white_dune is a graphical VRML97/X3DV editor, simple NURBS/Superformula 3D modeller, animation tool, and VRML97/X3DV commandline compiler in development. VRML97 (Virtual Reality Modeling Language) is the ISO standard for displaying 3D data over the Web via browser plugins ("HTML for realtime 3D"). X3DV is the direct successor of VRML97. VRML97 and X3DV have support for animation, real-time interaction, and multimedia (images, movies, and sounds). white_dune can read, create, and display VRML97/X3DV files and let the user change the scenegraph/fields. It also has support for stereoscopic view via "quadbuffer"-capable stereo visuals, and support for 3D input devices like a joystick, spaceball, or magnetic tracker.
cygbuild is a porting tool for making Cygwin net releases. It helps Cygwin source and binary package maintainers to configure, build, strip, produce diffs, and generate Cygwin specific files. To put it simply, it converts any freely available program or package into a complete Cygwin net release distribution.
bmake is a program designed to simplify the maintenance of other programs. Its input is a list of specifications as to the files upon which programs and other files depend. If no -f makefile makefile option is given, bmake will try to open 'makefile' and then 'Makefile' in order to find the specifications.
OMake is a build system and scripting language with a similar style and syntax to GNU make but with many additional features, including support for large projects spanning multiple directories, default configuration files simplifying the standard compilation tasks, fast, reliable, automated, scriptable dependency analysis using MD5 digests, built-in support for defining and running autoconfiguration tests, portability, and built-in functions that provide the most common features of programs like grep, sed, and awk. It also provides active filesystem monitoring that restarts builds automatically when source files are modified. A companion command interpreter that can be used interactively is included.
KJam is a very fast build tool. It is a make replacement, and uses a syntax similar to Jam, but is much more powerful than the original. It has built-in dependency scanning, per-target viewpathing, C-like control flow, and a built-in sh-like shell. It is optimized for multi-processor machines. It can accelerate software builds by launching build actions on a distributed peer to peer network of build servers. It is designed to support large projects with thousands of targets, or projects requiring building on many target architectures.
The d command runs a command in the background and redirects its output to a file. The output file is annotated with start and end time, the actual command used, cwd, host, etc. You can ask the d command to extract the last command from the output file and run it again, you can ask it to append to the file or not, and other goodies. It comes with handy little programs to look at the output, tail it, etc. It is sort of trivial, but has been streamlined over many years.
GODI provides an advanced programming environment for the Objective Caml (O'Caml) language. From INRIA (who created O'Caml) you can get the O'Caml compiler and runtime system, but this is usually not enough to develop applications. You also need libraries, and there are many developers providing them. But it is a lot of work to build and install them. GODI is a system that simplifies this task: It is a framework that automatically builds the O'Caml core system, and additionally installs a growing number of pre-packaged libraries. For a number of reasons, GODI is a source-code based system, and there are no precompiled libraries, but it makes it very simple for everybody to compile them.
Gnasher alleviates developers from having to execute maven builds with the "-o" option (offline) to avoid accessing external repositories' metadata files. The SHA1 hash files and the missing pom metadata files for dependencies are created if they are missing. The next time the build is run, external repositories are not accessed and the build runs faster.
Oink is a collaboration of backends for the Elsa C and C++ frontend. It aims to be industrial-strength for immediate utility in finding bugs, extensible for ease in adding backends, and composable for ease in combining existing ones. It computes expression-level and type-level data flow, and statement-level intra-procedural control flow (by delegating to Elsa). It's easy to get started by using the two demo backends that print graphs of these flows. It also comes with a client of the data flow analysis that does type qualifier inference: Cqual++, a C/C++ frontend for Cqual. Whole-program analyses may be attempted using the linker imitator.
