mysqltcl is the Tcl interface to mysql realtional database. It is the next version of mysqltcl1.53 (new contributor) with many new futures: Tcl8.0-Object support, Unicode support, configure support, no connection limitation, nested queries, handling of binary files (containing null values), and many extra commands: seek on result block, escaping of string, last inserted id, introspection of connection and query state, and query metadata (schema).
UverseWiki is a modular open source PHP framework designed for text processing. Unlike most existing solutions, it is not regular expression-based but instead uses a recursive descent parser to build a document object model. After the parsing stage has been finished and the DOM is produced, the original source is discarded and all operations are performed on the document tree instead: nodes can be altered, serialized, or rendered into a particular format (such as HTML or RTF). The wiki syntax is language-neutral and the processing itself is carried out in UTF-8.
