vim-flow

A vim plugin for Flow.

  • Adds completions to omnifunc
  • Checks JavaScript files for type errors on save

Requirements

  • Requires Flow to be installed and available on your path
  • Requires the project to be initialised with flow init
  • Requires JavaScript files to be marked with /* @flow */ or /* @flow weak */ at the top

Installation

Pathogen

cd ~/.vim/bundle
git clone git://github.com/flowtype/vim-flow.git

NeoBundle

Add this to your ~/.vimrc

  NeoBundleLazy 'flowtype/vim-flow', {
            \ 'autoload': {
            \     'filetypes': 'javascript'
            \ }}

With Flow build step, using flow-bin

  NeoBundleLazy 'flowtype/vim-flow', {
            \ 'autoload': {
            \     'filetypes': 'javascript'
            \ },
            \ 'build': {
            \     'mac': 'npm install -g flow-bin',
            \     'unix': 'npm install -g flow-bin'
            \ }}

Usage

Unless disabled manually, vim-flow will check JavaScript and JSX files on save.

Commands

FlowMake

Triggers a type check for the current file.

FlowToggle

Turns automatic checks on save on or off.

FlowType

Display the type of the variable under the cursor.

FlowJumpToDef

Jump to the definition of the variable under the cursor.

Configuration

g:flow#autoclose

If this is set to 1, the quickfix window will not be opened when there are no errors, and will be automatically closed when previous errors are cleared.

Default is 0.

g:flow#enable

Typechecking is done automatically on :w if set to 1.

To disable this, set to 0 in your ~/.vimrc, like so:

let g:flow#enable = 0

Default is 1.

g:flow#errjmp

Jump to errors after typechecking if set to 1.

Default is 0.

g:flow#flowpath

Leave this as default to use the flow executable defined on your path. To use a custom flow executable, set this like so:

let g:flow#flowpath = /your/flow-path/flow

g:flow#omnifunc

By default omnifunc will be set to provide omni completion. To disable it (prevent overwriting an existed omnifunc), set this value to 0:

let g:flow#omnifunc = 0

g:flow#timeout

By default timeout will be set to 2 seconds. If you are working on a larger codebase, you may want to increase this to avoid errors when Flow initializes.

let g:flow#timeout = 4

g:flow#qfsize

Leave this as default to let the plugin decide on the quickfix window size.

g:flow#showquickfix

By default, results are shown in a quickfix window. Setting this to 0 will stop the window from being shown. This is useful if you want to use vim-flow for the omnicomplete functionality, but are already using something like ale.

let g:flow#showquickfix = 0
