Facilitate reusability (function libraries)

[blackwinter]

• Allow Fixes to import functions from other Fix files (cf. Catmandu::Fix: "load fixes from another namespace with the use statement").
• Imported functions are available for use in the current Fix.
• Possibly allow importing into a different namespace to avoid name clashes.
• Possibly allow importing of other languages (e.g. Java and/or JavaScript; see Facilitate extensibility (polyglot programming) metafacture-fix#14).

use(path_to_fix)
use(path_to_fix, as: namespace)
use(path_to_java)

@blackwinter isn't this already solved with include, macro and your java support?

isn't this already solved with include, macro

Catmandu's use() statement works differently:

# this will look for fixes in the Foo::Bar namespace and make them
# available prefixed by fb
use(foo.bar, as: fb)
fb.baz()

# this will look for Foo::Bar::Condition::is_baz
if fb.is_baz()
   ...
   fix()
   ...
end

and your java support?

use(path_to_java) would probably be the correct way to make Java functions available. We're basically making everything on the class path available, just like in Metamorph.

cmd(“java Myclass”)
>> send the record as JSON to the
STDIN of the external command and
replace it with the JSON from the
STDOUT

perlcode(“mycommand.pl”)
>> run the my command.pl on the data
in the record
