Schema compiler for Avro
README
  • avro is the runtime library, should be reasonably small (depends only on camlzip)

  • avro-compiler can read a json schema and generate code from it

See some examples from the tests/ directory:

  • tests/records.json and tests/records_test.ml that use it.
    you can see what the schema compiler will produce:

    $ ./compiler.sh ./tests/records.json
    (* generated by avro-compiler *)
    
    open Avro
    
    module Str_map = Map.Make(String)
    
    let schema = "{\"type\":\"record\",\"name\":\"test\",\"fields\":[{\"type\":\"long\",\"name\":\"a\"},{
    \"type\":\"string\",\"name\":\"b\"}]}"
    
    type nonrec t = { a: int64;  b: string; }
    
    let read (input:Input.t) : t =
      (let a = Input.read_int64 input in
       let b = Input.read_string input in
       { a;b })
    
    let write (out:Output.t) (self:t) : unit =
      ((let self = self.a in Output.write_int64 out self);
        (let self = self.b in Output.write_string out self);
        )
    
    
  • similarly for tests/employee.json and tests/employee_test.ml that use it
