Visualizing a Julia AST (abstract syntax tree) as a tree

[David P. Sanders]

Hi,

In case it's useful for anybody, the following notebook shows how to use the LightGraphs and TikzGraphs packages

to visualize a Julia abstract syntax tree (Expression object) as an actual tree:

Currently it requires the master branch of TikzGraphs.jl.

It would be great to have some kind of Julia snippet repository for this kind of thing that is less than a package but

provides some kind of useful functionality. 

David.

Here's an example of the output.

Hi David this is very cool and useful!  I'd be happy to have it in PlotRecipes if you don't find a better home for it.  If there's a generic function to produce an adjacency list then we could use my graph recipes.  When I have the time (i.e. soonish when I really want nicer graphs) I plan on incorporating the new GraphLayout into the recipes.  Let me know.

Hi Tom,

That sounds like a pretty good idea, though I have to say I haven't grokked PlotRecipes yet.

Since LightGraphs.jl doesn't support labelled graphs, maybe 

https://github.com/JuliaGraphs/Networks.jl

is the right solution? Do you have any suggestions about this?
