Is it possible to search the julia registry for a function

General Usage
1

Is there a tool that will search the packages in the Julia registry for a function name?

I sometimes come across online examples that use a Julia function I would also like to use but can’t find the package that contains the function because the code snippet elided the using statements.

In my experience the “symbol search” is buggy, so I usually use the code search instead. Bug reports:

Thanks for the tip. I tried code search but it doesn’t have a “definition” search. In the AbstractIrrational code search returns 217 results which is a lot to look through to find the defining package.

Is there a way to get just the source files that define the symbol using code search?

AbstractIrrational is defined in Base, which you can discover with

julia> parentmodule(AbstractIrrational)
Base

Filtering all source files in a registry with a symbol is going to give a lot of results too. Filtering further to definitions using a symbol needs the Julia runtime because plain text search can’t distinguish imports, multi-line strings, metaprogramming, and variant syntax. Just a headache when people don’t share project files.
