Re: [Qt-creator] SyntaxHighlighting + Bison/FLex
Hi Jeremy, That sounds more like a semantic highlighter to me. Have a look at SemanticHighlighter::incrementalApplyExtraAdditionalFormats in src\plugins\texteditor\semantichighlighter.cpp and the usages in the QML/JS and C++ semantic highlighter.

Re: [Qt-creator] Disabling auto-reload of qbs files
Hi Christian (Gagneraud), OK, I just realised that i'm using a custom build of Qtc, "Qt Creator 4.5.0-rc1 (4.4.83)" - built on the 18th of October. The reason being that Qt doesn't support Linux-x86_32 anymore, so I have to build it myself (I cannot switch to Linux-x86_64). So this might not help at having a stable QtC. I will first install a release build (4.4.1 tag) and see how it goes. Why? There won't be fixes to 4.4 anymore, as 4.5 is near the release. I'd continue with this version and provide as much info as possible to Christian (Kandeler). Perhaps its a regression? Then fixing it would be much appreciated by others also. Best regards, André ___ Qt-creator mailing list Qt-creator@qt-project.org http://lists.qt-project.org/mailman/listinfo/qt-creator

(Chances are it's somewhere else in Creator, as project resolving happens in its own thread and should thus not freeze the GUI). I have to say it's hard to reproduce, it's morning here, and my machine restarted overnight, so I've just run QtC and opened my project, and i cannot notice any slow down yet. As the day goes i will try to report the exact condition(s), but i think it has to do with: - Edit qbs (a build might be running) - kill build and save qbs - The qbs process kicks in - The "Scanning for tests" kicks in - The code model process kicks in - Hit build again (maybe while the test scan and code model are still running) Thinking further as i type this message, this could be actually a resource problem with my machine: "only" 4 cores, it's a VM (gnome/mir thingy) that has poor graphical performance (I had to disable some gnome settings). I'm constantly monitoring the CPU load, and I've notice that QtC is resource intensive (that might be due to the code model and test scanning). I would prefer to edit and save my qbs files as I wish, and then explicitly tell QtC to "re-run qbs". I think the auto-reload is very useful on small project, but is not desirable on big projects. It would be nice to have an option somewhere to control this behaviour. Any comment on this feature request? I'm sure I'm not the only one to be "hit" by this. Independent of the build system, there are certain cases where the "auto-reload" functionality is annoying, e.g. when you type in a new build directory (there is a delay, but it only helps so much). On the other hand, suppose you could switch that off via some hypothetical checkbox. If you then forget to manually reload, Creator will have an outdated view of the project, which may result in surprising behavior e.g. regarding the code model, in turn leading to bogus bug reports. That's not to be underestimated. I fully agree with you, but i feel comfortable with that. The reason being that, on this project, right now, i mainly do "qbs stuff" within QtC, my goal is to build this project with QtC and Qbs. At this stage, I do not really care about up-to-date code model (which takes quite some time) and the auto-tests (which takes quite some time too, but I've now disabled this plugin). I would say that the size of my project is very roughly similar to QtC's one. My Qbs files are actually not complicated, there's no crazy dependency, ... Basically my work flow is: - try to build - analyse build failure - tweak Qbs - rince and repeat Will see later in the day, if I can capture the scenario and i have the feeling that it's not due to my VM, I will create a ticket with all the necessary details. Thanks for your help, Chris ___ Qt-creator mailing list Qt-creator@qt-project.org http://lists.qt-project.org/mailman/listinfo/qt-creator
