3. Start a new terminal session.
## Usage
@ -27,35 +54,22 @@ If you invoke the `forward-word` widget, it will partially accept the suggestion
## Configuration
You may want to override the default global config variables. Default values of these variables can be found [here](src/config.zsh).
You may want to override the default global config variables after sourcing the plugin. 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**.
Set `ZSH_AUTOSUGGEST_HIGHLIGHT_STYLE` to configure the style that the suggestion is shown with. The default is `fg=8`.
### 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:
Set `ZSH_AUTOSUGGEST_STRATEGY` to choose the strategy for generating suggestions. There are currently two 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, which is included with zsh since 4.0.1)
- `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.
- `default`: Chooses the most recent match.
- `match_prev_cmd`: Chooses the most recent match whose preceding history item matches the most recently executed command ([more info](src/strategies/match_prev_cmd.zsh)).
### Widget Mapping
@ -66,52 +80,19 @@ This plugin works by triggering custom behavior when certain [zle widgets](http:
- `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.
Widgets not in any of these lists will update the suggestion when 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`:
This plugin provides three 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.

### 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.
Testing is performed with [`shunit2`](https://github.com/kward/shunit2) (v2.1.6). Documentation can be found [here](http://shunit2.googlecode.com/svn/trunk/source/2.1/doc/shunit2.html).
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`).
It's possible to run the tests for any supported version of zsh in a Docker image by building an image from the provided Dockerfile. To build the docker image for a specific version of zsh (where `<version>` below is substituted with the contents of a line from the [`ZSH_VERSIONS`](ZSH_VERSIONS) file), run:
```sh
docker build --build-arg TEST_ZSH_VERSION=<version> -t zsh-autosuggestions-test .
```
After building the image, run the tests via:
```sh
docker run -it -v $PWD:/zsh-autosuggestions zsh-autosuggestions-test make test
```
The test script lives at `script/test.zsh`. To run the tests, run `make test`.
