default in zsh versions 5.0.8 and greater. To disable asynchronous suggestions and fetch them synchronously instead, `unset ZSH_AUTOSUGGEST_USE_ASYNC` after sourcing the plugin.
Alternatively, if you are using a version of zsh older than 5.0.8 and want to enable asynchronous mode, set the `ZSH_AUTOSUGGEST_USE_ASYNC` variable after sourcing the plugin (it can be set to anything). Note that there is [a bug](https://github.com/zsh-users/zsh-autosuggestions/issues/364#issuecomment-481423232) in versions of zsh older than 5.0.8 where <kbd>ctrl</kbd> + <kbd>c</kbd> will fail to reset the prompt immediately after fetching a suggestion asynchronously.
### Disabling automatic widget re-binding
Set `ZSH_AUTOSUGGEST_MANUAL_REBIND` (it can be set to anything) to disable automatic widget re-binding on each precmd. This can be a big boost to performance, but you'll need to handle re-binding yourself if any of the widget lists change or if you or another plugin wrap any of the autosuggest widgets. To re-bind widgets, run `_zsh_autosuggest_bind_widgets`.
### Ignoring history suggestions that match a pattern
Set `ZSH_AUTOSUGGEST_HISTORY_IGNORE` to a [glob pattern](http://zsh.sourceforge.net/Doc/Release/Expansion.html#Glob-Operators) to prevent offering suggestions for history entries that match the pattern. For example, set it to `"cd *"` to never suggest any `cd` commands from history. Or set to `"?(#c50,)"` to never suggest anything 50 characters or longer.
**Note:** This only affects the `history` and `match_prev_cmd` suggestion strategies.
### Skipping completion suggestions for certain cases
Set `ZSH_AUTOSUGGEST_COMPLETION_IGNORE` to a [glob pattern](http://zsh.sourceforge.net/Doc/Release/Expansion.html#Glob-Operators) to prevent offering completion suggestions when the buffer matches that pattern. For example, set it to `"git *"` to disable completion suggestions for git subcommands.
**Note:** This only affects the `completion` suggestion strategy.
### Key Bindings
This plugin provides a few widgets that you can use with `bindkey`:
1. `autosuggest-accept`: Accepts the current suggestion.
2. `autosuggest-execute`: Accepts and executes the current suggestion.
3. `autosuggest-clear`: Clears the current suggestion.
4. `autosuggest-fetch`: Fetches a suggestion (works even when suggestions are disabled).
5. `autosuggest-disable`: Disables suggestions.
6. `autosuggest-enable`: Re-enables suggestions.
7. `autosuggest-toggle`: Toggles between enabled/disabled suggestions.
For example, this would bind <kbd>ctrl</kbd> + <kbd>space</kbd> to accept the current suggestion.
```sh
bindkey '^ ' autosuggest-accept
```
## Troubleshooting
If you have a problem, please search through [the list of issues on GitHub](https://github.com/zsh-users/zsh-autosuggestions/issues?q=) to see if someone else has already reported it.
### Reporting an Issue
Before reporting an issue, please try temporarily disabling sections of your configuration and other plugins that may be conflicting with this plugin to isolate the problem.
When reporting an issue, please include:
- The smallest, simplest `.zshrc` configuration that will reproduce the problem. See [this comment](https://github.com/zsh-users/zsh-autosuggestions/issues/102#issuecomment-180944764) for a good example of what this means.
- The version of zsh you're using (`zsh --version`)
- Which operating system you're running
## Uninstallation
1. Remove the code referencing this plugin from `~/.zshrc`.
2. Remove the git repository from your hard drive
```sh
rm -rf ~/.zsh/zsh-autosuggestions # Or wherever you installed
```
## Development
### Build Process
Edit the source files in `src/`. Run `make` to build `zsh-autosuggestions.zsh` from those source files.
### Pull Requests
Pull requests are welcome! If you send a pull request, please:
- Request to merge into the `develop` branch (*NOT* `master`)
- Match the existing coding conventions.
- Include helpful comments to keep the barrier-to-entry low for people new to the project.
- Write tests that cover your code as much as possible.
### Testing
Tests are written in ruby using the [`rspec`](http://rspec.info/) framework. They use [`tmux`](https://tmux.github.io/) to drive a pseudoterminal, sending simulated keystrokes and making assertions on the terminal content.
Test files live in `spec/`. To run the tests, run `make test`. To run a specific test, run `TESTS=spec/some_spec.rb make test`. You can also specify a `zsh` binary to use by setting the `TEST_ZSH_BIN` environment variable (ex: `TEST_ZSH_BIN=/bin/zsh make test`).
A docker image for testing is available [on docker hub](https://hub.docker.com/r/ericfreese/zsh-autosuggestions-test). It comes with ruby, the bundler dependencies, and all supported versions of zsh installed.
Pull the docker image with:
```sh
docker pull ericfreese/zsh-autosuggestions-test
```
To run the tests for a specific version of zsh (where `<version>` below is substituted with the contents of a line from the [`ZSH_VERSIONS`](ZSH_VERSIONS) file):
```sh
docker run -it -e TEST_ZSH_BIN=zsh-<version> -v $PWD:/zsh-autosuggestions zsh-autosuggestions-test make test
```

