NAME

Devel::Depend::Cl - Extract dependency trees from c files

DESCRIPTION

Extract dependency trees from c files. See the Devel::Depend::Cpp manpage for more an example.

MEMBER FUNCTIONS

Depend

Depend calls cl (the microsoft C compiler) to extract included files.

Returns

• Success flag
• A reference to a hash where the included files are sorted perl level. A file can appear at different levels
• A reference to a hash with one file per entry
• A reference to a hash representing an include tree
• A string containing an error message, if any

Arguments

• the name of the 'cl' binary to use. undef to use the first 'cl' in your path
• The name of the file to depend
• A string to be passed to cpp, ex: '-DDEBUG'
• A boolean indicating if the system include files should be included in the result
• a sub reference to be called everytime a node is added (see depender.pl for an example)
• A boolean indicating if the output of cpp should be dumped on the screen

This sub is a wrapper around RunAndParse.

RunAndParse

This sub runs a, preprocessor, command passed as an argument and parses its output. The output is expected to follow the cl output format. This sub allows finer control of the preprocessing. Try Depend first.

CollapsePath

Removes '.' and '..' from a path.

EXPORT

$PreprocessorDepend, a scalar containing a reference to the Depend sub.

DEPENDENCIES

cpp.
