🌀 Eval

The output of a slow initialization command is redirected to a file located within the plugin or snippets directory and sourced while loading. The next time the plugin or snippet is loaded, this file will be sourced skipping the need to run the initialization command.

The ice-modifier eval'…' provided and handled by this annex creates a cache in the plugin or snippets directory which stores the output of the command and the cache is regenerated when:

1. The plugin or snippet is updated.
2. The cache file is removed.
3. When running zi recache.

备注

The optional preceding ! flag means to store command output regardless of exit code. Otherwise eval'…' will avoid caching the output of code which returns a non-zero exit code.

Example invocations

No Eval + Zi

zi ice as"command" from"gh-r" \
  atclone"./zoxide init --cmd x zsh > init.zsh" \
  atpull"%atclone" src"init.zsh" nocompile'!'
zi light ajeetdsouza/zoxide

zi ice atclone"dircolors -b LS_COLORS > init.zsh" \
  atpull"%atclone" pick"init.zsh" nocompile'!' \
  atload'zstyle ":completion:*" list-colors ${(s.:.)LS_COLORS}'
zi light trapd00r/LS_COLORS

Eval + Zi

zi ice as"command" from"gh-r" \
  eval"./zoxide init --cmd x zsh"
zi light ajeetdsouza/zoxide

zi ice eval"dircolors -b LS_COLORS" \
  atload'zstyle ":completion:*" list-colors ${(s.:.)LS_COLORS}'
zi light trapd00r/LS_COLORS

No Zi + Eval

if [[ "${+commands[kubectl]}" == 1 ]]; then
  eval $(kubectl completion zsh)
fi

Zi + Eval

zi ice id-as"kubectl_completion" has"kubectl" \
  eval"kubectl completion zsh" run-atpull
zi light z-shell/null

Install eval

Source

• z-shell/z-a-eval

Default

Add the following snippet in the .zshrc file:

zi light z-shell/z-a-eval

Enable Completion

Add the following snippet in the .zshrc file:

Set value Z_A_USECOMP=1 to enable TAB completion for subcommand recache.

zi ice atinit'Z_A_USECOMP=1'
zi light z-shell/z-a-eval

This will register subcommand recache and eval'…' ice-modifier.
