Text after #Region is not entirely considered a comment.

Recommended Posts

Posted (edited)

It is about the keyword #Region. In the SciTE help it says:

Quote

There is an additional folding keyword #region...#endregion to permit really large blocks of code to be compressed.  Any text following these special keywords is considered a comment:

But if I write #Region in the first line and write a space+underscore " _" at the end of the line, the compiler considers it a line continuation character. Is this a bug?

This only occurs in the first line of a script! If I write a blank line in front of it, it does not happen and the script runs without errors.

To test this example insert it into the first line of an Au3 script.

Spoiler
#Region Bug only occurs when #Region is in the first line _
Func Example()
  MsgBox(0, "", "hello")
EndFunc
#EndRegion

Example()

 

Currently I have written a function to read function heads from an Au3 script and format them in syntax notation. I discovered this behaviour when I wanted to remove the lines with #Region/#EndRegion and #Region was in the first line of a script.

My guess is that it could be a RegEx pattern. I had used this pattern first and made many attempts to fix it.

$sData = StringRegExpReplace($sData, '(?i)\n\h*(?:#Region|#EndRegion)(?!\w)[^\n]*\n', @LF)

Unfortunately, my RegEx skills are not good enough to change the pattern to make it work or to make such a fancy pattern. So I wrote a simple pattern that seems to do the job.

$sData = StringRegExpReplace($sData, '(?mi)^\h*(?:#Region|#EndRegion).*\R', "")

Can anyone confirm this, or have I done something wrong?

Bernd.

I would say yes, but this is very rare it should happen as not many people use any Directive (#) on line one and an normal syntax line on line 2.

so it is not just with #region but also with #xyz, where AutoIt3 should ignore any line starting with # and not being a Directive it knows like #cs/#ce.

I confirm that behaviour.

So yes, since it specifically says any text after it is considered a comment, it looks like a bug to me.

You can submit it here https://www.autoitscript.com/trac/autoit

I agree. I only discovered this because I also considered absurd constellations to secure my feature. Everything that AutoIt allows can be done by the user. :D

Thanks for the link. I'll try to see if I can do that.

 

Thank you both for your answers! :)
