Best practice to import (into session) RGL modules?

[Alex]

Tutorials https://www.grammaticalframework.org/doc/gf-lrec-2010.pdf and https://www.grammaticalframework.org/doc/tutorial/gf-tutorial.html provide examples how to work with custom grammars that contain one or two files. But RGL contains dozens of gfo modules for the abstract syntax alone.

How should I load/import RGL modules into seesion? - should I issue import command simply for each of the modules (disregarding particular order - e.g. inheritance relation) or is there some particular order in which the RGL modules should be loaded? Or maybe I should load just one RGL abstract syntax module and it will bring with it all the other modules?

Tutorials are not giving examples for importing RGL and I am not sure whether it is good to repeat trial-and-error process before asking for the best practice?

Thanks!

Hello Alex,

The usual practice is to open Syntax and Paradigms. For instance

  concrete ApplicationEng of Application = open SyntaxEng, ParadigmsEng in {...}

Syntax gives access to all shared functions and structural words, whereas Paradigms gives the morphological functions of each language.

If you want to test the RGL in the GF shell, you can do

  import -retain alltenses/TryEng.gfo

which contains both of those modules, plus some more.

See

https://www.grammaticalframework.org/doc/tutorial/gf-tutorial.html#toc80

for the practices. The API documentation

http://www.grammaticalframework.org/lib/doc/synopsis.html

also gives examples, plus an up to date documentation of the RGL.

Regards

  Aarne.
