# Contributor Covenant Code of Conduct
## Our Pledge
In the interest of fostering an open and welcoming environment, we as
contributors and maintainers pledge to making participation in our project and
our community a harassment-free experience for everyone, regardless of age, body
size, disability, ethnicity, sex characteristics, gender identity and expression,
level of experience, education, socio-economic status, nationality, personal
appearance, race, religion, or sexual identity and orientation.
## Our Standards
Examples of behavior that contributes to creating a positive environment
include:
* Using welcoming and inclusive language
* Being respectful of differing viewpoints and experiences
* Gracefully accepting constructive criticism
* Focusing on what is best for the community
* Showing empathy towards other community members
Examples of unacceptable behavior by participants include:
* The use of sexualized language or imagery and unwelcome sexual attention or
advances
* Trolling, insulting/derogatory comments, and personal or political attacks
* Public or private harassment
* Publishing others' private information, such as a physical or electronic
address, without explicit permission
* Other conduct which could reasonably be considered inappropriate in a
professional setting
## Our Responsibilities

## Reporting Issues
### You have a problem
Please be so kind as to [search](#use-the-search-luke) for any open issue already covering
your problem.
If you find one, comment on it so we can know there are more people experiencing it.
If not, look at the [Troubleshooting](https://github.com/ohmyzsh/ohmyzsh/wiki/Troubleshooting)
page for instructions on how to gather data to better debug your problem.
Then, you can go ahead and create an issue with as much detail as you can provide.
It should include the data gathered as indicated above, along with:
1. How to reproduce the problem
2. What the correct behavior should be
3. What the actual behavior is
Please copy to anyone relevant (_eg_ plugin maintainers) by mentioning their GitHub handle
(starting with `@`) in your message.
We will do our very best to help you.
### You have a suggestion
Please be so kind as to [search](#use-the-search-luke) for any open issue already covering
your suggestion.
If you find one, comment on it so we can know there are more people supporting it.
If not, you can go ahead and create an issue. Please copy to anyone relevant (_eg_ plugin
maintainers) by mentioning their GitHub handle (starting with `@`) in your message.
## Submitting Pull Requests
### Getting started
You should be familiar with the basics of
[contributing on GitHub](https://help.github.com/articles/using-pull-requests) and have a fork
[properly set up](https://github.com/ohmyzsh/ohmyzsh/wiki/Contribution-Technical-Practices).
You MUST always create PRs with _a dedicated branch_ based on the latest upstream tree.
If you create your own PR, please make sure you do it right. Also be so kind as to reference
any issue that would be solved in the PR description body,
[for instance](https://help.github.com/articles/closing-issues-via-commit-messages/)
_"Fixes #XXXX"_ for issue number XXXX.
### You have a solution
Please be so kind as to [search](#use-the-search-luke) for any open issue already covering
your [problem](#you-have-a-problem), and any pending/merged/rejected PR covering your solution.
If the solution is already reported, try it out and +1 the pull request if the
solution works ok. On the other hand, if you think your solution is better, post
it with a reference to the other one so we can have both solutions to compare.
If not, then go ahead and submit a PR. Please copy to anyone relevant (e.g. plugin
maintainers) by mentioning their GitHub handle (starting with `@`) in your message.
### You have an addition
Please [do not](https://github.com/ohmyzsh/ohmyzsh/wiki/Themes#dont-send-us-your-theme-for-now)
send themes for now.
Please be so kind as to [search](#use-the-search-luke) for any pending, merged or rejected Pull Requests
covering or related to what you want to add.
If you find one, try it out and work with the author on a common solution.
If not, then go ahead and submit a PR. Please copy to anyone relevant (_eg_ plugin
maintainers) by mentioning their GitHub handle (starting with `@`) in your message.
For any extensive change, _eg_ a new plugin, you will have to find testers to +1 your PR.
----
## Use the Search, Luke
_May the Force (of past experiences) be with you_
GitHub offers [many search features](https://help.github.com/articles/searching-github/)
to help you check whether a similar contribution to yours already exists. Please search
before making any contribution, it avoids duplicates and eases maintenance. Trust me,
that works 90% of the time.
You can also take a look at the [FAQ](https://github.com/ohmyzsh/ohmyzsh/wiki/FAQ)
to be sure your contribution has not already come up.
If all fails, your thing has probably not been reported yet, so you can go ahead
and [create an issue](#reporting-issues) or [submit a PR](#submitting-pull-requests).
----
### You have spare time to volunteer
Very nice!! :)
Please have a look at the [Volunteer](https://github.com/ohmyzsh/ohmyzsh/wiki/Volunteers)
page for instructions on where to start and more.

