A minimal plugin-manager for vis

vis-plug plugins are defined by a Lua file in a git repository and can be both a plugin or a theme.

Configure plugins in your visrc and use Commands to install and more.

Plugins are installed using git (in the background) to a cache folder and required on init.

git clone vis-plug and require it in your visrc.

You can use this one-liner to install vis-plug and then require it in your visrc:

[ -n "${XDG_CONFIG_HOME:-$HOME}" ] && [ -d "${XDG_CONFIG_HOME:-$HOME/.config}/vis/plugins" ] && git clone https://github.com/erf/vis-plug.git "${XDG_CONFIG_HOME:-$HOME/.config}/vis/plugins/vis-plug" || echo "Error: The plugin path could not be determined or does not exist. Ensure XDG_CONFIG_HOME or HOME is set and that the path exists."

Alternatively, you can add the following to your visrc to automatically fetch vis-plug to your plugins folder and require it:

local plug = (function() if not pcall(require, 'plugins/vis-plug') then
 	os.execute('git clone --quiet https://github.com/erf/vis-plug ' ..
	 	(os.getenv('XDG_CONFIG_HOME') or os.getenv('HOME') .. '/.config')
	 	.. '/vis/plugins/vis-plug')
end return require('plugins/vis-plug') end)()

Configure plugins in your visrc as a list of tables given to the plug.init method.

Example:

local plug = require('plugins/vis-plug')

-- configure plugins in an array of tables with git urls and options
local plugins = {

	-- load a plugin given a repo (https://github.com/ can be omitted and expects a 'init.lua' file)
	{ 'erf/vis-cursors' },

	-- first parameter is a shorthand for 'url'
	{ url = 'erf/vis-cursors' },

	-- specify the lua file to require (or theme to set) and give a ref (commit, branch, tag) to checkout
	{ 'erf/vis-test', file = 'test', ref = 'some-branch' },

	-- specify an alias to later use to access plugin variables (see example below)
	{ 'erf/vis-highlight', alias = 'hi' },

	-- configure themes by setting 'theme = true'. The theme 'file' will be set on INIT
	{ 'samlwood/vis-gruvbox', theme = true, file = 'gruvbox' },
}

-- require and optionally install plugins on init
plug.init(plugins, true)

-- access plugins via alias
plug.plugins.hi.patterns[' +\n'] = { style = 'back:#444444' }

Each plugin table can have the following options:

• url - the url to the git repo (https://github.com or https:// can be omitted)
• file - the relative path to the lua file (defaults to init, skip the .lua part) (optional)
• ref - checkout a spesific commit, branch or tag (optional)
• alias - access plugins via plug.plugins.{alias} (optional)
• theme - set theme = true if theme; will set theme on INIT event (optional)

Pass true as second argument to init to install on init.

require('plugins/vis-plug').init(plugins, true)

Plugins are installed (cloned) to the following path (in this order):

(VIS_PLUG_HOME|(XDG_CACHE_HOME|HOME/.cache)/vis-plug)/{plugins|themes}

Use plug.path to set a custom install path:

plug.path('/Users/user/my-plugins')

Install themes using the { theme = true, file = 'somepath/theme-file' } option (don't include .lua)

The first theme in the config table is set on the INIT event.

Example theme:

local plugins = {
	{ 'timoha/vis-acme', theme = true, file = 'acme' },
}

We support the following vis commands:

:plug-list - list plugins and themes

:plug-install - install plugins (git clone)

:plug-update - update outdated plugins (git pull)

:plug-outdated - check if plugins are up-to-date

:plug-upgrade - upgrade to latest vis-plug using git pull

:plug-remove - delete plugin by {name} (:plug-list for names)

:plug-clean - delete all plugins from disk

:plug-checkout - checkout {name} {commit|branch|tag}

:plug-commands - list commands (these)

I've created vis-plugins - a web page with is a list of plugins and themes based on the vis wiki.
