Re: [OctDev] Providing alternative functions

[Per P. <per...@ma...>]

Hi,
I'm having a small (possibly two) problem(s) with target 
grace_octave_path.m in graceplot/Makefile on OS X.

grace_octave_path.m: grace_octave_path.m.in
         cat grace_octave_path.m.in | sed -e 
"s:@ALTMPATH@:$(ALTMPATH)/$(GRDESTDIR):" > grace_octave_path.m

In the file grace_octave_path.m @ALTMPATH@ comes out as "/" as if 
$(ALTMPATH) and $(GRDESTDIR) would evaluate to an empty string in the 
sed command.

A little fiddling gives the following:
1) % cat extra/graceplot/grace_octave_path.m.in | sed -e 
"s:@ALTMPATH@:$(ALTMPATH)/$(GRDESTDIR):"
Illegal variable name.
2) % cat extra/graceplot/grace_octave_path.m.in | sed -e 
"s:@ALTMPATH@:$ALTMPATH/$GRDESTDIR:"
Bad : modifier in $ (").
3) % cat extra/graceplot/grace_octave_path.m.in | sed -e 
"s.@ALTMPATH@.$ALTMPATH/$GRDESTDIR."
(Works as intended)

So, it seems that
(1) sed dissaproves of $(VARNAME)
(2) sed dissaproves : as delimiter
(since ':' was the path delimiter in OS 4 through 9, OS X sometimes has 
funny interpretations of : and / when used together)
(3) works fine on OS X, don't know if it is acceptable elsewhere.

FWIW, sed -e "s/@ALTMPATH@/$ALTMPATH\/$GRDESTDIR/" also works.

My knowledge of sed et al. is limited, so this is about as much info as 
I can provide on the problem.