Hacking on zsh-syntax-highlighting itself
=========================================
This document includes information for people working on z-sy-h itself: on the
core driver (`zsh-syntax-highlighting.zsh`), on the highlighters in the
distribution, and on the test suite. It does not target third-party
highlighter authors (although they may find it an interesting read).
The `main` highlighter
----------------------
The following function `pz` is useful when working on the `main` highlighting:
```zsh
pq() {
(( $#argv )) || return 0
print -r -l -- ${(qqqq)argv}
}
pz() {
local arg
for arg; do
pq ${(z)arg}
done
}
```
It prints, for each argument, its token breakdown, similar to how the main
loop of the `main` highlighter sees it.
Testing the `brackets` highlighter
----------------------------------
Since the test harness empties `ZSH_HIGHLIGHT_STYLES` and the `brackets`
highlighter interrogates `ZSH_HIGHLIGHT_STYLES` to determine how to highlight,
tests must set the `bracket-level-#` keys themselves. For example:
```zsh
ZSH_HIGHLIGHT_STYLES[bracket-level-1]=
ZSH_HIGHLIGHT_STYLES[bracket-level-2]=
BUFFER='echo ({x})'
expected_region_highlight=(
"6 6 bracket-level-1" # (
"7 7 bracket-level-2" # {
"9 9 bracket-level-2" # }
"10 10 bracket-level-1" # )
)
```
Testing the `pattern` and `regexp` highlighters
-----------------------------------------------
Because the `pattern` and `regexp` highlighters modifies `region_highlight`
directly instead of using `_zsh_highlight_add_highlight`, the test harness
cannot get the `ZSH_HIGHLIGHT_STYLES` keys. Therefore, when writing tests, use
the style itself as third word (cf. the
[documentation for `expected_region_highlight`](docs/highlighters.md)). For example:
```zsh
ZSH_HIGHLIGHT_PATTERNS+=('rm -rf *' 'fg=white,bold,bg=red')
BUFFER='rm -rf /'
expected_region_highlight=(
"1 8 fg=white,bold,bg=red" # rm -rf /
)
```
Memos and commas
----------------
We append to `region_highlight` as follows:
```zsh
region_highlight+=("$start $end $spec, memo=zsh-syntax-highlighting")
```
That comma is required to cause zsh 5.8 and older to ignore the memo without
ignoring the `$spec`. It's a hack, but given that no further 5.8.x patch
releases are planned, it's been deemed acceptable. See issue #418 and the
cross-referenced issues.
Miscellany
----------
If you work on the driver (`zsh-syntax-highlighting.zsh`), you may find the following zstyle useful:
```zsh
zstyle ':completion:*:*:*:*:globbed-files' ignored-patterns {'*/',}zsh-syntax-highlighting.plugin.zsh
```

