Hello!
It turns out that there's no easy way, now, to determine inside the makefile
whether the output is to tty or now.
the simple $(shell perl -e 'print 1 if (-t STDOUT)')
does not work, since anything inside a shell is sending output
to shell and not to tty!
I ended up doing this:
.PHONE: isatty.mak
include isatty.mak
isatty.mak:
@perl -e 'print "isatty:=",(-t STDOUT),"\n"' > $@
and this works but it forces an extra evaluation of makefile
and seems too complicated for a simple thing like that ...
How about a nwe function $(isatty [n]) - like isatty on file n?
Sounds OK?
