I wrote my first Applescript today and I thought it could be useful, so I decided to share it with you 
This script generates a random UUID and copies it to the clipboard.
set the clipboard to (do shell script "python -c 'import uuid; print uuid.uuid1()'")
I am playing with the JDK Javascript API (JSR 223) and I wanted to check out the replacement of variables in a String. Then I suddenly got this error:
javax.script.ScriptException: sun.org.mozilla.javascript.internal.EvaluatorException: missing ; before statement (<Unknown source>#1) in <Unknown source> at line number 1
After some reseach I found out, that my variables did contain invalid characters in my case the variable contained a -.
So the Regular Expression for valid Javascript variable names is:
[a-zA-Z_$][0-9a-zA-Z_$]*
It is also possible to use any unicode characters for variables, but of course this is not recommended.
