Heh. Everything is printed structurally (all the way down) because we don't see the typedefs for, eg, Infotable and DataTableThing as visible aliases.

So, two remarks:

1. We aughta use those aliases. I'll look into why we aren't and fix it.
2. Matt Bierner (@mjbvz) Does vscode want a hard max on how much text we send back for quickinfo? Should the result be truncated?

[mjbvz]

I think we can set a reasonable upper bound on this. Perhaps something like 2000 characters? Even that is probably overkill

[weswigham]

Would you like some kind of text at the truncation location (eg, ...), or just a hard cut?

[mjbvz]

A ... would probably be better. That way users know some information is not shwon

We could do this truncation on the VS Code side too but it's probably best avoid sending the data from the ts server in the first place

[weswigham]

Much. The buffer encoding takes a fair chunk of time; usually at least 50% as long as actually generating the string did.
