Qt Creator Search and Replace

Patrick Fromberg

@JonB , good point. Do you know by any chance where they are stored so I can restore my previous state?

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.html

You 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 all Disables 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?

Hi @Patrick-Fromberg,

As I wrote, Ubuntu Unity.

Ok, QtCreator passes Ctrl+F3 to 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 QtCreator

Regarding 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.

No, normal search&replace does not work with regular expressions.

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

@aha_1980 Oh yes indeed. Clicking the mini-magnifier gives me regex. Great!

Important tips:

In-Selection Search and Replace does not work on a partial line - you must have at least one newline selected (The selection overlapping into the next line even if no text is selected).
Regular expressions must be properly escaped if you wish to use the mode to find certain strings be sure to read up on regex, every symbol can be escaped to do normal text matches but you may just want to turn it off temporarily.
This is important for workflows and fast-paced usage: Go into your text editor options and find the search scope highlight colors, set it to something super-obvious. For me I went with black text on yellow background. This way you are never mistaken on just what is going to get replaced. This way, if I don't see the black-on-yellow test I know right off the bat its gonna be a whole-file search. Use your subconscious powers to your advantage :3
Finally, to clarify about regular expressions, they do in fact work (at least now they do) with selection-scoped searches unlike what it used to be. As long as the search scope is showing, the selection will be replaced.
Be sure to set the selected text highligting (not the search scope highlighting, the one that higlights every occurance) to something less distracting or your mind might confuse it with 'search highlight'. I see a lot of themes/styles can cause this, so be careful about that.
To review: 1) selection scope is based on the highlight, be sure to set it up (many themes set this to a not-so-useful setting, so check it) 2) use highlights to guide you and you'll soon be able to make decisions about searches without thinking based on why you see
