This is a vim syntax file for PlantUML.

The filetype will be set to plantuml for *.pu, *.uml or *.plantuml files or if the first line of a file contains @startuml.

Additionally the makeprg is set to plantuml assuming you have this executable in your path. The plantuml file could contain something like

#!/bin/bash
java -jar $HOME/lib/java/plantuml.jar -tsvg $@

You can change the name of this file by setting g:plantuml_executable_script

Copy these files into the .vim subdirectory of your home directory. That is, ~/.vim

Clone the repository to your machine somewhere. In this example, to your home directory. Then copy the files.

cd ~
git clone https://github.com/aklt/plantuml-syntax.git
cp -r ~/plantuml-syntax ~/.vim

On the Microsoft Windows operating system you will use slightly different commands.