### In your ~/.zshrc
Simply clone this repository and source the script:
```zsh
git clone https://github.com/zsh-users/zsh-syntax-highlighting.git
echo "source ${(q-)PWD}/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh" >> ${ZDOTDIR:-$HOME}/.zshrc
```
Then, enable syntax highlighting in the current interactive shell:
```zsh
source ./zsh-syntax-highlighting/zsh-syntax-highlighting.zsh
```
If `git` is not installed, download and extract a snapshot of the latest
development tree from:
```
https://github.com/zsh-users/zsh-syntax-highlighting/archive/master.tar.gz
```
Note the `source` command must be **at the end** of `~/.zshrc`.
### With a plugin manager
Note that `zsh-syntax-highlighting` must be the last plugin sourced.
The zsh-syntax-highlighting authors recommend manual installation over the use
of a framework or plugin manager.
This list is incomplete as there are too many
[frameworks / plugin managers][framework-list] to list them all here.
[framework-list]: https://github.com/unixorn/awesome-zsh-plugins#frameworks
#### [Antigen](https://github.com/zsh-users/antigen)
Add `antigen bundle zsh-users/zsh-syntax-highlighting` as the last bundle in

zsh-syntax-highlighting [![Build Status][build-status-image]][build-status]
=======================
**[Fish shell][fish]-like syntax highlighting for [Zsh][zsh].**
*Requirements: zsh 4.3.11+.*
[fish]: https://fishshell.com/
[zsh]: https://www.zsh.org/
This package provides syntax highlighting for the shell zsh. It enables
highlighting of commands whilst they are typed at a zsh prompt into an
interactive terminal. This helps in reviewing commands before running
them, particularly in catching syntax errors.
Some examples:

How to install

FAQ
---
### Why must `zsh-syntax-highlighting.zsh` be sourced at the end of the `.zshrc` file?
zsh-syntax-highlighting works by hooking into the Zsh Line Editor (ZLE) and
computing syntax highlighting for the command-line buffer as it stands at the
time z-sy-h's hook is invoked.
In zsh 5.2 and older,
`zsh-syntax-highlighting.zsh` hooks into ZLE by wrapping ZLE widgets. It must
be sourced after all custom widgets have been created (i.e., after all `zle -N`
calls and after running `compinit`) in order to be able to wrap all of them.
Widgets created after z-sy-h is sourced will work, but will not update the
syntax highlighting.
In zsh newer than 5.8 (not including 5.8 itself),
zsh-syntax-highlighting uses the `add-zle-hook-widget` facility to install
a `zle-line-pre-redraw` hook. Hooks are run in order of registration,
therefore, z-sy-h must be sourced (and register its hook) after anything else
that adds hooks that modify the command-line buffer.
### Does syntax highlighting work during incremental history search?
Highlighting the command line during an incremental history search (by default bound to
to <kbd>Ctrl+R</kbd> in zsh's emacs keymap) requires zsh 5.4 or newer.
Under zsh versions older than 5.4, the zsh-default [underlining][zshzle-Character-Highlighting]
of the matched portion of the buffer remains available, but zsh-syntax-highlighting's
additional highlighting is unavailable. (Those versions of zsh do not provide
enough information to allow computing the highlighting correctly.)
See issues [#288][i288] and [#415][i415] for details.
[zshzle-Character-Highlighting]: https://zsh.sourceforge.io/Doc/Release/Zsh-Line-Editor.html#Character-Highlighting
[i288]: https://github.com/zsh-users/zsh-syntax-highlighting/pull/288
[i415]: https://github.com/zsh-users/zsh-syntax-highlighting/pull/415
### How are new releases announced?
There is currently no "push" announcements channel. However, the following
alternatives exist:
- GitHub's RSS feed of releases: https://github.com/zsh-users/zsh-syntax-highlighting/releases.atom
- An anitya entry: https://release-monitoring.org/project/7552/
How to tweak
------------
Syntax highlighting is done by pluggable highlighter scripts. See the
[documentation on highlighters](docs/highlighters.md) for details and
configuration settings.

