Crate streamdown_plugin 

Streamdown Plugin System

This crate provides the plugin architecture for extending streamdown with custom content processors. Plugins can intercept lines of input and transform them before normal markdown processing.

Plugin Behavior

• If a plugin returns None, it’s not interested in the line
• If a plugin returns Some(ProcessResult::Lines(vec)), those lines are emitted
• If a plugin returns Some(ProcessResult::Continue), it’s buffering input
• A plugin that returns non-None gets priority until it returns None

Example

use streamdown_plugin::{Plugin, ProcessResult, PluginManager};
use streamdown_core::state::ParseState;
use streamdown_config::ComputedStyle;

struct EchoPlugin;

impl Plugin for EchoPlugin {
    fn name(&self) -> &str { "echo" }

    fn process_line(
        &mut self,
        line: &str,
        _state: &ParseState,
        _style: &ComputedStyle,
    ) -> Option<ProcessResult> {
        if line.starts_with("!echo ") {
            Some(ProcessResult::Lines(vec![line[6..].to_string()]))
        } else {
            None
        }
    }

    fn flush(&mut self) -> Option<Vec<String>> { None }
    fn reset(&mut self) {}
}
