Feature request: detect unused global vars

[marius-sucan]

Hello!

Can you offer a manually invokable tool to detect and list unused global variables? You made detect unused functions, something like that.

Thank you .

Best regards, Marius.

There are some technical problems that can't be solved at the moment, but this is one of my goals.

Common bugs that must be informed

Source Code

; !! Unrecognized variable definitions
fn_exp(ByRef paramExp1) {
    paramExp1 := "EXP"
}

fn_exp(neko_bug1) ;use function ByRef defined variable
DllCall("someDllCall", "Int", neko_bug2, "UInt")
;                             ^ use function ByRef defined variable

; legal, but unrecognized, 
neko_bug3 .= 0
neko_bug4 += 0
neko_bug5 += 1

neko_bug6 += 1, days
neko_bug7++

;I just support discern variable-defined like:
a1 := 0
VarSetCapacity(a2, 10240000) 
Width := NumGet(a3, 8, "int")
Width2 := NumGet(&a4, 8, "int") ; or Cmd param startWith Out/OutPut like https://github.com/CoffeeChaton/vscode-autohotkey-NekoHelp/blob/master/src/tools/Built-in/CommandOutPut.global.test.ts
ControlGetPos, OutX, OutY, OutWidth, OutHeight, Control, WinTitle, WinText, ExcludeTitle, ExcludeText
;!! Note that there are parts that are considered variables, using the semantic-highlight


;!! variable references Ignored-Error
;   legal, but unrecognized, 
myPath := A_AhkPath
Run *RunAs "%myPath%" /restart "%A_ScriptFullPath%" ;https://www.autohotkey.com/docs/v1/lib/Run.htm#RunAs
;            ^^^^^^ Error1       ^^^^^^^^^^^^^^^^ Error2
;            ^try shift-F12 find-all-references
;            ^can not find this way
; i can not find "%varRef%" in legacy-string
MsgBox, "myPath is %myPath% `nA_ScriptFullPath is %A_ScriptFullPath%"
;                   ^^^^^^ Error3

"AhkNekoHelp.Diag.useModuleValDiag": true

or try it, but this is a test option .
This lint just support of this file has def-var and not using in this file, not support of all pack.

v0.0.23 "AhkNekoHelp.CodeLens.showFileReport": true

In ahk, there is no keyword to declare every variable like other languages, so it is very difficult for me to analyze whether the variable is defined or not, this is some work, hope it can help you.
