#
# 1. Copy file sshplus.py (this file) to /usr/local/bin
# 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 [email protected]
# 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 [email protected]

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

Copy of SSHplus from Anil Gulecha, modified to support some very basic menu nesting.

Doesn't currently support importing nested menus from sshmenu configuration.

Can you please update it for Ubuntu 11.10?
It doesn't show an icon in the notification area and it core dumps on refresh.
Thanks for youe effort.

It's working for me on Ubuntu 11.10 but using Gnome Shell, not Unity (so it's not the same notification area). Have you tried the lastest version from Anil's github repository (github.com/anilgulecha/misc)?

Yes, the latest version from Anil is working,
Thanks.

Link update: https://github.com/anilgulecha/misc

works on ubuntu 16.04
