Suggestions are fetched asynchronously by default in zsh versions 5.0.8 and greater. This can be useful when pasting large amount of text in the terminal, to avoid triggering autosuggestion for strings that are too long. The default is unset, which means that autosuggestion will be tried for any buffer size. Set ZSH_AUTOSUGGEST_BUFFER_MAX_SIZE to an integer value to disable autosuggestion for large buffers. Note: A widget shouldn't belong to more than one of the above arrays. Widgets that modify the buffer and are not found in any of these arrays will fetch a new suggestion after they are invoked. ZSH_AUTOSUGGEST_IGNORE_WIDGETS: Widgets in this array will not trigger any custom behavior.ZSH_AUTOSUGGEST_PARTIAL_ACCEPT_WIDGETS: Widgets in this array will partially accept the suggestion when invoked.ZSH_AUTOSUGGEST_EXECUTE_WIDGETS: Widgets in this array will execute the suggestion when invoked.ZSH_AUTOSUGGEST_ACCEPT_WIDGETS: Widgets in this array will accept the suggestion when invoked.ZSH_AUTOSUGGEST_CLEAR_WIDGETS: Widgets in this array will clear the suggestion when invoked.

You can add and remove widgets from these arrays to change the behavior of this plugin: This plugin works by triggering custom behavior when certain zle widgets are invoked. 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.įor 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.

match_prev_cmd: Like history, but chooses the most recent match whose preceding history item matches the most recently executed command ( more info).

completion: Chooses a suggestion based on what tab-completion would suggest.

history: Chooses the most recent match from history.

There are currently three built-in strategies to choose from: The strategies in the array are tried successively until a suggestion is found. ZSH_AUTOSUGGEST_STRATEGY is an array that specifies how suggestions should be generated. 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. If this affects you, the problem is likely caused by incorrect color settings. Note: Some iTerm2 users have reported not being able to see the suggestions. ZSH_AUTOSUGGEST_HIGHLIGHT_STYLE= "fg=#ff00ff,bg=cyan,bold,underline "įor more info, read the Character Highlighting section of the zsh manual: man zshzle or online. For example, this would show suggestions with bold, underlined, pink text on a cyan background: If your terminal only supports 8 colors, you will need to use a number between 0 and 7.īackground color can also be set, and the suggestion can be styled bold, underlined, or standout. The default is fg=8, which will set the foreground color to color 8 from the 256-color palette. Set ZSH_AUTOSUGGEST_HIGHLIGHT_STYLE to configure the style that the suggestion is shown with.

See their comments on overriding internals. Note: If you are using Oh My Zsh, you can put this configuration in a file in the $ZSH_CUSTOM directory. Default values of these variables can be found here. You may want to override the default global config variables. If you invoke the forward-word widget, it will partially accept the suggestion up to the point that the cursor moves to. If you press the → key ( forward-char widget) or End ( 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. This color can be changed by setting the ZSH_AUTOSUGGEST_HIGHLIGHT_STYLE variable. It suggests commands as you type based on history and completions.Īs you type commands, you will see a completion offered after the cursor in a muted gray color. Fish-like fast/unobtrusive autosuggestions for zsh.
