the web assembly system interface allows many command-line utilities to run anywhere, including plan 9! it's like java but simpler, at the cost of not supporting some stuff like networking.

runtime ¶
wazero is a zero dependency wasi runtime written in go, it mostly works in 9front
pre-compiled blobs ¶
python3 ¶
brettcannon has a build of python 3.12.2. running files works, however
time.sleep() errors out due to wazero missing this functionality,
and there appears to be some platform-specific bug with the repl that
causes it to hang on plan 9.
ugh, isn't the whole point of wasm to not have platform-specific bugs!?

php-cgi ¶
vmware-labs' webassembly-language-runtimes has a build of php 8.2.6 in addition to python and ruby.
it's a bit out of date though, the latest build in their releases is
from . since they're seemingly in
the process of migrating the repository to some other organization,
who still has not touched it as of
the wasmedge variants seem to not be supported by wazero, looks like
we're stuck with php-cgi.
