Delain has been developed for quite some time now. See the ChangeLog for details or try out the older versions.


Delain is open source software, licensed under the AGPL3+.

Install Delain


Installing and running Delain requires a bunch of other tools:

Running requires:
Compiling requires:
  • GCC - The GCC compiler
Testing requires:
  • Valgrind - Valgrind is an instrumentation framework for building dynamic analysis tools. There are Valgrind tools that can automatically detect many memory management and threading bugs, and profile your programs in detail.
  • LCOV - LCOV is a graphical front-end for GCC's coverage testing tool gcov. It collects gcov data for multiple source files and creates HTML pages containing the source code annotated with coverage information.
  • Autotools test suite - Part of the GNU Auto-Tools for automated Tests
Contributing requires:
  • flex: The Fast Lexical Analyzer - Flex is a tool for generating scanners. A scanner, sometimes called a tokenizer, is a program which recognizes lexical patterns in text. The flex program reads user-specified input files, or its standard input if no file names are given, for a description of a scanner to generate.
  • Bison - Gnu parser generator - Bison is a general-purpose parser generator that converts an annotated context-free grammar into a deterministic LR or generalized LR (GLR) parser employing LALR(1) parser tables.
  • GNU Gengetopt - Gengetopt generates a C function that uses getopt_long function to parse the command line options, to validate them and fills a struct .
