kak-bundle

kak-bundle is a plugin manager for Kakoune designed for speed without sacrificing utility. It can install and update plugins, and optionally manage loading individual plugins and scripts for testing purposes.

Install

kak-bundle can be located anywhere on the system, but in order to manage itself, it should be installed in the plugin installation directory. By default, this is %val{config}/bundle, which in most cases expands to ~/.config/kak/bundle/, but this can be changed by setting the bundle_path option. The following assumes the default location:

mkdir -p $HOME/.config/kak/bundle/
git clone https://github.com/jdugan6240/kak-bundle $HOME/.config/kak/bundle/kak-bundle

This isn't enough by itself, though — Kakoune needs to be told to load kak-bundle. This is done by adding the following line to your kakrc:

source "%val{config}/bundle/kak-bundle/rc/kak-bundle.kak"
bundle-noload kak-bundle https://github.com/jdugan6240/kak-bundle

Alternatively, the need to load kak-bundle manually can be avoided by placing the kak-bundle repo in your autoload:

mkdir -p $HOME/.config/kak/autoload/bundle/
git clone https://github.com/jdugan6240/kak-bundle $HOME/.config/kak/autoload/bundle/kak-bundle

This option doesn't allow kak-bundle to manage itself, however.

Usage

Plugins are registered and loaded with the bundle command.

bundle kak-lsp https://github.com/kak-lsp/kak-lsp %{
  # Configure here...
  hook global KakEnd .* lsp-exit
}

The first parameter is the name of the plugin, and the second parameter is an installer (usually a URL), which must lead to a repository matching the name of the plugin. The third parameter is optional, and contains a kakscript block that runs when the plugin is loaded.

Some plugins, such as the above kak-lsp, require shell code to be executed after being installed - a compilation step, for example. This is supported with the bundle-install-hook command, as follows:

bundle-install-hook kak-lsp %{
  # Any shell code that needs to be run goes here...
  cargo install --locked --force --path .
}

It may be desirable, however, in some scenarios to grab a plugin from a specific branch or filepath. For this, kak-bundle has the concept of "installers", or custom shell code that is run to create a directory in bundle_path containing the plugin code. These are run in the bundle_path directory. Installers allow for all sorts of options regarding plugin install. Some examples are shown below:

# extract a specific branch / tag of a plugin repository:
bundle my-plugin 'git clone -b BRANCH_OR_TAG ... $URL'

# rename the clone, e.g. to avoid conflicting names:
bundle my-plugin 'git clone $URL ./my-plugin'

# load an externally-managed plugin from outside bundle_path:
bundle my-plugin 'ln -sf ~/src/my-plugin'

As with URLs, the name of the repository/directory must match the plugin name specified in the first argument.

Sometimes, it is not desirable to load every script a plugin has to offer, or they need to be loaded in a specific order. For this use case, kak-bundle allows for specifying custom loading logic for a plugin with the bundle-customload command. An example of this for kakoune-extra:

bundle-customload kakoune-extra https://github.com/lenormf/kakoune-extra %{
  # Custom loading logic here...
  source "%opt{bundle_path}/kakoune-extra/fzf.kak"
  source "%opt{bundle_path}/kakoune_extra/tldr.kak"
  source "%opt{bundle_path}/kakoune_extra/utils.kak"

  # Configuration goes here too...
}

In this case, three arguments are required - the plugin name, the installer, and the code block containing the custom loading logic.

Finally, kak-bundle provides a command, bundle-noload, to register a plugin without loading it. This is useful, for example, for testing how plugins behave when other plugins aren't loaded. An example:

bundle-noload kak-lsp https://github.com/kak-lsp/kak-lsp.git %{
  # This configuration code isn't run on startup...
}

As before, the installer specified in the second argument must match the plugin name specified in the first argument.

Once these commands are written in your kakrc for the first time, the kakrc must be re-sourced to inform kak-bundle about the registered plugins. To avoid collisions with redefining existing commands/options, this is best done by restarting Kakoune.

After this is done, the registered plugins can be installed with the bundle-install command, and installed plugins can be uninstalled with the bundle-clean command. bundle-install and bundle-clean can also accept individual plugins as arguments to install/uninstall selectively.

