AutoGen is a tool designed for generating program files that contain repetitive text with varied substitutions. Its goal is to simplify the maintenance of programs that contain large amounts of repetitious text. This is especially valuable if there are several blocks of such text that must be kept synchronized. Output is specified with a Scheme-enhanced output template. Input, if required by your template, may come from AutoGen definitions, CGI data, or XML files.
AutoOpts is an integrated part of AutoGen. Based on a very simple option description file, it will process configuration files, environment variables, command line options, text strings passed by client programs, and will make the results easily accessible to the client program. It will also produce a man page and the info-doc invoking section automatically.
Awka is both a translator of AWK programs to ANSI C, and a separate library against which the C code is linked. The aims of Awka are to allow creation an executable that provides generally better performance than AWK interpretors, to allow easy inclusion of AWK logic in larger C applications, and use of external C functions within AWK scripts.
Ccide reads C, C++, BASIC, or bash source code containing embedded decision tables from stdin, expands the tables, copies the remaining statements, and forms a compilable C or C++ source module, executable bash script, or interpretable BASIC program. Erratic side effects are avoided by evaluating all condition expressions at exactly the same time, and by performing all evaluations and actions in the original sequence.
WriteTarget is a universal text generator based on Bash text substitution. It can be used to generate text in any programming or markup language. The generator does not define its own language; it rather defines several functions, making it possible to use Bash for creating simple or sophisticated templates.
^txt2regex$ is a Regular Expression "wizard", written with bash2 builtins, that converts human sentences to regular expressions. With a simple interface, you just answer questions and build your own regexp for a large variety of programs, such as awk, ed, emacs, grep, Perl, PHP, procmail, Python, sed, and vim (there are more than 20 supported programs). As it is written in bash, no compilation is required.
The goal of XPS is to make programming simpler by raising the level of abstraction without loss of performance. It provides true support for meta-programming and domain specific languages, making it possible to design simple programming languages to match the problem at hand. This is the opposite of current practice which seeks to translate the problem domain down into the low level solution domain of current programming languages.
