modulize s capitalizes the first letter of s.

normalize s uncapitalizes the first letter of s.

modname_from_source filename is modulize stem where stem is the basename of the filename filename stripped from all its extensions. For instance, modname_from_source "/pa.th/x.ml.pp" is "X".

is_unit_name ~strict name is true only if name can be used as a valid module name.

Metadata for a compilation unit:

• the module name associated to the unit
• the filename prefix (dirname + basename with all extensions stripped) for compilation artifacts
• the input source file For instance, when calling ocamlopt dir/x.mli -o target/y.cmi,
• the input source file is dir/x.mli
• the module name is Y
• the prefix is target/y

source_file u is the source file of u.

prefix u is the filename prefix of the unit.

modname u or artifact_modname a is the module name of the unit or compilation artifact.

check_unit_name u prints a warning if the derived module name modname u should not be used as a module name as specified by is_unit_name ~strict:true.

make ~check ~source_file prefix associates both the source_file and the module name modname_from_source target_prefix to the prefix filesystem path prefix.

If check_modname=true, this function emits a warning if the derived module name is not valid according to check_unit_name.

Those functions derive a specific artifact metadata from an unit metadata.

The functions below change the type of an artifact by updating the extension of its filename. Those functions purposefully do not cover all artifact kinds because we want to track which artifacts are assumed to be bundled together.

Beware that companion_cmi a strips all extensions from the filename of a before adding the ".cmi" suffix contrarily to the other functions which only remove the rightmost extension. In other words, the companion cmi of a file something.d.cmo is something.cmi and not something.d.cmi.

mli_from_source u is the interface source filename associated to the unit u. The actual suffix depends on Config.interface_suffix.

mli_from_artifact t is the name of the interface source file derived from the artifact t. This variant is necessary when handling artifacts derived from an unknown source files (e.g. packed modules).

Check if the artifact is a cmi

find_normalized_cmi u finds in the load_path a file matching the module name modname u.

• raises Not_found

  if no such cmi exists
