Hi guys,

I have this Javascript regex to prefix CSS rules to a given ID:

css = css.replace(/([,|\}][\s$]*)([\.#]?-?[_a-zA-Z]+[_a-zA-Z0-9-]*)/g, "$1" + "#myDiv" + " $2��);

/([,|}][\s$]*)([.#]?-?[_a-zA-Z]+[_a-zA-Z0-9\-]*)

Thanks Max,

That allows me to create the regex correctly (well at least it doesn't fail). But how can I now make the translate, for example, from this input:

' .aClass { color: red ; } '

to

'#myDiv .aClass { color: red; }'

That's a bit more work in Pharo, unfortunately. You'll have to access capture groups explicitly:

matcher := '(\d)(\d_\d)' asRegex.

matcher matches: '12_3'.

matcher subexpression: 1. "'12_3'"

matcher subexpression: 2. "'1'"

matcher subexpression: 3 "'2_3'"

Max

Thanks!

HTH,
Max

I am trying to make this work on Pharo (and then I will need in GemStone) but I am getting errors while trying to create the regex itself. I am very far from being a regex expert (I got that regex from StackOverflow). Any help is appreciated.

Cheers,
