Extending Editora with plugins
Editora just gained a plugin system, and it’s built on the same idea that runs the rest of the editor: everything is a command. A plugin doesn’t get a special back door, it registers the same kind of commands, keybindings, and tool windows the core uses. That keeps the API small and the editor consistent.
Two ways to write one
A plugin is a folder with a plugin.json manifest. From there you can go as
light or as deep as you like.
Declarative plugins need no code at all. The manifest can register commands
that run a shell command, bind keys, and point at snippets/ and templates/
folders to merge into the built-in sets. That’s enough for a surprising amount:
a formatter, a task runner, a code generator.
Java plugins implement the Plugin interface against the exported
com.editora.plugin API and get a PluginContext:
public class HelloPlugin implements Plugin {
public void start(PluginContext ctx) {
ctx.registerCommand("hello", "Say Hello", () ->
ctx.setStatus("Hello from a plugin!"));
ctx.bindKey("C-c C-h", "hello");
}
}The context lets you register tool windows, add editor right-click items and
status-bar segments, and reach the active editor through a narrow facade
(text(), selectedText(), replaceSelection(), setText(), …), never the
internals.
Plugin registry
Plugins install from a curated registry
adriandeleon/editora-plugins
that ships 19 plugins today: text transforms, encoders, hashers, a regex
tester, a scratchpad, a calculator, a color picker, “Open on GitHub,” and more.
Editora fetches the index over HTTPS, verifies each download’s sha-256, and
unpacks it with a zip-slip-hardened extractor. You can also install a .zip
straight from disk.
Plugin Security
Plugins are not sandboxed! a Java plugin runs with the same access as the editor. That’s deliberate (it’s what makes them powerful), but it means you should only install plugins you trust, the same way you would a VS Code or IntelliJ extension. Plugins are off by default; you opt in per plugin.
Browse what’s available on the Plugins page, or read the docs and ship your own. I’d love to see what you build! Discussions is open.
