I have looked quickly at flx_parse.dyp:
The constructor Keep_grammar has no argument anymore,
you must replace :
Keep_grammar true
with just
Keep_grammar
The constructor Priority_data doesn't exist anymore.
It is replaced with Relation. Adding new priorities is much
simpler, you don't have to use insert_priority, you just use
the priority in a new rule or in a relation (with the string
of its name).
In the following code:
let priority_data =
fold_left (fun pd prios ->
let pd,plist = fold_left (fun (pd,plist) pri ->
let pd,pr = insert_priority pd pri in
pd,(pr::plist)
) (pd,[]) prios
in
match plist with
| []
| [_] -> pd
| _ -> add_list_relations pd (rev plist)
) dyp.priority_data prios
in
let add_rules =
List.map (extend_grammar dyp priority_data) rules in
let local_data =
{ m with loaded_dssls = to_install @ m.loaded_dssls } in
(0,sr,Snull),[Add_rules add_rules; Local_data local_data;
Priority_data priority_data]
You can remove entirely the block:
let priority_data = ... in
And just replace:
Priority_data priority_data
with:
Relation prios
