parameter complete
indicates if we must print complete signatures or just sig end. Default is false.

val string_of_class_type : ?complete:bool -> Types.class_type -> string

This function returns a string representing a Types.class_type.

parameter complete
indicates if we must print complete signatures or just object end. Default is false.

Get a string from a text.

val string_of_info : info -> string

Get a string from an info structure.

val errors : int ref

Increment this counter when an error is encountered. The ocamldoc tool will print the number of errors encountered exit with code 1 if this number is greater than 0.

info_of_string s parses the given string like a regular ocamldoc comment and return an Odoc_info.info structure.

returns
an empty structure if there was a syntax error. TODO: change this

val info_of_comment_file : Module.t_module list -> string -> info

info_of_comment_file file parses the given file and return an Odoc_info.info structure. The content of the file must have the same syntax as the content of a special comment. The given module list is used for cross reference.

raises Failure

val remove_ending_newline : string -> string

remove_ending_newline s returns s without the optional ending newline.

module Search : sig ... end

Research in elements
