Any ways to warn me of misspelling by like "variables are not declared" etc?

[pk23]

I'm completely newbie about code and don't know if it's viable for interpreted language, so plz pardon me if I'm wrong.

I'm just a little discouraged b/c just debugged for half an hour and turns out the reason of a bug is misspelling the variable. like:

Code: Select all

startXHigh[b]t[/b]light := {key1: 320, key2: 20, key3:500, key4:500}
start := startXHighlight["key1"]
MsgBox, % start

The script just behave strangely and didn't report error.

Which editor can warn me this kind of error? I'm using SciTE4AutoHotkey and don't know if it can do this or not. I guess this is the exclusive advantage of compiled language, but maybe there's some ways?

Use the #warn directive. (Click on the highlighted word to see the documentation on #warn.)

Ty and sry for reply late. I just learned the #warn directive and may I ask one more questions?
After adding the #warn interpreter, AHK will also exam the #include file and report every one founded. Is there any way to make it only check the current script (without #include file)?

As far as I’m aware, #warn applies to the complete script without exception. You would have to declare all variables before use (which is good programming practice). For local variables in functions, use the local command to specify variables local to the function.
