Rex 1.0
Rex is a graphical javascript Regular Expression editor. It’s something I’ve had sitting around for a couple years and really helped me with data mining projects consisting of a big messy text documents. So i figured I’d post it in hopes it’ll be just as useful to others as it was for me.
I liken it to a graphical, javascript version of sed or awk.
Rex is released under GNU GPL. If you would like to download rex simply "View the Source" of the rex page and copy and paste. Also prototype.js is required.
TODO:
- add an ‘e’ (expression) flag so custom javascript can be executed on every match.
- add a ‘z’ flag to continue to apply the pattern until zero matches.