# Changes in HEAD
## Changes fixed as part of the switch to zle-line-pre-redraw
The changes in this section were fixed by switching to a `zle-line-pre-redraw`-based
implementation.
Note: The new implementation will only be used on future zsh releases,
numbered 5.8.1.1 and newer, due to interoperability issues with other plugins
(issues #418 and #579). The underlying zsh feature has been available since
zsh 5.3.
Whilst under development, the new implementation was known as the
"feature/redrawhook" topic branch.
- Fixed: Highlighting not triggered after popping a buffer from the buffer stack
(using the `push-line` widget, default binding: `M-q`)
[#40]
- Fixed: Invoking completion when there were no matches removed highlighting
[#90, #470]
- Fixed: Two successive deletes followed by a yank only yanked the latest
delete, rather than both of them
[#150, #151, #160; cf. #183]
- Presumed fixed: Completing `$(xsel)` results in an error message from `xsel`,
with pre-2017 versions of `xsel`. (For 2017 vintage and newer, see the issue
for details.)
[#154]
- Fixed: When the standard `bracketed-paste-magic` widget is in use, pastes were slow
[#295]
- Fixed: No way to prevent a widget from being wrapped
[#324]
- Fixed: No highlighting while cycling menu completion
[#375]
- Fixed: Does not coexist with the `IGNORE_EOF` option
[#377]
- Fixed: The `undefined-key` widget was wrapped
[#421]
- Fixed: Does not coexist with the standard `surround` family of widgets
[#520]
- Fixed: First completed filename doesn't get `path` highlighting
[#632]
## Other changes
- Add issue #712 to the previous release's changelog (hereinafter).
# Changes in 0.8.0-alpha1-pre-redrawhook
## Notice about an improbable-but-not-impossible forward incompatibility
Everyone can probably skip this section.
The `master` branch of zsh-syntax-highlighting uses a zsh feature that has not
yet appeared in a zsh release: the `memo=` feature, added to zsh in commit
zsh-5.8-172-gdd6e702ee (after zsh 5.8, before zsh 5.9). In the unlikely event
that this zsh feature should change in an incompatible way before the next
stable zsh release, set `zsh_highlight__memo_feature=0` in your .zshrc files to
disable use of the new feature.
z-sy-h dogfoods the new, unreleased zsh feature because that feature was
added to zsh at z-sy-h's initiative. The new feature is used in the fix
to issue #418.
## Incompatible changes:
- An unsuccessful completion (a <kbd>⮀ Tab</kbd> press that doesn't change the
command line) no longer causes highlighting to be lost. Visual feedback can
alternatively be achieved by setting the `format` zstyle under the `warnings`
tag, for example,
zstyle ':completion:*:warnings' format '%F{red}No matches%f'
Refer to the [description of the `format` style in `zshcompsys(1)`]
[zshcompsys-Standard-Styles-format].
(#90, part of #245 (feature/redrawhook))
[zshcompsys-Standard-Styles]: https://zsh.sourceforge.io/Doc/Release/Completion-System.html#Standard-Styles
[zshcompsys-Standard-Styles-format]: https://zsh.sourceforge.io/Doc/Release/Completion-System.html#index-format_002c-completion-style
## Other changes:
- Document `$ZSH_HIGHLIGHT_MAXLENGTH`.
[#698]
- Optimize highlighting unquoted words (words that are not in single quotes, double quotes, backticks, or dollar-single-quotes)
[#730]
- Redirection operators (e.g., `<` and `>`) are now highlighted by default
[#646]
- Propertly terminate `noglob` scope in try/always blocks
[#577]
- Don't error out when `KSH_ARRAYS` is set in the calling scope
[#622, #689]
- Literal semicolons in array assignments (`foo=( bar ; baz )`) are now
highlighted as errors.
[3ca93f864fb6]
- Command separators in array assignments (`foo=( bar | baz )`) are now
highlighted as errors.
[#651, 81267ca3130c]
- Support parameter elision in command position (e.g., `$foo ls` where `$foo` is unset or empty)
[#667]
- Don't consider the filename in `sudo -e /path/to/file` to be a command position
[#678]
- Don't look up absolute directory names in $cdpath
[2cc2583f8f12, part of #669]
- Fix `exec 2>&1;` being highlighted as an error.
[#676]
- Fix `: $(<*)` being highlighted as globbing.
[#582]
- Fix `cat < *` being highlighting as globbing when the `MULTIOS` option is unset.
[#583]
- Fix `echo >&2` highlighting the `2` as a filename if a file by that name happened to exist
[#694, part of #645]
- Fix `echo >&-` highlighting the `-` as a filename if a file by that name happened to exist
[part of #645]
- Fix `echo >&p` highlighting the `p` as a filename if a file by that name happened to exist
[part of #645]
- Fix wrong highlighting of unquoted parameter expansions under zsh 5.2 and older

