Bash Infinity is a modern standard library / framework / boilerplate for Bash The aim of Bash Infinity is to maximize readability of bash scripts, minimize the amount of code repeat and create a central repository for well-written, and a well-tested standard library for bash.
Bash++: Bash with classes Bash++ is a superset of Bash that adds support for object-oriented programming. Almost all Bash code is valid Bash++ code. The Bash++ extension for Visual Studio Code provides basic syntax highlighting.

Modernish is a library for shell script programming which provides features like safer variable and command expansion, new language constructs for loop iteration, and much more. Modernish programs are shell programs; the new constructs are mixed with shell syntax so that the programmer can take advantage of the best of both.
The Shell Toolkit, or shtk for short, is an application toolkit for programmers writing POSIX-compliant shell scripts. shtk provides a collection of reusable modules that work on a wide variety of operating systems and shell interpreters. These modules are all ready to be used by calling the provided shtk_import primitive and "compiling" the shell scripts into their final form using the shtk(1) utility. shtk is known to be compatible with at least bash, dash, pdksh and zsh, and continuous integration tests prove this to be the case.

Awkl (short for Awk's well-kempt library) is a library that attempts to bring modules present in other languages' standard libraries to gawk. The library makes use of gawk's namespaces (available since version 5.0) and other gawk-specific features, but we reckon a good part of the library could be adapted to be awk-agnostic (maybe with a hypothetical transpiler)
https://codeberg.org/tplasdio/gawk-libc
A gawk extension that attempts to bind C functions leanly and idiomatically to gawk. Currently we've bind some useful libraries from POSIX, but we will try to support 3 distributions: libc, posix, glibc.
