Add %Bzmodule%b calls to your %B${ZDOTDIR:-${HOME}}/.zimrc%b file to define the modules to be initialized.
The modules are initialized in the same order they are defined.
<url> Module absolute path or repository URL. The following URL formats
are equivalent: %Bname%b, %Bzimfw/name%b, %Bhttps://github.com/zimfw/name.git%b.
%B-n%b|%B--name%b <module_name> Set a custom module name. Default: the last component in the <url>.
Use slashes inside the name to organize the module into subdirecto-
ries.
Repository options:
%B-b%b|%B--branch%b <branch_name> Use specified branch when installing and updating the module.
Overrides the tag option. Default: the repository's default branch.
%B-t%b|%B--tag%b <tag_name> Use specified tag when installing and updating the module.
Overrides the branch option.
%B-u%b|%B--use%b <%Bgit%b|%Bdegit%b> Install and update the module using the defined tool. Default is
defined by %Bzstyle ':zim:zmodule' use '%b<%Bgit%b|%Bdegit%b>%B'%b, or %Bgit%b if none
is provided.
2021-08-25 17:09:10 -04:00
%Bgit%b requires git itself. Local changes are preserved during updates.
2021-08-10 10:56:25 -04:00
%Bdegit%b requires curl or wget, and currently only works with GitHub
URLs. Modules install faster and take less disk space. Local changes
are lost during updates. Git submodules are not supported.
%B-z%b|%B--frozen%b Don't install or update the module.
Initialization options:
%B-f%b|%B--fpath%b <path> Add specified path to fpath. The path is relative to the module
root directory. Default: %Bfunctions%b, if the subdirectory exists.
%B-a%b|%B--autoload%b <func_name> Autoload specified function. Default: all valid names inside the
module's specified fpath paths.
%B-s%b|%B--source%b <file_path> Source specified file. The file path is relative to the module root
2021-03-19 19:44:53 -04:00
directory. Default: %Binit.zsh%b, if the %Bfunctions%b subdirectory also
exists, or the file with largest size matching
%B{init.zsh,module_name.{zsh,plugin.zsh,zsh-theme,sh}}%b, if any exist.
%B-c%b|%B--cmd%b <command> Execute specified command. Occurrences of the %B{}%b placeholder in the
command are substituted by the module root directory path.
I.e., %B-s 'script.zsh'%b and %B-c 'source {}/script.zsh'%b are equivalent.
%B-d%b|%B--disabled%b Don't initialize or uninstall the module."
