! Highlighting Patterns for BibTeX
!
!    http://volker.dnsalias.net/soft/nedit/
!
! Tested with NEdit 5.4.
!
! Load this file by starting nedit with:
!
!     nedit -import <the name of this file>
!
! Then, check that the patterns were loaded correctly, and choose Save Defaults
! from the Preferences menu. The new patterns will now be incorporated into
! your own .nedit file, so the next time you start NEdit, you will no longer
! need to use -import.
!
! This language mode is currently called "BibTeX KW", for keyword, because
! certain BibTeX identifiers are highlighted differently. I might make another
! language mode "BibTeX" where that is not the case. Once loaded, language modes
! can be renamed with
! preferences->default settings->syntax highlighting->recognition patterns
!  ->add/modify language mode, and editing the name.
!
! ChangeLog:
!   Original version: Daniel Blezek, blezek.daniel@mayo.edu
!   10 March 2000, Updated for NEdit 5.1 (MWE)
!   30 Dec 2003: Volker Kuhlmann <VolkerKuhlmann@gmx.de>, NEdit 5.4
!     Substantial improvements:
!	- Highlighting of month names, digits, and macro names
!	- @String definitions now work
!	- BibTeX doesn't distinguish between {..} and ".." as field value
!	  delimiter, therefore there's not much point using different colours
!	  for the value
!	- If the nesting level of braces is exceeded for the field value, things
!	  break very badly for several entries thereafter. Increased levels
!	  which are handled correctly from 2 to 4
!	- The standard entry typed and fields are highlighted in a different
!	  colour
!	- Field names are in a different colour if the previous entry is missing
!	  a trailing comma.
!	  If you have an idea for how to make this bright read instead, please
!	  let me know!
!	- Removed style "BibTeX Field", using "Keyword" instead
!	- Added style "BibTeX newfield", for non-standard entry fields
!	  (currently set to dark brown, style "plain" might be good choice too)
!	- Renamed BracketString to BraceString
!   31 Dec 2003: Volker Kuhlmann <VolkerKuhlmann@gmx.de>
!	- The "scroll entry" macro was missing its last line - ooops!
!	  Thanks to Matthias Odisio <odisio at icp.inpg.fr> for pointing it out.
!	- Added more comments to this file.
!	- @Preamble now highlighted
!	- errornous at-signs in comments are highlighted in bright red
