Tree pretty printer

[Martin Clausen]

I am considering submitting a tree structure pretty printer, would that be welcome?

It would print tree structures similar to this: https://gist.github.com/maacl/b0795e5f3d4ab72ca8add1e2d091e0e4#file-output-txt

I imagine it would take a dispatch function and a value for branches and one for leaves and perhaps an optional map of symbols to use for the construction of the tree.

Cheers,

Martin

Hi Martin,

I don't think we'll add something like this, but seems like a useful library.

Alex,

Thanks for the quick and clear feedback. For my (and perhaps that of others) edification would you share your thinking on why not? 

My thinking was that such a function would seem quite parallel to the print-table function already included in clojure.pprint.

Cheers,

Martin

Well first, my default answer for adding stuff to core is no, and I don't think the frequency of need for this changes that. Secondly, I think text trees are pretty unwieldy (whereas text tables are more commonly useful) and generally UIs that support folding functionality tend to be better (and that actually exists in clojure.inspector already). And finally, I think there are probably a lot of options you might to configure such a tree and all that just seems to suggest putting it in an external library instead.
