PlantUML Viewer Extension

# PlantUML

Renders UML diagram as defined in a text file. For full syntax of the text file, see:
http://plantuml.sourceforge.net/index.html

1. Install the extension from Chrome Web Store.
2. Open text file from web server with UML diagram definition in browser (the text starts with @startuml).
3. See the rendered UML diagram!

Chrome does not allow fetching content from local files anymore, so you have to start a local web server that will serve the local text file. One simple way if you have Python 3 is to run `python -m http.server` command in the directory with your PlantUML files.

## Features

- Automatically updates the diagram when the file at given URL is changed.
- You can use your own server by changing the server URL in the popup of the action button (action button is displayed while viewing PlantUML files).

## Permissions

Your data on all websites
:\tUsed to check whether the current page contains PlantUML diagram.

## History
