Code Block Studio 1.3.3 — preview

Code Block Studio makes fenced code blocks easier to read, copy and format in Joplin Desktop. Highlighting, fonts and formatters are bundled and run locally.

This is the first public GitHub preview. Version 1.3.3 keeps formatting feedback visible in the sticky toolbar on long code blocks. It also includes optional Ko-fi support links and an MIT licence naming Leonard Powers, alongside the bundled dependency notices.

Install

Download local.lpowers.code-studio.jpl below. In Joplin Desktop, open Tools → Options → Plugins, choose the gear menu → Install from file, select the installer, and restart Joplin. Existing installations retain the plugin ID and preferences.

Validation and limits

A fresh source checkout passed dependency installation, TypeScript checks, the build and all 52 tests. The dependency check reports zero known vulnerabilities. The installer was built from the clean source commit shown in its metadata; SHA256SUMS covers the installer, metadata and source archive.

This is a preview, pending final live acceptance in Joplin. The declared minimum Joplin 3.3 has not been verified; earlier live checks used 3.7.22 on Linux. Windows and macOS remain untested, and mobile is not supported. Browser Rich Text tests use a TinyMCE stub. Use disposable notes for acceptance checks.

The plugin has not been published to npm or the Joplin catalogue.

Optional support: Ko-fi.
