[PATCH] org.el: Don't flyspell check within source code blocks

[Trevor Murphy]

Hi, list.

I recently started using flyspell, but I wasn't pleased with the spell
checking in my source code blocks.  After digging a bit for a
solution, I found a post to the list with a nice solution[0].
However, it seems no patch was ever submitted.  So, here goes.

If there's a deeper reason this part of the code was never changed,
please enlighten me.  I didn't see any further mailing list
discussion, so I assumed it was still fair game.

Thanks,

Trevor

Ack, what?  Please disregard, I slipped a double negative in somehow.

I think `org-in-src-block-p', while a bit less reliable, will be
faster, and reliable/fast enough for this use-case.

Let's see what others think/test.

Thanks,

Thanks, Bastien.  Your suggestion has been working perfectly fine for me.
 Updated patch sent in reply to the first in the chain (I hope ... still
trying to master git send-email).

For the record, here are the results of a very unscientific profiling of
the patch above. On my woefully under-powered and aging Atom processor,
For each scenario I typed without errors "The quick brown fox jumps over
the lazy dog."

With the old behavior (i.e., no test for source blocks):

org-mode-flyspell-verify  27          0.005580378   0.0002066806

With the patch above:

org-mode-flyspell-verify  27          0.35359755    0.0130962055

Using (not (org-in-src-block-p)), as Bastien suggests:

org-mode-flyspell-verify  27          0.0112581490  0.0004169684

With org-in-src-block-p, a half of a hundredth of a second spread over
27 characters causes no noticeable slowdowns.

But using org-element-at-point causes the cursor to lag a bit.

So +1 is for (not (org-in-src-block-p)).

Best,
Matt

Hi Trevor,

I would be worried that this has noticeable impact in Emacs performance during normal typing.  Are you a fst typist?  Have you noticed anything in this direction?

Thanks!
