[erlang-questions] Controversial subject of the day: tabs and spaces for indentation
Wed Feb 5 20:18:09 CET 2014
It seems to me that this problem is easily solved by inverting the interests:
- Fix erlang-mode to default to all spaces
- OTP team includes the appropriate Emacs code headers in the source
files (or the dot file in the source root directory as Magnus just
pointed out) and leave them horribly formatted, per their preference
Does this not trivially solve the world's Erlang indent problems?
