# 2. Edit file .sshplus in your home directory to add menu entries, each
#    line in the format NAME|COMMAND|ARGS
# 3. Launch sshplus.py
# 4. Or better yet, add it to gnome startup programs list so it's run on login.

_VERSION = "1.0"

_SETTINGS_FILE = os.getenv("HOME") + "/.sshplus"
_SSHMENU_FILE = os.getenv("HOME") + "/.sshmenu"

_ABOUT_TXT = """A simple application starter as appindicator.

To add items to the menu, edit the file <i>.sshplus</i> in your home directory. Each entry must be on a new line in this format:

<tt>NAME|COMMAND|ARGS</tt>

If the item is clicked in the menu, COMMAND with arguments ARGS will be executed. ARGS can be empty. To insert a separator, add a line which only contains "sep". Lines starting with "#" will be ignored. You can set an unclickable label with the prefix "label:". Items from sshmenu configuration will be automatically added (except nested items). To insert a nested menu, use the prefix "folder:menu name". Subsequent items will be inserted in this menu, until a line containing an empty folder name is found: "folder:". After that, subsequent items get inserted in the parent menu. That means that more than one level of nested menus can be created.

Example file:
<tt><small>
Show top|gnome-terminal|-x top
sep

# this is a comment
label:SSH connections
# create a folder named "Home"
folder:Home
SSH Ex|gnome-terminal|-x ssh user@1.2.3.4
# to mark the end of items inside "Home", specify and empty folder:
folder:
# this item appears in the main menu
SSH Ex|gnome-terminal|-x ssh user@1.2.3.4

label:RDP connections
RDP Ex|rdesktop|-T "RDP-Server" -r sound:local 1.2.3.4