Some plugins, when installed, leave behind artifacts that aren't removed by just removing the plugin repository (kak-lsp for example). For this use case, kak-bundle supports defining cleaners, which is shell code run after running the bundle-clean command. For example:

bundle-cleaner kak-lsp %{
  rm ~/.cargo/bin/kak-lsp
}

Now, when running bundle-clean kak-lsp, in addition to the plugin repo being removed from bundle_path, the kak-lsp binary is removed as well.

Plugins may receive updates after being installed. Use the bundle-install command to update all installed plugins, or pass specific plugins as arguments to update selectively:

bundle-install                        # update all plugins
bundle-install kak-lsp kakoune-extra  # update individual plugins

Tips and Tricks

Colorschemes

kak-bundle doesn't support colorschemes by default, but they're pretty easy to support by running post-install code. Take this example for one.kak:

bundle-noload one.kak https://github.com/raiguard/one.kak # Notice, no config block
bundle-install-hook one.kak %{
  # Post-install code here...
  mkdir -p ${kak_config}/colors
  ln -sf "${kak_opt_bundle_path}/one.kak" "${kak_config}/colors/"
}
# The below command is optional, but allows for cleanly uninstalling the colorscheme
bundle-cleaner one.kak %{
  # Remove the symlink
  rm -rf "${kak_config}/colors/one.kak"
}
# Set the colorscheme later on in the kakrc...
colorscheme one-dark

The bundle-noload command is necessary in this case, as otherwise the colorscheme would be loaded immediately, which may conflict with other installed colorschemes.

Bootstrap kak-bundle

The process of installing and loading kak-bundle can be automated, at a slight load time cost, by adding the following to the top of your kakrc:

evaluate-commands %sh{
  # We're assuming the default bundle_path here...
  plugins="$kak_config/bundle"
  mkdir -p "$plugins"
  [ ! -e "$plugins/kak-bundle" ] && \
    git clone -q https://github.com/jdugan6240/kak-bundle "$plugins/kak-bundle"
  printf "%s\n" "source '$plugins/kak-bundle/rc/kak-bundle.kak'"
}
bundle-noload kak-bundle https://github.com/jdugan6240/kak-bundle

This will create the needed directories on Kakoune launch, and download kak-bundle if not installed already.

Running bundle-install outside of Kakoune

It can be desirable to update plugins outside of Kakoune - say, as part of a systemwide upgrade process. kak-bundle provides support for this in the form of its bundle-after-install hook, which is a user-defined hook that is triggered upon completion of bundle-install. Place the following in your kakrc:

hook global User bundle-after-install %{
  # This is run after bundle-install completes.
  # This could be for automatically deleting the *bundle* buffer, or some other similar action.
  # In this case, we want to exit Kakoune, so we return to the command line.
  quit!
}

Then, run the following on the command line: kak -e 'bundle-install'. kak-bundle will update the plugins, and then trigger the hook, quitting Kakoune and returning you to the command line.

kak-bundle Configuration

kak-bundle provides the following options that can be used to change how kak-bundle works:

  • bundle_path — This dictates the directory kak-bundle installs plugins to. This is %val{config}/bundle by default.
  • bundle_parallel4 by default, this determines how many parallel install/update jobs bundle-install can spawn; set to 1 to disable parallelism.

In addition, kak-bundle provides some user-defined hooks to further customize how kak-bundle works. None are defined by default. They are:

  • bundle-after-install — This is run immediately after bundle-install completes (including the post-install code defined for each plugin). Example: hook global User bundle-after-install %{ try %{ delete-buffer *bundle* } }

Performance

kak-bundle is designed for speed, and runs no shell code on startup. This makes its load time pretty close to optimal.

The following load times were obtained using the benchmark suite in the benchmark/ directory on the author's machine (your exact times may vary):

Plugin Manager Mean [ms] Min [ms] Max [ms]
kak-bundle 237.5 +- 17.8 218.0 278.4
cork.kak 255.8 +- 10.6 244.4 280.4
plug.kak 375.4 +- 24.1 346.4 425.0
