Version 3.0 of TeXcount will have a number of new features and improvements. The α-version is now available for testing. Most likely, there may be bugs left that I have not detected. I hope to catch most errors before the β-release, so please inform me of any errors or unexpected behaviours.
One of the most obvious improvements is that optional macro parameters, i.e. on the form [...], can now be processed by TeXcount: previously, they were all ignored by default.
There are some other improvements in the handling of macro rules, and as part of this headers no longer need separate sets of rules. Macro rules are no longer specified through cryptic numberical codes, but by keywords; the same applies to counters. It is also possible now to add more counters and so e.g. add rules to count footnotes separately rather than together with captions.
The verbose output can now be customised through the -v= option: the user can specify in great detail which elements are included in the verbose output. For HTML output, the user can also provide an HTML template using -htmlfile=, or CSS style through -css= or -cssfile=.
In Windows, colour coded output should now work, although not perfectly: the background colour tends to get changed. However, it is better than not working at all.
Macro rules for file inclusion commands are now more flexible, and support for the import package has been added. There are also new options -out= to print output directly to file, and -auxdir= to specify directory where auxilary output (i.e. the bbl-files) are stored.
TeXcount can now also collect macro usage statistics though the -macrostat option. This was added in part with the web-service in mind: if the user permits it (logging can be unchecked to disallow), TeXcount will log the number of times macros, environments and packages were used. Through this, I hope to capture packages and macros for which I should add parsing rules.
For improve help, options -help-option and -help-style are provided.
Detail are provided in the documentation. In addition to the TeXcount user manual, and the briefer Quick Reference manual, there is now also a Technical Documentation that explains the Perl code of TeXcount in greater detail.
