PicoC is a very small C interpreter for scripting. It was originally written as the script language for a UAV's on-board flight system. It's also very suitable for other robotic, embedded and non-embedded applications. The core C source code is around 4000 lines of code. It's not intended to be a complete implementation of ISO C but it has all the essentials. When compiled it only takes a few k of code space and is also very sparing of data space. This means it can work well in small embedded devices. It's also a fun example of how to create a very small language implementation while still keeping the code readable. picoc has been tested on x86-32, x86-64, powerpc, arm, ultrasparc, HP-PA and blackfin processors and is easy to port to new targets. To show it working on the old DECUS grep program (included as one of its tests): % time picoc work/picoc/tests/46_grep.c - case work/picoc/tests/46_grep.c File work/picoc/tests/46_grep.c: "lower-case are always ignored.
