DESCRIPTION

txt2regex is a Regular Expression "wizard", all written with bash2 builtins, that converts
human sentences to regexes.

With a simple interactive interface, you just answer to questions and build your own regex
for a large variety of programs, like awk, emacs, grep, perl, php, procmail, python, sed
and vim. There are more than 20 supported programs.

It's bash so download and run, no compilation needed.

Please visit the program homepage at http://txt2regex.sf.net.

OPTIONS

--all works with all registered programs

--help prints the help message and quit

--history <value>
prints to STDOUT a regex from a history data

--make <target>
prints a ready regex for a common pattern

--nocolor
self-explanatory

--prog <p1,p2,...>
choose which programs to use (separated by commas)

--showinfo <program>
prints regex info about the program

--showmeta
prints a complete metachar table for all programs

--version
prints the program version and quit

--whitebg
colors adjusted to white background terminals

By default, all options are turned OFF. Just call it with no options to launch the default
interactive interface.

DETAILS

--all is cool but requires lots of lines (~35)

--nocolor is strong, so it kills --whitebg

--showmeta rules, try it

--showinfo uses reverse video output, --nocolor turns it off

--history is getting useful, stay tunned

--make is a remedy for headaches

--prog is nice to use your favorite programs, mix it with --make and --history
