I'm working with IntelliJ IDEA in a rather large tree of projects almost exclusively on about 5 folders nested deeply in the hierarchy. Ideally I just want to see those 5 folders most of the time - the other projects and the other folders in their projects are usually just visual clutter. How can I get a view as close as possible to this with IDEA?
I do want all projects accessible in my workspace, so I can't just throw away the others. And even that would not help too much, because those folders are deeply nested in their projects. The favorites view almost does what I want, since you can unfold the folders there - but if there are some new files they are often not visible there (not sure whether this is a bug or a feature). Do you have other ideas? Thank you very much!
It depends on what you are trying to do. You can create scopes by criteria.
Go to preferences (mac) -> appearance & behavior -> scopes
There you can create local and shared scopes. You can manually edit these or use a regex pattern. The current reference documentation is located here.
Here are some examples from the jetbrains website of using regex.
file[MyMod]:src/main/java/com/example/my_package//* - include in a project all the files from module "MyMod", located in the specified directory and all subdirectories.
src[MyMod]:com.example.my_package..* - recursively include all classes in a package in the source directories of the module.
lib:com.company..*||com.company..* - recursively include all classes in a package from both project and libraries.
test:com.company.* - include all test classes in a package, but not in subpackages.
[MyMod]:com.company.util.* - include all classes and test classes in the package of the specified module.
file:*.js||file:*.coffee - include all JavaScript and CoffeeScript files.
file:*js&&!file:*.min.* - include all JavaScript files except those that were generated through minification, which is indicated by the min extension.

Moving to intellij i'm trying to understand properly the logic behind the its project structure. I come from eclipse. After reading for a while i understood the relation between workspace and project, then between project and modules. However something that is puzzling me is the logic of the default project configuration in Intellij. Indeed, when you create a project there is an initial module which to a certain extend is equivalent to the Project itself. To be more precise, the initial module folder is the Project folder. This is kind of confusing to me. Then when you add more module they are sub-module of that module.
My first question is what is the rationale of making this first module equivalent to the project folder ?
Following this, i would further ask, what the point of having modules as sub-module of others.
In eclipse i use to have simply different project (i.e. module) independent from each other and adding the dependency as necessary. So how does the Idea solution makes it better, if not what is the rational here ?
I saw that one can start an empty project and then add modules to it. However in that case, the modules added are added as subfolder of the Project and therefore there is no initial module equivalent to the Project folder ? So why this difference and what is the rationale behind it ?
What would be the better approach, the first or second ?
Would it be ok to have this first initial module with no src or test folder but just with the proper facet so as to spread it to the sub-module?
I would appreciate if someone could explain a bit the rational of all of it ?
I will move to SBT soon (i.e. maven structure which I suppose inspired all modern IDE project Structure) if one want to explain within that context fine, nevertheless i want to understand the rationale in intelliJ first.
Many thanks,
-M-
PS: What i'm looking for is some advise for some multi-module project structure in Intellij as i'm moving my eclipse workspaces to it.
I think that it's not uncommon for projects to be relatively small, so they don't need fancy modules with dependency management etc. In that case, I find the default project created by IntelliJ to fit perfectly my needs: no need to add submodules, everything is directly in the parent project, it reduces the structure to its bare minimum.
On the other hand, big projects with submodules will likely resemble the structure of a Maven multimodule project (perhaps SBT too, but I don't know this tool at all). You have a parent root which acts as a container for submodules. The parent project may also store configuration (a default SDK, a language level etc. that will be inherited by the submodules). The actual code will be contained in the submodules.
Regarding your questions, it all depends on the kind of project you are developing. For a small codebase, you could keep a simple project with no submodule. For bigger codebases, you can either create modules manually, or import an existing Maven/SBT/whatever project, which will automatically create modules reflecting the imported structure.
I would like to add into project some files that shouldn't be compiled. I mean mainly text files with for example notes, concepts, comments etc.
I realized that it is possible only at module level. But it is not very convenient. I'd rather prefer to keep them on project level. Is it possible in any way?
And if not:
I have another idea: to create special module, name it for example "other_stuff", do not create src directory and put files there. Is it ok? I'm afraid of potential compilation problems when one of modules is artificial, with no sources but still has sdk assigned (it is probably impossible to leave module without sdk assigned).
While generating artifacts you can add any file into your artifact. Also, in modules you can have folders not declared as source, and they will not be compiled.
I am trying to clean up some of my projects, and one of the things that are puzzling me is how to deal with header files in static libraries that I have added as "project dependencies" (by adding the project file itself). The basic structure is like this:
MyProject.xcodeproj
Contrib
thirdPartyLibrary.xcodeproj
Classes
MyClass1.h
MyClass1.m
...
Now, the dependencies are all set up and built correctly, but how can I specify the public headers for "thirdPartyLibrary.xcodeproj" so that they are on the search path when building MyProject.xcodeproj. Right now, I have hard-coded the include directory in the thirdPartyLibrary.xcodeproj, but obviously this is clumsy and non-portable. I assume that, since the headers are public and already built to some temporary location in ~/Library (where the .a file goes as well), there is a neat way to reference this directory. Only.. how? An hour of Googling turned up blank, so any help is greatly appreciated!
If I understand correctly, I believe you want to add a path containing $(BUILT_PRODUCTS_DIR) to the HEADER_SEARCH_PATHS in your projects build settings.
As an example, I took an existing iOS project which contains a static library, which is included just in the way you describe, and set the libraries header files to public. I also noted that the PUBLIC_HEADERS_FOLDER_PATH for this project was set to "/usr/local/include" and these files are copied to $(BUILT_PRODUCTS_DIR)/usr/local/include when the parent project builds the dependent project. So, the solution was to add $(BUILT_PRODUCTS_DIR)/usr/local/include to HEADER_SEARCH_PATHS in my project's build settings.
