How to delete all comments in a script?

[carno]

I know how to extract a comment section in an AHK script:

Code: Select all

RegExMatch(script, "s)/\*(.*?)\*/", match)
MsgBox % match

However, I would very much appreciate if someone let me how to (write a script to) completely delete all comments (/* ... */) in a given script and come up with a script with no comments.

I found my answer here: https://www.autohotkey.com/board/topic/72415-script-ahk-no-comments/

theres more to parsing comments than just checking /* and ;, particularly if u actually care about not mangling the script in the process
u may be able to rip ahk2exe's guts and repurpose them https://github.com/AutoHotkey/Ahk2Exe/blob/master/ScriptParser.ahk#L33-L175

I agree. Both above scripts seem to mangle if not careful.

a small basic example to begin , should keep lines 01-14

Code: Select all

B:="/*", E:="*/" ,Z:=""
;---------------
gosub,a1
Loop,parse,e4,`n,`r
 {
 x:= A_LoopField
 x=%x%
 stringmid,p,x,1,1
 if (p=";")
   continue 
 If InStr(x,B)
   H1=1
 If InStr(x,E)
   {
   H1=0
   continue
   }
 if (H1="1")
   continue
 z .= x . "`r`n"
 }
msgbox,%z%
z=
return
;----------------------

Thanks, garry! I still remember your great and original YouTube contributions.

[garry]

@carno thank you , I just know basics , I learn from professional scripters here in ahk-forum
I was lost because youtube always changed , I use yt-dlp.exe , ffmpeg additional needed to download m3u8 file in same folder or for MP3
https://github.com/yt-dlp/yt-dlp#update
https://ffmpeg.org/download.html#build-windows
for youtube use like :
MP4 :
RunWait, %comspec% /k yt-dlp %url% --encoding UTF-8 -o "%foldername%\`%(title)s$`%(uploader)s$`%(id)s.`%(ext)s"
MP3 :
RunWait, %comspec% /k yt-dlp %url% -x --audio-format mp3 --audio-quality 320k --youtube-skip-dash-manifest --embed-thumbnail -o "%fdmp3%\`%(title)s$`%(uploader)s$`%(id)s.`%(ext)s" ;- needs ffmpeg.exe
or download a M3U8 file :
RunWait, %comspec% /k yt-dlp %url% -o %foldername%\%filename%.mp4 ;- needs ffmpeg.exe
