ale_call

ale_call is an Erlang interface module to the Aleph Rust compiler. It facilitates code generation from Aleph ASTs by converting Erlang terms to JSON and invoking the Aleph Rust binary.

Features

• Convert Aleph Abstract Syntax Trees (AST) into JSON format.
• Call Aleph Rust compiler executable directly or via Erlang ports.
• Configure the path to the Aleph Rust binary via API or environment variable.
• Specify output code type (default is ale) for flexible generation targets.
• Simple error handling with {ok, Result} / {error, Reason} tuples.
• Designed for easy integration in Erlang/OTP projects and Hex.pm packaging.

## Example

 1> AST = #{
         <<"type">> => <<"Add">>,
         <<"numberExpr1">> => #{
             <<"type">> => <<"Int">>,
             <<"value">> => <<"3">>
         },
         <<"numberExpr2">> => #{
             <<"type">> => <<"Int">>,
             <<"value">> => <<"4">>
         }
     }.
  #{<<"numberExpr1">> =>
        #{<<"type">> => <<"Int">>,<<"value">> => <<"3">>},
    <<"numberExpr2">> =>
        #{<<"type">> => <<"Int">>,<<"value">> => <<"4">>},
    <<"type">> => <<"Add">>}
  2> {ok, Code} = ale_call:generate(AST).
  {ok,<<"3 + 4\n">>}
