I generate a lot of Unix tools, mostly in gawk wrapped in sh (Bourne shell), with some other tools like cut, sed, etc.

Things like hex/bin formatting and generation, logic analyzer address trace mapping, etc. Once in a while it involves floating point, not often, though.

Gawk is somewhat like C but interpreted, so it's easy to knock off a quick script, or a hard one (several pages of gawk for a tool to combine a logic analyzer log with address maps and program binaries), and to test it along the way.

It's been a long time since I've used Cygwin (a free Unix shell environment that runs in its own process under Windows), but apparently it now comes with gawk included.
