Seeing all this negative energy in this thread I figured I should thank you and Canonical for all this work: CMake integration is just getting better and better. It has improved dramatically since I've used it first something like two years ago. Actually using QtCreator with CMake is quite enjoyable those days. Only minor bits are missing to turn CMake into the QtCreator's build system of choice - in my very subjective and personal opinion. "Minor bits" like editing the CMakeList.txt from wizards and the project explorer. Sadly they are not trivial to implement and not really needed in daily usage. Still they seem important for the final polish. So keep on rocking, Mathias ___ Qt-creator mailing list Qt-creator@qt-project.org http://lists.qt-project.org/mailman/listinfo/qt-creator

It must exist and already “be a cmake build directory”, at least. But even that might not be sufficient. All this only works if the user currently pretty much knows the correct build dir s/he wants to set, before fiddling around with the build directory setting. Situations where files could be generated at places where they shouldn’t: * User temporarily sets the value to an existing directory (like a common project root), and then uses the browse button or an external file browser to actually find out the right subdirectory. In that case the directory exists, but Qt Creator should not put any files there * User copies the path from an existing project into the line edit, to later change it from there to the correct one. In this case the directory exists and actually might *be* a “cmake build directory”, just for a different project. No files should be generated. In both cases it is perfectly valid for the user to “leave the line edit” before correcting the setting to its actual value.

Thats almost what my current patch is doing, it runs cmake in the background when you change configurations, always, without popping up the dialog. If you want to change arguments you can do so in the build settings. CMake will then be run automatically in the background when you leave the lineedit you changed your settings in. However this does create files without notice which is really a problem when for example you change the builddir many times, you might end up with n buildfolders on your harddisk. I think it would probably be possible to run cmake automatically when you finished editing a cmake file, because in that case you did not change any builddir settings. You can again say that there might be cases when new files are created on the harddisk, but only in the builddirectory you specified anyway so I think that should be acceptable, right? > > Now if the cmake dialog acted more like ccmake and let me change cached > options that might be useful: the only thing valid to do from the cmake > dialog in an existing build directory is change options that ccmake could > change for you, but since I only have access to the command line of cmake > this isn't convenient.

Also almost what the patch does, but what will not work of course is when you open the project for the first time and the project file is invalid, then you will only see the "root" project file.

Just my 2 Cents on the Cmake Plugin: If I edit a Cmake file, then the next time I build cmake runs and generates the build system files. I would like it if QtCreator would automatically pick up on that and update my project so I do not have to keep manually clicking the "Run CMake" menu. Or at least have this as an option. Also, as far as getting ALL your files into QtCreator I usually have a cmake variable where I gather all the sources, files, UI files, icons, documentation and all the for a give target and then that CMake variable is used in the add_executable() command. Then QtCreator finds and lists all my files in a nice hierarchy very well.

