TxtStyle is a command line tool colorizing output of console programs.
It makes it easier to visually scan log files. Or it can be simply used
to make output prettier.
git clone git://github.com/armandino/TxtStyle.git
cd TxtStyle
Apply 'example' style to example.log
./txts -n example example.log
Color ifconfig output
ifconfig | ./txts -n ifconfig
Color calendar
cal 2012 | ./txts -n calendar
Color ps output
ps aux | txts -n ps
To install, execute the setup script in the TxtsStyle directory:
sudo python2 setup.py install
(Alternatively, simply put the txts script on the PATH)
TxtStyle reads styles from a conf file under user's home directory:
~/.txts.conf
There are some example styles defined out of the box. To define your own, add styles to the conf and reference them by name.
For example, add "mystyle":
[Style="mystyle"]
blue: index(0-6)
red: regex("foo")
green bold: regex("bar")
grey on-yellow: regex("baz")
TxtStyle works by styling lines of text using regular expressions
and/or string indexes. So index(0-6) highlights a substring of a line
and regex("pattern") highlights text matching the pattern.
Save the conf file with "mystyle" and run txts with
the -n (or --name) option:
echo "Styling foo, bar, and baz." | txts -n mystyle
TxtStyle configuration supports a small set of named color keys
(such as red, blue, yellow) and an extended set of numeric keys
(from 1 to 255). To print available keys use the -p option:
txts -p
Highlight text using the -r (or --regex) option. For example
echo "A Foo and a Bar" | txts -r "Foo|Bar"
will color both Foo and Bar in red. If you use the -r option
multiple times, each of the specified regexps will have a different
color, as in:
echo "A Foo and a Bar" | txts -r Foo -r Bar
TxtStyle does not apply styles if output is piped to another command.
To force color if the output is piped, use --color-always option:
ps aux | txts -n ps --color-always | less -R
Print basic help
txts -h
