A larger annoyance is that org-lint doesn't actually know what languages
|
||||
org-babel should recognise, with Doom's lazy loading system. Since the list of
|
||||
languages should really only change when packages are added/removed, we might as
|
||||
well statically determine a list of all org-babel languages at configuration
|
||||
generation time.

This increases the tangle time by about 10--20%, but I think it's worth it to be
|
||||
extra thorough. If this really becomes a pain, we can always think about doing
|
||||
some sort of cache file based on the load-path/packages installed.
