KiCad

Invalid regular expression

Asked by v4l3n 3b

Hello,
i don't know if this is a bug, or only my fault, so i will ask here before i make a bug report...
When I start KiCAD i get a lot
"Invalid regular expression '^.*\.gb[alops]$': brackets [] not balanced"
errors...

I have tried to make my own program with the same RegEx and mine worked fine. The error is in tree_project_frame.c at line 542:

        for( unsigned i = 0; i < m_Filters.size(); i++ )
        {
            if(reg.Compile( m_Filters[i], wxRE_ICASE ) == false)
                wxMessageBox(wxString::Format("Error Compile %s with File %s",m_Filters[i],aName));
            else
            {
                if( reg.Matches( aName ) )
                {
                    addFile = true;
                    if( i==0 )
                        isSchematic = true;
                    break;
                }
            }

        }
I've added a Message Box to check if the compile call fails, and it fails on the following expressions:
    wxT( "^.*\\.gb[alops]$" ), // Gerber back (or bottom) layer file
    wxT( "^.*\\.gt[alops]$" ), // Gerber front (or top) layer file
    wxT( "^.*\\.g[0-9]{1,2}$" ), // Gerber inner layer file

I compiled with wx2.9.2
KiCAD Working Tree 3545

I can't find any error...

Thanks in advance

No idea. The expressions look fine. You may have to compile wx using debug options, and
then actually step into that code with a debugger.

I just tested BZR r3551 on Windows with MinGW using wxWidgets 2.9.3 and I do not get the assertion when the regular expression was compiled. The files that matched the failing expressions you mentioned also showed up properly. You may want to get wxWidgets 2.9.3 a try.

I updated also, and now it works. Thx.
