One of the best ways to support ASPL is by writing a project in it. You may port an already existing tool, develop something innovative and new, or even rewrite your own applications in ASPL.
Such projects are essential for assessing ASPL's usability across various fields of computer science, catching and fixing bugs, and adding new features. It also just massively helps in making ASPL more known and popular.
You can, of course, also directly contribute to ASPL's sourcecode (and the surrounding stuff) here on Github.
The best way to get started is probably just looking around at the files and folders; here's a quick overview of how the code is structured:
The ASPL standard library is mostly written in ASPL itself (plus some C for low-level code) and located in the stdlib folder.
Due to the special design of the ASPL monorepo, the compiler (along with some related components such as the parser) is actually part of the standard library and thus also self-hosted.
Please read the REAMDE of the stdlib/aspl folder for more information.
The runtime and the AIL interpreter are written in C; they are currently located at stdlib/aspl/compiler/backend/stringcode/c/template.c and runtime/ailinterpreter respectively.
