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 please add this to your .vimrc:

Plug 'prettier/vim-prettier', {
  \ 'do': 'yarn install --frozen-lockfile --production',
  \ 'branch': 'release/0.x'
  \ }

---

By default it will auto format javascript, typescript, less, scss, css, json, graphql and markdown files 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 and yarn|npm installed globally.

" post install (yarn install | npm install) then load plugin only for editing supported files
Plug 'prettier/vim-prettier', {
  \ 'do': 'yarn install --frozen-lockfile --production',
  \ 'for': ['javascript', 'typescript', 'css', 'less', 'scss', 'json', 'graphql', 'markdown', 'vue', 'svelte', 'yaml', 'html'] }

or simply enable for all formats by:

" post install (yarn install | npm install) then load plugin only for editing supported files
Plug 'prettier/vim-prettier', { 'do': 'yarn install --frozen-lockfile --production' }

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'})

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 either do npm install or yarn install --frozen-lockfile

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 parents and search for Prettier installation inside node_modules
3. Look for a global prettier installation
4. Use locally installed vim-prettier prettier executable

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 current 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 for when using the g:prettier#autoformat_config_present option.

let g:prettier#autoformat_config_files = [...]

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,*.svelte,*.yaml,*.html 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 = ''

" 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
