Should i provide a different version for maverick and natty?

[leon.vitanos]

So i have an application that i have created a deb package which can be installed in both Ubuntu 10.10 and 11.04 with no problems. The only reason why i am thinking of providing a different version for maverick and natty is because in Unity the menubar is been shown on the panel and not in the window, because my app has standard width and height ( it cannot be maximized ) and because of that there is a space on the bottom of the window and it is a big ugly now( If u didn't understand what i said i can take some screenshots )

But this is only in Unity.. If you switch to Ubuntu Classic ( Gnome ), the menubar will be on the window and not in the panel..

So should i provide a version for ubuntu 10.10 ( including ubunu 11.04, ubuntu classic ) and one for the unity or keep one version for both 10.10 and 11.04 but considering that at unity the app will be a bit ugly? :-k

The application is 'wallch' which you can find in my signature as well.
Another problem is that now you cannot access the tray(when an application is minimized to tray). Only the indicators are shown :(

Maybe you could detect the environment and change behavior accordingly? I don't know how, but there's surely a way...

Execute popen on lsb_release -c

This outputs:


Codename: maverick


Then you do sscanf on "Codename: <whatever>"

Like this:


#ifdef __cplusplus
#include <cstdio>
#include <cstdlib>
#include <cstring>
#else
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#endif


int main(int argc, char* argv[])
{
char szRelease [100];


FILE* pPipe = popen("lsb_release -c", "r");
char psBuffer[256];
while( !feof( pPipe ) )
{
fgets( psBuffer, 256, pPipe );
}

pclose(pPipe);
printf("String: %s\n", psBuffer);
sscanf(psBuffer, "Codename: %s", szRelease);
printf("Ubuntu Version: \"%s\"\n", szRelease);
return EXIT_SUCCESS;
}



Which you can finalize like this:


#ifdef __cplusplus
#include <cstdio>
#include <cstdlib>
#include <cstring>
#else
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#endif



static char* getUbuntuVersion()
{
static char szRelease[100];
char psBuffer[256];

if(szRelease[0] != 0)
return szRelease;

FILE* pPipe = popen("lsb_release -c", "r");

while( !feof( pPipe ) )
{
fgets( psBuffer, 256, pPipe );
}
pclose(pPipe);


//printf("String: %s\n", psBuffer);

sscanf(psBuffer, "Codename: %s", szRelease);

//printf("Ubuntu Version: \"%s\"\n", szRelease);
return szRelease;
}



static float getUbuntuVersionNumber()
{
static float fRelease = 0.0f;
char psBuffer[256];

if(fRelease != 0.0f)
return fRelease;

FILE* pPipe = popen("lsb_release -r", "r");

while( !feof( pPipe ) )
{
fgets( psBuffer, 256, pPipe );
}
pclose(pPipe);

//printf("String: %s\n", psBuffer);

sscanf(psBuffer, "Release: %f", &fRelease);

//printf("Ubuntu Release: \"%f\"\n", fRelease);
return fRelease;
}


int isThisThisUbuntuVersion(const char* szVersionInQuestion)
{
char* szUbuntuVersion = getUbuntuVersion();
return !strcasecmp(szUbuntuVersion, szVersionInQuestion);
}


int main(int argc, char* argv[])
{
printf("Ubuntu Version: %5.2f\n\n", getUbuntuVersionNumber());

if(isThisThisUbuntuVersion("maverick"))
printf("Yes\n");
else
printf("No\n");


if(isThisThisUbuntuVersion("natty"))
printf("Yes\n");
else
printf("No\n");


return EXIT_SUCCESS;
}






Ubuntu Version: 10.10

Yes
No

Execute popen on lsb_release -c

no need for popen. just read
/etc/lsb-release
(or source it before execution)

[wmcbrine]

Yeah but you don't want to base it on the release, you want to base it on Classic vs. Unity.

Try this:


cat /proc/self/environ

Looks like DESKTOP_SESSION is the one value you need:
