From 616a90ef1c90fb176e83fb93d153a2c3336807c3 Mon Sep 17 00:00:00 2001 From: MuXinCG <202322130196@mail.sdu.edu.cn> Date: Mon, 16 Feb 2026 01:12:02 +0800 Subject: [PATCH] feat(channels): add unified channel framework with Telegram and Discord support Introduce the new channel unification architecture: - Core framework: base channel class, bus, consumer, channel manager, middleware, mixins, capabilities, formatter, retry, plugin system - Telegram channel implementation with bot token validation - Discord channel implementation with bot token validation - Refactored iMessage to use new base channel architecture - Updated CLI: /channel commands, serve mode, channel setup wizard - Updated onboard wizard to support multi-channel selection - Config settings for all channel types - Stream events: media attachment support, done event content field - Comprehensive test coverage for channels, bus, and manager --- .gitignore | 6 +- EvoScientist/channels/README.md | 552 ++++++ EvoScientist/channels/__init__.py | 41 +- EvoScientist/channels/base.py | 1016 ++++++++++- EvoScientist/channels/bus/__init__.py | 6 + EvoScientist/channels/bus/events.py | 52 + EvoScientist/channels/bus/message_bus.py | 96 + EvoScientist/channels/capabilities.py | 220 +++ EvoScientist/channels/channel_manager.py | 995 +++++++++++ EvoScientist/channels/config.py | 126 ++ EvoScientist/channels/consumer.py | 407 +++++ EvoScientist/channels/discord/__init__.py | 19 + EvoScientist/channels/discord/channel.py | 255 +++ EvoScientist/channels/discord/probe.py | 33 + EvoScientist/channels/discord/serve.py | 93 + EvoScientist/channels/formatter.py | 287 +++ EvoScientist/channels/imessage/__init__.py | 9 + EvoScientist/channels/imessage/channel_rpc.py | 352 ++-- EvoScientist/channels/imessage/serve.py | 366 +--- EvoScientist/channels/middleware.py | 814 +++++++++ EvoScientist/channels/mixins.py | 306 ++++ EvoScientist/channels/plugin.py | 226 +++ EvoScientist/channels/retry.py | 122 ++ EvoScientist/channels/standalone.py | 142 ++ EvoScientist/channels/telegram/__init__.py | 17 + EvoScientist/channels/telegram/channel.py | 289 +++ EvoScientist/channels/telegram/probe.py | 32 + EvoScientist/channels/telegram/serve.py | 81 + EvoScientist/cli/__init__.py | 2 +- EvoScientist/cli/_app.py | 4 + EvoScientist/cli/channel.py | 568 +++--- EvoScientist/cli/commands.py | 104 +- EvoScientist/cli/interactive.py | 142 +- EvoScientist/config/onboard.py | 241 ++- EvoScientist/config/settings.py | 96 +- EvoScientist/paths.py | 4 +- EvoScientist/stream/emitter.py | 2 +- EvoScientist/stream/events.py | 39 +- pyproject.toml | 11 + tests/test_bus_integration.py | 286 +++ tests/test_channel_comprehensive.py | 1545 +++++++++++++++++ tests/test_channel_manager.py | 166 ++ tests/test_discord_channel.py | 71 + tests/test_message_bus.py | 111 ++ tests/test_onboard.py | 80 +- tests/test_stream_state.py | 159 +- tests/test_telegram_channel.py | 68 + 47 files changed, 9450 insertions(+), 1209 deletions(-) create mode 100644 EvoScientist/channels/README.md create mode 100644 EvoScientist/channels/bus/__init__.py create mode 100644 EvoScientist/channels/bus/events.py create mode 100644 EvoScientist/channels/bus/message_bus.py create mode 100644 EvoScientist/channels/capabilities.py create mode 100644 EvoScientist/channels/channel_manager.py create mode 100644 EvoScientist/channels/config.py create mode 100644 EvoScientist/channels/consumer.py create mode 100644 EvoScientist/channels/discord/__init__.py create mode 100644 EvoScientist/channels/discord/channel.py create mode 100644 EvoScientist/channels/discord/probe.py create mode 100644 EvoScientist/channels/discord/serve.py create mode 100644 EvoScientist/channels/formatter.py create mode 100644 EvoScientist/channels/middleware.py create mode 100644 EvoScientist/channels/mixins.py create mode 100644 EvoScientist/channels/plugin.py create mode 100644 EvoScientist/channels/retry.py create mode 100644 EvoScientist/channels/standalone.py create mode 100644 EvoScientist/channels/telegram/__init__.py create mode 100644 EvoScientist/channels/telegram/channel.py create mode 100644 EvoScientist/channels/telegram/probe.py create mode 100644 EvoScientist/channels/telegram/serve.py create mode 100644 tests/test_bus_integration.py create mode 100644 tests/test_channel_comprehensive.py create mode 100644 tests/test_channel_manager.py create mode 100644 tests/test_discord_channel.py create mode 100644 tests/test_message_bus.py create mode 100644 tests/test_telegram_channel.py diff --git a/.gitignore b/.gitignore index a3548d1..a01ec14 100644 --- a/.gitignore +++ b/.gitignore @@ -15,6 +15,8 @@ build/ .venv/ venv/ uv.lock +bridge/node_modules/ +bridge/package-lock.json # IDE / Tools .vscode/ @@ -31,8 +33,10 @@ uv.lock workspace/ skills/ memory/ +media/ .deno_cache/ *.ipynb *CLAUDE.md *AGENTS.md -*meals/ \ No newline at end of file +*meals/ +botpy.log diff --git a/EvoScientist/channels/README.md b/EvoScientist/channels/README.md new file mode 100644 index 0000000..c445bb9 --- /dev/null +++ b/EvoScientist/channels/README.md @@ -0,0 +1,552 @@ +# Channels + +EvoScientist provides unified integration with 11 messaging platforms.
