Hi all,

You need one *Button* and one *DirChooser* on your form
I have reduced code to the following to emulate this bug I am getting: -
'*********************************************************
Public Sub _new()
End

Public Sub Form_Open()
End


Public Sub Button1_Click()

Dim SDir As String
Sdir = DirChooser1.SelectedPath
SDir = Replace(SDir, " ", "\ ")

End
'*********************************************************

Run the program and it crashes Gambas every time.

Any ideas?

Thanks,

Charlie

Hi  Benoit,

It may, or may not, be good syntax but press F5 and Gambas crashes. You can not compile it because Gambas crashes.

The purpose of the code was to change "dir" string into a form tha BASH would accept from Shell command if there are spaces in the "dir" string.

I am not an expert in any of this. I am just tring to help by pointing this issue out. If it is a syntax error Gambas should detect this and not crash.

Regards,

Charlie.

Nothing special happens there. Can you make a project that crashes for me?

Yeah, I see what you're trying to do. You can use \\ to make a single \
as the \ is normally the first part of a special character constant
(e.g. \t makes a Tab character). I think you can just wrap file/dir
names with spaces in them in quotes for use in bash scripts.

Oh, and my Gambas doesn't crash with the code exactly as you had it. As
Benoit experienced, it just doesn't compile, same for me (compile error
is"Bad character constant").

Kind regards,

Hi Caveat and Benoît,

Thanks for the replys. I will try a workaround, and I am pleased it's
not a issue for anybody else.

Should you be interested I have created a desktop video of the problem
and supplied the code that causes my Gambas to crash. You will find the
files at http://www.cogier.com/gambas/.

I have found that "SDir = Replace(SDir, " ", "\ ")" will cause a crash
but "SDir = Replace(SDir, " ", "\\ ")" is fine.

Thanks,

Charlie

Hello Charlie,

I think you have this problem when the 'gb.qt4.ext' is not selected in the Preferencies -> Components.

Because this symbol depend on this component.

Hi Olivier Cruilles,

I have found a work around. As suggested earlier by Caveat using "// ". I
now have: -

*Public Sub Button1_Click()
Dim SDir As String

Sdir = DirChooser1.SelectedPath

SDir = "ls " & Replace(SDir, " ", "\\ ") & " > Temp.txt"
Shell SDir

End
*

The output to the shell is : -

*ls /home/charlie/This\ is\ a\ \ test\ directory > Temp.txt*

This even allows for more that one space in a directory name.

Thanks all for your help.

Charlie

This bug doesn't seem to apply to Gambas 3.4.1.
So, try to update.
