bitstring is a Python module that helps to make the creation and analysis of binary data as simple and natural as possible. Objects can be constructed from integers (big and little endian), floats, hex, octal, binary, byte data, iterables, or files. They can be sliced, joined, reversed, packed, unpacked, inserted into, overwritten, and otherwise operated upon with simple functions or slice notation. They can also be parsed, searched, and navigated in, similar to a file or stream. Internally the data is efficiently stored as byte arrays. It is available for Python 2.6 and later (including Python 3).
GraphicsMagick is a robust collection of tools and libraries which support reading, writing, and manipulating an image in over 90 major formats including popular formats like DPX, DICOM, BMP, GIF, JPEG, JPEG-2000, PDF, PNG, PNM, SVG, and TIFF. A high-quality 2D renderer is included, which provides a subset of SVG capabilities. C, C++, Perl, Tcl, and Ruby are supported. Originally based on ImageMagick, GraphicsMagick focuses on performance, minimizing bugs, and providing stable APIs and ABIs. It runs on all modern variants of Unix, Windows, and Mac OS X.
LuaRocks is a deployment and management system for modules in the Lua programming language. It aims to provide facilities for Lua such as those from module systems of other scripting languages, such as Ruby's RubyGems or Perl's CPAN. LuaRocks allows Lua modules to be installed as self-contained packages called "rocks", which also contain version and dependency information.
curl and libcurl is a tool for transferring files using URL syntax. It supports HTTP, HTTPS, FTP, FTPS, SCP, SFTP, TFTP, DICT, TELNET, LDAP, POP3, IMAP, SMTP, RTSP, RTMP, and FILE, as well as HTTP-post, HTTP-put, cookies, FTP upload, resumed transfers, passwords, port numbers, SSL certificates, Kerberos, and proxies. It is powered by libcurl, the client-side URL transfer library. There are bindings to libcurl for about 40 languages and environments.
The Tecla library provides programs with interactive command line editing facilities, similar to those of the Unix tcsh shell. It supports recall and editing of previously entered command lines, TAB completion of file names and application specific tokens, and in-line wild-card expansion of filenames. The optionally reentrant modules which perform TAB completion and wild-card expansion are also available separately for general use. The library is smaller, more modular, makes more efficient use of the heap, and has a less restrictive license than GNU readline.
Gecode is a portable, accessible, and efficient environment for developing constraint-based systems and applications. Gecode is radically open for programming, meaning that it can be easily interfaced to other systems. It supports the programming of new propagators (as implementation of constraints), branching strategies, and search engines. New variable domains can be programmed at the same level of efficiency as finite domain and integer set variables that come predefined with Gecode.
