Creating New Abbreviations about docstringextensions.jl HOT 2 OPEN

I have an update on this that seems to be working but is also pretty hacky. I realized that the problem I was having was that the docstring for my type occurred before the data necessary for the abbreviation was available. In other words the following example wouldn't be able to grab info from get_doc (what I'm doing is a lot more complex but this is the closest to a MWE I could get).

"""
MyType
$(MYABBREVIATION)
"""
struct MyType end

get_doc(::MyType) = "some documentation")

What I do later is similar to

d = @doc MyType
first(d.meta[:results]).object = nothing

I think the reason this works is because when parsedoc is called it doesn't actually parse the docstring unless docstring.object === nothing. So this forces it to parse the docstring again.

This seems like a pretty unsafe solution though and it would be cool if there was a way to work around this safely.

We don't have any publicly defined API for this purpose, but if you or someone else would like to take a stab at designing and implementing it, I think it would be a good addition to the package.

This is correct -- the parsed docstring gets cached. However, the caching only happens when you try do look up the docstring, e.g. in the REPL. So if your custom abbreviation is registered before that happens, like during the parsing of your package/module, it should work.
