# 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](#configuration) section below).
Uses [Mason](https://github.com/williamboman/mason.nvim) 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](https://github.com/williamboman/mason.nvim). And, of course,
this plugin requires that Mason be installed.
Optionally:
- [mason-lspconfig](https://github.com/williamboman/mason-lspconfig.nvim) can be installed for the
option to use lspconfig names instead of Mason names.
- [mason-null-ls](https://github.com/jay-babu/mason-null-ls.nvim) can be installed for the
option to use null-ls names instead of Mason names.
- [mason-nvim-dap](https://github.com/jay-babu/mason-nvim-dap.nvim) 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:
```vim
Plug 'WhoIsSethDaniel/mason-tool-installer.nvim'
```
Or if you use Vim 8 style packages:
```bash
cd
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.
```lua
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:
```lua
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:
```lua
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,
})
```
