## 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`:

```vim
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).

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

`.vimrc`:
```vim
packloadall
```

Install with [vim-plug](https://github.com/junegunn/vim-plug), assumes node and
yarn|npm installed globally.

```vim
" 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:

```vim
" 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](https://github.com/tpope/vim-pathogen), you can run the following in a terminal:

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

If using [dein](https://github.com/Shougo/dein.vim), add the following to your dein config:

```vim
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`](https://github.com/hugomrdias/prettier-stylelint), set
this at the buffer level, e.g.:

```vim
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:

```vim
<Leader>p
```

or

```vim
:Prettier
```

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

```vim
: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.

```vim
: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.

```vim
:PrettierFragment
```

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

```vim
: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:

```vim
:PrettierCliPath
```

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

```vim
:PrettierCliVersion
```

### Configuration

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

```vim
nmap <Leader>py <Plug>(Prettier)
```

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

```vim
let g:prettier#autoformat = 1
```

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

```vim
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

```vim
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!

```vim
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.

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

Set the prettier CLI executable path

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

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

```vim
let g:prettier#exec_cmd_async = 1
```

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

```vim
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:

```vim
let g:prettier#partial_format=1
```

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

```vim
let g:prettier#quickfix_auto_focus = 0
```

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

```vim
" 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:

```vim
" 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
