It is well known that a manual javascript formatting is very boring. Someone wrote a beautiful tool - js-beautify, but it never was properly integrated with vim. This one is the one I use for last 2 years.
##How this works
- Press a <leader> ff( ,ff if your leader key is a comma) to format your javascript file when in a normal mode.
- Press a Ctrl-f inside an insert mode to format your javascript while you are editing it. The cursor position is kept so you can continue typing the code
- Press an 'U' to cancel this formatting if something goes wrong and you are not happy with formatting
##What do I need to have this working?
- Nodejs should be installed.
- Install this plugin any way you like (Pathogen / Vundle / Janus)
##Why is this a great plugin?
- Marks and your current cursor position are kept during formatting. Here is how I achieve this: during the js-beautify preprocessing number of non blank characters is not changed, thus I associate a mark with the number of non blank character before it and later put the cursor back.
- No need for extra configuration! expandtab and softtabstop already provides me an info how you would like to format your javascript. TODO: You can always add an extra option s:formatjs_keep_blank_lines
- Works without saving a file. Works in the indent mode.
##TODO:
-
Borrow css-beautify and html-beautify
-
Allow new lines inside () and [] for string parameters, because currently
[
'a',
'b',
'c',
'd'
]
is always converted to the ['a','b','c','d'] . Sometimes it is important to
have word wraps here
