Title: Code Completion only works for "::" ? (CB 8.02, Ubuntu 8.04)
Post by: chca on May 07, 2008, 11:18:34 pm

Hello,

I want to use Code::Blocks 8.02 on Ubuntu 8.04 (64-bit) and installed the official .deb-file (http://www.codeblocks.org/downloads/5). When I create an "empty project", add a file "test.cpp" and type this code:

Code

struct Foo
{
	int mNumber;
};

void main()
{
	Foo f;
	// my cursor is here ...
}

"Foo::" will show a popup with "mNumber", but "f." won't. With "Foo* f" and "f->" it's just the same. When I use include files, classes, etc. code completion also only works with "::".

My code completion settings:
* "Disable code-completion" unchecked
* "Disable SmartSense" unchecked
* "Case sensitive matches" checked
* "Display info when hovering ..." checked
* "Auto-select, if only one match" unchecked
* "Automatically launch when ..." checked, number is "4"
* "Maximum allowed code-completion matches" 16384
* "Fillup characters" (empty)
* "Keyword sets to additionally include" 1+2 checked, 3-9 unchecked
* "Delay for auto-kick-in when typing [. :: ->]" 500 ms

I tested the example on a different PC using Ubuntu 7.10 (32-bit) with the same result.

Thanks for any advice.

I had the same problem a few days ago with autocompletion of the wxWidget clases. Searching throw this forum I have found the solution.

Code::Blocks has a Search path for autocompletion, so you have to add the path of your "test.cpp" to that Search path.

Where is it?

Go to menu Settings->Compiler and debugger... and in the opened window: Global compiler settings->Search directories->Linker.

Click the "Add" button to add the path of your "test.cpp" and it should work.

I have tried this before posting here on Code::Blocks 8.02 on Ubuntu 8.04 64 bits (the same as yours) and it works fine for me.

also helps to hit ctrl-s for save, seems to update the auto-completion thingy.

@Ganbito: I can't imagine that Code::Blocks doesn't know where to find the files in the current project for parsing. And I doubt that it is useful to add a source path to the linker path list (do you mean "Project Properties -> C/C++ parser options -> Additional search paths"?). Nevertheless, I added "test.cpp" to both paths, but nothing changes.

@Barking_Mad: Saving does not work for me. Even not saving and restarting Code::Blocks.

The problem certainly is not that Code::Blocks doesn't find my symbols (due to bad path setup); the "::" operator shows a complete list of all members, so basically everything is parsed (even in wxwidgets projects, etc.). Just "." and "->" do not show the member list.

@chca: Like you, I can't image that, but I have tested that it works in that way.

Well, that you write "Project Properties -> C/C++ parser options -> Additional search paths" seems more apropiated for files within a project, but when I wrote I only remember global properties.

I meant path where "test.cpp" is found, not "test.cpp" itself, but when I wish to try that (during the writing of this post) it get working in the right way even without adding the related path to the Search path (even global or project settings) so I have no idea, but now it works as it was thinked to work. I deleted the previous global search path, started a new project and changed the struct name (struct Glass...) but it continued to work, so I don't know.  :?

Sorry, but I can't try to help you anymore.

Of course, I added the path and not the file; sorry for my inaccurate statement.

I've build Code::Blocks from source, but the same problem again.

Very interesting: With global variables, "." and "->" work fine (local variables in functions and member variables in classes don't work):

Code

struct Foo
{
    int mNumber;
};

Foo f1;

int main()
{
    Foo f2;
    // cursor is here
    return 0;
}

Code

struct Foo
{
    int mNumber;
};

Foo f1;

class A
{
    private:
        Foo f2;

    public:
        void test();
};

void A::test()
{
    // cursor is here
}

So "f1." will show the list, but "f2." won't. Very strange.

...not for me (see the image below).

Could you try one of the next nightlies? Probably this "bug" has been fixed. (There were quite some changes to CC... actually not related to your issue... but... who knows?! ;-)).

I checked out the latest svn version (5041), but there is no improvement. In order to find out if it has something to do with my ubuntu installation, I made a fresh install in a virtual machine (Ubuntu 8.04, 64 bit, DVD image) and installed nothing but
- all available security updates
- libwxgtk2.8-0 libwxgtk2.8-dev wx-common wx-i18n wx2.8-headers (and dependencies)
- g++ (and dependencies)
- codeblocks debs from codeblocks-8.02-amd64.tar.gz

Unfortunately, the issue is exactly the same as described above. What's wrong with my setup?

Something that I've found to work when creating a new project is to save everything then close codeblocks, and then when the project is reopened in codeblocks the code completion works.  I didn't modify anything as suggested above. F1 and F2 still do nothing but after typing 4 characters the code completion kicks in the same way it does when using windows.


Starting it with a command prompt and try to complete code -- I also pushed f1 and f2 which created the following output but upon reopening everything seems to work correctly.  When F2 was pressed it crashed.