HEADER_SEARCH_PATHS = $(BUILT_PRODUCTS_DIR)/usr/local/include
Your situation may be slightly different but the exact path your looking for can probably be found in Xcode's build settings. Also you may find it helpful to add a Run Script build phase to your target and note the values of various settings at build time with something like:
echo "BUILT_PRODUCTS_DIR " $BUILT_PRODUCTS_DIR
echo "HEADER_SEARCH_PATHS " $HEADER_SEARCH_PATHS
echo "PUBLIC_HEADERS_FOLDER_PATH " $PUBLIC_HEADERS_FOLDER_PATH
.
.
.
etc.
I think that your solution is sufficient and a generally accepted one. One alternative would be to have all header files located under an umbrella directory that can describe the interface to using the depended-on libraries and put that in your include path. I see this as being similar to /usr/include. Another alternative that I have never personally tried, but I think would work would be to create references to all the headers of thirdPartyLibrary from MyProject so that they appear to be members of the MyProject. You would do this by dragging them from some location into MyProject, and then deselecting the checkbox that says to copy them into the project's top level directory. From one perspective this seems feasible to me because it is as if you are explicitly declaring that your project depends on those specific classes, but it is not directly responsible for compiling them.
One of the things to be wary of when addressing this issue is depending on implementation-specific details of Xcode for locating libraries automatically. Doing so may seem innocuous in the meantime but the workflows that it uses to build projects are subject to change with updates and could potentially break your project in subtle and confusing ways. If they are not well-defined in some documentation, I would take any effect as being coincidental and not worth leveraging in your project when you can enforce the desired behavior by some other means. In the end, you may have to define a convention that you follow or find one that you adopt from someone else. By doing so, you can rest assured that if your solution is documented and reproducible, any developer (including yourself in the future) can pick it up and proceed without tripping over it, and that it will stand the testament of time.
The way we do it is to go into build target settings for the main project and add:
User Header Search Path = "Contrib"
and check that it searches recursively. We don't see performance problems with searching recursively even with many (10-15 in some projects) dependencies.
An iPad project I have been working on has become bloated with a huge number of files. The application is a prototype and we are considering ways to prevent this when we rewrite it.
One of the members of our team suggests dividing all of the components into separate Xcode projects which will be included in a master Xcode project.
Is this a good idea? What are the reasons, if any, to avoid dividing features/components/controls into separate Xcode projects?
You can add a subsidiary project file to a master project file in Xcode. Just choose "Add File" and add it. When Xcode builds the master it will build the subsidiary as well if needed.
I use a similar system. I often break a project into sub projects just so I can focus on and enforce encapsulation. I write the data model first, then add the app delegate, then specific UI elements. I add each project to the next in turn. This also allows me to go back and change things without as much risk of breaking.
Really, a properly designed objective-c app should be easy to decompose into multiple project. Ideally, all the components are so encapsulate that they don't need any others save the data model.
We have put some of the code in its own project, building a framework which we link against at some of the other projects. It's sometimes annoying that you won't see the implementation files of the framework code right away in another project (by cmd+clicking or cmd+shift+D, or whatever you do normally to navigate). Xcode will only show you the header, you'll have to open the other project and find your file there manually. Not a big deal, but if you look up the code often, it will bother you.
A real problem is that you change the scope of some operations. Stuff like "Find in project" will work on a different file set, which might not be what you want sometimes (trying to find where this method is called / key is used in your whole code, or something); well, there remains Finder / find, so it might be okay. Refactoring is not - all the renaming stuff just breaks, as it will change only the code of the current project, but not of projects referencing this one. If you change interfaces often, better avoid splitting up the project.
A good thing is that you will get less conflicts on your .xcodeproj files (if stored in a shared repository) as someone removing a file from project X won't create a conflict with someone else adding a target on project Y, which where previously the same .xcodeproj (not exactly sure this is a conflict case, but there definitely are some).
Now with Xcode4 you can create a workspace and add all your projects there. Only for documentation purpose :)
To view and modify subproject implementation files, you should add the sub projects directly into the main project.
1 step - Drag and drop the .xcode project files to main project.
2 step - Go to main project TARGETS - > Build Phases. Add subproject target in Target Dependencies. You can also add binary files in Link Binary With Libraries.
3 step - Add subproject source path to main projects header search path.
Go to main project - > Build Settings - > Header Search Paths (e.g $(SRCROOT)/../CoconutKit-master/CoconutKit/Sources )
An Xcode project can have any number of build targets within it, and you can arbitrarily group source files into folders. What makes you think that multiple projects are necessary?
I'm working with xcode and I have classes associated with other projects that I want to be included in new projects. I realize that the #import will do the job technically (although what should i do if it's out of the project root folder). But what do I do if I want to include the class "properly" --basically so i can double click and edit out of the main project window where you can see all your files and such.
I guess I'm just looking for the best and/or proper way to include/import (into the project) .h and .m files that I've already created outside of the current project I'm working on. Taking into consideration that I may want to modify the class from the original without subclassing. Hopefully this makes sense.
Thanks,
Nick
Xcode project file organization doesn't reflect the data files on disk. Files can be added to a project from anywhere in the file system. When you add the files, choosing not to copy the files to the current project's directory means that the original files are used. Selecting one of these files in Xcode for editing will alter the original file in that other project. When returning to that other project, Xcode will use the edited files in any further work.
This type of use can be quite handy while working on multiple projects with some shared code. Yet, it can also cause headaches for a versioning system.
Might be worth thinking about how to make the classes into a private framework - then you can import that as another dependency each time. Alternatively you could use a separate version control system location to store the shared classes and just check that out into the project folder.
