For better or worse, PHP code often includes both HTML and Javascript. Getting Vim to indent it all correctly can be tricky.
My .vimrc specifies that a tab should always be two spaces:
set tabstop=2
set softtabstop=2
set shiftwidth=2
This indent file does a good job with indenting mixed PHP and HTML and uses 2 spaces for both, but for some reason, it indents embedded Javascript with 4 spaces. The code snippet below gets auto-indented as shown.
<?PHP
if (false) {
$foo = 'foo';
}
?>
<html>
<head>
<script type="text/javascript">
function(){
if (false) {
// Four spaces!?
var foo = 'foo';
}
}
</script>
</head>
</html>
If I create a separate javascript file, it indents as it should, like so:
if (false) {
var foo = 'foo';
}
I'm not sure why Vim indents the Javascript in the first example as it does. Is there a way to ask Vim "what syntax or indentation are you using on this specific line?"
/syntax/javascript.vimcurrently. I do have aindent/javascript, but that just decides when to indent or unindent, not how many spaces to use for an indent. And, as I said, a separate JS file gets indented with my default of two spaces. – Nathan Long Aug 31 '11 at 19:06
