Case sensitivity of searches in virtual buffers are not preserved with find next

[dkager]

STR:

1. Find a webpage that contains some text both with and without capitals, e.g. The and the.
2. Press NVDA+Ctrl+F, type the text with capitals.
3. NVDA finds the text. Now rpess NVDA+F3.
4. Eventually NVDA will find an occurrence without capitals.

And a patch in dkager/nvda@d64fb8b. Feel free to not use it and do something far more sophisticated!

Hi,

If I remember right, we had a discussion about this while I was implementing case sensitive find (#4584) last year. I’d say let’s leave it as is unless there is a strong reason to preserve case sensitivity (of course we could have a flag indicating that it is a case sensitive find in cursor manager).

Thanks.

My ‘strong reason’ is that if I perform a case sensitive search, then ask for the next result, I expect that next search to also be case sensitive. This is especially true in the log viewer (#4929, which I also worked on today). But also when searching through developer documentation in browse mode, if you are looking for SOMETHING you probably don’t want to find SomeThing with the next search (note the caps). Similarly, it struck me as odd that the last search text is preserved but the state of the case sensitive checkbox isn’t.

[dkager]

Having given this some more thought I still think this suggestion makes sense: consecutive searches for a phrase should use the same parameters that were used in the initial search for that phrase. Whether a new search should also remember the parameters is a topic of discussion. I think this is useful but I can imagine others may find it confusing. And of course these parameters should not be persistent, i.e. they revert to their defaults when you restart NVDA.

Any renewed thoughts on this Joseph? :) I'm not trolling (well, not intentionally). I just ran into real-world cases where I'd like my search parameters to be preserved as described above. For example, when searching in JavaDoc files.

[jcsteh]

I don't recall the previous discussion on this, but IMO, if someone is willing to code it, we should preserve this setting (but not across restarts of course). Aside from anything else, this is consistent with other programs that have find functionality. I can't think of any find dialog which doesn't keep the settings across executions.

[derekriemer]

In reguards of implantation:
I have refactored def onOk(self, evt):
text = self.findTextField.GetValue()
caseSensitive = self.caseSensitiveCheckBox.GetValue()

     wx.CallLater(100, self.activeCursorManager.doFindText, text, 

caseSensitive=caseSensitive)

to
def onOk(self, evt):
text = self.findTextField.GetValue()
caseSensitive = self.caseSensitiveCheckBox.GetValue()
self.caseSensitive = caseSensitive
wx.CallLater(100, self.activeCursorManager.doFindText, text)

and might be able to remove the whole arguement for caseSensitive from
doFindText and then have doFindText lookup the option from
self.caseSensitive. Is this a rework you guys are okay with?

If you do self.caseSensitive, you're storing it on the instance of the dialog. That instance gets thrown away as soon as it's done, so it won't get preserved across finds. Instead, you need to store it as a class attribute (not an instance attribute) on CursorManager. That also allows you to get rid of the caseSensitive argument to doFindText.

[derekriemer]

Done. I will commit tomorrow. Btw, unless anyone objects (doubt it) I am
gonna update the copyright date of source/cursorManager.py to 2016 with
the pr.

Also, the checkbox should get the right selection state based on this attribute of course. See my commit linked to in a comment above, which was rather dirty but shows what I had in mind.

Oh. We do indeed preserve the text's state as part of the find dialog. I
probably should preserve the case sensitivity as well.

I think you reviewed the PR for this a while ago and it stalled. We had
to update a copyright date and after that it was not re reviewed.

Hi,

Uh oh, we need to nudge devs a bit then… If there’s virtually no change between the code I reviewed and the new commit, then I’d say we should wait for a little while until @jcsteh can take a look at this further. Thanks.

jcsteh commented on Jan 7:

this is consistent with other programs that have find functionality.

1. Speaking of consistency, should we change the check-box's label to "Match case", like in almost all Find dialogs?
2. Also, should the accelerator key be Alt+C rather than Alt+S (e.g. Notepad, Wordpad, and Firefox)?
3. Oh, and for future reference, should I be opening a new ticket even though the issue somewhat relates, i.e., expected or standard behavior?
