KE version 4.2
Version 4.2 introduces a number of significant changes, as detailed below.
Other changes are listed in KEHOME/doc/version.rel.
The recursive commands:
copy subhierarchies to or from the concept cname and
the directory fsdir/cname. In order to accommodate the
ambiguous names typically found in filesystems, ke records
three names for each concept: shortname, rootname, classname.
shortname is the filename, e.g.: bin
rootname is the full path name, e.g.: /usr/local/bin
classname is the reverse of rootname, e.g.: bin\local\usr\
rootname is used as the unique concept name, and
shortname, rootname, classname are attributes of rootname.
Windows Explorer can be used to edit directory hierarchies:
See KEHOME/view/existent for the initial KE hierarchy.
This directory hierarchy was created with the command:
User-friendly methods for relations:

done
do save relation

done

od relname
from initial file
to final file

The hwalk command is now available to users:
do hwalk od action,cname,path doneThe hfocus list may now be used in the write command:
do write od $hfocus to outfile done
or
do write od concept:1, concept:2, … to outfile done
The command
do exit done
has been replaced by the control statement
exit