Oh My Zsh is an open source, community-driven framework for managing your [zsh](https://www.zsh.org/) configuration.
Sounds boring. Let's try again.
__Oh My Zsh will not make you a 10x developer...but you may feel like one.__
Once installed, your terminal shell will become the talk of the town _or your money back!_ With each keystroke in your command prompt, you'll take advantage of the hundreds of powerful plugins and beautiful themes. Strangers will come up to you in cafés and ask you, _"that is amazing! are you some sort of genius?"_
Finally, you'll begin to get the sort of attention that you have always felt you deserved. ...or maybe you'll use the time that you're saving to start flossing more often. 😬
To learn more, visit [ohmyz.sh](https://ohmyz.sh), follow [@ohmyzsh](https://twitter.com/ohmyzsh) on Twitter, and/or join us on [Discord](https://discord.gg/ohmyzsh).

## Getting Started
### Prerequisites
* A Unix-like operating system: macOS, Linux, BSD. On Windows: WSL2 is preferred, but cygwin or msys also mostly work.
* [Zsh](https://www.zsh.org) should be installed (v4.3.9 or more recent is fine but we prefer 5.0.8 and newer). If not pre-installed (run `zsh --version` to confirm), check the following wiki instructions here: [Installing ZSH](https://github.com/ohmyzsh/ohmyzsh/wiki/Installing-ZSH)
* `curl` or `wget` should be installed
* `git` should be installed (recommended v2.4.11 or higher)
### Basic Installation
Oh My Zsh is installed by running one of the following commands in your terminal. You can install this via the command-line with either `curl` or `wget`, whichever is installed on your machine.
#### via curl
```shell
sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
```
#### via wget
```shell
sh -c "$(wget -O- https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
```
#### via fetch
```shell
sh -c "$(fetch -o - https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
```
#### Manual inspection
It's a good idea to inspect the install script from projects you don't yet know. You can do
that by downloading the install script first, looking through it so everything looks normal,
then running it:
```shell
curl -Lo install.sh https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh
sh install.sh
```
## Using Oh My Zsh
### Plugins
Oh My Zsh comes with a shitload of plugins for you to take advantage of. You can take a look in the [plugins](https://github.com/ohmyzsh/ohmyzsh/tree/master/plugins) directory and/or the [wiki](https://github.com/ohmyzsh/ohmyzsh/wiki/Plugins) to see what's currently available.
#### Enabling Plugins
Once you spot a plugin (or several) that you'd like to use with Oh My Zsh, you'll need to enable them in the `.zshrc` file. You'll find the zshrc file in your `$HOME` directory. Open it with your favorite text editor and you'll see a spot to list all the plugins you want to load.
```shell
vi ~/.zshrc
```
For example, this might begin to look like this:
```shell
plugins=(
git
bundler
dotenv
osx
rake
rbenv
ruby
)
```
_Note that the plugins are separated by whitespace (spaces, tabs, new lines...). **Do not** use commas between them or it will break._
#### Using Plugins
Each plugin includes a __README__, documenting it. This README should show the aliases (if the plugin adds any) and extra goodies that are inclued in that particular plugin.
### Themes
We'll admit it. Early in the Oh My Zsh world, we may have gotten a bit too theme happy. We have over one hundred and fifty themes now bundled. Most of them have [screenshots](https://github.com/ohmyzsh/ohmyzsh/wiki/Themes) on the wiki (We are working on updating this!). Check them out!
