FW: hugs & text editor

[Johan Nordlander]

Hi Martin,

I'm sorry for letting this slip my mind.  However, you're right that the
new version has a slightly different behaviour when it comes to the
editor settings.  In an attempt to handle file paths containing space,
Hugs Feb-2001 encloses the file name substituted for %s in the editor
string within double quotes.  This usually works just as intended, but
for UEdit that means that the setting

   -E"uedit32 %s/%d/1"

will result in an invocation command similar to this:

   uedit32 "C:\Program Files\Hugs98\demos\Calendar.hs"/13/1

That is, the line and column modifiers appear outside the quoted file
name, which is something UEdit doesn't seem to handle very well.  The
workaround would appear to be to set the quotes explicitly:

   -E"uedit32 \"%s/%d/1\""

but that has (until today!) just resulted in two layers of quotes, which
confuses UEdit even more.

However, today I've checked in a fix that suppresses the automatic
quoting when explicit quotes are in scope.  That seems to make UEdit
happy, i.e., using the setting above the resulting editor command will
look something like

   uedit32 "C:\Program Files\Hugs98\demos\Calendar.hs/13/1"

Explicit quotes around the editor name also continues to be an option,
if you want to specify a full pathname that contains spaces.

The fix will be part of the next Hugs release.  However, if you want to
get hold of it immediately (well, tomorrow...), you can check out the
latest Hugs sources using anonymous cvs and compile it yourself.  See
http://cvs.haskell.org/ for further directions.

All the best,
Johan
