Code Crunching

I am looking for a basic (or good) Delphi lexer

Well, I know about DGrok, which seems to be a great tool. However, it is written all in C# and therefore all in .NET only. For a upcoming project, which I want to make open source once finished, I need a lexer, which is written in native Pascal/Delphi. It does not need to be perfect, however, it should return all data of the interface part in units, and it should analyze Delphi-PRAXiSR-Files as well.

The lexer (maybe a simple parser suffices) must be open source and come with just about any license out there, though I prefer MPL over (L)GPL any day.

Anyone with a good hint out there? Thanks!

P.S.: Merry Christmas and a happy new year.

This is the one Castalia was based upon: http://code.google.com/p/castaliadelphiparser/

- Martin WALDENBURG has his mwLexer, which is included in the BDS4 demos under C:\Program Files\Borland\BDS\4.0\Demos\Delphi.Net\VCL\Lexer
- a previous version of this was the basis of EssModel, an UML reverse engineering tool (with source code, of course) which can be found on Torry, I guess
- we have published, here and there, very simplified lexers for dedicated purposes, like finding the USES, converting Pascal or Sql to HTML etc

Those are all scanners (Lexers), not parsers. We have used other lexers / scanners, built from a Pascal / Delphi GRAMMAR. The grammar is published on our site, but we have not published the lexers/scanners at this time.

Hope Santa will bring you this lexer :)

Also, check the FreePascal distro. I think it has an an updated version but I'm not sure.
