#+title:Grasp (deprecated in favour of [[https://github.com/epost/purescript-grasp][purescript-grasp]])

Grasp, short for GRAph Specification Processor, allows you to:

- Specify graphs in a super concise format.

- Output graph structure as JSON.

- Leave formatting (layout, colouring, etc.) to other tools, such as GraphViz.

* Examples

Syntax is inspired by both GraphViz and CYPHER:

#+BEGIN_EXAMPLE

# concise node and edge syntax

a -> b

b -> c; c -> d

d, e, f -> g

# labeled edges

1 -succ-> 2

# type annotations

x:A -f-> y:B

y -g:G-> z

#+END_EXAMPLE

* Features

- [X] no formatting, only structure

- [X] comma syntax: ~a,b,c -> d, e~

- [X] type syntax? ~a:A - b:B -> c:C~

- [X] comments

- [ ] transitive syntax? ~a -> b -> c -> d~

- [ ] allow (back)slash in node / edge labels? (handy for paths and URLs)?

- [ ] quoted node / edge labels?

- [ ] dash as part of identifiers maar dan zonder conflicts or ambiguities

- [ ] question mark as part of identifiers

- [ ] node / edge ids? maybe using hash mark?

- [ ] allow references: graph transformations, styling, comments, legend, etc

- [ ] support formats other than JSON.
