Cmt_format (reference.merlin-lib.merlin-lib.ocaml_typing.Ocaml_typing.Cmt

The layout of a cmt file is as follows: <cmt> := {<cmi>} <cmt magic> {cmt infos} {<source info>} where <cmi> is the cmi file format: <cmi> := <cmi magic> <cmi info>. More precisely, the optional <cmi> part must be present if and only if the file is:

a cmti, or
a cmt, for a ml file which has no corresponding mli (hence no corresponding cmti).

Thus, we provide a common reading function for cmi and cmt(i) files which returns an option for each of the three parts: cmi info, cmt info, source info.

Sourceval read : string -> Cmi_format.cmi_infos option * cmt_infos option

read filename opens filename, and extract both the cmi_infos, if it exists, and the cmt_infos, if it exists. Thus, it can be used with .cmi, .cmt and .cmti files.

.cmti files always contain a cmi_infos at the beginning. .cmt files only contain a cmi_infos at the beginning if there is no associated .cmti file.
