如何在Mac OS X的Notification Center中添加变量？

Question

I have managed to cobble this together:

You can run it in your Terminal, it is harmless, and will output results only to notification center:

osascript -e 'display notification "The url(s) are on your clipboard from Droppings.app" with title "Droppings has finished sharing your file(s)" subtitle "Some Some title"'

Ideally, I want to add pbpaste in the "Some title" section, but I get the literal string. I tried creating a variable, and yet still get the literal string instead.

I tried building the entire string up as one variable, which in the Terminal, echo'd out works, but in Notification Center, I get the actually literal variable as a string.

Suggestions?

Answer 1

I find this syntax quite easy rather than single-exited, double-double quoted contortions:

echo pbcopiedtext | pbcopy

echo display notification \"Message is $(pbpaste)\" with title \"Funky Title\"  | osascript

Answer 2

In the shell, anything within single quotes ( ' ) is taken verbatim. No substitutions are performed.

You can substitute the pasteboard contents into the string using something like this:

osascript -e 'display notification "The url(s) are on your clipboard from Droppings.app" with title "Droppings has finished sharing your file(s)" subtitle "Some title '"$(pbpaste)"'"'

I end the single quote, open a double quote (so the contents of the pasteboard will be considered part of the single argument even if it contains spaces), substitute the output of the pbpaste command, close the double quote, re-open the single quote, and resume with the rest of the string.

This works, except that if the pasteboard contents contains stuff that osascript (ie AppleScript) treats as special, like quote characters, that can affect how osascript parses the resulting text. To fix that, you'll have to escape the pasteboard contents to be safe against interpretation by AppleScript, which is beyond the scope of this question.
