# _perl_modules - zsh completion function
#
# Adam Spiers <adam@spiers.net>
#
# Calculate all installed Perl modules. The result is cached
# for future use.
#
# Options:
#
# -t[types]: indicate file types; currently the only one is -tP,
# to include .pod files as well as modules.
#
# --perl-hierarchy=...: restrict results to modules under this hierarchy.
# Note that this does not affect the filesystem searching or caching,
# which always collect all results on the premise that anyone using
# completion of Perl modules will use the results in various contexts,
# so this only affects the results compadd'd.
#
# --strip-prefix: when using --perl-hierarchy, strip off that prefix when
# passing to compadd.
#
# All other options passed onto compadd.
#
# Available styles:
#
# * try-to-use-pminst
#
# Set this if you have pminst and want to use it. The zsh code
# actually produces better results because pminst misses modules of
# the form Foo/bar/Baz.pm through its clumsy -d && /^[A-Z]/ && prune
# algorithm (the zsh code does almost the same, but only misses
# modules which don't begin with an uppercase letter).
_perl_modules () {
# Set a sensible default caching policy. This has to be done inside
# this function otherwise we wouldn't know the context for the style.
