Bug #43014 for BibTeX-Parser: Author names with non-word characters

Tue Feb 03 22:08:39 2009 chong [...] seas.harvard.edu - Ticket created

Subject:	Author names with non-word characters
Date:	Tue, 03 Feb 2009 19:07:57 -0800
To:	bug-BibTeX-Parser [...] rt.cpan.org
From:	Stephen Chong <chong [...] seas.harvard.edu>

Hi, I think there is a bug in the pattern used to match author names, on line 141 of Author.pm. The expression \b([\w-]+) does not match surnames that contain, for example, an apostrophe, such as "O'Malley". Thanks for writing/maintaining this, it is very useful! Cheers, Steve.

Hi Gerhard, hi Steve, I'm also suffering from a related problem (but probably not exactly the same as Steve). The following BibTeX entry sends the parser into an endless loop: @article{testkey, year = {2008}, author = {A. Bar and L.M. M\"uller}, journal = {journal}, volume = {1}, number = {1}, pages = {1}, } I'd really, really appreciate to get this issue fixed! I'd hate having to write my own parser :( Thanks for writing the parser! Cheers, Steffen

please find two files in the attachments: t/bibs/10-funnyname.bib and t/10-funnyname.t which test the related bug. The infinite loop only occurs when the ->author or ->editor methods are called. Best regards, Steffen

Oddly, the attachment didn't work the first time. Trying again with only one each time. This should be the test file.

#!perl -T use Test::More tests => 11; use IO::File; use BibTeX::Parser; my $fh = IO::File->new('t/bibs/10-funnyname.bib'); my $parser = BibTeX::Parser->new($fh); #my @result = BibTeX::Parser->_parse($fh); my $entry = $parser->next; is_deeply( $entry, { _type => 'ARTICLE', _key => 'testkey', author => "A. Bar and L.M. M\"uller", title => 'foo', journal => 'journal', volume => 1, number => 1, pages => 1, year => 2008, _parse_ok => 1 }, "parse \@ARTICLE" ); my @authors = $entry->author; pass("->author didn't loop forever"); ok(@authors == 2, "Two authors"); is($authors[0]->first, 'A.', "A1 first name"); is($authors[0]->last, 'Bar', "A1 last name"); ok(!$authors[0]->von, "A1 no 'von'"); ok(!$authors[0]->jr, "A1 no 'jr'"); is($authors[1]->first, 'L.M.', "A2 first name"); is($authors[1]->last, 'M"uller', "A2 last name"); ok(!$authors[1]->von, "A2 no 'von'"); ok(!$authors[1]->jr, "A2 no 'jr'");

This should be the test BIB file.

@article{testkey, year = {2008}, title = "foo", author = {A. Bar and L.M. M\"uller}, journal = {journal}, volume = {1}, number = {1}, pages = {1}, }

Hi, I fixed both problems in version 0.3 which should be on CPAN now. If you find any additional names that cause problems I would be glad to hear about them.
