get_config_string

I'm using Allegro 4.2.1 and functiom get_config_string does not work for me. All others do ( int, float ).
string s = get_config_string( "Vars", "LogPath", "Not Read" );
s == "Not Read"

and I'm sure that section and value exist in my cfg.file ( LogPath = log.txt )

Anyone has any advice? Can this be a bug? Thanks.

No, it isn't a bug. Try this code, though.

set_config_string("Vars", "LogPath", "set value");
string s = get_config_string("Vars", "LogPath", "Not Read");

As tell me what the value is.

Yes... It works now. s == "set value"
Well... I guess problem is in file... but I have no idea where

Could you please explain it to me?

Can you provide the file as an attachment?

Here it is
http://www.members.allegro.cc/mscava/setup.cfg
( File also as an atachment... )

EDIT:
I see no difference between text generated by set_config_string and text written manually to notepad. Even non-visible characters are the same. Anyone has any idea what's wrong?

EDIT2: And I've found out, that it's not gonna read even file into which was written by set_config_string. Pls... help me someone...

try that.

string s.c_str() = get_config_string("Vars", "LogPath", "Not Read");

Edit:
for a lot of allegro fountions the string must be converted to a char string

wow

Piccolo, that has nothing to do with the problem. And that would most probably crash the program.

I haven't done much work with the config routines. Try posting the relevant parts of your source.

Yes, when sending values in. But when assigning, string reads from char* just fine.

Here is my configuration function:

1void Setup ::
2SetupAllFromFile ( const string& path )
3{
4  CfgFile :: SetCfgFile ( path );
5 
6  string s = get_config_string("Vars", "LogPath", "Not Read");
7  Log :: SetOutputFile ( s );
8 
9  Log :: Write ( "WrapAll::Setup started initialization!" );
10 
11  Setup :: InstallDevices();
12 
13  Renderer :: RenderMode renderMode = static_cast <Renderer::RenderMode>
14    ( CfgFile::ReadInt ( "Gfx", "RenderMode" ) );
15  Renderer :: WindowMode windowMode = static_cast <Renderer::WindowMode>
16    ( CfgFile::ReadBool ( "Gfx", "WindowMode" ) );
17 
18  Renderer :: SetupScreen( CfgFile::ReadInt ( "Gfx", "ResolutionWidth" ),
19         CfgFile::ReadInt ( "Gfx", "ResolutionHeight" ),
20         CfgFile::ReadInt ( "Gfx", "ColorDepth" ),
21         windowMode, renderMode );
22 
23  Updater :: Start ( CfgFile::ReadInt ( "Game", "TimerSpeed" ) );
24 
25  FpsCounter :: Start( CfgFile::ReadBool ( "Misc", "ShowFps" ) );
26 
27  Font :: InstallFont();
28}

Everything gets initialized, only Log is associated with file 'Not Read'. Well it's the only string that is being loaded in this procedure, so I've tried even:

string s = get_config_string("Gfx", "ResolutionWidth", "Not Read");
Log :: SetOutputFile ( s );

But with the same result. Well... I'm attaching my Setup.cfg ( the file that is being read ), so someone else might try it.

I'm gonna do some more tests meanwhile... Hopefully I'm gonna find a solution.

Reading numbers etc work then? How does your CfgFile class look?

Yes. Reading numbers works.

Really simple wrapper. I want to to add functionality in the future...

class CfgFile
{
  public:
    static void SetCfgFile ( const string& path );

    static string ReadString ( const string& section, const string& name );
    static int ReadInt ( const string& section, const string& name );
    static float ReadFloat ( const string& section, const string& name );
    static bool ReadBool ( const string& section, const string& name );
};

And now source file:

1void CfgFile ::
2SetCfgFile ( const string& path )
3{
4  set_config_file ( path.c_str() );
5}
6 
7string CfgFile ::
8ReadString ( const string& section, const string& name )
9{
10  return string ( get_config_string( section.c_str(), name.c_str(), "Not Read" ) );
11}
12 
13int CfgFile ::
14ReadInt ( const string& section, const string& name )
15{
16  return get_config_int ( section.c_str(), name.c_str(), -1 );
17}
18 
19float CfgFile ::
20ReadFloat ( const string& section, const string& name )
21{
22  return get_config_float ( section.c_str(), name.c_str(), -1.0 );
23}
24 
25bool CfgFile ::
26ReadBool ( const string& section, const string& name )
27{
28  return ( static_cast <bool> ( get_config_int ( section.c_str(), name.c_str(), 0 ) ) );
29}

In the example I didn't used ReadString, so I'm sure the problem is not in my class.

Well... Anyone tried to use my setup.cfg wheter it works. Or even tried to use get_config_string wheter it is not a bug?

I've tested your file and it works for me. Also I'm using the get_config_string(); function many times in my custom project and never had problems with it.

It's probably bug in your code, sorry.
