Description | Use the revMacFromUnixPath function to convert a LiveCode-style file path to the Mac OS file path format (for example, if you need to pass a pathname to an external). The revMacFromUnixPath function converts slashes (/) to colons (:), the folder-level delimiter for Mac OS pathnames. It also deletes leading slashes, so that pathnames are rooted in the volume name (the standard for Mac OS pathnames). It also adjusts relative pathnames. On Mac OS systems, absolute paths always begin with the name of the disk that the file or folder is on. On OS X systems, the startup disk's name does not appear in absolute file paths. Instead, if a file or folder is on the startup disk, the first part of the file path is the top-level folder that the file is in. If a file or folder is on a disk other than the startup disk, its absolute path starts with "Volumes", followed by the disk name. The OS X path convention is used by LiveCode, but the old Mac OS-style path convention is required by certain applications (such as AppleScript), even on OS X systems. If the convertOSX is true (or if you don't specify the convertOSX and the application is running under OS X), the revMacFromUnixPath function automatically converts absolute paths from the OS X standard to the MacOS standard, adding the startup disk's name to paths that are on the startup disk, and stripping the "Volumes" element from paths that are not on the startup disk. If the convertOSX is false, the revMacFromUnixPath function does not make these changes to absolute file path|absolute paths. LiveCode always uses the Unix pathname standard for cross-platform compatibility, and automatically converts pathnames to the correct standard for the current platform when executing commands. You need to convert the pathname only if you are passing it to another program or external. If you are using only LiveCode commands and functions, you do not need to convert the pathname, since LiveCode does it for you.
