Ruby -> rbenv (not rock, but RVM SUCK TOO HARD)
ack -> ignore .gitignore by default + full path displa
GPP -> A generic preprocessor
rlwrap -> run command via
rlwrap sbcl -> no more troubles!
GNU Poke -> Simple binary editor
Cockpit -> web management
vim like tools
Meson Build -> Force you to do things as the meson way or don't use
Gradle -> A build system that cost same RAM as a full-flagged IDE
Plotly -> You need a login to use it?
doctest -> https://github.com/onqtam/doctest fmt -> ez to use pythonic lib which also support C++20 format (it may be replaced by format eventually)
Catch2 -> abandoning their promise and keep bloating (if they are bloating, why not use Google Test?)
