Extension summary

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).

Pros
  • Very useful. I like that it refreshes when I save updates to the file in my text editor.

  • The diagram viewer recently stopped working on multiple machines.