`_zsh_highlight_main__precmd_hook:1: array parameter _zsh_highlight_main__command_type_cache set in enclosing scope in function _zsh_highlight_main__precmd_hook`
[#727, #731, #732, #733]
- Fix highlighting of alias whose definitions use a simple command terminator
(such as `;`, `|`, `&&`) before a newline
[#677; had regressed in 0.7.0]
- Highlight arithmetic expansions (e.g., `$(( 42 ))`)
[#607 #649 #704]
- Highlight the parentheses of array assignments as reserved words (`foo=( bar )`).
The `assign` style remains supported and has precedence.

requires zsh 5.8.0.3 or newer. (zsh 5.8.0.2-dev from the `master` branch,
revision zsh-5.8-172-gdd6e702ee or newer is also fine.)
[#418, https://github.com/okapia/zsh-viexchange/issues/1]
- Improve performance of the `brackets` highlighter.
- Fix highlighting of pre-command redirections (e.g., the `$fn` in `<$fn cat`)

- Aliases that cannot be defined normally nor invoked normally (highlighted as an error).
(#263 (in part), 28932316cca6)
- Path separators (`/`) — the default behaviour remains to highlight path separators
and path components the same way.

(#267, a7a7f8b42280, ee07588cfd9b)
- Command-lines recalled by `isearch` mode; requires zsh≥5.3.
(#261 (in part); #257; 4ad311ec0a68)
- Command-lines whilst the `IGNORE_BRACES` or `IGNORE_CLOSE_BRACES` option is in effect.
(a8a6384356af, 02807f1826a5)
- Mismatched parentheses and braces (in the `main` highlighter).
(51b9d79c3bb6, 2fabf7ca64b7, a4196eda5e6f, and others)
- Mismatched `do`/`done` keywords.
(b2733a64da93)
- Mismatched `foreach`/`end` keywords.
(#96, 2bb8f0703d8f)
- In Bourne-style function definitions, when the `MULTI_FUNC_DEF` option is set
(which is the default), highlight the first word in the function body as
a command word: `f() { g "$@" }`.
(6f91850a01e1)

- Command substitutions inside double quotes, `"$(echo foo)"`.
(#139 (in part), c3913e0d8ead)

(4afe670f7a1b, 44ef6e38e5a7)
- Command words from future versions of zsh (forward compatibly).
This also adds an `arg0` style that all other command word styles fall back to.

- Escaped history expansions inside double quotes: `: "\!"`
(28d7056a7a06, et seq)
## Fixed highlighting of:
- Command separator tokens in syntactically-invalid positions.
(09c4114eb980)
- Redirections with a file descriptor number at command word.
(#238 (in part), 73ee7c1f6c4a)
- The `select` prompt, `$PS3`.
(#268, 451665cb2a8b)
- Values of variables in `vared`.
(e500ca246286)
- `!` as an argument (neither a history expansion nor a reserved word).
(4c23a2fd1b90)
- "division by zero" error under the `brackets` highlighter when `$ZSH_HIGHLIGHT_STYLES` is empty.
(f73f3d53d3a6)
- Process substitutions, `<(pwd)` and `>(wc -l)`.
(#302, 6889ff6bd2ad, bfabffbf975c, fc9c892a3f15)
- The non-`SHORT_LOOPS` form of `repeat` loops: `repeat 42; do true; done`.
(#290, 4832f18c50a5, ef68f50c048f, 6362c757b6f7)

