text-bibtex's Introduction

  Text::BibTeX
---------------------------------------------------------------------------

  Text::BibTeX is a Perl library for reading, parsing, and processing
  BibTeX files.  It is the Perl half of btOOL, a pair of libraries for
  dealing with BibTeX data.

  Text::BibTeX gives you access to the data at many different levels:
  you may work with BibTeX entries as simple "field -> string"
  mappings, or get at the original form of the data as a list of
  simple values (strings, macros, or numbers) pasted together.  You
  can choose not to impose nany restrictions on the allowed/expected
  entry types or fields, or you can use the structure defined by
  BibTeX 0.99's standard style files, or you can invent your own.

  The library is copiously documented.  After installing the module,
  see the Text::BibTeX man page for a comprehensive introduction to
  the system.  If you wish to dive straight in without regards for
  niceties such as splitting and formatting names, defining or
  imposing database structures, getting access to unprocessed field
  values, and other nifty features, then you can probably get away
  with just reading the Text::BibTeX::Entry man page.
  Comments/criticism of the documentation are welcome.


  In addition to the man pages embedded in each module (and available
  after installation), Greg Ward has written a technical report
  describing btOOL, with the btparse and Text::BibTeX documentation
  included as appendices.  The whole report is just over 100 pages,
  around 45 of which make up the Text::BibTeX documentation (the
  btparse documentation is a further 30 pages).  You can find it at
  the btOOL home page:

    http://www.gerg.ca/software/btOOL/


  INSTALLATION
---------------------------------------------------------------------------

  To install Text::BibTeX you need a recent Perl, an ANSI-compliant C
  compiler and a bunch of Perl modules.

  The build system changed with version 0.40, and has been tested in
  different platforms, ranging from Linux, Mac OS X, Solaris and
  Windows. Unfortunately on this last just the Strawberry Perl
  distribution was a success.

  To build the module use the usual set of commands for a
  Module::Build distribution:

    perl Build.PL
    ./Build
    ./Build test

  And then, as super user, install it

    ./Build install

  Note that if your Perl is installed in a non standard path you can
  end up with libbtparse library in the wrong place. If the tests pass
  successfully, but after installing you can not issue

    perl -MText::BibTeX

  without an error message, then probably libbtparse is not reachable
  by the library loader. In this case you can either copy the library
  to the proper place or add the path to the library in the
  LD_LIBARY_PATH environment variable.

text-bibtex's Issues

Is there any way to make the parentheses and space be contained in bibtex entrykey？

hello

I am a biblatex/biber user, and encountered an error while biber was parsing the bib file, which contained entries with entriekey containing () or ' ', the biber/biblatex author told me that it was caused by btparse(biber use btparse), so I am here to ask about some improvement or measure to overcome this problem.

for an entry:

@misc{Euclidean_geometry(hi),
howpublished = {https://zh.wikipedia.org/wiki/abc},
title = {Euclidean geometry},
}

the biber output is:

INFO - This is Biber 2.12
INFO - Logfile is 'egtest.blg'
INFO - Reading 'egtest.bcf'

and for an entry:

@misc{how are you,
howpublished = {{www.baidu.com}},
title = {how are you},
}

the biber output is:

INFO - Logfile is 'egtest4.blg'

Warning during self-tests

When running the self tests for 0.80 with perl-5.24.1, they all succeed but there are warnings in the middle:

Try to reduce memory mount from C code

some strings after getting from C, are not being freed by the garbage collector.
Not a big issue, as we deal with small strings, and even with some thousand bibtex entris, memory only raises to 80MB or so... but keeping this ticket just to remind of the problem

all lowercase names

When a name is all lowercase and has a comma, such as
author="shelat, abhi"
it is parsed as:
<first>abhi</first><von>shelat abhi</von><last></last>
Note that one of the words is duplicated

With no comma, it seems fine.
author="abhi shelat"
is parsed as:
<first></first><von>abhi</von><last>shelat</last>
which is the same thing that BibTeX does.

Problem with double last name parsing

There appears to be a problem with parsing double last names, which in some cases produces an "internal error: bad token join method" error. I've pushed a branch reproducing the problem here:

https://github.com/kwwette/Text-BibTeX/tree/nameformat-bug

Note that since the error comes from accessing out-of-bounds memory, the test doesn't fail every time, but if you run "./Build test" a few times it should fail.

