13 Odds and Ends
****************
The stuff that didn’t fit in anywhere else is documented here.
-- User Option: c-require-final-newline
Controls whether a final newline is enforced when the file is
saved. The value is an association list that for each language
mode specifies the value to give to ‘require-final-newline’ (
(elisp)Saving Buffers) at mode initialization. If a language
isn’t present on the association list, CC Mode won’t touch
‘require-final-newline’ in buffers for that language.
The default is to set ‘require-final-newline’ to ‘t’ in the
languages that mandate that source files should end with newlines.
These are C, C++ and Objective-C.
-- User Option: c-echo-syntactic-information-p
If non-‘nil’, the syntactic analysis for the current line is shown
in the echo area when it’s indented (unless
‘c-syntactic-indentation’ is ‘nil’). That’s useful when finding
out which syntactic symbols to modify to get the indentation you
want.
-- User Option: c-report-syntactic-errors
If non-‘nil’, certain syntactic errors are reported with a ding and
a message, for example when an ‘else’ is indented for which there
is no corresponding ‘if’.
Note however that CC Mode doesn’t make any special effort to check
for syntactic errors; that’s the job of the compiler. The reason
it can report cases like the one above is that it can’t find the
correct anchoring position to indent the line in that case.