- Lines accepted from `isearch` mode.
(#284; #257, #259, #288; 5bae6219008b, a8fe22d42251)
- Work around upstream bug that triggered when the command word was a relative
path, that when interpreted relative to a $PATH directory denoted a command;
the effect of that upstream bug was that the relative path was cached as
a "valid external command name".
(#354, #355, 51614ca2c994, fdaeec45146b, 7d38d07255e4;
upstream fix slated to be released in 5.3 (workers/39104))
- After accepting a line with the cursor on a bracket, the matching bracket
of the bracket under the cursor no longer remains highlighted (with the
`brackets` highlighter).
(4c4baede519a)
- The first word on a new line within an array assignment or initialization is no
longer considered a command position.
(8bf423d16d46)

(#231, 7fb6f9979121; #344, 4fc35362ee5a)
- Command word after array assignment, `a=(lorem ipsum) pwd`.
(#330, 7fb6f9979121)
## API changes (for highlighter authors):
- New interface `_zsh_highlight_add_highlight`.
(341a3ae1f015, c346f6eb6fb6)
- tests: Specify the style key, not its value, in test expectations.

zsh-syntax-highlighting / highlighters
======================================
Syntax highlighting is done by pluggable highlighters:
* `main` - the base highlighter, and the only one [active by default][main].
* `brackets` - [matches brackets][brackets] and parenthesis.
* `pattern` - matches [user-defined patterns][pattern].
* `regexp` - matches [user-defined regular expressions][regexp].
* `cursor` - matches [the cursor position][cursor].
* `root` - highlights the whole command line [if the current user is root][root].
* `line` - applied to [the whole command line][line].
[main]: highlighters/main.md
[brackets]: highlighters/brackets.md
[pattern]: highlighters/pattern.md
[regexp]: highlighters/regexp.md
[cursor]: highlighters/cursor.md
[root]: highlighters/root.md
[line]: highlighters/line.md
Highlighter-independent settings
--------------------------------
By default, all command lines are highlighted. However, it is possible to
prevent command lines longer than a fixed number of characters from being
highlighted by setting the variable `${ZSH_HIGHLIGHT_MAXLENGTH}` to the maximum
length (in characters) of command lines to be highlighter. This is useful when
editing very long command lines (for example, with the [`fned`][fned] utility
function). Example:
[fned]: https://zsh.sourceforge.io/Doc/Release/User-Contributions.html#index-zed
```zsh
ZSH_HIGHLIGHT_MAXLENGTH=512
```
How to activate highlighters
----------------------------
To activate an highlighter, add it to the `ZSH_HIGHLIGHT_HIGHLIGHTERS` array in
`~/.zshrc`, for example:
```zsh
ZSH_HIGHLIGHT_HIGHLIGHTERS=(main brackets pattern cursor)
```
By default, `$ZSH_HIGHLIGHT_HIGHLIGHTERS` is unset and only the `main`
