pandoc-plantuml-filter

Pandoc filter which converts PlantUML code blocks to PlantUML images.

```plantuml
Alice -> Bob: Authentication Request
Bob --> Alice: Authentication Response

Alice -> Bob: Another authentication Request
Alice <-- Bob: another authentication Response
```

Usage

Install it with pip:

pip install pandoc-plantuml-filter

And use it like any other pandoc filter:

pandoc tests/sample.md -o sample.pdf --filter pandoc-plantuml

The PlantUML binary must be in your $PATH or can be set with the PLANTUML_BIN environment variable.

Additional parameters

You could pass additional parameters into plantuml filter which will be processed as picture's options:

```{ .plantuml height=50% plantuml-filename=test.png }
Alice -> Bob: Authentication Request
Bob --> Alice: Authentication Response
```

The plantuml-filename parameter create a symlink for the destination picture, which could be used in the same file as an image directly.

Control the output file-type

The generated file-type can be controlled via the file metadata:

---
plantuml-format: svg
---

Or directly via the cli --metadata argument.

pandoc tests/sample.md -o sample.pdf --filter pandoc-plantuml --metadata=plantuml-format=svg

But there is ...

There are a few other filters trying to convert PlantUML code blocks however they all failed for me.
