❮ ZI ❯ Annex - Eval Allows to cache the output of arbitrarily slow initialization command to speed up shell startup time.

Synopsis:

zi recache <plugin/snippet>

In order to enable tab completion for the new subcommand set the value Z_A_USECOMP=1 somewhere before loading this plugin.

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

💡 Wiki

• annexes

Installation

Simply load like a regular plugin:

zi light z-shell/z-a-eval

After executing this command you can then use the new ice-mods provided by the annex.

How it works

The output of a slow initialization command is redirected to a file located within the plugin/snippets directory and sourced while loading. The next time the plugin/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/snippets root directory which stores the commands output.

This cache is regenerated when:

• The plugin/snippet is updated.
• The cache file is removed.
• With the new ZI subcommand recache.

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

Example Invocations

Without z-a-eval

zi ice as"command" from"gh-r" mv"zoxide* -> zoxide"  \
  atclone"./zoxide init 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

With z-a-eval

zi ice as"command" from"gh-r" mv"zoxide* -> zoxide" \
  eval"./zoxide init 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

Without ZI

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

With ZI and z-a-eval

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