Basic module stuff

module Empty : sig ... end

A plain, empty module

module type Empty = sig ... end

An ambiguous, misnamed module type

module type MissingComment = sig ... end

An ambiguous, misnamed module type

Level 9000
module EmptyAlias = Empty

A plain module alias of Empty

EmptySig

module type EmptySig = sig ... end

A plain, empty module signature

module type EmptySigAlias = EmptySig

A plain, empty module signature alias of

A plain module of a signature of EmptySig (reference)

A plain module with an alias signature

module One : sig ... end
module type SigForMod = sig ... end

There's a signature in a module in this signature.

module type SuperSig = sig ... end

For a good time, see subSig or subSig or SuperSig.EmptySig. Section Level 9000 is also interesting. EmptySig is a general reference but EmptySig is the section and EmptySig is the module signature.

module Buffer : sig ... end

Buffer.t

Some text before exception title.

Basic exception stuff

After exception title.

exception Kaboom of unit

Unary exception constructor

exception Kablam of unit * unit

Binary exception constructor

exception Kapow of unit * unit

Unary exception constructor over binary tuple

exception EmptySig

EmptySig is general but EmptySig is a module and EmptySig is this exception.

exception EmptySigAlias

EmptySigAlias is this exception.

Basic type and value stuff with advanced doc comments

type ('a, 'b) a_function = 'a -> 'b

a_function is general but a_function is this type and a_function is the value below.

val a_function : x:int -> int

This is a_function with param and return type.

  • parameter x

    the x coordinate

  • returns

    the y coordinate

val fun_fun_fun : ((int, int) a_function, (unit, unit) a_function) a_function
val fun_maybe : ?yes:unit -> unit -> int
val not_found : unit -> unit
  • raises Not_found

    That's all it does

val ocaml_org : string
val some_file : string
  • see some_file

    The file called some_file

val some_doc : string
  • see some_doc

    The document called some_doc

val since_mesozoic : unit

This value was introduced in the Mesozoic era.

  • since mesozoic
val changing : unit

This value has had changes in 1.0.0, 1.1.0, and 1.2.0.

  • before 1.0.0

    before 1.0.0

  • before 1.1.0

    before 1.1.0

  • version 1.2.0
val with_foo : unit

This value has a custom tag foo. @foo the body of the custom foo tag

Trying the {!modules: ...} command.

With ocamldoc, toplevel units will be linked and documented, while submodules will behave as simple references.

With odoc, everything should be resolved (and linked) but only toplevel units will be documented.

Weirder usages involving module types

  • IncludeInclude1.IncludeInclude2
  • Dep4.T
  • A.Q

Playing with @canonical paths

module CanonicalTest : sig ... end
val test : 'a CanonicalTest.Base__.List.t -> unit

Some ref to CanonicalTest.Base__Tests.C.t and CanonicalTest.Base__Tests.L.id. But also to CanonicalTest.Base__.List and CanonicalTest.Base__.List.t

Aliases again

module Aliases : sig ... end

Let's imitate jst's layout.

Section title splicing

I can refer to

But also to things in submodules:

  • {!section:SuperSig.SubSigA.subSig} : subSig
  • {!Aliases.incl} : incl

And just to make sure we do not mess up:

  • {{!section:indexmodules}A} : A
  • {{!aliases}B} : B
  • {{!section:SuperSig.SubSigA.subSig}C} : C
  • {{!Aliases.incl}D} : D
