# Deprecation notice
|
|
|
|
After [the decision to merge](https://github.com/zwz/plantuml-mode/issues/8) together `puml-mode` and `plantuml-mode`, this branch and the code herein have been deprecated and are here for historical reasons only. Please migrate to [skuro/plantuml-mode](https://github.com/skuro/plantuml-mode).

|
A [PlantUML](http://plantuml.sourceforge.net/) major mode for Emacs.
|
|
|
|
# Installation
|
|
|
|
Make sure you have [MELPA](http://melpa.org/) enabled in your ``emacs.d``. Then, you can just
|
|
|
|
M-x package-install<RET>
|
|
puml-mode<RET>
|
|
|
|
Also, to enable preview you need to tell `puml-mode` where to locate the PlantUML JAR file. By default it will look for it in `~/plantuml.jar`, but you can specify any location with:
|
|
|
|
M-x customize-variable<RET>
|
|
puml-plantuml-jar-path<RET>
|
|
|
|
# Features
|
|
|
|
- Syntax highlight
|
|
- Autocompletion
|
|
- Preview
|
|
|
|
# Enable the major mode
|
|
|
|
You can automatically enable `puml-mode` for files with extension `.puml` or `plantuml` by adding the following to your `.emacsrc`:
|
|
|
|
;; Enable puml-mode for PlantUML files
|
|
(add-to-list 'auto-mode-alist '("\\.puml\\'" . puml-mode))
|
|
(add-to-list 'auto-mode-alist '("\\.plantuml\\'" . puml-mode))
|
|
|
|
Of course, you can always enable manually the major mode by typing `M-x puml-mode` once in the desired PlantUML file buffer.
|
|
|
|
# Usage
|
|
|
|
You can tell `puml-mode` to autocomplete the word before the cursor by typing `M-x puml-complete-symbol`. This will open a popup with all the available completions as found in the list of keywords given by running PlantUML with the `-language` flag.
|
|
|
|
To render the PlantUML diagram within Emacs, you can hit `M-x puml-preview`. This will run PlantUML and display the result in the `*PUML-Preview*` buffer. The format used to render the diagram is automagically chosen from what's supported by your Emacs. It will be one of the following, in order of preference:
|
|
|
|
- SVG
|
|
- PNG
|
|
- Unicode ASCII art
|
|
|
|
## Default key bindings
|
|
|
|
The following shortcuts are enabled by default:
|
|
|
|
C-c C-c puml-preview: renders a PlantUML diagram from the current buffer in the best supported format
|
|
|
|
C-u C-c C-c puml-preview in other window
|
|
|
|
C-u C-u C-c C-c puml-preview in other frame
|
|
|
|
## Integration with `org-mode`
|
|
|
|
You can use `puml-mode` to edit PlantUML source snippets within an [`org-mode`](http://orgmode.org/) document. To do so, you need to first register it with the `plantuml` language:
|
|
|
|
```
|
|
(add-to-list
|
|
'org-src-lang-modes '("plantuml" . puml))
|
|
```
|
|
|
|
Then you can edit a `plantuml` code block with `puml-mode` by hitting `C-'` while inside of the code block itself:
|
|
|
|
```elisp
|
|
#+BEGIN_SRC plantuml
|
|
<hit C-' here to open a puml-mode buffer>
|
|
#+END_SRC
|
|
```
|
|
|
|
When in the `puml-mode` buffer you can then hit again `C-'` to return to the original `org-mode` document.
|
|
|
|
# Troubleshooting
|
|
|
|
As of `v0.6.2` the following commands have been added to help resolving problems:
|
|
|
|
```
|
|
puml-enable-debug
|
|
puml-disable-debug
|
|
```
|
|
|
|
With debug enabled, the actual command used to invoke PlantUML is printed into a buffer called `*PUML Messages*`. You can inspect that buffer to make sure that PlantUML is properly set up, or use it to supply extra information when opening [issues](https://github.com/skuro/puml-mode/issues).

# Credits
|
|
|
|
This project stemmed from the great work of [Zhang Weize](http://zhangweize.wordpress.com/2010/09/20/update-plantuml-mode/),
|
|
and the current code still borrows a lot from it.
|
|
|
|
Thanks to [Pavel G. Koukoushkin](https://github.com/svargellin) for implementing the preview functionality.
