My Example PlantUML

Overview

This is my take on a fine example created by @jerieljan. To see their explanation, check out How I Do PlantUML.

Usage

Take a look at the comments of the Example.puml file. Based on those comments and the explanation from the aformentioned Gist, you should be able to put a small example together.

PlantUML with Style -- How I do PlantUML

I use PlantUML a lot. It's what I use for drawing all sorts of diagrams and it's handy because of its easy markup (once you get used to it) while making things easy to maintain as projects grow (thanks to version control)

This gist explains how I do my PlantUML workspace in a project.

  • The idea is to keep a globals directory for all diagrams to follow (like the "stylesheet" below) to keep things consistent.
  • I use a stylesheet.iuml file that keeps the use of colors consistent through use of basic FOREGROUND, BACKGROUND and ACCENT colors.
  • The style-presets.iuml file defines these colors so you can make "presets" or "themes" out of them.
  • As stated in the stylesheet.iuml, you'll need the Roboto Condensed and Inconsolata fonts for these to work properly.
  • You can choose to either run the PlantUML jar over your file/s, or use an IDE like VSCode with the PlantUML extension. Here's a preview of example-sequence.puml for example: https://imgur.com/Klk3w2F

Some more info can be found here https://help.ubuntu.com/community/ServerGUI. I assume you start with a clean install of Ubuntu Server 16.04 (some modifications may be needed for older versions of Ubuntu). Depending on your needs you can do these:
Minimal GUI:
sudo apt install xorg
sudo apt install --no-install-recommends openbox
Run the command startx and openbox will start (you can open a terminal there and run any application you want)
