Readme
Search CSS (and CSS-like) strings, with sensitivity to whether matches occur inside strings, comments, and functions.
var styleSearch = require('style-search');
styleSearch(options, callback);
By default, the search ignores strings, comments, and function names. You can use the options to change this behavior or introduce other restrictions. That is what makes this module more useful for many searches than indexOf()
or a RegExp
.
However, if you need more detailed parsing, you should consider using the real parsers PostCSS, postcss-selector-parser
, and postcss-value-parser
.
/* Here is some pink */
a { color: pink; }
a::before { content: "pink" }
b { color: shadesOfPink(7); }
styleSearch({
source: theCssStringAbove,
target: "pink",
}, function(match, count) {
/* Only the "pink" in `color: pink` will be
reported as a match */
});
For every match found your callback
is invoked. It is passed two arguments:
match
object with the following properties:
startIndex
: where the match beginsendIndex
: where the match endstarget
: what got matched (useful if your target
option is an array instead of a single string)insideFunctionArguments
: whether the match is inside a function — this includes the parentheses around the argumentsinsideComment
: whether the match is inside a commentinsideString
: whether the match is inside a stringBelow you'll see that syntax feature options all accept three keywords: "skip"
, "check"
, "only"
. An error will be thrown if you use "only"
more than once.
