I'm looking for a way to programmatically retrieve documentation for mode-line-format %-constructs; this is part of a little project I'm working on to help with mode-line customization. So for example, if the mode line contains "%e", I want something ike:

(display-mode-line-format-percent-help "%e")

to return:

print error message about full memory.

Right now the only way I can think of is to parse the help string for mode-line-format, but that seems like it would put me in a state of sin. :-) Is there a better way?


I'm afraid you'll have to sin. The information you are after is only in mode-line-format, so that's what you have to inspect.
