AST Inspector

Hi, everyone!

When I was exploring AST in Pharo, at the beginning it seemed a bit
confusing for me how the tree looks like, or which part of code some node
represents etc. As I'm working with ASTs for a while now, still not an
expert ;), I decided to make a simple AST Inspector for myself and everyone
that needs it. Hopefully, this inspector will make peoples lives easier when
learning ASTs. For now its very raw. Inspector shows the code and its AST
representation visually like in the picture.
Also you can select/deselect a nodes of AST an see which part of code it
represents (like in the picture above). Functionality ends here :) What do
you think about it? Maybe you guys have some cool ideas for this inspector?

Need a bit of anti-aliasing for the round shapes :)

Right :)

 

I wonder how it will look with a long method: they usually have rather flat ASTs that would result in a wide diagram.

Yes it will be pretty huge. However, 1) there is an option to scale the tree (nodes) 2) most of the methods should not be very long ;)
Still the problem remains.

I built it rather for fun and my possible future work, than for wide usage. But I think it may be nice for some people to one-click and see the tree, and play with it.

About GT inspector: yes I've seen the ast view in inspecotr, and it's amazing how many things we can do with it.

What is it drawn with?

If you already seen the GT view, perhaps this means that you were missing something. Is it only the visual representation, or do you miss something else?

For the most part the missing part is the visual representation of the tree. However I did this little inspector because in the future I (maybe) will implement a tool for code rewriting like Rewrite Tool, but only the rule creation process will be done by manipulating visual representation of the ASTs.

 

Also, you can embed your view directly in GT.

That's cool and I know - seen it at Pharo Days :)
