> So, since many mediawiki systems use lua, does this mean that you can code in Lisp (or Fennel), transpile to Lua, and then run the code as a module in a media wiki system?
Yes, easily.
With a little bit more work you could load the Fennel compiler up server-side so it could do the compilation for you and support Fennel "natively". I have done a similar process with TIC-80 despite knowing very little C: https://github.com/nesbox/TIC-80/pull/597
> What about Common Lisp libraries? would they be transpiled too?
No, Common Lisp is a completely different language with little in common with Fennel.
