I've started sketching out an independent fork/continuation of libmaple and supporting tools, which i'm calling "rambutan". The premise is to drop all-in-one IDE support and focus on the core C library for peripheral and family completeness within the STM32 M3/M4 line. Being hardware-neutral and making development on custom boards easy is also a priority.
This isn't an official leaflabs project. I'm also now not a leaflabs employee, just a friend and fellow traveler. But it does have their blessing and may get some patches and support from individual developers in the future.
The current plan is to do a "v0.1" of librambutan that would largely backwards compatible with libmaple (master branch), including the build system, to make it easier to accept outstanding libmaple ports and patches. "v1.0" development could include refactoring of symbols and filenames, breaking compatibility.
The project website (http://rambutan.cc) links to forums, code, and documentation. There are probably some rough edges. I will be in transit (moving to Seattle! Wo!) for the next two weeks, but will try to keep up with discussion. Tooling, policy, and documentation will probably take priority over development or merging code until early October.
Comments, advice, cynicism, and patches are all welcomed! If this was to become the collective continuation of the leaflabs forum community as well i'd be really happy, though that may be presumptuous to propose.