#### Selecting a Theme
_Robby's theme is the default one. It's not the fanciest one. It's not the simplest one. It's just the right one (for him)._
Once you find a theme that you'd like to use, you will need to edit the `~/.zshrc` file. You'll see an environment variable (all caps) in there that looks like:
```shell
ZSH_THEME="robbyrussell"
```
To use a different theme, simply change the value to match the name of your desired theme. For example:
```shell
ZSH_THEME="agnoster" # (this is one of the fancy ones)
# see https://github.com/ohmyzsh/ohmyzsh/wiki/Themes#agnoster
```
_Note: many themes require installing the [Powerline Fonts](https://github.com/powerline/fonts) in order to render properly._
Open up a new terminal window and your prompt should look something like this:
![Agnoster theme](https://cloud.githubusercontent.com/assets/2618447/6316862/70f58fb6-ba03-11e4-82c9-c083bf9a6574.png)
In case you did not find a suitable theme for your needs, please have a look at the wiki for [more of them](https://github.com/ohmyzsh/ohmyzsh/wiki/External-themes).
If you're feeling feisty, you can let the computer select one randomly for you each time you open a new terminal window.
```shell
ZSH_THEME="random" # (...please let it be pie... please be some pie..)
```
And if you want to pick random theme from a list of your favorite themes:
```shell
ZSH_THEME_RANDOM_CANDIDATES=(
"robbyrussell"
"agnoster"
)
```
If you only know which themes you don't like, you can add them similarly to a blacklist:
```shell
ZSH_THEME_RANDOM_BLACKLIST=(pygmalion tjkirch_mod)
```
### FAQ
If you have some more questions or issues, you might find a solution in our [FAQ](https://github.com/ohmyzsh/ohmyzsh/wiki/FAQ).
## Advanced Topics
If you're the type that likes to get their hands dirty, these sections might resonate.
### Advanced Installation
Some users may want to manually install Oh My Zsh, or change the default path or other settings that
the installer accepts (these settings are also documented at the top of the install script).
#### Custom Directory
The default location is `~/.oh-my-zsh` (hidden in your home directory, you can access it with `cd ~/.oh-my-zsh`)
If you'd like to change the install directory with the `ZSH` environment variable, either by running
`export ZSH=/your/path` before installing, or by setting it before the end of the install pipeline
like this:
```shell
ZSH="$HOME/.dotfiles/oh-my-zsh" sh install.sh
```
#### Unattended install
If you're running the Oh My Zsh install script as part of an automated install, you can pass the
flag `--unattended` to the `install.sh` script. This will have the effect of not trying to change
the default shell, and also won't run `zsh` when the installation has finished.
```shell
sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)" "" --unattended
```
#### Installing from a forked repository
The install script also accepts these variables to allow installation of a different repository:
- `REPO` (default: `ohmyzsh/ohmyzsh`): this takes the form of `owner/repository`. If you set
this variable, the installer will look for a repository at `https://github.com/{owner}/{repository}`.
- `REMOTE` (default: `https://github.com/${REPO}.git`): this is the full URL of the git repository
clone. You can use this setting if you want to install from a fork that is not on GitHub (GitLab,
Bitbucket...) or if you want to clone with SSH instead of HTTPS (`git@github.com:user/project.git`).
