Code:
vfv(n) { ; vfv(n) : n - Name of function or variable : true if valid else false
   Return !RegExMatch(n, "^[^#$0-9@-\[\]_a-z-]{1,253}$")
}


Usage:

Code:
s := "#$0123456789@ABCDEFGHIJKLMNOPQRSTUVWXYZ[]_abcdefghijklmnopqrstuvwxyz8593751111111111111111111111111111111111111111111111111111"
   
#$0123456789@ABCDEFGHIJKLMNOPQRSTUVWXYZ[]_abcdefghijklmnopqrstuvwxyz8593751111111111111111111111111111111111111111111111111111(x) {
   Return x
}

%s% := s

MsgBox % vfv(s) . "`r`n" . %s%("abc")
MsgBox % vfv(v) . "`r`n" . %s%


As you can see, the parameters for a function name are equal to that of a variable.

good to have. I may use that at my project. But i do not like the name of the function. I prefer more "isValidName()".

At home i take a more detail look at this.

You are more than welcome to change the function name to whatever you wish, but I prefer ValidFunctionOrVariable(Name). I shortened to vfv(n).

Code:
 vfv(n) { ; vfv(n) : n - Name of function or variable : true if valid else false
   Return !RegExMatch(n, "[^#0-\[\]-]{1,253}") ; Would it be faster without the logical-not and circumflex?
}

msgbox % vfv( "ya;:as" ) ? "YES" : "NO"


fails.

try using more precise needles such as \x30-\x39 and such

I thought I cut those characters out while I was making the RegEx.. I will fix it in a few minutes.


Edit: Updated function to the following:

Code:
vfv(n) { ; vfv(n) : n - Name of function or variable : true if valid else false
   Return !RegExMatch(n, "[^#0-9@-\[\]-]{1,253}")
}

That is what I sift through to find bad ranges. I hope you can understand why I keep missing some. Laughing

Updated the code to:

Code:
vfv(n) { ; vfv(n) : n - Name of function or variable : true if valid else false
   Return !RegExMatch(n, "[^#0-9@-\[\]_a-z---]{1,253}")
   ; Hex needle: [^\x23\x30-\x39\x40-\x5b\x5d\x5f\x61-\x7a\x80-\x9f\xa1-\xac\xae-\xff]{1,253}
}

An ANSI table does not know which characters AutoHotkey does or does not allow into its functions and variables.

I would break the lines, but then the function in the example would not work. Anyway, it looks just fine to me in 1024x1280 and 768x1366.

...a really simple solution is to add about 5 lines (comment lines or blank lines) to the code so it auto-collapses...(a better solution requires me editing the sites code.js)...

...did you swap the numbers?...or is your monitor really in portrait?...(which would make you have more horiz scrolling)? Mine is 1280x720 & has horiz scrolling (1280 is horiz/x, 720 is vertical/y)...
