I found a utility that might do, PowerRegex. But they want about $150
for it, there are hints you have to rebuy it for every bug release.
It seems GUI focused and DEBE.

>2. write one

Let's say I do  this and offer it open  source, free.

I have written  a  number student regex projects.  Implementing them
all  would be quite a hunk of work.

I am trying to think of a minimalist start, enough to solve by current
problem, still be useful to others, and open to gradual  evolution.

I thought it would be script driven.
I  need a format for a script that
1. describes which files to apply it to.
2. supplies pairs of search/replace regexes
3. allows search-only
4. deals with regexes that end in spaces.   Presume you can trust
editors to leave them in peace.

It would need ability to suppress replace, just search.  It would
allow you run single step or run to end of file, or  end of dir or
everything.

Regex itself handles binary.

Later add some way of dealing \uxxxx in regexes. handle non-regex,
case-insensitive/case-sensitive without having to embed commands in
regexes, negative wildcards. GUI to edit script.
HTML module where space, spaces, tab, nl all match space in searches.
proofread composer/proofreader that uses colour to let you know which
chars are being used as literal/commands. anonymous one-shot scripts.
ability to  touch up searched text in middle of search with minimal
text editor or launch to favourite  with line number/offset. Undo.

Any ideas on ideal format for an extensible script file?
