I'm looking for an online utility that will prettify and add explanatory comments to a regular expression. Does one exist?
RegexBuddy - Free download and software reviews - CNET Download.
All modes after the minus sign will be turned off. E.g. (? i-sm) turns on case insensitivity, and turns off both single-line mode and multi-line mode. Not all regex flavors support this.
The software of regex analysis decomposes a regular expression in order to find each component (characters, pattern, matches) and describe its meaning. The analysis is based on a cut of the pattern matching expression. Example: /\d{2,5}/ correspond to \d (digit) {2,5} between 2 and 5 times.
I like the online tool: http://regexr.com
When you hover over the regular expression you will get an explanation of that part.
For what it's worth, I also like:
Both are free to use.
