Having suffer a problem debugging under Windows with Cygwin installed I
decided to dig a bit further. I loaded the gdbpicl source and had a look at
the pathname generation code. If this is actually tageted at Unix then I
believe the convention should be to escape control and non-printing
charaters in the pathname, ie. the path "/a/b c/d" should be modified to
"a/b\ c/c" according to Unix conventions. This would certainly fix the
problem for me windows and make things much more tranparent (like you
wouldn't have to worry about where your source was in a directory
structure).
In trying to test this mod I'm confused about how the debug inspector works.
It keeps giving me a popup to the effect '... cannot resolve...' name if the
name is anything other than this or one declared in the method. Have I
missed a setting somewhere?
Regarding the pathname stuff, I think this change should be made. For Unix
it's neutral, for windows it's a real bonus.
Thanx,
Al

Hi Allan,
Thanks for letting me know.
I have also put in a fix for this problem.
Instead of just escaping spaces in the filename, I have included other
special characters to escape as well. My fix is in
GdbDebugSession.setStartProgramName.
In addition to spaces, following characters are escaped:
~`!@#$%^&()+={}[];,\/:*?"<>|
I have checked in the code in CVS. You can get the fix by checking out
the most recent copy of GdbDebugSession.java from CVS.
I hope it solves your problem running GDBPicl on Windows. Let me know if
you experience any problem.
Thanks,
Samantha

Samantha,
Had a look - 2 comments:
1) The interpretation of the '\' char in the input string is ambiguous.
You can either treat it as a character to be escaped (as you have) or assume
the caller has already constructed a string with an escaped character in it.
In the latter case your code adds a newly escaped '\' to the string. I not
sure this what you want. I'm inclined to consider a '\' char in the input
string as being there on purpose and leave the next character alone.
2) I implemented a method rather than simply embed the code since this is a
generally useful utility. That's a matter of taste.
I'd be inclined to change as follows:
private String escapeChars=" ~`!@#$%^&()+={}[];,/:*?\"<>|";
StringBuffer buffer = new StringBuffer();
char[] mainProg = _mainProgram.toCharArray();
boolean escaped = false;
for (int i=0; i<mainProg.length; i++){
if (escapeChars.indexOf(mainProg[i]) >= 0 && !escaped ){
buffer.append('\\');
}
eacaped = (esacped)? false : (mainProg[i]=='\\' );
buffer.append(mainProg[i]);
}

Hi Allan,
I agree about the ambiguity of '\'. I will put in your recommended
changes.
Thanks
Samantha
