2003-11-20 VI I just love smake. Mostly because I have tclsh across all the platforms I work on. I thought there was something called "Jam", but couldn't find it. In any case I like the simple smake to the more complex (and more capable) bras.
Some notes about smake follow. I have also emailed the author.
When a target doesn't exist but all the dependencies are up-to-date, smake doesn't run the rule, which is counter-intuitive. e.g.
target a { depend {b.o c.o} { link a [list b.o c.o] } }
Here you would expect that if a doesn't exist, but b.o and c.o are up-to-date, then the link will run. That doesn't seem to happen for me (I could be just using it wrong). In any case, to fix this here's what I added:
Just before this:
if {$update} { uplevel 1 $op uplevel 1 {set targetUpdate 1} }
in the proc "depend", I added this:
if !$update { set thistarget [lindex $SmakeTargetPath end] if ![file exists $thistarget] { dputs 3 "Target $thistarget hasn't been made yet, update" set update 1 } }
Hope this helps someone!
2003-11-20 VI : A possible cleaner way to do the set this target is to do it like this:
if !$update { upvar target thistarget if ![file exists $thistarget] { dputs 3 "Target $thistarget hasn't been made yet, update" set update 1 } }
2003-11-20 VI : stdout and stderr redirection doesn't work. I often write a command like
exec grep -n Error $logfile > errors.log
smake nicely renames exec and prints the line before executing, but in this case the redirection doesn't work. To fix that, I change:
eval "exec_old $args >@ stdout 2>@ stderr"
to just
eval "exec_old $args"
I'm not sure why the >@ and 2>@ are there. When would it be needed?
