CDL, Constellation Definition Language

Show all headers | View raw

Every program that runs on multiple files needs some way of specifying
which files to process, especially backup.  It would be nice if we had
some powerful, universal constellation definition language to do that.

You want to be able to specify rules and drives, dirs, trees,
extensions, regex names, inclusions, exclusions.  It should know what
to do with new files that did not exist at the time the constellation
was defined.

It might have a GUI way and stream way of specifying it.

It could be retrofitted onto legacy programs by writing an CDL utility
that either exports a list of files or invokes a program over and
over, each time with a file on the list.

Has anyone ever heard of such a thing, or had ideas on what the syntax
might look like so that no-programmers could use it too, at least for
simple specifications

thinks, etc., because we’re hard put to define these things.
