lookatme.contrib.render

This is a lookatme extension that renders code blocks of supported languages into images, which are then rendered using whichever image rendering options the user has available.

To get something useful out of this extension, you must have an image-rendering contrib extension installed for lookatme that is able to display images, such as lookatme.contrib.urwid_ueberzug. See lookatme's list of known extensions for other potential options.

Example

After installing this lookatme, this extension, and lookatme.contrib.urwid_ueberzug, you should be able to see something like this:

Installation

pip install lookatme.contrib.render

The following languages are currently supported:

Code-block Language(s)	Renderer	Executable Required	Note
dot, graphviz	Graphviz	dot	apt-get install graphviz
mermaid	mermaid.cli	mmdc	npm install mermaid.cli; export PATH="$PATH:$(pwd)/node_modules/.bin"

The height of the rendered image can be set by either appending -N or N to the codeblock language to specify the number of rows the rendered image should use when being displayed.

The example below will render a mermaid-js graph with a height of 10 rows:

```mermaid-10
graph TD
  A0 -> B
  A1 -> B
  B -> C
  C -> D
```
