1. Ed.bat won't open file
I've just noticed that with Eu3.1 ed.bat can't open my file (eg MyProg.exw)
which is in a folder whose name contains a hard space (eg c:\Eu Projects);
so when I try to open c:\Eu Projects\MyProg.exw I see my source code in the
editor's window (under c:\Windows\system32\cmd.exe), but then can't run it.
I receive an error message: "Can't open c:\Eu.exu"
It seems unable to recognise the space in the folder's name, because the
problem disappears when I rename the folder to c:\EuProjects\...
Is this the expected behaviour? Is there a way around it?
I'm using XP. "EUDIR = c:\Euphoria" and "PATH = c:\Euphoria\bin;"
Thank you

It shouldn't show ".exu" as the extension.
That's a new bug in 3.1 that has been reported already (See SourceForge).

You might be using a version of ed.bat that runs ex.exe,
rather than exwc.exe, so it doesn't handle long filenames very well.
If you type:
ex where ed.bat
at a command prompt, it should tell you which ed.bat it is picking up,
based on your PATH environment variable.
Have a look at ed.bat with ed or NotePad or something to see if
it has ex.exe or exwc.exe.
Perhaps you are picking up the old version of ed.bat that is
installed for pre-XP systems by the DOS/WIN installer.
If so, fix your PATH. I think if you fix this problem,
then the .exu problem won't happen.

Thanks Rob. I've done as above, and have reinstalled 3.1. My ed.bat says:
exwc.exe ed.ex %1 %2 %3
Still get the same behaviour: ie I have a source file on a path whose name
has a hard space (eg: c:\Eu Projects\MyProg.exw); I can open it with ed
after right-clicking on the file name; but can't run it by pressing Esc + e
Not to worry tho - it all runs properly from a command prompt if I use cd\
and type the pathname and filename myself, so no fuss. Just thought I'd
mention it in case I was overlooking something simple...
Thank you all the same.

OK, the fix for this is easy.
I added double-quotes around the filename for Esc e in ed.ex.
(.ex and .exw files).
I changed ed.ex (line 1795) to read:
if platform() = LINUX then
shell("exu " & file_name)
elsif match(".exw", lower(file_name)) or
match(".ew", lower(file_name)) then
shell("exw \"" & file_name & "\"")
else
shell("ex \"" & file_name &"\"")
end if
I'll test the double-quote fix on Linux later today
and check in the change.
