Language Support: Dart

[udoprog]

Preliminary support for Dart has been pushed to genco:
https://github.com/udoprog/genco#language-support

Initial implementation could generate fromJson/toJson implementations for each type.

If you are interested in contributing towards supporting dart, please feel free to add a note in this issue.

Work in Progress

Reproto Branch: https://github.com/reproto/reproto/tree/dart - this is currently mostly a copy of the rust backend.
GenCo Branch: https://github.com/udoprog/genco/tree/dart Dart support now in a released version of GenCo.

TODO

• JSON support that passes the existing test suite. (PR: Initial support for JSON and Dart #62)
  • enum support.
  • type support.
    • Partial, the big missing piece is iterating over lists and maps and encode/decode the values.
  • tuple support.
  • interface support.
    • A number of big things have been solved when working on type support. But still some ways to go.
• Backend-specific documentation for Language Support.
• Running project integration tests. Done, since we now have a workdir.

Some notes on how the process of building a new backend works:

Install the Dart SDK from: https://www.dartlang.org/tools/sdk/archive
Note: You need to have the dart command in your PATH.

Make the appropriate changes to the backend.

Try to compile the backend with cargo build.

Update test suite with make update-suites FILTER=dart.
This will populate all the integration tests in the ./it folder using the backend, you can look at these files to see if they make sense.

You can do a quick test, and see if a file compiles with dart path/to/file.dart
