command_help VS mpd_what

I use a lot of CLI tools, but haven't written many for myself. Mostly, aliases/functions and some scripts in Bash/Python.

Extract details for command options from man/help: https://github.com/learnbyexample/command_help/blob/master/c...

cut-like syntax for field manipulations with regexp, negative indexing, etc: https://github.com/learnbyexample/regexp-cut/blob/main/rcut

simple calculator using python syntax: https://learnbyexample.github.io/practice_python_projects/ca...

I wrote a Linux CLI tool [0] that parses the man/help pages to extract option details. Works most of the time for me, but there are plenty of corner cases that don't work.

https://github.com/learnbyexample/command_help to extract help text from builtin commands and man pages, ex:

https://github.com/learnbyexample/command_help is big enough to warrant a repo, examples, limitations, etc. I had a list of todo items to improve the script, but after years of usage, I'm fine with the limitations since I rarely encounter them. This helps me to extract documentation of particular options, here's an example:

I wrote one a few years back (https://github.com/learnbyexample/command_help). It has a few corner case issues, but works most of the time for me and supports multiple options to be retrieved.

I particularly wanted to lookup documentation for command options from my terminal (instead of the website), so wrote a script for it: https://github.com/learnbyexample/command_help ... Have a long pending todo list, but despite the issues, the tool is good enough for my needs.

When I start a project, I usually try to write the programs incrementally. Say I need to iterate over files from a directory. I will make sure that portion is working (usually with print() statements), then add another feature — say file reading and test that and so on. This reduces the burden of testing a large program at once at the end. And depending upon the nature of the program, I'll add a few sanity tests at the end. For example, for my command_help project, I copy pasted a few test runs of the program with different options and arguments into a separate file and wrote a program to perform these tests programmatically whenever the source code is modified.

mpd_what is a python script I developed to show the album art, artist, album, and song for music I am listening to with mpd, including (some) internet radio. I made this because I didn't want to have to download and install all the different radio apps for my phone just to maybe see the coverart and info of what they're playing. This script works to enhance one of my other utilities, which is:

Shameless plug: I wrote a script to grab album art, title, track, and album for music being played on mpd, even internet radio. Check it out at https://github.com/charmparticle/mpd_what
