VSCode regex replace using regex group

Question

I want to replace map["someKey"] as double by (map["someKey"] as num).toDouble(), but I just can't get the regex working correctly. Can someone who knows more about regex tell me what to put in Find and Replace in VSCode? I've tried ([a-zA-Z0-9]*) as double and replaced this by ($1 as num).toDouble(), but this doesn't work.

Answer 1

Use

(\w+\["[^"]+"\]) as double

See regex proof. Replace with ($1 as num).toDouble().