Re: [Qt-creator] Refactoring the CMake plugin
On question 3: When switching project configurations, if the build is at all out of date the first thing I'm going to do is re-run make anyway. The only other option that makes sense it to completely blow away the build directory and re-run cmake. I would go so far as making it an option to just run a full build anytime I switch my build configuration (default to true as it is what the user wants even though it violates some purists expectation that no files will be written). I find it very annoying to have this cmake dialog pop up when I open an out of date build, as I'm just going to hit run and wait for it to complete. So long as no build option is being changed, I want qt creator to write the files it needs and not bother me. Now if the cmake dialog acted more like ccmake and let me change cached options that might be useful: the only thing valid to do from the cmake dialog in an existing build directory is change options that ccmake could change for you, but since I only have access to the command line of cmake this isn't convenient. I'm not sure if the cmake cache files are in a stable format where it would be valid for qt creator to do this, but it would be ideal. One annoyance I have is once in a while an automated build fails, when I open qt creator it tries to run cmake, which fails because of a syntax error. There is no easy way to open the offending file in qt creator so I can fix the error(s). If you can do something about this I'd be grateful. At least I'd like it if an outdated project configuration could be used because that will have 95% of what I need. -Original Message- From: qt-creator-bounces+millerhenry=johndeere@qt-project.org [mailto:qt-creator-bounces+millerhenry=johndeere@qt-project.org] On Behalf Of Benjamin Zeller Sent: Wednesday, June 18, 2014 5:39 AM To: qt-creator@qt-project.org Subject: [Qt-creator] Refactoring the CMake plugin Hello, I'm working on up-streaming the changes I made on the CMake plugin for the Ubuntu SDK, this all slowed down in the last weeks because I was really busy with other tasks. https://codereview.qt-project.org/80708 https://codereview.qt-project.org/80709 https://codereview.qt-project.org/80710 These are the merge requests, but they still have lots of comments about how things should be done and unrelated changes ,which made me wonder if it would be better to start over and get a set of clean patches. But before I start doing that I would like to discuss how the plugin should work and how it should be implemented. There are 3 features I would like to get into the CMake plugin: 1) Registering new cmake instances / tools The idea is to provide a way for plugins to register their own cmake installation and I introduced a class called CMakeManager that will own all registered installations. Every registered cmake will be represented by a CMakeTool instance, that abstracts away how a specific cmake is invoked. To register them I can see 2 ways: a) using factories: Personally I like factories more, maybe the approach used by the toolchains would fit here too (QList Factory::autoDetect()). That would also require a UI in the settings dialog where the user can manage the available cmake tools and manually register them. b) provide a function called registerCMakeTool() in the CMakeManager that can be called by plugins. 2) Associating a cmake tool with a build Now that there is a way to have more than one possible cmake, there needs to be a way to control which cmake is used when building/creating the project files. a) By linking it to a Kit -> provide a CMakeKitInformation so the user can control which Kit uses which cmake tool b) By linking it to a build configuration -> a CMakeBuildConfiguration would either need to return a Core::Id specifying the cmake tool it wants to use, or the CMakeTool instance itself, so the IDE can use it to create the build files. The build configurations config widget then can provide a way for the user to switch between the cmake installations available. 3) Automatically running cmake in the background (Get rid of the "Run cmake" dialog) It would be nice if the user was not required to handle the cmake dialog every time he wants to change the build settings, cmake arguments or wants to switch between different build configurations. In my MR, a cmake run is automatically started every time the build settings are changed and when opening a unconfigured project the project configuration page is used. At first sight this is very similar to how qmake behaves and makes it easily possible to switch between multiple build configurations without the need for running the cmake dialog every time. But the difference of course

Re: [Qt-creator] Refactoring the CMake plugin
Hi Lorenz, I doubt that this will be possible: The project view is meant to visualize the structure of the build system, so it tries to stay true to how the things are organized there.it CMake unfortunately has basically one flat list of files that it considers as inputs, so that is what creator displays. For the same reason I doubt that you will get OTHER_FILES in Cmake. But then there is a new cmake 3.0 out that I did not yet look into. Maybe they extended it? I am not optimistic about that: These things are not strictly necessary to build (and are indeed mostly for IDE support) and so far the cmake authors did not show too much interest in supporting IDEs. Yes, they are willing to add new new generators so that IDEs can consume the results of cmake runs more easily, but from the little I heard there is little love for adding features that are not necessary to build files per se.

So you can just skip those kits when asking which ones the user wants to see his cmake project built with. >> In the cmake wizard you then need to have the user select a kit (one >> with a configured cmake) and off she goes. > Ah yeah we can make the cmake wizard just show Kits that actually have > a cmake set, > that would work also but requires more configuration from a user who > just wants to > use cmake without any fancy things.

That is why the KitInformation has methods for default values, for the initial setup and to fix it again in case something breaks:-) Please make sure to only add cmake to kits where that actually makes sense. E.g. if there is no way to deploy cmake built binaries to the device in question, then just leave out the cmake for those kits. A user is still free to configure those kits manually if he knows what he does.

Ok, sounds good to me, so how would you want to have the Kit to extend the environment?

Ah yeah we can make the cmake wizard just show Kits that actually have a cmake set, that would work also but requires more configuration from a user who just wants to use cmake without any fancy things.

We need to have a way for the kit to extend the environment anyway, so the environment variables should be covered by that functionality (to be written;-). CMake arguments, etc. can all be added in a script.

Yes, we should be flexible and allow users to do whatever they want, but we do not need to provide an UI for everything anybody may conceivably come up with. This is one of those things IMHO. > Also for example if you want to configure a special toolchain file, or > just for > identifying a special type of cmake in the sourcecode. There are different kinds of cmake? That is new to me.

Desktop ubuntu (is that even supported?) is a pretty normal desktop target, so why have a special type for that in the first place? And why bind that type to cmake? Why do you want to limit users to the cmake build system? For the phones and other stuff you have to have devices to talk to those anyway, so why not use the type of device as a identification?

Why do you need a default cmake? Just use the one from PATH if the user has none explicitly set (and there is one in PATH). In the cmake wizard you then need to have the user select a kit (one with a configured cmake) and off she goes. I have nothing further to contribute to the discussion about when to run cmake, so I will just cut out that part.