_NOTE: it's incompatible with setting the `REPO` variable. This setting will take precedence._
- `BRANCH` (default: `master`): you can use this setting if you want to change the default branch to be
checked out when cloning the repository. This might be useful for testing a Pull Request, or if you
want to use a branch other than `master`.
For example:
```shell
REPO=apjanke/oh-my-zsh BRANCH=edge sh install.sh
```
#### Manual Installation
##### 1. Clone the repository:
```shell
git clone https://github.com/ohmyzsh/ohmyzsh.git ~/.oh-my-zsh
```
##### 2. *Optionally*, backup your existing `~/.zshrc` file:
```shell
cp ~/.zshrc ~/.zshrc.orig
```
##### 3. Create a new zsh configuration file
You can create a new zsh config file by copying the template that we have included for you.
```shell
cp ~/.oh-my-zsh/templates/zshrc.zsh-template ~/.zshrc
```
##### 4. Change your default shell
```shell
chsh -s $(which zsh)
```
You must log out from your user session and log back in to see this change.
##### 5. Initialize your new zsh configuration
Once you open up a new terminal window, it should load zsh with Oh My Zsh's configuration.
### Installation Problems
If you have any hiccups installing, here are a few common fixes.
* You _might_ need to modify your `PATH` in `~/.zshrc` if you're not able to find some commands after
switching to `oh-my-zsh`.
* If you installed manually or changed the install location, check the `ZSH` environment variable in
`~/.zshrc`.
### Custom Plugins and Themes
If you want to override any of the default behaviors, just add a new file (ending in `.zsh`) in the `custom/` directory.
If you have many functions that go well together, you can put them as a `XYZ.plugin.zsh` file in the `custom/plugins/` directory and then enable this plugin.
If you would like to override the functionality of a plugin distributed with Oh My Zsh, create a plugin of the same name in the `custom/plugins/` directory and it will be loaded instead of the one in `plugins/`.
## Getting Updates
By default, you will be prompted to check for upgrades every few weeks. If you would like `oh-my-zsh` to automatically upgrade itself without prompting you, set the following in your `~/.zshrc`:
```shell
DISABLE_UPDATE_PROMPT=true
```
To disable automatic upgrades, set the following in your `~/.zshrc`:
```shell
DISABLE_AUTO_UPDATE=true
```
### Manual Updates
If you'd like to upgrade at any point in time (maybe someone just released a new plugin and you don't want to wait a week?) you just need to run:
```shell
upgrade_oh_my_zsh
```
Magic! 🎉
## Uninstalling Oh My Zsh
Oh My Zsh isn't for everyone. We'll miss you, but we want to make this an easy breakup.
If you want to uninstall `oh-my-zsh`, just run `uninstall_oh_my_zsh` from the command-line. It will remove itself and revert your previous `bash` or `zsh` configuration.
## How do I contribute to Oh My Zsh?
Before you participate in our delightful community, please read the [code of conduct](CODE_OF_CONDUCT.md).
I'm far from being a [Zsh](https://www.zsh.org/) expert and suspect there are many ways to improve if you have ideas on how to make the configuration easier to maintain (and faster), don't hesitate to fork and send pull requests!
We also need people to test out pull-requests. So take a look through [the open issues](https://github.com/ohmyzsh/ohmyzsh/issues) and help where you can.
See [Contributing](CONTRIBUTING.md) for more details.
### Do NOT send us themes
We have (more than) enough themes for the time being. Please add your theme to the [external themes](https://github.com/ohmyzsh/ohmyzsh/wiki/External-themes) wiki page.