For completeness the patch is also here:

https://gist.github.com/kwwette/d07dee95faa8cc0522fb3d4b3cb82bbc

ld 2.3.0 doesn't recognize -Wl,-soname

I'm building Text::BibTeX manually with an almost-static build of Perl in order to eventually port biber to WebAssembly. Getting build errors from Text::BibTeX. Could you advise how to hack around the build script?

Reading from strings or string-based file handles

I expected one of this to work:

open my $fh, '<', \$somestringwithbibtexdata;
Text::BibTeX::bibloop( sub { }, [$fh] );

Text::BibTeX::bibloop( sub { }, [\$somestringwithbibtexdata] );

Perl supports file handles based on string data since long ago.

Release

Hi, following ef299ab it would be great to have a new release so that the fixed header files get distributed.
Thank you!

month field should support month abbrevs

Accordingly with an RT ticket, we should parse correctly lines like:

    month = aug,

without any quotes. So, for the 12 months.

@plk, do you have some time to dig how to support this in the generated parser?

Buildsystem: export C-header files

If I get it right, atm only libbtparse.so is installed and not the header files. This effect of this is, that the binaries included in Text-BibTeX will work, but other programs that use btparse directly cannot be compiled against Text-BibTeX. Nevertheless due to the fact, that libbtparse.so is installed, it prevents the systemwide installation of old ptparse.

It would be nice, if you include an (maybe optional) export of btparse.h and the creation of a pkg-config file (the old btparse seems to create libbtparse.a and libbtparse.la as well, I get this from this list).

In fact distributions like Debian seems to patch this in the appropriate way already.

Cannot install version >= 0.86 using cpanm

When I try to install Text:BibTeX using cpanm, I get the error (full verbosity enabled) as presented below. Could you please investigate?

[question] how to support aliases for entry types

Hello,

I need to parse a BibTeX file which, in addition to the standard types, also contains some custom entry types, such as 'slides', 'lecturenotes' etc. which all have exactly the same constraints as the entry type 'misc'. Could you please give me some pointers on how to achieve this?

I already skimmed the documentation about setting up a custom structure but have a feeling that it can be done in a couple of lines by inheriting from Text::BibTeX::BibEntry (all the custom types are basically just aliases for 'misc').

Thanks a lot in advance!

Some tests failing on Solaris

I have been receiving some reports of tests for Solaris.

If anyone has access to one and can check what might be going on, I would be grateful.

Test failures with 0.75_01 (trivial fix)

Nearly all the tests fail for me. This appears to be caused by a single line that also yields this warning for me:

Warning: Use of "defined" without parentheses is ambiguous at <path>/blib/lib/Text/BibTeX/Entry.pm line 509.

The line is

@x = map {defined ? Text::BibTeX->_process_result($_, $self->{binmode}): undef} @x;

If I change it to

@x = map {defined($_) ? Text::BibTeX->_process_result($_, $self->{binmode}): undef} @x;

the warning goes away and all tests pass:

For comparison, this is what I get if I leave the line as-is:

Add option to silent warnings

Some warnings from the C library are relevant. Some others, might not.
the warning: overriding existing definition of macro x might be useful on situations, but some others, is just annoying.

An option to be more or less verbose would be nice.

Build starting failing "s390" architecture

Hi, in Fedora GNU/Linux, we've started seeing test failures, I think after moving to Perl 5.24. Unfortunately they only seem to happen on "s390" architecture which I don't have access to---I'm not even sure what it is ;-)

Do the following failures mean anything to you? Basically, instead of getting "J." we get ", J.".

Build failure: insufficient Config::AutoConf version

Text-BibTeX 0.88 on OS X 10.13 with Apple's perl-5.8.12 fails during Build.PL:

Can't locate object method "check_func" via package "Config::AutoConf" at inc/MyBuilder.pm line 86.

even though I have Config::AutoConf-0.19 installed (Build.PL and META.yml say 0.16 is the minimum). Turns out check_func was not added until 0.306.001. (ambs/Config-AutoConf@0.305...0.306_001)