highlighter is active.
How to tweak highlighters
-------------------------
Highlighters look up styles from the `ZSH_HIGHLIGHT_STYLES` associative array.
Navigate into the [individual highlighters' documentation](highlighters/) to
see what styles (keys) each highlighter defines; the syntax for values is the
same as the syntax of "types of highlighting" of the zsh builtin
`$zle_highlight` array, which is documented in [the `zshzle(1)` manual
page][zshzle-Character-Highlighting].
[zshzle-Character-Highlighting]: https://zsh.sourceforge.io/Doc/Release/Zsh-Line-Editor.html#Character-Highlighting
Some highlighters support additional configuration parameters; see each
highlighter's documentation for details and examples.
How to implement a new highlighter
----------------------------------
To create your own `acme` highlighter:
* Create your script at
`highlighters/acme/acme-highlighter.zsh`.
* Implement the `_zsh_highlight_highlighter_acme_predicate` function.
This function must return 0 when the highlighter needs to be called and
non-zero otherwise, for example:
```zsh
_zsh_highlight_highlighter_acme_predicate() {
# Call this highlighter in SVN working copies
[[ -d .svn ]]
}
```
* Implement the `_zsh_highlight_highlighter_acme_paint` function.
This function does the actual syntax highlighting, by calling
`_zsh_highlight_add_highlight` with the start and end of the region to
be highlighted and the `ZSH_HIGHLIGHT_STYLES` key to use. Define the default
style for that key in the highlighter script outside of any function with
`: ${ZSH_HIGHLIGHT_STYLES[key]:=value}`, being sure to prefix
the key with your highlighter name and a colon. For example:
```zsh
: ${ZSH_HIGHLIGHT_STYLES[acme:aurora]:=fg=green}
_zsh_highlight_highlighter_acme_paint() {
# Colorize the whole buffer with the 'aurora' style
_zsh_highlight_add_highlight 0 $#BUFFER acme:aurora
}
```
If you need to test which options the user has set, test `zsyh_user_options`
with a sensible default if the option is not present in supported zsh
versions. For example:
```zsh
[[ ${zsyh_user_options[ignoreclosebraces]:-off} == on ]]
```
The option name must be all lowercase with no underscores and not an alias.
* Name your own functions and global variables `_zsh_highlight_acme_*`.
- In zsh-syntax-highlighting 0.4.0 and earlier, the entrypoints
`_zsh_highlight_highlighter_acme_predicate` and
`_zsh_highlight_highlighter_acme_paint`
were named
`_zsh_highlight_acme_highlighter_predicate` and
`_zsh_highlight_highlighter_acme_paint` respectively.
These names are still supported for backwards compatibility;
however, support for them will be removed in a future major or minor release (v0.x.0 or v1.0.0).
* Activate your highlighter in `~/.zshrc`:
```zsh
ZSH_HIGHLIGHT_HIGHLIGHTERS+=(acme)
```
* [Write tests](../tests/README.md).

