mason-tool-installer

Install or upgrade all of your third-party tools.

Can run at startup or may be run manually via a command (see the Configuration section below).

Uses Mason to do nearly all the work. This is a simple plugin that helps users keep up-to-date with their tools and to make certain they have a consistent environment.

Requirements

This plugin has the same requirements as Mason. And, of course, this plugin requires that Mason be installed.

Optionally:

• mason-lspconfig can be installed for the option to use lspconfig names instead of Mason names.
• mason-null-ls can be installed for the option to use null-ls names instead of Mason names.
• mason-nvim-dap can be installed for the option to use nvim-dap names instead of Mason names.

Installation

Install using your favorite plugin manager.

If you use vim-plug:

Plug 'WhoIsSethDaniel/mason-tool-installer.nvim'

Or if you use Vim 8 style packages:

cd <plugin dir>
git clone https://github.com/WhoIsSethDaniel/mason-tool-installer.nvim

Configuration

When passing a list of tools to ensure_installed, mason-tool-installer is expecting Mason package names by default.

If mason-lspconfig is installed, mason-tool-installer can accept lspconfig package names unless the integration is disabled.

If mason-null-ls is installed, mason-tool-installer can accept null-ls package names unless the integration is disabled.

If mason-nvim-dap is installed, mason-tool-installer can accept nvim-dap package names unless the integration is disabled.

require('mason-tool-installer').setup {

  -- a list of all tools you want to ensure are installed upon
  -- start
  ensure_installed = {

    -- you can pin a tool to a particular version
    { 'golangci-lint', version = 'v1.47.0' },

    -- you can turn off/on auto_update per tool
    { 'bash-language-server', auto_update = true },

    'lua-language-server',
    'vim-language-server',
    'gopls',
    'stylua',
    'shellcheck',
    'editorconfig-checker',
    'gofumpt',
    'golines',
    'gomodifytags',
    'gotests',
    'impl',
    'json-to-struct',
    'luacheck',
    'misspell',
    'revive',
    'shellcheck',
    'shfmt',
    'staticcheck',
    'vint',
  },

  -- if set to true this will check each tool for updates. If updates
  -- are available the tool will be updated. This setting does not
  -- affect :MasonToolsUpdate or :MasonToolsInstall.
  -- Default: false
  auto_update = false,

  -- automatically install / update on startup. If set to false nothing
  -- will happen on startup. You can use :MasonToolsInstall or
  -- :MasonToolsUpdate to install tools and check for updates.
  -- Default: true
  run_on_start = true,

  -- set a delay (in ms) before the installation starts. This is only
  -- effective if run_on_start is set to true.
  -- e.g.: 5000 = 5 second delay, 10000 = 10 second delay, etc...
  -- Default: 0
  start_delay = 3000, -- 3 second delay

  -- Only attempt to install if 'debounce_hours' number of hours has
  -- elapsed since the last time Neovim was started. This stores a
  -- timestamp in a file named stdpath('data')/mason-tool-installer-debounce.
  -- This is only relevant when you are using 'run_on_start'. It has no
  -- effect when running manually via ':MasonToolsInstall' etc....
  -- Default: nil
  debounce_hours = 5, -- at least 5 hours between attempts to install/update

  -- By default all integrations are enabled. If you turn on an integration
  -- and you have the required module(s) installed this means you can use
  -- alternative names, supplied by the modules, for the thing that you want
  -- to install. If you turn off the integration (by setting it to false) you
  -- cannot use these alternative names. It also suppresses loading of those
  -- module(s) (assuming any are installed) which is sometimes wanted when
  -- doing lazy loading.
  integrations = {
    ['mason-lspconfig'] = true,
    ['mason-null-ls'] = true,
    ['mason-nvim-dap'] = true,
  },
}

Commands

:MasonToolsInstall - only installs tools that are missing or at the incorrect version

:MasonToolsInstallSync - execute :MasonToolsInstall in blocking manner. It's useful in Neovim headless mode.

:MasonToolsUpdate - install missing tools and update already installed tools

:MasonToolsUpdateSync - execute :MasonToolsUpdate in blocking manner. It's useful in Neovim headless mode.

:MasonToolsClean - remove installed packages that are not listed in ensure_installed

Events

Prior to installing the first package mason-tool-installer will emit a user event named MasonToolsStartingInstall. If there are no packages to install then no event will be emitted. This event will only be emitted once -- at the start of installing packages. To use this event you can setup an event handler like so:

  vim.api.nvim_create_autocmd('User', {
    pattern = 'MasonToolsStartingInstall',
    callback = function()
      vim.schedule(function()
        print 'mason-tool-installer is starting'
      end)
    end,
  })

Upon completion of any mason-tool-installer initiated installation/update a user event will be emitted named MasonToolsUpdateCompleted. If you have at least neovim 0.8 the programs that were just installed or updated will be in the data element of the argument to the callback (see :h nvim_create_autocmd for much more information). To use this event you can setup an event handler like so:

  vim.api.nvim_create_autocmd('User', {
    pattern = 'MasonToolsUpdateCompleted',
    callback = function(e)
      vim.schedule(function()
        print(vim.inspect(e.data)) -- print the table that lists the programs that were installed
      end)
    end,
  })
