cccc plugin
« on: November 12, 2009, 02:37:55 pm »
I am currently working on a small cccc plug-in.

The plug-in will issue a 'wxExecute' to have the cccc executable to it's thing.
I am observing a few strange things.

But first :
assumption : the starting working directory is the directory where the .cbp file is of the active project.

When I run command I want the plug-in to execute in the project directory it works.
Works meaning in this scenario :
* it finds the files specified on the command line (that is a list of ProjectFile::relativeFilename 's)
* it creates an output directory (.cccc, or when I specify a directory, my directory specified)

This is for example my command in the project directory :

Code: [Select]
[email protected]:~/Projects/Traficon/view_vipnt_buildserver/vipnt/Codec/Project> cccc --outdir=ldc "../inc/CodecP.h" "../src/Codec.cpp" "../src/Codec.h" "../src/CodecDecoder.cpp" "../src/CodecDecoder.h" "../src/CodecDisplay.cpp" "../src/CodecDisplay.h" "../src/CodecP.cpp"

or

Code: [Select]
[email protected]:~/Projects/Traficon/view_vipnt_buildserver/vipnt/Codec/Project> cccc "../inc/CodecP.h" "../src/Codec.cpp" "../src/Codec.h" "../src/CodecDecoder.cpp" "../src/CodecDecoder.h" "../src/CodecDisplay.cpp" "../src/CodecDisplay.h" "../src/CodecP.cpp"


However when this command is executed through wxExecute from the plug-in (NOTE :tested on LINUX) :
Then cccc can't find the files, when I remove those " , then it can find the files.
But in any case it will never create the output directory (and place the report files in it).

What would make it behave so different ?


Follow up : Anyone already can tell me how I can launch the CB html viewer, (the one which kicks in when you click the url at the bottom of the build log after a build), this would help me a lot otherwise I have to go hunting in the code ;-)   ?

I just created a small test-program and run its own code through cccc, works fine here.

By the way: I only tested it with synchronous execution.

Here is my example code:
Code: [Select]
void testFrame::OnExecute(wxCommandEvent& event)
{
    wxArrayString output, error;
    wxString cmd = _T("cccc --outdir=ldc \"testApp.h\" \"testApp.cpp\" \"testMain.h\" \"testMain.cpp\"");
    TextCtrl1->AppendText(_T("Now executing: ") + cmd + _T("\n\n"));
    long result = wxExecute(cmd , output, error, wxEXEC_SYNC | wxEXEC_NODISABLE);
    if(result != 0)
    {
        TextCtrl1->AppendText(_T("error executing ") + cmd + _T("\n"));
    }
    else
    {
        TextCtrl1->AppendText(_T("Output of output-stream:\n"));
        for(unsigned int i = 0; i < output.GetCount(); i++)
        {
            TextCtrl1->AppendText(output[i]+_T("\n"));
        }
        TextCtrl1->AppendText(_T("\nOutput of error-stream:\n"));
        for(unsigned int i = 0; i < error.GetCount(); i++)
        {
            TextCtrl1->AppendText(error[i]+_T("\n"));
        }
    }
}

and the output:
Code: [Select]
Now executing: cccc --outdir=ldc "testApp.h" "testApp.cpp" "testMain.h" "testMain.cpp"

Output of output-stream:

It works for me too (without surrounding "") when I have a directory layout like this :

'MyProgram' directory containing the  sources and cbp file.


But it fails when I have a directory layout like this :
'MyProgram' directory
|
+Project subdirectory containing the cbp file
|
+src subdirectory containing source files (*.cpp/h)
|
+inc subdirectory containing exported headers (*.h)

Strange that the " still don't work for me.
And why in such a changed project structure this would make a difference, dunno at all ?
Other plug-ins work correctly on this (codestat, clearcase, ..)

I changed my directory-structure to:
Code: [Select]
.
|-- include
|   |-- testApp.h
|   |-- testMain.h
|   |-- wx_pch.h
|   `-- wx_pch.h.gch
|       `-- Debug_include_wx_pch_h_gch
|-- src
|   |-- testApp.cpp
|   `-- testMain.cpp
|-- test
|   |-- test.cbp
|   `-- test.depend
`-- wxsmith
    `-- testframe.wxs

and the command to:
Code: [Select]
wxString cmd = _T("cccc --outdir=ldc \"../include/testApp.h\" \"../src/testApp.cpp\" \"../include/testMain.h\" \"../src/testMain.cpp\"");
Execution working dir is "."

output is now:
Code: [Select]
Now executing: cccc --outdir=ldc "../include/testApp.h" "../src/testApp.cpp" "../include/testMain.h" "../src/testMain.cpp"

Output of output-stream:

As you can see, it still works.

Can you provide the code you use, maybe I find a problem, you did not see ("Two heads are better than one").

Extremely strange, I just tried it out on Windows : works OK.

I will commit my code later in our svn, and if this takes too long I will PM it to you.

2 heads are indeed better then 1.

It seems to crash when I use it on larger project (C::B debugger branch and my own project).
Does it work for you? If yes I'll try to find why it crashes.
The backtrace is meaningless, even I've used --enable-debug... :(

I'm using debugger branch r6019.

Also, where I need to look/read in order to learn how to make the "Html viewer" go into the editors notebook?
(most of the time I ignore long posts)
[strangers don't send me private messages, I'll ignore them; post a topic in the forum, but first read the rules!]

It's a known issue, caused by very long command-lines.
The exact length depends on the OS as far as I know.

I tried to make it read a file-list from standard input (after creating a temporary file holding the list of project files), but it crashed also.
I don't know if there is an easy solution (if any).


EDIT:
The same problem exists for the cppcheck-plugin.
