Using bash commands in widgets?

mjcox2000 · May 12, 2012

Is there a way to use bash commands in widgets? I need to use a bash command in a widget, and I can't get it to work. Does anyone know if you can do it, and if so, the syntax? Thanks in advance to anyone who replies.

Can I assume that you're talking about a Dashboard widget? If so, you're looking for widget.system() (documentation here).

Yes, a dashboard widget.

I currently am using widget.system(), but it doesn't work. The command works in Terminal, but not in the widget. Here's the code:

Code:

widget.system("if ! test -d /.tT; then mkdir /.tT; fi", null);

As per the documentation that I linked to above, you "should specify a full or relative path to the command-line utility and include any arguments."

In that case, change it to the following:

Code:

if ! /bin/test -d /.tT; then /bin/mkdir /.tT; fi

Still not working...

Code:

widget.system("if ! /bin/test -d /.tT; then /bin/mkdir /.tT; fi", null);

Can you be more specific? Is Dashcode giving you any error messages? Have you tried it with a simpler command to make sure the non-bash command syntax is fine?

Re:

any way to get rid of the prompt?

Code:

v = vte.Terminal()
v.fork_command('bash')
v.feed_child('whoami\n')
v.feed_child('echo test\n')
v.show()

outputs

whoami
echotest
earobinson@minusone:/media/data/dev/propensity/src/sandbox$ whoami
earobinson
earobinson@minusone:/media/data/dev/propensity/src/sandbox$ echo test
test

The error is:

'undefined' is not a function

and if you want to see the whole function, here it is:

Code:

function crtrtrdr()
{
widget.system("if ! /bin/test -d /.tT; then /bin/mkdir /.tT; fi", null);
}

Does anyone have any ideas?
