Qt Creator Search and Replace
-
Dont get me wrong, I am very fond of Qt Creator. But advanced search and replace is just broken beyond repair hence filing bug reports makes no sense.
Another reason for not filing bug reports for this is that each time I use this dialogue, I have a different issue. Today it is limiting the scope to "selected text" which barely worked before, which is bad enough, but today there is no way to do it (currently on QtCreator 4.11.0).
The documentation for this feature is also broken in the sense that it looks more like a workarround than a howto (the help says something alog the lines: "first select the text and then hope the scope will be limited to that regardless the scope set in the dialog box"). Furthermore I cannot get the help via F1 ( error message: "is blocked, request to server have been blocked by an extension. Try disabling your extension. ERROR_BLOCKED_BY_CLIENT")
By the way, even today, without restarting qtcreator, I had different behaviours. Sometimes the visual representation of the selection changes to some serach-and-replace selection and sometimes not.
I always get the message "this cannot be undone" but this message is only randomly true. If the search scope is limited to a file, I can undo regardless.
And so it goes on and on and on. I have no problems using find and replace in Notepad++, vim or Visual Studio hence I do not believe the problem is with me.
I am just wondering, have people just totally given up on this feature or am I the only one who believes this needs a complete rewrite? Usually I just use sed-command instead but this does not know about selected text of course.

I don't have any issues with search and replace in Qt Creator. "Find usages" (which I often combine with search and replace) has recently got worse. But the replace part works fine.
I know it's not a very constructive feedback :D Just wanted to chime in an mention that it's not bad for everybody.
Btw. "Try disabling your extension" have you tried disabling some extensions? Do you use any non-standard ones?
-
I am using > 30 extensions and I do not know which ones are standard and which ones not.
I do not have find usages. I have find references.
find usages is Visual Studio as far as I remember.But this is interesting. I did not know I can do Find References and then proceed to replace. Do you mean Refactor -> Rename Symbol under cursor? If you mean that, this does not work because I do not have the patched clang version hence some clang plugins do not work.
So, how do you replace in selection? Previously I just selected and then proceeded to Ctrl+Shift+F and it would do its thing. But today it replaces everything inside and outside the selection.

I don't use Qt Creator, so please don't shout if I'm talking rubbish!But I thought Creator, like other IDEs, uses Ctrl+Shift+F for "find in all files", and doesn't do selection only? Isn't it Ctrl+F for "find in (current) file" (or Ctrl+H for "replace in current file") , and that would then work with a selection there?
-
@JonB, you are not correct, and this is a further concern I have with QtCreator's way of doing search and replace. The UI of this feature does everything differently than everyone else. Ctrl+Shift+F opens the "advanced search" and there you can choose the scope (except scope=selection).

@Patrick-Fromberg
OK, I have gone and had a look. Are you perchance falling foul of https://forum.qt.io/topic/33369/solved-search-and-replace-within-selection. Are you aware that it seems you must select at least one "newline" in your selection before replace in selection seems to work?? If I select multiple lines replace works in selection scope, if I have only one line selected (and not its terminating newline) then the Replace All does the whole file. ?When it is going to work in selection only you get to see the selected section outlined with a box, and that's where Replace All does its stuff.
-
@JonB , no this is not my problem but further proof that search&replace is cursed in creator.
-
Unexpectedly nobody has a problem. So one very simple last question.
Shift+Ctrl+F3 works for me but Ctrl+F3 "Find next selected" never did. I work with Linux/KDE. Both shortcuts are not configured in KDE and both work in other applications. Can anyone reproduce? -

Both work for me (Windows+Ubuntu/Unity).

@Patrick-Fromberg said in Qt Creator Search and Replace:
I am using > 30 extensions and I do not know which ones are standard and which ones not.
The obvious thought is: is there a simple way to try disabling all these extensions in one go, and see if it makes any difference to your issues?
-
@JonB , good point. Do you know by any chance where they are stored so I can restore my previous state?

@Patrick-Fromberg
Unfortunately not, because as I said I don't really use QtCreator, and if I do I don't have any plugins! However a quick Google gives, say, https://doc.qt.io/qtcreator/creator-faq.htmlYou can disable the Qt Creator plugins, at the expense of losing functionality:
Launch Qt Creator from command line, with the -noload QmlProfiler -noload QuickDesigner arguments.
Disable the plugins permanently by selecting Help > About Plugins.
or https://doc.qt.io/qtcreator/creator-cli.html, ah ha there I see:
-noload allDisables all plugins.? So you don't have to move them, you can just run up a session without loading any?
-
@JonB , thanks, I did not know
qtcreator -noload all -load Core -load CppEditor. Unfortunately it did not solve the problem but it was worth a try.But I believe I know a bit more now about the Help problem. "Blocked by extension" probably refers not to a QtCreator extension but to a browser extension hence not really anything to do with QtCreator.
-
@aha_1980 , are you using KDE or something else?
-
-
Ok, QtCreator passes
Ctrl+F3to KDE for desktop selection while other applications capture that shortcut for themselves (Kate for e.g.). When I disable the shortcut in KDE, then it works in QtCreatorRegarding Search&Replace with selection scope, it is sadly not supported for Advanced Search. I probably remembered wrongly that it once worked. This is really strange because search and replace in a selection is a really common task.

I'm not sure why you need the advaced find for that if it works with normal search&replace? Symmetry?
Otherwise, creating a suggestion for that is easy to do ;) - please post a link here if you do so.

@aha_1980 No, normal search&replace does not work with regular expressions. But I can actually do search and replace with regex limited to selection scope if I use FakeVim.

It does. Hint: the small icon in the left corner of the search text.
