BibTeX Parser

Simple, singler-header (bibtex.h) BibTeX file parser. The header file includes documentation and usage examples.

Limitations

For simplicity this library avoids string allocation and copying whenever possible, as a result of this it has the following limitations (most of which can be handled by clients of this library):

• Does not trim spaces or newlines on string entries.
• Does not process brackets embedded in string entries.

Usage

#include <stdio.h>

#define BIBTEX_INCLUDE_IMPLEMENTATION
#include "bibtex.h"

int
main(int argc, char** argv)
{
  Bibtex_Entry *entry;
  Bibtex_Reader reader;
  Bibtex_Result *result;

  result = bibtex_reader_load_file(&reader, argv[1]);
  if (result->error)
  {
    fprintf(stderr, "error: %s\n", result->message);
    return(1);
  }

  while (bibtex_reader_is_valid(&reader))
  {
    result = bibtex_reader_next(&reader, &entry);
    if (result->error)
    {
      fprintf(stderr, "error: %s\n", result->message);
      return(1);
    }

    if (entry != NULL)
    {
      /* do something with the next bibtex entry */
    }
  }

  bibtex_reader_destroy(&reader);

  return(0);
}
