How do I extract just the filename or just the directory from an absolute path description?Using the example path: string $fullpath = "c:/maya/projects/default/sourceimages/myImage.tif" I use a few handy dandy utility procedures to deal with filepaths, filenames and the different slashes used for Windows vs. UNIX/Maya. The ‘ global proc string filepart( string $path ) // Extracts the path portion of an absolute filepath. // Input: e.g. "D:/projects/default/scenes/myScene.mb" // Result: e.g. "myScene.mb" // // Filepath can be delimited with // either slash ("/" or "\") { string $filepart = match( "[^/\\]*$", $path ); return $filepart; } The ‘ proc string pathpart( string $path ) // Extracts the path portion of an absolute filepath. // Input: e.g. "D:/projects/default/scenes/myScene.mb" // Result: e.g. "D:/projects/default/scenes" // // Note: Requires that the filepath be delimited with // _forward_ slashes ("/") { string $dir = match( "^.*/", $path ); int $sz = size( $dir ); // Strip off trailing '/' // if ( ( $sz > 1 ) && ( substring( $dir, $sz, $sz ) == "/" ) ) { $dir = substring( $dir, 1, ($sz - 1) ); } return $dir; } So, to get just the filename from the path description: string $file = filepart( $fullpath ); // Result: myImage.tif // And, to get just the directory from the path description: string $directory = pathpart( $fullpath ); // Result: c:/maya/projects/default/sourceimages // Related How-To'sThursday, September 07, 2000 | ||
