Neoformat

A (Neo)vim plugin for formatting code.

Neoformat uses a variety of formatters for many filetypes. Currently, Neoformat will run a formatter using the current buffer data, and on success it will update the current buffer with the formatted text. On a formatter failure, Neoformat will try the next formatter defined for the filetype.

By using getbufline() to read from the current buffer instead of file, Neoformat is able to format your buffer without you having to :w your file first. Also, by using setline(), marks, jumps, etc. are all maintained after formatting.

Neoformat supports both sending buffer data to formatters via stdin, and also writing buffer data to /tmp/ for formatters to read that do not support input via stdin.

Basic Usage

Format the entire buffer, or visual selection of the buffer

:Neoformat

Or specify a certain formatter (must be defined for the current filetype)

:Neoformat jsbeautify

Or format a visual selection of code in a different filetype

Note: you must use a ! and pass the filetype of the selection

:Neoformat! python

You can also pass a formatter to use

:Neoformat! python yapf

Or perhaps run a formatter on save

augroup fmt
  autocmd!
  autocmd BufWritePre * undojoin | Neoformat
augroup END

The undojoin command will put changes made by Neoformat into the same undo-block with the latest preceding change. See Managing Undo History.

Install

The best way to install Neoformat is with your favorite plugin manager for Vim, such as vim-plug:

Plug 'sbdchd/neoformat'

Current Limitation(s)

If a formatter is either not configured to use stdin, or is not able to read from stdin, then buffer data will be written to a file in /tmp/neoformat/, where the formatter will then read from

Config [Optional]

Define custom formatters.

Options:

name	description	default	optional / required
`exe`	the name the formatter executable in the path	n/a	required
`args`	list of arguments	[]	optional
`replace`	overwrite the file, instead of updating the buffer	0	optional
`stdin`	send data to the stdin of the formatter	0	optional
`stderr`	capture stderr output from formatter	0	optional
`no_append`	do not append the `path` of the file to the formatter command, used when the `path` is in the middle of a command	0	optional
`env`	list of environment variable definitions to be prepended to the formatter command	[]	optional
`valid_exit_codes`	list of valid exit codes for formatters who do not respect common unix practices	[0]	optional
`try_node_exe`	attempt to find `exe` in a `node_modules/.bin` directory in the current working directory or one of its parents (requires setting `g:neoformat_try_node_exe`)	0	optional

Example:

let g:neoformat_python_autopep8 = {
            \ 'exe': 'autopep8',
            \ 'args': ['-s 4', '-E'],
            \ 'replace': 1, " replace the file, instead of updating buffer (default: 0)
            \ 'stdin': 1, " send data to stdin of formatter (default: 0)
            \ 'env': ["DEBUG=1"], " prepend environment variables to formatter command
            \ 'valid_exit_codes': [0, 23],
            \ 'no_append': 1,
            \ }

let g:neoformat_enabled_python = ['autopep8']

Configure enabled formatters.

let g:neoformat_enabled_python = ['autopep8', 'yapf', 'docformatter']

Have Neoformat use &formatprg as a formatter

let g:neoformat_try_formatprg = 1

Enable basic formatting when a filetype is not found. Disabled by default.

" Enable alignment
let g:neoformat_basic_format_align = 1

" Enable tab to spaces conversion
let g:neoformat_basic_format_retab = 1

" Enable trimmming of trailing whitespace
let g:neoformat_basic_format_trim = 1

Run all enabled formatters (by default Neoformat stops after the first formatter succeeds)

let g:neoformat_run_all_formatters = 1

Above options can be activated or deactivated per buffer. For example:

    " runs all formatters for current buffer without tab to spaces conversion
    let b:neoformat_run_all_formatters = 1
    let b:neoformat_basic_format_retab = 0

Have Neoformat only msg when there is an error

let g:neoformat_only_msg_on_error = 1

When debugging, you can enable either of following variables for extra logging.

let g:neoformat_verbose = 1 " only affects the verbosity of Neoformat
" Or
let &verbose            = 1 " also increases verbosity of the editor as a whole

Have Neoformat look for a formatter executable in the node_modules/.bin directory in the current working directory or one of its parents (only applies to formatters with try_node_exe set to 1):

let g:neoformat_try_node_exe = 1

Adding a New Formatter

Note: you should replace everything {{ }} accordingly

Create a file in autoload/neoformat/formatters/{{ filetype }}.vim if it does not already exist for your filetype.
Follow the following format

See Config above for options

function! neoformat#formatters#{{ filetype }}#enabled() abort
    return ['{{ formatter name }}', '{{ other formatter name for filetype }}']
endfunction

function! neoformat#formatters#{{ filetype }}#{{ formatter name }}() abort
    return {
        \ 'exe': '{{ formatter name }}',
        \ 'args': ['-s 4', '-q'],
        \ 'stdin': 1
        \ }
endfunction

function! neoformat#formatters#{{ filetype }}#{{ other formatter name }}() abort
  return {'exe': {{ other formatter name }}
endfunction

Managing Undo History

If you use an autocmd to run Neoformat on save, and you have your editor configured to save automatically on CursorHold then you might run into problems reverting changes. Pressing u will undo the last change made by Neoformat instead of the change that you made yourself - and then Neoformat will run again redoing the change that you just reverted. To avoid this problem you can run Neoformat with the Vim undojoin command to put changes made by Neoformat into the same undo-block with the preceding change. For example:

augroup fmt
  autocmd!
  autocmd BufWritePre * undojoin | Neoformat
augroup END

When undojoin is used this way pressing u will "skip over" the Neoformat changes - it will revert both the changes made by Neoformat and the change that caused Neoformat to be invoked.
