8.6. AutoSplit
Splits a program or module into files that the AutoLoader can handle. It can be called from a program or from the command line:
# From a program use AutoSplit; autosplit_modules(@ARGV) # From the command line perl -MAutoSplit -e 'autosplit(FILE, DIR, KEEP, CHECK, MODTIME)' ... # Another interface perl -MAutoSplit -e 'autosplit_lib_modules(@ARGV)' ...
AutoSplit is used by MakeMaker as well as by the standard Perl libraries. It operates on a file, splitting off subroutines that come after the _ _END_ _ marker and storing them as described above for AutoLoader, creating any necessary directories along the way. AutoSplit has two functions.
| autosplit |
autosplit (file, dir, keep, check, modtime)
Splits the module into files. Each file is given the name of the subroutine it contains, with .al appended. autosplit also creates the file autosplit.ix, which serves as both a forward declaration of all package routines and as a timestamp showing when the hierarchy was last updated. Takes the following arguments:
- file
- Filename of program or module to be split.
- dir
- Name of directory hierarchy in which to store the split files.
- keep
- If false, preexisting .al files in the auto directory that are no longer part of the module are deleted.
- check
- If true, checks to be sure the module being split includes a use AutoLoader statement. If the statement is missing, autosplit doesn't process the module.
- modtime
- If true, splits the module only if it is newer than autosplit.ix.
| autosplit_lib_modules |
autosplit_lib_modules (@ARGV)
Takes a list of modules that are assumed to be in a lib subdirectory of the current directory, processes them as described above for autosplit, and stores the resulting file in the directory lib/auto. Used in building Perl.
