* Skeleton implementation Lots and lots of TODOs * Bootstrap simple CustomValue plugin support test * Create nu_plugin_custom_value * Skeleton for nu_plugin_custom_values * Return a custom value from plugin * Encode CustomValues from plugin calls as PluginResponse::PluginData * Add new PluginCall variant CollapseCustomValue * Handle CollapseCustomValue plugin calls * Add CallInput::Data variant to CallInfo inputs * Handle CallInfo with CallInput::Data plugin calls * Send CallInput::Data if Value is PluginCustomValue from plugin calls * Remove unnecessary boxing of plugins CallInfo * Add fields needed to collapse PluginCustomValue to it * Document PluginCustomValue and its purpose * Impl collapsing using plugin calls in PluginCustomValue::to_base_value * Implement proper typetag based deserialization for CoolCustomValue * Test demonstrating that passing back a custom value to plugin works * Added a failing test for describing plugin CustomValues * Support describe for PluginCustomValues - Add name to PluginResponse::PluginData - Also turn it into a struct for clarity - Add name to PluginCustomValue - Return name field from PluginCustomValue * Demonstrate that plugins can create and handle multiple CustomValues * Add bincode to nu-plugin dependencies This is for demonstration purposes, any schemaless binary seralization format will work. I picked bincode since it's the most popular for Rust but there are defintely better options out there for this usecase * serde_json::Value -> Vec<u8> * Update capnp schema for new CallInfo.input field * Move call_input capnp serialization and deserialization into new file * Deserialize Value's span from Value itself instead of passing call.head I am not sure if this was correct and I am breaking it or if it was a bug, I don't fully understand how nu creates and uses Spans. What should reuse spans and what should recreate new ones? But yeah it felt weird that the Value's Span was being ignored since in the json serializer just uses the Value's Span * Add call_info value round trip test * Add capnp CallInput::Data serialization and deserialization support * Add CallInfo::CollapseCustomValue to capnp schema * Add capnp PluginCall::CollapseCustomValue serialization and deserialization support * Add PluginResponse::PluginData to capnp schema * Add capnp PluginResponse::PluginData serialization and deserialization support * Switch plugins::custom_values tests to capnp Both json and capnp would work now! Sadly I can't choose both at the same time :( * Add missing JsonSerializer round trip tests * Handle plugin returning PluginData as a response to CollapseCustomValue * Refactor plugin calling into a reusable function Many less levels of indentation now! * Export PluginData from nu_plugin So plugins can create their very own serve_plugin with whatever CustomValue behavior they may desire * Error if CustomValue cannot be handled by Plugin |
