txt2regex
TXT2REGEX(1) General Commands Manual TXT2REGEX(1)
NAME
txt2regex - a Regular Expression Wizard, written with bash2 builtins
SYNOPSIS
txt2regex
txt2regex --nocolor|--whitebg
txt2regex --all|--prog <p1,p2,...,pN>
txt2regex --showmeta|--showinfo <program>
txt2regex --make <target>
txt2regex --history <value>
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
EXAMPLES
Calling the program on the default interactive interface
$ txt2regex
Calling the program on a white terminal
$ xterm -fg black -bg white ; txt2regex --whitebg
Getting information
$ txt2regex --showmeta
Getting specific information
$ txt2regex --showinfo sed

$ txt2regex --make number3 --prog perl
$ txt2regex --make date2 --all
