prettier/vim-prettier

vim-prettier

A vim plugin wrapper for prettier, pre-configured with custom default prettier settings.

---

NOTE: If you want to fallback to older version of prettier/vim-prettier, use the release/0.x branch and follow that branch's install instructions:

Plug 'prettier/vim-prettier', { 'branch': 'release/0.x' }

---

By default it will auto format configured filetype patterns if they have/support the "@format" pragma annotation in the header of the file.

INSTALL

To install with vim 8+ plugins, simply clone to your ~/.vim/pack/plugins/start directory, and add packloadall to your .vimrc (if you haven't already).

mkdir -p ~/.vim/pack/plugins/start
git clone https://github.com/prettier/vim-prettier ~/.vim/pack/plugins/start/vim-prettier

.vimrc:

packloadall

Install with vim-plug, assumes Node.js and npm are installed globally.

" post install with npm, then load plugin only for selected filetypes
Plug 'prettier/vim-prettier', {
  \ 'do': 'npm install --omit=dev',
  \ 'for': ['javascript', 'typescript', 'css', 'less', 'scss', 'json', 'graphql', 'markdown', 'vue', 'yaml', 'html', 'php', 'xml'] }

or load vim-prettier for every filetype by:

" post install with npm, then load plugin for every filetype
Plug 'prettier/vim-prettier', { 'do': 'npm install --omit=dev' }

For those using vim-pathogen, you can run the following in a terminal:

cd ~/.vim/bundle
git clone https://github.com/prettier/vim-prettier

If using dein, add the following to your dein config:

call dein#add('prettier/vim-prettier', {'build': 'npm install --omit=dev'})

If using other vim plugin managers or doing manual setup make sure to have prettier installed globally or go to your vim-prettier directory and run npm install --omit=dev.

Prettier Executable resolution

When installed via vim-plug, a default prettier executable is installed inside vim-prettier.

vim-prettier executable resolution:

1. Look for user defined prettier cli path from vim configuration file
2. Traverse the current buffer's parents and search for Prettier installation inside node_modules
3. Look for a global prettier installation
4. Use locally installed vim-prettier prettier executable

Compatibility status

The 2.0.0 beta support policy is based on tested fixtures. Project-local Prettier, configuration, and plugins take precedence over vim-prettier's bundled fallback.

Tested editors are Vim 8.2 latest patch, latest stable Vim, Neovim 0.9 latest patch, and latest stable Neovim. Formatting fixtures cover core Prettier languages with the bundled Prettier baseline, Prettier 2.8.8, and latest Prettier.

User installs are tested with Node.js 20.x and npm install --omit=dev. Development and CI use the checked-in Yarn v1 lockfile with yarn install --frozen-lockfile for reproducible test runs.

The root Dockerfile is deprecated and kept only for historical reference. It uses Alpine 3.8, an unpinned testbed/vim:latest base image, and legacy editor versions; it is not an authoritative compatibility environment.

For local editor-matrix smoke checks, use the pinned Docker runner:

yarn test:editors:docker

To run one target, use:

scripts/docker-editor-matrix.sh vim-8.2
scripts/docker-editor-matrix.sh vim-stable
scripts/docker-editor-matrix.sh nvim-0.9
scripts/docker-editor-matrix.sh nvim-stable

The Docker runner defaults to linux/amd64 so Neovim release archives are available consistently. Neovim targets currently assume x86_64 release archives; do not override DOCKER_PLATFORM for Neovim unless the Dockerfile is updated to select a matching asset. Override VIM_STABLE_VERSION to test a newer stable Vim tag. Override DOCKER_MATRIX_COMMAND to run a different command inside the matrix image. The checkout is mounted read-write, but node_modules and Yarn cache are isolated in Docker volumes.

Prettier Stylelint

To use an alternative command, like prettier-stylelint, set this at the buffer level, e.g.:

au FileType css,scss let b:prettier_exec_cmd = "prettier-stylelint"

vim-prettier will look for the executable in the same places it looks for prettier, and will fall back to prettier if it can't find b:prettier_exec_cmd

USAGE

Prettier by default will run on auto save but can also be manually triggered by:

<Leader>p

or

:Prettier

If your are on vim 8+ you can also trigger async formatting by:

:PrettierAsync

You can send to prettier your entire buffer but ensure that it formats only your selection.

note: differs from :PrettierFragment by sending the entire buffer to prettier, allowing identation level to be preserved, but it requires the whole file to be valid.

:PrettierPartial

You can send to prettier your current selection as a fragment of same type as the file being edited.

note: differs from :PrettierPartial by sending only the current selection to prettier, this allows for faster formatting but wont preserve indentation.

