Make::Cache::Hash 1.043

Make::Cache::Hash package contains dependency file functions and hashing.

SYNOPSIS

Make::Cache::Hash::clear_cache();
hash{tgt}{dep} = Make::Cache::Hash::dfile_read(filename=>fn);
my $digest = Make::Cache::Hash::hash(filenames=>[], text=>[]);

Make::Cache::Hash contains functions for reading and writing make.d files, and for doing MD5 hashes on files.

FUNCTIONS

dfile_read (filename=>in)

Read the specified filename. Return a hash reference, where the keys of the hash are the target (generated output) files, and the values are a hash of the dependent (required input) files. The filename itself is considered a output dependency.

hash

Return a MD5 hash on the specified list of filenames, and specified list of text. With the ignore_rcs parameter, which defaults as on, ignore any RCS/CVS/Perforce meta tags in the source.

clear_hash

Clear the internal cache used to accelerate the hash() function. Must be called anytime a file that has been hashed has changed.

newest

Return the mod time of the newest filename in the list of filenames passed. If any does not exist, return undef.
