Starlark is a Python-ish subset intended for declarative-looking-but-still-procedural software configuration management in Bazel and Buck2. GDScript is their own take for the GODOT game engine. It looks like Python, but it's different. There are many usability advantages, like learning curve, by modeling off a commonly used language rather than dreaming up a completely new one. Here's a list of Python-like languages: https://blog.matt-rickard.com/p/the-python-family-of-languag... Starlark lang spec: https://github.com/bazelbuild/starlark/blob/master/spec.md Google implementations: https://github.com/google/starlark-go/ https://github.com/bazelbuild/bazel/tree/master/src/main/jav...

st... These are in the embeddable languages category like Lua and dialects of other languages with implementations such as mruby, daScript, emacs LISP, and ECL. And there were game-specific ones like QuakeC and Squirrel. Those were usually in the past because other embedded languages weren't available, but now hundreds of games use/d Lua because it doesn't make sense to build a language and runtime from scratch in most cases. Scriptability (or format documentation at least in the case of Doom-engine games) is key to implementing mods officially instead of as invasive game hacks like Super Dune 2.

One thing you might be missing is that this is Buck2. Buck (https://github.com/facebook/buck) has been open sourced for nearly 10 years now. The lore I've heard is that former Googlers went to Facebook, built Buck based on Blaze, and Facebook open sourced that before Google open sourced Blaze (as Bazel). The first pull to the Buck github repo was on May 8, 2013 (https://github.com/facebook/buck/pulls?q=is%3Apr+sort%3Acrea...). The first to Bazel was Sep 30, 2014 (https://github.com/bazelbuild/bazel/pulls?q=is%3Apr+sort%3Ac...).

I've also struggled with the C++ coverage support in Bazel. It looks unloved since around 2018. The most useful leads I've found so far are: * The design doc for the (abandoned?) coverage framework [1] * A prototype of GCOVR support [2] * Comment on getting llvm-profdata working [3] [1] https://docs.google.com/document/d/1-ZWHF-Q-qCKf19ik-t33ie58...

> "yeah this was written for a Google project, that other use case didn't apply to our project" Not only is that a very narrow set of use cases (Read: they only deploy statically linked binaries on mostly unix-y environments), Even the fixes for those very basic use cases take for ever. Eg. This 7 year old issue is still open: https://github.com/bazelbuild/bazel/issues/1920 . To be able to create a statically linked library, we had to use: https://github.com/hotg-ai/librunecoral/blob/master/runecora... . Had to use some weird hack to build shared libraries too. Overall, it was just annoying.
