csvgroupby is a small utility program that allows you to obtain aggregated statistical information from comma-separated files containing tabular data. It is similar to the SQL GROUP BY clause. It currently supports the COUNT, MAX, MIN, SUM, and AVG operators. It performs as many processing jobs as possible in a single run through the data file, which means that large data sets can be efficiently processed.
TXR is a new data munging language to replace the likes of awk and Perl. TXR's special pattern language provides template-based matching of entire documents or large sections of documents. It also contains a language for functional and imperative programming. It is written in C and takes the form of a utility that is portable to Unix-like platforms and Windows.
Minimac is a minimalist, general purpose text macro processor. Its simplicity should make it particularly well suited as a front end preprocessor for little language compilers. It is meant to be simpler to use than m4. It uses an explicit argument stack, and user functions are defined by concatenation (similar to the Forth language). Macro expansion is delayed to the last possible moment. The software is currently in alpha release.
Dwoo is a template engine for PHP5 where you write less and do more. It is mostly compatible with Smarty templates, but it's a full rewrite that builds upon Smarty's syntax to offer more flexibility, both in templates and in PHP extensibility. It also comes with a few adapters for the major PHP development frameworks.
