# New Ticket Created by David Golden # Please include the string: [perl #116975] # in the subject line of all future correspondence about this issue. # <URL: https://rt.perl.org:443/rt3/Ticket/Display.html?id=116975 > The semantics of require are reasonably complex. The perlfunc entry gives an example saying "has semantics similar to the following". Unfortunately, that example leaves out a lot, which could mislead people who -- for whatever reason -- want to try to emulate CORE::require. This patch makes the following changes to bring the "sub require" example closer to the actual behavior of CORE::require. - Loads the filename with the correct calling package - Corrects the phrasing of the error message when a file is not found - Uses croak to show that errors are issued from the caller's perspective - Shows (crudly) how to check if a version number has been passed as an argument instead of a filename Things that are omitted: - The core parses for version numbers in a way that distinguishes numbers from strings: C<< require 6 >> is not the same as C<< require "6" >>. A pure perl require can't do that, so I ignore that distinction and treat anything that looks like a version as a version - There is no localization of %^H, as I'm led to believe this is unnecessary since Perl 5.12 --- pod/perlfunc.pod | 28 ++++++++++++++++++++++------ 1 file changed, 22 insertions(+), 6 deletions(-)Thread Previous | Thread Next
