odoc
odoc is a documentation generator for OCaml. It reads doc comments,
delimited with (** ... *), and outputs HTML. See example output at
docs.mirage.io.
Text inside doc comments is marked up in ocamldoc syntax:
val compare : string -> string -> int
(** [compare s1 s2] compares [s1] and [s2] in {e lexicographic} order. The
result is negative if [s1] precedes [s2], positive if [s1] follows [s2],
and zero if [s1] and [s2] are equal. *)The syntax reference is here. There is also an explanation of how to attach comments to specific types, values, and other elements in your program.
odoc's main advantage over ocamldoc is an accurate cross-referencer, which handles the complexity of the OCaml module system. odoc also offers a good opportunity to improve HTML output compared to ocamldoc, but this is very much a work in progress :)
Installing and usage
opam install odoc
The easiest way to use odoc right now is by having Dune drive it. This command should work in most Dune projects out of the box:
dune build @doc
The generated docs can then be found locally at
./_build/default/_doc/_html/index.html.
