Pandoc-mm

Generate a mindmap from an org-mode file. Complete with annotations.

Foreword

This is just a tiny wrapper built on the shoulders of a giant.

Example

from this:

#+TITLE: Category Theory

#+COLUMNS: %20ITEM %10color %10placement

:END:       

A triple $\mathcal{C}(O, M, \bullet)$ where 

- $\forall o \in O, \exists id_o \in M$
- $\bullet$ is defined for all connected objects 
- $\bullet(A \rightarrow B, B \rightarrow C) = A \rightarrow C$
- $(f \bullet g) \bullet h == f \bullet (h \bullet g)$ 
- $id_x \bullet f = f \bullet id_y$

** Monoid

*** Free Monoid 
:PROPERTIES:
:END:

A free monoid of M is just a monoid $\mathcal{M}(List[M], [], ++)$. 

*** Free Monoid 
:PROPERTIES:
:placement: 15, -5
:END:

A free monoid of M is just a monoid $\mathcal{M}(List[M], [], ++)$. 

*** Action 
:PROPERTIES:
:END:

An action of a $\mathcal{M}(M, id_0, \star)$ over a set $S$ of states is a
function \[ M \times S \rightarrow S \]

It is equivalent to an automata

Installation

I'd strongly suggest to install it through Stack:

git clone https://github.com/vzaccaria/pandoc-mm.git
cd pandoc-mm 
stack install .

This should compile the binary and put it into something reachable in your path. In my case this is ~/.local/bin.

Usage

    pandoc-mm FILE [ -x ]
    pandoc-mm --help | -h
    pandoc-mm --version

Options:
    -x, --latex            Output raw latex
    -h, --help             Show help
    --version              Show version.

Arguments
    FILE                   Org file containing the mindmap

Without the -x option, it generates a pdf with xelatex and pdfcrop. Otherwise, it generates standalone latex you can compile with your own toolchain.

Supported syntax

:PROPERTIES: can be the following:

• :color: is any color in a syntax understandable by Tikz.

• :placement: absolute coordinates of the annotation. If not present, i) it is assumed to be placed below the previous annotation or ii) if it is the first annotation then it is assumed to be current page.south east. Use property HELPLINES (see commented text in the example above) to show a help grid in the pdf.

Warning: it turns out that the official org-mode grammar does not accept spaces between properties, or between properties and headings. These are thus invalid headings:

* Category

:PROPERTIES:
:color: blue!30
:END:       

or:

* Category
:PROPERTIES:
:color: blue!30

:END:
