I don't think the log helps.
The log files contain absolute paths, so they would need lots of replacements before you can even start comparing. They contain version information for the packages - but checking whether a new version gives identical results is one of our goals. And renamed files, or splitting a package into different input files loaded by the "master" file, would completely break when we would try to automatically parse the log file.
i had the impression that you wanted to test if teh pdf files were ok and then you don;t need to compare with older files; just analyze the log for anomalities (like missing resources which point to a problem in the font setup - which is the most probable source of problems); regression tests at the macro package (output) level is something else; afaik latex already has regression tests; as said: analyzing the page stream or objects is non trivial, and even simple changes in pdftex or in annot/object/literal support will make a comparison nearly impossible Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
