<h2>Use as library</h2>
|
|
|
|
Import directly by <tt>open</tt>:
|
|
<pre>
|
|
concrete AppNor of App = open LangNor, ParadigmsNor in {...}
|
|
</pre>
|
|
No more dummy <tt>reuse</tt> modules and bulky <tt>.gfr</tt> files!
|
|
|
|
<p>
|
|
|
|
If you need to convert resource category records to/from strings, use
|
|
<pre>
|
|
Predef.toStr : L -> Str ;
|
|
Predef.fromStr : Str -> L ;
|
|
</pre>
|
|
<tt>L</tt> must be a linearization type.
|
|
|
|

|
|
<h2>Use as library through parser</h2>
|
|
|
|
Use the parser when developing a resource.
|
|
<pre>
|
|
> p -cat=S -v "jag ska åka till Chalmers"
|
|
unknown tokens [TS "åka",TS "Chalmers"]
|
|
|
|
> p -cat=S "jag ska gå till Danmark"
|
|
UseCl (PosTP TFuture ASimul)
|
|
(AdvCl (SPredV i_NP go_V)
|
|
(AdvPP (PrepNP to_Prep (UsePN (PNCountry Denmark)))))
|
|
</pre>
|
|
Extend vocabulary at need.
|
|
<pre>
|
|
åka_V = lexV "åker" ;
|
|
Chalmers = regPN "Chalmers" neutrum ;
|
