So, in my progress with QuickCode, I decided to make a tiny language in JavaScript just to test my theory about how I will go about making QuickCode.

Basically, the only function in this mini language is "dialog."
Example:

Code:

dialog Hello

So this is the JS code I have so far for my parser:

Code:

dialogFunc = /^(dialog)\s(\w+)$/

function submitIt(myForm) {
if (dialogFunc.test(myForm.quickCode.value)) {
alert()
return false
}
alert("Invalid code!")
return false
}

Now, on the line

Code:

alert()

right under the if () statement, I want the alert to display the substring

Code:

(\w+)

of the regular expression as a string.

I need help on how to get the alert to do that!

Nevermind, I finally got it after experimenting for a while

Code:

alert(RegExp.$2)

I was overthinking it big_smile

This is very interesting. Does it work so far?

Well, this tiny little programming language that I posted above works. My main project is QuickCode, and there's more about it in another thread on the Advanced Topics forum (I forgot the link). The QuickCode parser itself is about 1/2 done now, as I am continually hampered with bugs. So overall, it's coming along nicely, but I've still got a lot of work to do. smile
