Escape Color!
A command line tool that prints a string containing the escape sequence that produces ANSI effects and colors. It can also print the escaped string.
It is posible to escape a sequence, then print something else with other tool and the escaped effects will be aply to the output of that other tool, unless that tool manage its own effects.
I made escolor to make it easier to obtain ANSI color escape sequences. I don't intend escolor to be a morer
complex tool than that.
It is also an experiment in how to get a command line tool to capture options in the typical Linux tool style.
It may not be the most efficient approach, but it is one that fits in a few lines of code in a single script.
For that reason I don't use argparse, getopt or the more limited getopts. This allowed me to interpret the
order of the arguments to make sequential changes to the output, where a normal argument is affected only by the
previous options and not the following ones.
This repository provides a Bash version and a Python version. Both work exactly the same for all examples in the help message.
A string with consecutive backslashes will have different results depending on the version you choose, but any string can be printed with both by adding more or fewer backslashes.
