Introduction

> [`:h mason-introduction`][help-mason-introduction]

`mason.nvim` is a Neovim plugin that allows you to easily manage external editor tooling such as LSP servers, DAP servers,
linters, and formatters through a single interface. It runs everywhere Neovim runs (across Linux, macOS, Windows, etc.),
with only a small set of [external requirements](#requirements) needed.

Packages are installed in Neovim's data directory ([`:h standard-path`][help-standard-path]) by default. Executables are
linked to a single `bin/` directory, which `mason.nvim` will add to Neovim's PATH during setup, allowing seamless access
from Neovim builtins (shell, terminal, etc.) as well as other 3rd party plugins.

For a list of all available packages, see <https://mason-registry.dev/registry/list>.

How to use installed packages

> [`:h mason-how-to-use-packages`][help-mason-how-to-use-packages]

Although many packages are perfectly usable out of the box through Neovim builtins, it is recommended to use other 3rd
party plugins to further integrate these. The following plugins are recommended:

-   LSP: [`lspconfig`][lspconfig] & [`mason-lspconfig.nvim`][mason-lspconfig.nvim]
-   DAP: [`nvim-dap`][nvim-dap] & [`nvim-dap-ui`][nvim-dap-ui]
-   Linters: [`null-ls.nvim`][null-ls.nvim] or [`nvim-lint`][nvim-lint]
-   Formatters: [`null-ls.nvim`][null-ls.nvim] or [`formatter.nvim`][formatter.nvim]

Requirements

> [`:h mason-requirements`][help-mason-requirements]

`mason.nvim` relaxes the minimum requirements by attempting multiple different utilities (for example, `wget`,
        `curl`, and `Invoke-WebRequest` are all perfect substitutes).
The _minimum_ recommended requirements are:

-   neovim `>= 0.7.0`
-   For Unix systems:
-   `git(1)`
-   `curl(1)` or `wget(1)`
-   `unzip(1)`
  • GNU tar (tar(1) or gtar(1) depending on platform) Note that mason.nvim will regularly shell out to external package managers, such as cargo and npm. Depending on your personal usage, some of these will also need to be installed. Refer to :checkhealth mason for a full list.

Installation

Packer

1
2
3
use {
    "williamboman/mason.nvim"
}

lazy.nvim

{
    "williamboman/mason.nvim"
}

vim-plug

Plug 'williamboman/mason.nvim'

Setup

:h mason-quickstart

1
require("mason").setup()

mason.nvim is optimized to load as little as possible during setup. Lazy-loading the plugin, or somehow deferring the setup, is not recommended.

Refer to the Configuration section for information about which settings are available.

Extensions

Refer to the Wiki for a list of 3rd party extensions.

Commands

:h mason-commands

  • :Mason - opens a graphical status window
  • :MasonUpdate - updates all managed registries
  • :MasonInstall <package> ... - installs/re-installs the provided packages
  • :MasonUninstall <package> ... - uninstalls the provided packages
  • :MasonUninstallAll - uninstalls all packages
  • :MasonLog - opens the mason.nvim log file in a new tab window

Registries

Mason's core package registry is located at mason-org/mason-registry. Before any packages can be used, the registry needs to be downloaded. This is done automatically for you when using the different Mason commands (e.g. :MasonInstall), but can also be done manually by using the :MasonUpdate command.

If you're utilizing Mason's Lua APIs to access packages, it's recommended to use the :h mason-registry.refresh() and/or :h mason-registry.update() functions to ensure you have the latest package information before retrieving packages.

Configuration

:h mason-settings

You may optionally configure certain behavior of mason.nvim when calling the .setup() function. Refer to the default configuration for a list of all available settings.
