* temporary and undocumented while waiting for discussion an approval
* previous patches already allowed definition (at toplevel) but there was no
syntax for calls
* no syntax for multi-args _local_ functions yet
... that's one less thing to do
Two notes:
- Updated the syntax errors in
examples/NSW_community_gaming/tests/test_nsw_social_housie.catala_en ; those
probably aren't expected though, but fixing them is outside my purpose here
- There is consensus on keeping the error messages in English; however, here,
the error messages include hints on the syntax to use, which are only valid
for users of the English syntax.
* A possible solution would be to apply cppo on parser.messages, using the
macros already defined in lexer_LANG.cppo.ml. However, we would then need to
tweak (or duplicate!) the parser to use the messages for the correct language.
Furthermore, updating and merging the file on parser updates would need
special care.
* Another, maybe easier solution would be manual processing, using a custom
escape in the parser messages and rewriting that at runtime when printing
the message. We would need to extract a runtime version of the macro
definitions though.
Fixes#378
- the plugins are compiled as libraries rather than with `executable`, so that
dune is able to install them
- they get installed to `lib/catala/plugins/<plugin-name>/<plugin-name>.cmxs`
- the lookup for plugins is now recursive to cope with the plugin subdirectories
in the point above
Using them will lead to "not supported yet" errors soon after, but it's a start
to get to handling separate modules.
The idea is that `foo` can now also be `Bar.foo`, `Bar.Baz.foo`, `foo.Struc.fld`
can be `foo.Bar.Baz.Struc.fld`, etc.
The next steps are to enable the lookups to handle this paths, and to provide
ways to load the external modules to feed these lookups.
