diaryx_publish_extism

Extism guest plugin wrapping publish/export functionality for browser and native runtimes. The publish pipeline now comes from diaryx_core::publish; there is no separate diaryx_publish crate dependency anymore.

Overview

This crate builds to a .wasm plugin loaded by:

• Native via diaryx_extism (wasmtime)
• Web via @extism/extism

The plugin handles:

• export command dispatch (PlanExport, ExportToMemory, etc.)
• converter lifecycle (DownloadConverter, IsConverterAvailable)
• format conversion (ConvertFormat, ConvertToPdf) by running converter WASI modules through host_run_wasi_module

Exports

Build

This repository can be built standalone with Cargo:

cargo build --target wasm32-unknown-unknown -p diaryx_publish_extism --release

When vendored into the Diaryx monorepo, you can still use the monorepo helper:

cd ../diaryx && ./scripts/build-wasm.sh

which copies the artifact to apps/web/public/plugins/diaryx_publish.wasm.
