TxtStyle

TxtStyle is a command line tool for colorizing output of console programs. Its main goal is to assist humans in reading log files by highlighting text in various colors using custom rules. Or it can simply be used to make output of console programs prettier.

Requirements

• Latest version 1.1.2 requires Python 3.7+

Install

Using package installer

pip install TxtStyle

From sources

git clone https://github.com/armandino/TxtStyle.git
cd TxtStyle
sudo python setup.py install

Try it out

Apply 'example' style to example.log

wget https://raw.githubusercontent.com/armandino/TxtStyle/master/example.log
txts -n example example.log

Define your own styles

TxtStyle reads styles from a config file under user's home directory:

~/.txts.conf

A default config is generated by the installer. It contains some styles provided as an example. To define your own, add styles to the config and reference them by name.

For example, to 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. 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

Other usage examples

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 help

txts -h
