CL-PDF is a cross-platform Common Lisp library for generating PDF files. It does not depend on any third-party tools from Adobe or others. CL-Typesetting is a complete typesetting system written in Common Lisp using CL-PDF. Both projects were originated and are being maintained by Marc Battyani.

The corresponding home pages are

The original repositories are here:

• https://github.com/mbattyani/cl-pdf
• https://github.com/mbattyani/cl-typesetting

Ystok-PDF was forked in 2009. Now it has the following properties:

• Does not depend on the iterate package.
• Relies on Salza2 developed by Zachary Beane.
• Was not tested with TrueType fonts.
  For dealing with them, one could use the following utility: ttf2pt1 (the Windows binary is available here). It generates the AFM file and, if needed, the PFB file.

Download and installation

Ystok-PDF is available from
http://lisp.ystok.ru/cl-pdf/ypdf-2-0-006.zip.
The distribution package contains both the ASDlite/ASDF-based ystok-pdf.asd and the LispWorks system definition file defsys.lisp.

CL-Typesetting example with Cyrillic

I must admit I have failed referring to a TrueType font without embedding it. Here is ex-1251.zip containing all the files needed for reproducing the ex-1251.pdf (184 KB) on LispWorks for Windows. The document demonstrates a justified paragraph written down with the Arial Cyrillic Type1 font.

Contribution to the CL-PDF distribution

The main reason for forking Ystok-PDFy was poor maintenance of the "official" distribution and some disagreements. The brief list of my code additions and improvements made before 2009 is as follows.

• Support of the national languages not based on the Latin-1 character set:
  • the force-char-code macro,
  • two write-object methods (assuming restricted use of national characters only in content streams only),
  • one write-document method and the with-page macro.
• PNG images support.
• CL-Typesetting example with multi-page content and tables
• LispWorks optimizations for Salza (not Salza2) based on INT32 API introduced in LW 4.4.
