auctex: Ignoring warnings
4.3.1 Controlling warnings to be reported
-----------------------------------------
Normally AUCTeX will only report real errors, but you may as well ask it
to report 'bad boxes' and warnings as well.
-- Command: TeX-toggle-debug-bad-boxes
('C-c C-t C-b') Toggle whether AUCTeX should stop at bad boxes
(i.e. overfull and underfull boxes) as well as normal errors. The
boolean option 'TeX-debug-bad-boxes' is set accordingly.
-- Command: TeX-toggle-debug-warnings
('C-c C-t C-w') Toggle whether AUCTeX should stop at warnings as
well as normal errors. The boolean option 'TeX-debug-warnings' is
set accordingly.
While many users desire to have warnings reported after compilation,
there are certain warnings that are considered unimportant and users
want to ignore them. For a more fine-grained control of what kinds of
warnings should be shown after compilation, AUCTeX provides other
options.
-- User Option: TeX-ignore-warnings
Controls which warnings are to be ignored.
It can be a regexp matching the message of the warnings to be
ignored.
More advanced users can set also this option to a symbol with the
name of a custom function taking as arguments all the information
of the warning listed in 'TeX-error-list' variable, except the last
one about whether to ignore the warning. See the code of
'TeX-warning' function and the documentation of 'TeX-error-list'
for more details.
-- Command: TeX-toggle-suppress-ignored-warnings
('C-c C-t C-x') Toggle whether AUCTeX should actually hide the
ignored warnings specified with 'TeX-ignore-warnings'. The boolean
option 'TeX-suppress-ignored-warnings' is set accordingly. If this
is nil, all warnings are shown, even those matched by
'TeX-ignore-warnings', otherwise these are hidden.
Note that 'TeX-debug-warnings' takes the precedence: if it is nil,
all warnings are hidden in any case.