### Describe the bug
<!-- A clear and concise description of what the bug is. -->
### To Reproduce
Steps to reproduce the behavior:
<!-- If you are not able to reproduce it by running `zsh -df` and sourcing the plugin manually, it means there that the issue is caused by something in your local config file(s). Temporarily comment out or remove sections of your config and restart `zsh` until you narrow down exactly what is causing the issue. -->

# 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
[![CircleCI](https://img.shields.io/circleci/build/github/zsh-users/zsh-autosuggestions.svg)](https://circleci.com/gh/zsh-users/zsh-autosuggestions)
[![Chat on Gitter](https://img.shields.io/gitter/room/zsh-users/zsh-autosuggestions.svg)](https://gitter.im/zsh-users/zsh-autosuggestions)
<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.
### Enable Asynchronous Mode
As of `v0.4.0`, suggestions can be fetched asynchronously. To enable this behavior, set the `ZSH_AUTOSUGGEST_USE_ASYNC` variable (it can be set to anything).
### 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 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 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
your `.zshrc`.
#### [Oh-my-zsh](https://github.com/robbyrussell/oh-my-zsh)
1. Clone this repository in oh-my-zsh's plugins directory:
```zsh
git clone https://github.com/zsh-users/zsh-syntax-highlighting.git ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-syntax-highlighting
```
2. Activate the plugin in `~/.zshrc`:
```zsh
plugins=( [plugins...] zsh-syntax-highlighting)
```
3. Restart zsh (such as by opening a new instance of your terminal emulator).
#### [Prezto](https://github.com/sorin-ionescu/prezto)
Zsh-syntax-highlighting is included with Prezto. See the
[Prezto documentation][prezto-docs] to enable and configure highlighters.
[prezto-docs]: https://github.com/sorin-ionescu/prezto/tree/master/modules/syntax-highlighting
#### [zgen](https://github.com/tarjoilija/zgen)
Add `zgen load zsh-users/zsh-syntax-highlighting` to the end of your `.zshrc`.
#### [zplug](https://github.com/zplug/zplug)
Add `zplug "zsh-users/zsh-syntax-highlighting", defer:2` to your `.zshrc`.
#### [zplugin](https://github.com/psprint/zplugin)
Add `zplugin load zsh-users/zsh-syntax-highlighting` to the end of your
`.zshrc`.
### System-wide installation
Any of the above methods is suitable for a single-user installation,
which requires no special privileges. If, however, you desire to install
zsh-syntax-highlighting system-wide, you may do so by running
```zsh
make install
```
and directing your users to add
```zsh
source /usr/local/share/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh
```
to their `.zshrc`s.

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]: http://www.fishshell.com/
[zsh]: http://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.

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.

[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 5.8.0.3 and newer, due to interoperability issues with other plugins
(issues #418 and #579). The underlying zsh feature has been available since
zsh 5.2.
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-format]: http://zsh.sourceforge.net/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 `: $(<*)` being highlighted as globbing.
[#582]
- Fix `cat < *` being highlighting as globbing when the `MULTIOS` option is unset.
[#583]
- Fix `echo >&2` highlighting the `2` as a filename if a file by that name happened to exist
[#694, part of #645]
- Fix `echo >&-` highlighting the `-` as a filename if a file by that name happened to exist
[part of #645]
- Fix `echo >&p` highlighting the `p` as a filename if a file by that name happened to exist
[part of #645]
- Fix wrong highlighting of unquoted parameter expansions under zsh 5.2 and older
[e165f18c758e]
- Highlight global aliases
[#700]
- Highlight `: =nosuchcommand' as an error (when the `EQUALS` option hasn't been unset).
[#430]
- Highlight reserved word after assignments as errors (e.g., `foo=bar (ls;)`)
[#461]
- Correctly highlight `[[ foo && bar || baz ]]`.
- Highlight non-executable files in command position correctly (e.g., `% /etc/passwd`)
[#202, #669]
- Highlight directories in command position correctly, including `AUTO_CD` support
[#669]
- Recognize `env` as a precommand (e.g., `env FOO=bar ls`)
- Recognize `strace` as a precommand
- Fix an error message on stderr before every prompt when the `WARN_NESTED_VAR` zsh option is set:
`_zsh_highlight_main__precmd_hook:1: array parameter _zsh_highlight_main__command_type_cache set in enclosing scope in function _zsh_highlight_main__precmd_hook`
[#727, #731, #732, #733]
- Fix highlighting of alias whose definitions use a simple command terminator
(such as `;`, `|`, `&&`) before a newline
[#677; had regressed in 0.7.0]
- Highlight arithmetic expansions (e.g., `$(( 42 ))`)
[#607 #649 #704]
- Highlight the parentheses of array assignments as reserved words (`foo=( bar )`).
The `assign` style remains supported and has precedence.
[#585]
- Fix interoperability issue with other plugins that use highlighting. The fix
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`)
[#712]
# Changes in version 0.7.1
- Remove out-of-date information from the 0.7.0 changelog.
# Changes in version 0.7.0
This is a stable bugfix and feature release. Major new features and changes include:
- Add `ZSH_HIGHLIGHT_DIRS_BLACKLIST` to disable "path" and "path prefix"
highlighting for specific directories
[#379]
- Add the "regexp" highlighter, modelled after the pattern highlighter
[4e6f60063f1c]

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".

