Hi list,
Once again, I did some basic learning on my own, and was able to come up
with a passable solution, TIMTOWTDI. Probably far from idiomatic, but it
gets the job done in my basic testing.
I looked at the flymake code, finding the flymake-report-status function
called with the error and warnings count string, formatted like "%d/%d".
Looking at the calls to that function, the only one having a non-empty error
string is the one that posts the updated error and warnings counts on the
mode line. In case of no errors or no warnings, it does not post 0/0.
Here's what I added in my .emacs file:
(defadvice
flymake-report-status
(before beep-on-flymake-failure (e-w &optional status) activate)
"Play not_ok.wav in ~/emacs if we have a non-empty error count string."
(if (and e-w (> (length e-w) 0 ) )
(play-sound-file "~/emacs/not_ok.wav")
) ; if
) ; advice
The ending comments make it easier to mentally track the parens, with a
screen reader.
I have also realized that playing another wav in the else case is a bad idea
as every succesful syntax check would beep reassuringly. That's far too
often to be gratifying, <smile>. Plus the sounds play synchronously, on
Win32 at least, ouch, so I'm keeping things brief. As in my OS sound scheme,
the error is a 40 ms quiet burst of pinkish noise.
On a side note, Is there an easy way to only get the syntax chekc after a
time out, on leaving the current line? OFten I leave the cursor on what I'm
editing and start thinking, yet my statement may well be in a syntactically
incorrect state at that point. I don't always hit C-j at the ends of lines,
either, if I'm editing an existing statement in stead.
Hope this helps somebody else some day, too.
