[plantuml] Fix config to have the package use local jar execution

If not done plantuml-mode will try to work with the online
server and fail during parsing of its response.

Description

This layer enables support for plantuml-mode, which provides a major-mode for plantuml. PlantUML is a tool to generate UML diagrams from plain-text.

For help with how to use plantuml, see the plantuml website and the reference guide.

The official file extension supported by this layer is .pum. If you want something else, set it in your user-config function of your ~/.spacemacs file.

For example, the following diagram can be defined as follows:

  @startuml
  JAremko->robbyoconnor : I think the docs can benefit from some kind of illustration
  JAremko<-robbyoconnor : I'm too lazy -- I have actual work to do. I link to the docs. If you can write me a diagram in plantuml, I'll gladly compile and add it.
  JAremko->robbyoconnor : *gives ths diagram*
  robbyoconnor<-JAremko : *robbyoconnor adds it and JAremko is happy*
  ...
  robbyoconnor->theOtherPerson : And they thinks it's funny? Yup, they definitely finds it funny. Right?

Features:

Syntax highlighting
Diagram preview in various output formats
Embedding into org documents
Controlling the Plantuml compiler directly from emacs

Install

To use this contribution add it to your ~/.spacemacs

  (setq-default dotspacemacs-configuration-layers '(plantuml))

To control the Plantuml compiler you also need to download the Plantuml jar and configure the plantuml-jar-path respectively:

  (setq-default dotspacemacs-configuration-layers '((plantuml :variables plantuml-jar-path "~/plantUml.jar")))

To get the full range of Plantuml compilations working, you will also need the native package graphviz installed on your system.

If you don't want to compile locally you can set plantuml-exec-mode to server. This will make plantuml try to use an online compile server. Be warned these resources change often and plantuml-mode is not always up-to-date. For a stable user experience we recommend using the default jar option instead.

  (setq-default dotspacemacs-configuration-layers '((plantuml :variables plantuml-default-exec-mode 'server)))

Org-Babel Integration

To enable the execution of embedded plantuml code blocks within Org-Mode documents, define a value for org-plantuml-jar-path in your ~/.spacemacs:

  (setq-default dotspacemacs-configuration-layers '((plantuml :variables plantuml-jar-path "~/plantUml.jar" org-plantuml-jar-path "~/plantUml.jar")))

Key bindings

Key binding	Description
`SPC m c c` or `C-c C-c`	Build diagram from the text in the current buffer
`SPC m c o`	Set the output type (`unicode text`, `svg`, or `png`)
