Hi,

I don't know if anybody is maintaining Jam at the moment, but...

The following rule produces surprising (at least!) results when the marked lines are interchanged:

rule split-path { local parent = $(<:P) ; if ! $(parent) { ECHO "split-path =" $(<) ; ###### return $(<) ; ###### } else { local p ; p = [ split-path $(parent) ] ; local b = $(<:B) ; p += $(b) ; ECHO "split-path =" $(p) ; return $(p) ; } }

ECHO [ split-path a/b ] ;
