Creating functions like Lego blocks
I had a fun time making my own static-site generator for a blog, and I thought this could serve as a practical introduction to Functional Reactive Programming (FRP).
Introductions are hard, so I'm just gonna jump right into this.
Many times a script is written that needs extra/persistent configuration from the user. In most languages this is no big deal, you just import your json/yaml/toml parser and you're good to go. The common thing to do for many bash scripts that require configuration is to ask the user to put another actual bash script containing variable declarations in the file:
Bash is perhaps one of the hardest languages to learn how to script with, simply for the fact there's so much bad information out there. I'd like to share some tips and tricks I've learned in my few years of scripting.
It seems there's some confusion on why you might use functional programming methods like map/reduce/filter, and so I thought I'd write something to try and explain why I think they're useful and interesting.
I recently came across fzf, which is an interactive line filter. By default fzf will fuzzy search recursively through file names in the current directory, but it also filters through stdin.
