How To Use A Capture Group With Gulp-replace?

gulp-replace 0.5.4 Current via gulp and rev: Goal: Copy

for $1 to "work" the same way as $& (backreference to the whole match value).

Solution 2:

Your can use a callback as the second parameter in gulp-replace. The function was loop over each capture group. Here's an example where I am converting camelCase variables to css notation

.pipe(replace(/([A-Z])/g, function(match){
  return'-'+match.toLowerCase()
}))

{camelCase1: 1, camelCase2: 2}

Becomes camel-case1 and case-case2
