The `zsh-autosuggestions` package provides several configuration options
such as a different highlight style (like `fg=cyan` which is easier to
read).
With `rename.nix` the old `programs.zsh.enableAutosuggestions` is still
functional, but yields the following warning like this during evaluation:
```
trace: warning: The option `programs.zsh.enableAutosuggestions' defined in `<unknown-file>' has been renamed to `programs.zsh.autosuggestions.enable'.
```
The module provides the most common `zsh-autosuggestions` (highlight
style and strategy) as options that will be written into the interactive
shell init (`/etc/zshrc` by default). Further configuration options can
be declared using the `extraConfig` attr set:
```
{
programs.zsh.autosuggestions.extraConfig = {
"ZSH_AUTOSUGGEST_BUFFER_MAX_SIZE" = "buffer_size";
};
}
```
A full list of available configuration options for `zsh-autosuggestions`
can be viewed here: https://github.com/zsh-users/zsh-autosuggestions/blob/v0.4.3/README.md

Set ZSH_AUTOSUGGEST_STRATEGY to choose the strategy for generating suggestions.
|
|
There are currently two to choose from:
|
|
|
|
* 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). 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.
