Crate meta_plugin_protocol 

Shared plugin protocol types for meta subprocess plugins.

This crate defines the communication protocol between the meta CLI host and its subprocess plugins (meta-git, meta-project, meta-rust, etc.).

The protocol works as follows:

1. Host discovers plugins via --meta-plugin-info (plugin responds with PluginInfo JSON)
2. Host invokes plugins via --meta-plugin-exec (sends PluginRequest JSON on stdin)
3. Plugin responds with either a PlanResponse JSON (commands to execute) or direct output

Structs

ExecutionPlan

An execution plan returned by a plugin, containing commands for the host to execute.

PlanResponse

Wrapper for the execution plan response (the JSON envelope plugins emit).

PlannedCommand

A single command to be executed by the host via loop_lib.

PluginDefinition

Definition of a plugin, used by run_plugin() to eliminate main.rs boilerplate.

PluginHelp

Help information for a plugin’s commands.

PluginInfo

Metadata about a plugin, returned in response to --meta-plugin-info.

PluginRequest

A request from the meta CLI host to a plugin, sent as JSON on stdin.

PluginRequestOptions

Options passed from the host to the plugin as part of the request.

Enums

CommandResult

The result of a plugin command execution.

Functions

output_execution_plan

Serialize and print an execution plan to stdout.

output_execution_plan_full

Serialize and print a full execution plan with pre/post commands to stdout.

read_request_from_stdin

Read and parse a PluginRequest from stdin.

run_plugin

Run a plugin’s main loop. Handles --meta-plugin-info and --meta-plugin-exec flags.
