libplis is library for Perl-like string manipulation for C++. It includes the string class plis::slip and the list class plis::llip. Together, these two provide the Perl-like methods that include regular expressions (through PCRE), split(), join(), grep(), chomp, tr///, s///, sprintf(), etc. It can also be described as a C++ frontend to PCRE, but its array manipulations make it much more powerful than only that. It comes with Doxygen API documentation.
paps is a text to PostScript converter that works through Pango. Its input is a UTF-8 encoded text file and it outputs vectorized PostScript that is quite compressed. It may be used for printing any complex script supported by Pango. paps supports landscape and portrait printing as well as multiple columns. paps includes libpaps, a library that facilitates creating PostScript output from UTF-8 encoded strings from other programs.
libxnm is a library for parsing and retrieving data from the XNM file format. XNM stands for "Xnm is Not a Markup language" in the spirit of GNU recursive definitions. XNM is a simple recursively defined serialization syntax that is well suited to be used as a storage format for any program storing or communicating complex datastructures. In contrast to the XML standard, XNM was built to be as concise as possible. It is built around four types: the recursive tables and arrays, and the end nodes strings and binary chunks.
GemTcl (Gtk Embedded Tcl) is a cross platform Tcl shell written in Gtk. In addition to interactive use, it supports the creation of buttons that may contain user-defined Tcl scripts. GemTcl also supports the loading of Glade interfaces for which the callbacks of their buttons may be edited. It may thus be considered as a rapid application development environment. It is especially suited for control applications, and comes with an XML-RPC controlled microscope simulator application to exemplify that.