zsh-syntax-highlighting / highlighters
======================================
Syntax highlighting is done by pluggable highlighters:
* `main` - the base highlighter, and the only one [active by default][1].
* `brackets` - [matches brackets][2] and parenthesis.
* `pattern` - matches [user-defined patterns][3].
* `cursor` - matches [the cursor position][4].
* `root` - highlights the whole command line [if the current user is root][5].
* `line` - applied to [the whole command line][6].
[1]: highlighters/main.md
[2]: highlighters/brackets.md
[3]: highlighters/pattern.md
[4]: highlighters/cursor.md
[5]: highlighters/root.md
[6]: 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 `${ZSH_HIGHLIGHT_MAXLENGTH}` to the maximum
length (in characters) of command lines to be highlighter. This is useful when
editing very long comand lines (for example, with the [`fned`][fned] utility
function). Example:
[fned]: http://zsh.sourceforge.net/Doc/Release/User-Contributions.html#index-zed
```zsh
ZSH_HIGHLIGHT_MAXLENGTH=512
```
How to activate highlighters
----------------------------
To activate an highlighter, add it to the `ZSH_HIGHLIGHT_HIGHLIGHTERS` array in
`~/.zshrc`, for example:
```zsh
ZSH_HIGHLIGHT_HIGHLIGHTERS=(main brackets pattern cursor)
```
By default, `$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]: http://zsh.sourceforge.net/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-syntax-highlighting / highlighters / cursor
-----------------------------------------------
This is the `cursor` highlighter, that highlights the cursor.
### How to tweak it
This highlighter defines the following styles:
* `cursor` - the style for the current cursor position
To override one of those styles, change its entry in `ZSH_HIGHLIGHT_STYLES`,
for example in `~/.zshrc`:
```zsh
ZSH_HIGHLIGHT_STYLES[cursor]='bg=blue'
```
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].

* `double-quoted-argument-unclosed` - unclosed double-quoted arguments (`` "foo ``)
* `dollar-quoted-argument` - dollar-quoted arguments (`` $'foo' ``)
* `dollar-quoted-argument-unclosed` - unclosed dollar-quoted arguments (`` $'foo ``)
* `rc-quote` - two single quotes inside single quotes when the `RC_QUOTES` option is set (`` 'foo''bar' ``)
* `dollar-double-quoted-argument` - parameter expansion inside double quotes (`$foo` inside `""`)
* `back-double-quoted-argument` - backslash escape sequences inside double-quoted arguments (`\"` in `"foo\"bar"`)
* `back-dollar-quoted-argument` - backslash escape sequences inside dollar-quoted arguments (`\x` in `$'\x48'`)
* `assign` - parameter assignments (`x=foo` and `x=( )`)
* `redirection` - redirection operators (`<`, `>`, etc)
* `comment` - comments, when `setopt INTERACTIVE_COMMENTS` is in effect (`echo # foo`)

* `named-fd` - named file descriptor (the `fd` in `echo foo {fd}>&2`)
* `numeric-fd` - numeric file descriptor (the `2` in `echo foo {fd}>&2`)
* `arg0` - a command word other than one of those enumerated above (other than a command, precommand, alias, function, or shell builtin command).
* `default` - everything else
To override one of those styles, change its entry in `ZSH_HIGHLIGHT_STYLES`,
for example in `~/.zshrc`:
```zsh
# Declare the variable
typeset -A ZSH_HIGHLIGHT_STYLES
# To differentiate aliases from other command types
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 / pattern
------------------------------------------------
This is the `pattern` highlighter, that highlights user-defined patterns.
### How to tweak it
To use this highlighter, associate patterns with styles in the
`ZSH_HIGHLIGHT_PATTERNS` associative array, for example in `~/.zshrc`:
```zsh
# Declare the variable
typeset -A ZSH_HIGHLIGHT_PATTERNS
# To have commands starting with `rm -rf` in red:
ZSH_HIGHLIGHT_PATTERNS+=('rm -rf *' 'fg=white,bold,bg=red')

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+=('\bsudo\b' fg=123,bold)
```
This will highlight "sudo" only as a complete word, i.e., "sudo cmd", but not
"sudoedit"
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].
