+"""ObexFTP Virtual FileSystem for Midnight Commander
Manipulate a cell phone's filesystem calling obexftp binary. This is a complete
user-mode solution, no kernel modules required (unlike SieFS or such). The
-script implements all commands of Midnight VFS, except for undocumented "run";
-but there are no runnable files in the cell phone. The script is written in
-Python because I love Python, the best of all languages, and I need to parse
-XML directory listings from obexftp.
+script implements all commands of Midnight Commander VFS, except for
+undocumented "run"; anyway there are no runnable files in cell phones. The
+script is written in Python because I I need to parse XML directory listings
+from obexftp, and Python is the best of all languages suited for the task ;).
The script requires Midnight Commander 3.1+ (http://www.ibiblio.org/mc/),
-Python 2.2+ (http://www.python.org/),
-OpenOBEX 1.0.1+ (http://openobex.sourceforge.net/)
-and ObexFTP 0.10.4+ (http://triq.net/obexftp).
+Python 2.3+ (http://www.python.org/),
+OpenOBEX 1.0.1+ (http://dev.zuckschwerdt.org/openobex/) and
+ObexFTP 0.10.4+ (http://triq.net/obexftp).
-Edit the script, and correct the shebang path, if your python is not in the
-/usr/local. Edit the full path to the obexftp binary (see below). Put the file
-in the /usr/[local/]lib/mc/extfs, and add a line "obexftp" to the
-/usr/[local/]lib/mc/extfs/extfs.ini.
+Edit the script, and correct the the full path to the obexftp binary (see
+obexftp_prog below). For mc 4.7+ put the script in $HOME/.mc/extfs.d.
+For older versions put it in /usr/[local/][lib|share]/mc/extfs
+and add a line "obexftp" to the /usr/[local/][lib|share]/mc/extfs/extfs.ini.
+Make the script executable.
-Create somewhere a transport file. The transport file can have any name, and is
+Create somewhere a transport file. The transport file may have any name, and is
expected to be a text file with at least one line defining the transport to
your device. Other lines in the file are ignored.
For the Bluetooth transport put there a line "Bluetooth CP:AD:RE:SS channel",
where CP:AD:RE:SS is the hardware address of the device you want to connect to,
-and channel is the OBEX File Transfer channel; you can discover the address and
-the channel for your device by using commands like "hcitool scan" and "sdptool
-browse".
+and "channel" is the OBEX File Transfer channel; you can discover the address
+and the channel for your device by using commands like "hcitool scan" and
+"sdptool browse".
+
+For the USB put the interface number: "usb interface".
For the TTY put the device name: "tty /dev/ttyUSB0".
For the IrDA: just put "IrDA" in the file.
-Now run this "cd" command in the Midnight Commander (in the "bindings" files
-the command is "%cd"): cd description#obexftp, where "description" is the name
-of your file. The VFS script uses obexftp to connect to the device and list
-files and directories. Please be warned that opening the VFS for the first time
-is VERY slow, because the script needs to scan the entire cell phone's
-filesystem. And there must be timeouts between connections, which don't make
-the scanning faster. Midnight Commander caches the result, so you can browse
-directories quickly.
+Now run this "cd" command in the Midnight Commander (in the "bindings" file the
+command is "%cd"): cd transport#obexftp, where "transport" is the name of your
+transport file. The script uses obexftp to connect to the device and list files
+and directories. Please be warned that opening the VFS for the first time is
+VERY slow, because the script needs to scan the entire cell phone's filesystem,
+and there are timeouts between connections, which don't make the scanning
+faster. Midnight Commander caches the result so you can browse and manipulate
+files and directories quickly.
+
+Please note that manipulating the filesystem using your phone's internal
+filemanager in parallel with the VFS leads to a disagreement between the VFS
+cache and the phone. It is not very dangerous but inconvenient. There is no way
+to clear the VFS cache in Midnight Commander and reread the filesystem. You
+have to exit the VFS (cd /, for example) and return back using cd
+transport#obexftp command. Sometimes even this doesn't help - Midnight
+Commander shows the same cached VFS image. Exit Midnight Commander and restart
+it.
+
+If something goes wrong set the logging level (see setLevel() below) to INFO or
+DEBUG and look in the obexftp-mcextfs.log file. The file is put in the same
+directory as the transport file, if it possible; if not the file will be put
+into a temporary directory, usually /tmp, or /var/tmp, or whatever directory is
+named in $TMP environment variable.
