Title: How to find the full directory of a file ?
Post by: bitli on 2015 February 01 07:49:20

I need to get the full directory (with drive and whatever) of a file (this is to initialize the initialPath of FileDialog). It seems that on windows File.extractDirectory does not return the drive part.  Is there a method to get this information which is OS independent and does not rely on parsing the path ?
Thanks

Hi Bitli,

In previous scripts I used File.extractDrive(name) + File.extractDirectory(name). Seems to work on Win and Mac, don't know about other platforms.

In new script I am working on I don't bother, as PI seems to remember and use a directory by default most of the time. However if the saved directory no longer exists PI reverts to its install directory, which I find annoying. I wish PI would search up the directory path for an existing directory, and stop there. IMO this would save navigation time.

Thanks Mike, this will do (I will check on Windows)
This is to store the 'configurations' (rule sets) for FITSFileManager, so they are usually in a directory different from the images, so it would make sense to have a different default  I will see how it works,

The correct way to implement this is as follows:

Code: [Select]

function getDirectoryWithDriveLetter( a_path )
{
   let path = File.windowsPathToUnix( a_path );
   return File.extractDrive( path ) + File.extractDirectory( path );
}
This function is portable to all supported platforms. A drive specification "<u>:" will be included if it is present in the specified path. UNIX directory separators "/" will be used on all platforms.
