get application path directory

[giuseppefrattura]

hy,

i'm trying to create a plug-in that run an application located in the same directory of the plug-in file.

If i do

system("./Rec.app/Contents/MacOS/AlbumExpressRecord");

the application search the file in my home directory.

Is there a function in the SDK that say me wath is the path of Photoshop directory???

Thank you

sSPPlugins->GetPluginFileSpecification(pluginRef, &outFileSpec) from SPPluginsSuite is probably what you are looking for

[giuseppefrattura]

hy thank you for your asnwer.

i do this things:

I take the Dissolve project.

Modify the "PluginMain" adding:

    SPPluginsSuite* sSPPlugins;
    // Use the Basic Suite as describe in the chapter of that name
    // and to acquire the suite
    SPErr error = sBasic->AcquireSuite( kSPPluginsSuite, kSPPluginsSuiteVersion, &sSPPlugins );
    if ( error ) goto error;
    sSPPlugins->GetPluginFileSpecification(pluginRef, &outFileSpec);

and including at the top

     #include "SPPlugs.h"
     #include "SPAdapts.h"

but i've many compilation error.

1) sBasic is not declarated in this scope

2) pluginRef was not declered in this scope.

What can i do? What is my pluginRef?

Thank you!

I hope you can help me becouse  this plug-in is very simple, it must execute a file in the same  directory where the plugin is installed.

If i execute system("./Appname.app/Contents/MacOS/AppName"); the plugin search in my home directory (on windows and on MacOS).

i try to write:

     SPPluginsSuite* sSPPlugins;
        
     SPPluginRef fPluginRef = message->d.self;

    SPPlatformFileSpecification filespec;
    
     sSPPlugins->GetPluginFileSpecification(message->d.self, &fileSpec);
    
     filespec.mReference
    
     ai::FilePath path(platformFileSpec);
     std::cout << path.GetFullPath().as_Platform() << std::endl;

but i have several errors.

Thank you

What are the errors, specifically?

An FSSpec is the best we can do? Please tell me there's a way that doesn't use deprecated types and supports 64-bit? (Sorry, that's more of a rhetorical question to Adobe than directed at you).

#if __LP64__

typedef struct SPPlatformFileSpecification { /* this handles unicode file names */

FSRef mReference;

}  SPPlatformFileSpecification;

#else

typedef struct SPPlatformFileSpecification { /* Various things are casting this to FSSpec, so make sure the layout matches */

/** The version number. */

FSVolumeRefNum vRefNum;

/** The unique identifier. */

SInt32 parID;

/** The file name string.  */

StrFileName name;

} SPPlatformFileSpecification;

#endif

typedef struct SPPlatformFileSpecificationW { /* this handles unicode file names */

FSRef mReference;

} SPPlatformFileSpecificationW;

------------------------------------------------------------------------------

So I guess we only get modern types if we're 64 bits. I haven't touched an FSSpec in the last 8 years...

Hi guys,

i solve this problem.

This is the solution

#ifdef __APPLE__
        CFBundleRef mainBundle = CFBundleGetMainBundle();
        CFURLRef resourcesURL = CFBundleCopyResourcesDirectoryURL(mainBundle);
        char path[PATH_MAX];
        if (!CFURLGetFileSystemRepresentation(resourcesURL, TRUE, (UInt8 *)path, PATH_MAX))
        {
            //error!
        }
        CFRelease(resourcesURL);
        chdir(path);
        printf("Current Path: %s",path);      

#endif

Thank you for your help!!!

Ahh, I wondered about using NS/CFBundle, but wasn't sure.

If you're using Cocoa, that could pretty much be reduced to a single line:

#ifdef __APPLE__

    const char *path = [[[NSBundle mainBundle] resourcePath] fileSystemRepresentation];

     if (!path) {

            //error!

     }

     chdir(path);
     printf("Current Path: %s",path);     

#endif