:PrettierFragment

You can check what is the vim-prettier plugin version by:

:PrettierVersion

You can send commands to the resolved prettier cli by:

:PrettierCli <q-args>

You can check what is the resolved prettier cli path by:

:PrettierCliPath

You can check what is the resolved prettier cli version by:

:PrettierCliVersion

Configuration

Change the mapping to run from the default of <Leader>p

nmap <Leader>py <Plug>(Prettier)

Enable auto formatting of files that have "@format" or "@prettier" tag

let g:prettier#autoformat = 1

Allow auto formatting for files without "@format" or "@prettier" tag

let g:prettier#autoformat_require_pragma = 0

NOTE The previous two options can be used together for autoformatting files on save without @format or @prettier tags

let g:prettier#autoformat = 1
let g:prettier#autoformat_require_pragma = 0

Toggle the g:prettier#autoformat setting based on whether a config file can be found in the buffer's directory or any parent directory. Note that this will override the g:prettier#autoformat setting!

let g:prettier#autoformat_config_present = 1

A list containing all config file names to search from the buffer's directory and parent directories when using the g:prettier#autoformat_config_present option. The default list follows Prettier's documented file-based config names and keeps vim-prettier's legacy .prettierrc.config.js entry. It intentionally does not include package.json or package.yaml, because those files only count as Prettier configs when they contain a prettier key. Detection only controls whether autoformat runs; the selected Prettier executable and Node version still determine whether a detected config format can be parsed.

let g:prettier#autoformat_config_files = [
      \ '.prettierrc',
      \ '.prettierrc.json',
      \ '.prettierrc.yaml',
      \ '.prettierrc.yml',
      \ '.prettierrc.json5',
      \ '.prettierrc.js',
      \ '.prettierrc.mjs',
      \ '.prettierrc.cjs',
      \ '.prettierrc.ts',
      \ '.prettierrc.mts',
      \ '.prettierrc.cts',
      \ 'prettier.config.js',
      \ 'prettier.config.mjs',
      \ 'prettier.config.cjs',
      \ 'prettier.config.ts',
      \ 'prettier.config.mts',
      \ 'prettier.config.cts',
      \ '.prettierrc.toml',
      \ '.prettierrc.config.js']

Set the prettier CLI executable path

let g:prettier#exec_cmd_path = "~/path/to/cli/prettier"

The command :Prettier by default is synchronous but can also be forced async

let g:prettier#exec_cmd_async = 1

By default parsing errors will open the quickfix but can also be disabled

let g:prettier#quickfix_enabled = 0

By default selection formatting will be running :PrettierFragment but we can set :PrettierPartial as the default selection formatting by:

let g:prettier#partial_format=1

By default we auto focus on the quickfix when there are errors but can also be disabled

let g:prettier#quickfix_auto_focus = 0

To run vim-prettier not only before saving, but also after changing text or leaving insert mode:

" when running at every change you may want to disable quickfix
let g:prettier#quickfix_enabled = 0

autocmd TextChanged,InsertLeave *.js,*.jsx,*.mjs,*.ts,*.tsx,*.css,*.less,*.scss,*.json,*.graphql,*.md,*.vue,*.yaml,*.html,*.php,*.xml PrettierAsync

Overwrite default prettier configuration

Note: vim-prettier default settings differ from prettier intentionally. However they can be configured by:

" Max line length that prettier will wrap on: a number or 'auto' (use
" textwidth).
" default: 'auto'
let g:prettier#config#print_width = 'auto'

" number of spaces per indentation level: a number or 'auto' (use
" softtabstop)
" default: 'auto'
let g:prettier#config#tab_width = 'auto'

" use tabs instead of spaces: true, false, or auto (use the expandtab setting).
" default: 'auto'
let g:prettier#config#use_tabs = 'auto'

" flow|babylon|typescript|css|less|scss|json|graphql|markdown or empty string
" (let prettier choose).
" default: ''
let g:prettier#config#parser = ''

" Prettier plugin paths to load. Accepts a string or list of strings.
" Project-local Prettier installs should provide their own project-local plugins.
" default: []
let g:prettier#config#plugins = []

" cli-override|file-override|prefer-file
" default: 'file-override'
let g:prettier#config#config_precedence = 'file-override'

" always|never|preserve
" default: 'preserve'
let g:prettier#config#prose_wrap = 'preserve'

" css|strict|ignore
" default: 'css'
let g:prettier#config#html_whitespace_sensitivity = 'css'

" false|true
" default: 'false'
let g:prettier#config#require_pragma = 'false'

" Define the flavor of line endings
" lf|crlf|cr|all
" defaut: 'lf'
let g:prettier#config#end_of_line = get(g:, 'prettier#config#end_of_line', 'lf')

REQUIREMENT(S)

If the prettier executable can't be found by Vim, no code formatting will happen.

For normal use, install dependencies with Node.js 20.x and npm install --omit=dev. For development and compatibility verification, use yarn install --frozen-lockfile so the checked-in Yarn v1 lockfile is respected.