Well the idea here was to be able to , for example, set different environment variables or add cmake arguments on the fly if the specific cmake version needs that. I also heard from other people it would be nice if one could configure a cmake installation for example to add a preload cache script. Also for example if you want to configure a special toolchain file, or just for identifying a special type of cmake in the sourcecode. For example the ubuntu sdk plugin identifies Ubuntu SDK kits by checking if the cmake tool is of a special type. > >> 2) Associating a cmake tool with a build >> >> Now that there is a way to have more than one possible cmake, there >> needs to >> be a way to control which cmake is used when building/creating the >> project files. >> >> a) By linking it to a Kit >> -> provide a CMakeKitInformation so the user can control which >> Kit uses which >> cmake tool >> >> b) By linking it to a build configuration >> -> a CMakeBuildConfiguration would either need to return a >> Core::Id specifying the >> cmake tool it wants to use, or the CMakeTool instance itself, so >> the IDE can use it >> to create the build files.

Well thats not entirely true for the unconfigured project case, the NoTargetsPanel will pop up and the user can choose his builddirectory, only if he presses "Configure" the builddir for the current buildconfig is created and the project description files are generated. > >> At firs

We created kits to get this repetitive configuration out of individual build configurations into one central place. I would personally just add a CMakeKitInformation with the path to the cmake binary you need to call. No CMakeManager, no CMakeTool, nothing:-) > 3) Automatically running cmake in the background (Get rid of the "Run > cmake" dialog) I am not sure I like this. The Run CMake dialog makes it clear that we are going to write something to disk. There is just no way to run cmake that does not write something somewhere. We generally try to avoid writing files in places where that is not expected. If a user e.g. changes the build dir 100 times in Project mode between builds, then he should only see the 100th directory that is selected when he hits build, not the 99 directories before that. > It would be nice if the user was not required to handle the cmake > dialog > every time he wants to change the build settings, cmake arguments > or wants to > switch between different build configurations. > > In my MR, a cmake run is automatically started every time the build > settings are changed and when opening a unconfigured project the > project > configuration page is used.

I personally would not be opposed to not having the cmake dialog when switching back to an already configured build configuration with an already existing build directory. But then I am not the cmake maintainer and am not fully familiar with the code base nor the direction it is supposed to take.

[Qt-creator] Refactoring the CMake plugin
Hello, I'm working on up-streaming the changes I made on the CMake plugin for the Ubuntu SDK, this all slowed down in the last weeks because I was really busy with other tasks. https://codereview.qt-project.org/80708 https://codereview.qt-project.org/80709 https://codereview.qt-project.org/80710 These are the merge requests, but they still have lots of comments about how things should be done and unrelated changes ,which made me wonder if it would be better to start over and get a set of clean patches. But before I start doing that I would like to discuss how the plugin should work and how it should be implemented. There are 3 features I would like to get into the CMake plugin: 1) Registering new cmake instances / tools The idea is to provide a way for plugins to register their own cmake installation and I introduced a class called CMakeManager that will own all registered installations. Every registered cmake will be represented by a CMakeTool instance, that abstracts away how a specific cmake is invoked. To register them I can see 2 ways: a) using factories: Personally I like factories more, maybe the approach used by the toolchains would fit here too (QList Factory::autoDetect()). That would also require a UI in the settings dialog where the user can manage the available cmake tools and manually register them. b) provide a function called registerCMakeTool() in the CMakeManager that can be called by plugins. 2) Associating a cmake tool with a build Now that there is a way to have more than one possible cmake, there needs to be a way to control which cmake is used when building/creating the project files. a) By linking it to a Kit -> provide a CMakeKitInformation so the user can control which Kit uses which cmake tool b) By linking it to a build configuration -> a CMakeBuildConfiguration would either need to return a Core::Id specifying the cmake tool it wants to use, or the CMakeTool instance itself, so the IDE can use it to create the build files. The build configurations config widget then can provide a way for the user to switch between the cmake installations available. 3) Automatically running cmake in the background (Get rid of the "Run cmake" dialog) It would be nice if the user was not required to handle the cmake dialog every time he wants to change the build settings, cmake arguments or wants to switch between different build configurations. In my MR, a cmake run is automatically started every time the build settings are changed and when opening a unconfigured project the project configuration page is used. At first sight this is very similar to how qmake behaves and makes it easily possible to switch between multiple build configurations without the need for running the cmake dialog every time. But the difference of course is that there are files created when running cmake and the user does probably not know about that. --> A possible solution to this would be to open a dialog to change the build settings, but to run cmake automatically when switching between build configurations. This would make the user more aware of what is happening. So if anyone has some thoughts or comments about that, I really would appreciate the help :).
