Document Generator for Lean 4
doc-gen4 is the easiest to use via its custom Lake facet, in order
to do this you have to add it to your lakefile.lean like this:
meta if get_config? env = some "dev" then -- dev is so not everyone has to build it
require «doc-gen4» from git "https://github.com/leanprover/doc-gen4" @ "main"
Then you can generate documentation for an entire library using:
lake -Kenv=dev build Test:docs
If you have multiple libraries you want to generate documentation for the recommended way right now is to run it for each library.
