How do you use vim's quickfix feature?
jslint, vim
Solution
There are a lot of commands for quickfix as you have said, but I tend to find I only use a small subset of them:
:copen " Open the quickfix window
:ccl " Close it
:cw " Open it if there are "errors", close it otherwise (some people prefer this)
:cn " Go to the next error in the window
:cp " Go to the previous error in the window
:cnf " Go to the first error in the next file
:.cc " Go to error under cursor (if cursor is in quickfix window)
I tend to use this with `:make` and `:vimgrep`, so I can't comment on the Javascript lint checker, but this should give you something to get started.
Regarding the general use of JavascriptLint, I'm not a javascript programmer, but it looks like the script exposes a function called "JavascriptLint", so if you want to call it manually, you can use `:call JavascriptLint()`. However, it works on the disk copy of the file, so it'll have to be saved first. If (and only if) the command line `jsl` works on html files, you should be able to use `:call JavascriptLint()` on an html file to check the internal javascript. You could also do:
autocmd BufWritePost,FileWritePost *.html call JavascriptLint()
to automate it. If `jsl` doesn't support html files, then (short of patching the application or asking the author to change it), it's probably a lost cause...
Problem
I'm a pretty new Vim user and I've found that its learning curve is quite steep (at least for me). I just installed this vim script for JavaScriptLint error checking, which shows errors in vim's quickfix window once I save a buffer. However, I don't know what to do next.. How do I 'scroll' through all the errors? How do I close the quickfix 'window'? How do I get it to check for errors after I've made changes to my code? I've looked at the vim quickfix docs but the amount of commands are overwhelming and I can't seem to find what I want. Any help would be appreciated. A side question: is there any way to have javascriptlint check for js errors for code residing in a .html file?
