Tehnical Details of Contributing

Architecture

A High-Level example, ./uniteai/contrib/example.py

Here's a feature that will start counting up inside your document, and just demonstrates how to build a new feature.

./.uniteai.yml

You specify what features should be included by adding their module path. For instance the following only allows the example feature:

modules:
  # - uniteai.local_llm
  # - uniteai.transcription
  # - uniteai.openai
  - uniteai.contrib.example

The one central .uniteai.yml holds all config that may apply to any feature.

# Example: `uniteai.contrib.example`
#
# a feature that counts up

start_digit: 13
end_digit: 42
delay: 0.4

./lsp_server.py > load_module

Only desired modules will be loaded. They will be loaded via 2 functions they must provide:

def configure(config_yaml):
    parser = argparse.ArgumentParser()
    ...
    parser.add_argument('--start_digit', default=config_yaml.get('start_digit', None))
    args, _ = parser.parse_known_args()
    return args


def initialize(config, server):
    # add an new actor to the `server`'s state
    server.add_actor(NAME, ExampleActor)

    # add commands to the `pygls` `Server`
    @server.thread()
    @server.command('command.exampleCounter')
    def example_counter(ls: Server, args):
        ...
        ls.tell_actor(NAME, actor_args)

./uniteai/contrib/example.py

This code stands for itself, more or less.

It includes:

• an Actor that can be communicated with via message passing.
• some code that streams edits via the ls.edits task runner
• def configure(...) and def initialize(...), needed by load_module to surgically include/exclude desired/undesired features at runtime.

This is not crazy ergonomic yet, because I don't know how people will use this library, and I don't want to prematurely abstract some class that gets in the way of future development.

So, instead of introducing some leaky abstraction, some internals remain laid bare.

Please give me feedback of your experience as you learn from this example, and we'll slowly tighten things up. I envision some dangerous way of writing features, alongside some "happy-path" feature class that abstracts away most of this and merely requires a user provide a generator function like:

def streaming_fn(highlighted_region_from_editor):
    for _ in whatever:
        yield intermediate_results

Actor Model

The internal pieces of this software communicate via the Actor Model, using the Thespian library.

Namely, they each run as there own separate threads, and they keep their own separate internal state. The only way to interact with an Actor is via mesage passing. For instance you can ask the Transcription actor to start transcribing, and if you ask twice in a row without stopping in between, it has to determine how it handles that.

Edits Handler

Actors do not directly edit the document. Instead, edit tasks are passed off to single edits thread which handles actually applying them.

For instance, a BlockJob can be sent off to the Edits queue to add some text in the block which this actor owns, demarcated by the start and end tags:

    job = BlockJob(
        uri=uri,
        start_tag=START_TAG,
        end_tag=END_TAG,
        text=f'\n{running_transcription}\n',
        strict=False,
    )
    edits.add_job(NAME, job)

Note this job is not strict. This means that it's ok if the edit applier thread fails to actually make this change. This is useful when streaming a response. Say 10 streamed edits have accumulated in the job queue. It's ok to skip the oldest 9 of them.

Right now edit.py accepts 3 classes of edits. This developer API should likely expand.

BlockJob: completely replace text within a block, demarcated by start and end tags.

DeleteJob: delete any region of the document (eg, clean up the start + end tags).

InsertJob: insert text anywhere (eg, place start + end tags).
