Maybe the DM42?
programmable? kinda
rugged? a steel or titanium case, not sure, but yes
keyboard? should be good based on prior form
clock? yes
alarm? don't think so
e-ink? yes
weeks of battery? yes
This device may be hackable in the future, but it will be released based on free42 and Intel's quad-precision decimal library which I think will make it the most accurate handheld calculator.
Another option might be the numworks calculator[2] which runs python and is open source. But doesn't meet your other criteria.
A third option might be the Gemini - a folding clamshell that runs linux.[3] or even the pocket chip? [4]

- JohnStrange 9y agoPocketChip: only 5 h battery life, not durable, but otherwise would be ideal - but with 5h battery life it's nothing but a useless gimmick DM42: no alarm, too limited programming (basically a HP42 clone), no CAS, otherwise it would be ideal gemini pda: too short battery life, way too expensive numworks: kind of cool, but doesn't meet the criteria either, and it currently still has math problems (accuracy changes with every firmware update, the least thing I want from a calculator is inconsistent floating point arithmetic) If I knew more about electronics, I'd make my own device but my life is unfortunately too short and too busy for that. I guess you can't always get what you want. ;)
