Use the libURLSetFTPListCommand command to get a simple list of files in an FTP directory.


A URL that ends with a slash (/) designates a directory (rather than a file). An ftp URL to a directory evaluates to a listing of the directory's contents. The format of a directory listing depends on which FTP command Revolution sends to the FTP server. You specify which command to use with the libURLSetFTPListCommand command.

If you specify LIST, directory listings are returned in the same format as the Unix "ls" command and include information such as permissions, owner, size, and last modification date as well as the name of each file or subdirectory. Use this format if you need the additional information about each item in the directory.

If you specify NLST, directory listings consists of a list of names of files and subdirectories, one per line, without the additional information provided in a LIST listing. Use this format if you need a simple list of files and don't want to parse the more complex LIST listing for the file names.

The list command is set to LIST when the application starts up.

Important!FTPservers are not uniform in their response to a request for a directory listing. Some servers may format directory listings differently from these descriptions. These are the most common formats, but they are not universal.

Important! The libURLSetFTPListCommandcommand is part of the Internet library. To ensure that the command works in a standalone application, you must include this custom library when you create your standalone. In the Inclusions section of the Standalone Application Settings window, make sure "Internet Library" is selected in the list of script libraries.

Note: When included in a standalone application, the Internet library is implemented as a hidden group and made available when the group receives its first openBackground message. During the first part of the application's startup process, before this message is sent, the libURLSetFTPListCommandcommand is not yet available. This may affect attempts to use this command in startup, preOpenStack, openStack, or preOpenCardhandlers in the main stack. Once the application has finished starting up, the library is available and the libURLSetFTPListCommandcommand can be used in any handler.