zsh-syntax-highlighting / highlighters / brackets
-------------------------------------------------
This is the `brackets` highlighter, that highlights brackets and parentheses, and
matches them.
### How to tweak it
This highlighter defines the following styles:
* `bracket-error` - unmatched brackets
* `bracket-level-N` - brackets with nest level N
* `cursor-matchingbracket` - the matching bracket, if cursor is on a bracket
To override one of those styles, change its entry in `ZSH_HIGHLIGHT_STYLES`,
for example in `~/.zshrc`:
```zsh
# To define styles for nested brackets up to level 4
ZSH_HIGHLIGHT_STYLES[bracket-level-1]='fg=blue,bold'
ZSH_HIGHLIGHT_STYLES[bracket-level-2]='fg=red,bold'
ZSH_HIGHLIGHT_STYLES[bracket-level-3]='fg=yellow,bold'
ZSH_HIGHLIGHT_STYLES[bracket-level-4]='fg=magenta,bold'
```
The syntax for values is the same as the syntax of "types of highlighting" of
the zsh builtin `$zle_highlight` array, which is documented in [the `zshzle(1)`
manual page][zshzle-Character-Highlighting].

ZSH_HIGHLIGHT_STYLES[alias]='fg=magenta,bold'
# To have paths colored instead of underlined
ZSH_HIGHLIGHT_STYLES[path]='fg=cyan'
# To disable highlighting of globbing expressions
ZSH_HIGHLIGHT_STYLES[globbing]='none'
```
The syntax for values is the same as the syntax of "types of highlighting" of
the zsh builtin `$zle_highlight` array, which is documented in [the `zshzle(1)`
manual page][zshzle-Character-Highlighting].
#### Parameters
To avoid partial path lookups on a path, add the path to the `ZSH_HIGHLIGHT_DIRS_BLACKLIST` array.
```zsh
ZSH_HIGHLIGHT_DIRS_BLACKLIST+=(/mnt/slow_share)
```
### Useless trivia
#### Forward compatibility.
zsh-syntax-highlighting attempts to be forward-compatible with zsh.
Specifically, we attempt to facilitate highlighting _command word_ types that
had not yet been invented when this version of zsh-syntax-highlighting was
released.
A _command word_ is something like a function name, external command name, et
cetera. (See
[Simple Commands & Pipelines in `zshmisc(1)`][zshmisc-Simple-Commands-And-Pipelines]
for a formal definition.)
If a new _kind_ of command word is ever added to zsh — something conceptually
different than "function" and "alias" and "external command" — then command words
of that (new) kind will be highlighted by the style `arg0_$kind`,
where `$kind` is the output of `type -w` on the new kind of command word. If that
style is not defined, then the style `arg0` will be used instead.

zsh-syntax-highlighting / highlighters / regexp
------------------------------------------------
This is the `regexp` highlighter, that highlights user-defined regular
expressions. It's similar to the `pattern` highlighter, but allows more complex
patterns.
### How to tweak it
To use this highlighter, associate regular expressions with styles in the
`ZSH_HIGHLIGHT_REGEXP` associative array, for example in `~/.zshrc`:
```zsh
typeset -A ZSH_HIGHLIGHT_REGEXP
ZSH_HIGHLIGHT_REGEXP+=('^rm .*' fg=red,bold)
```
This will highlight lines that start with a call to the `rm` command.
The regular expressions flavour used is [PCRE][pcresyntax] when the
`RE_MATCH_PCRE` option is set and POSIX Extended Regular Expressions (ERE),
as implemented by the platform's C library, otherwise. For details on the
latter, see [the `zsh/regex` module's documentation][MAN_ZSH_REGEX] and the
`regcomp(3)` and `re_format(7)` manual pages on your system.
For instance, to highlight `sudo` only as a complete word, i.e., `sudo cmd`,
but not `sudoedit`, one might use:
* When the `RE_MATCH_PCRE` is set:
```zsh
typeset -A ZSH_HIGHLIGHT_REGEXP
ZSH_HIGHLIGHT_REGEXP+=('\bsudo\b' fg=123,bold)
```
* When the `RE_MATCH_PCRE` is unset, on platforms with GNU `libc` (e.g., many GNU/Linux distributions):
```zsh
typeset -A ZSH_HIGHLIGHT_REGEXP
ZSH_HIGHLIGHT_REGEXP+=('\<sudo\>' fg=123,bold)
```
* When the `RE_MATCH_PCRE` is unset, on BSD-based platforms (e.g., macOS):
```zsh
typeset -A ZSH_HIGHLIGHT_REGEXP
ZSH_HIGHLIGHT_REGEXP+=('[[:<:]]sudo[[:>:]]' fg=123,bold)
```
Note, however, that PCRE and POSIX ERE have a large common subset:
for instance, the regular expressions `[abc]`, `a*`, and `(a|b)` have the same
meaning in both flavours.
The syntax for values is the same as the syntax of "types of highlighting" of
the zsh builtin `$zle_highlight` array, which is documented in [the `zshzle(1)`
manual page][zshzle-Character-Highlighting].

zsh-syntax-highlighting / highlighters / root
---------------------------------------------
This is the `root` highlighter, that highlights the whole line if the current
user is root.
### How to tweak it
This highlighter defines the following styles:
* `root` - the style for the whole line if the current user is root.
To override one of those styles, change its entry in `ZSH_HIGHLIGHT_STYLES`,
for example in `~/.zshrc`:
```zsh
ZSH_HIGHLIGHT_STYLES[root]='bg=red'
```
The syntax for values is the same as the syntax of "types of highlighting" of
the zsh builtin `$zle_highlight` array, which is documented in [the `zshzle(1)`
manual page][zshzle-Character-Highlighting].
