Uhh, why do we want a yacc parser for this?
What's wrong with :
proc option {name attrib} {
global Options;
lappend Options(list) $name;
foreach attrp $attrib {
set aname [lindex $attrp 0];
set aval [lrange $attrp 1 end];
set Options($name:$aname) $aval;
}
}
proc config_read {dir} {
set cfiles [glob -nocomplain $dir/*.kci];
foreach f $cfiles {
source $f;
}
}
