rustdoc json output on stdout ?

[gl-yziquel]

Hi.

As of today, it seems that there is no out of the box way to get rustdoc json output on stdout. I see no way to augment the rustdoc src/lib.rs -Zunstable-options --output-format json invocation to handle output on stdout.

This is a shame as I'd like to perform rustdoc -> some jq or better for preprocessing -> tera templating -> makeinfo for texinfo generation, all of that through pipes.

As of today, the only piece of code that doesn't support piping in the above is rustdoc.

Being kind of a dinosaur, I like to get things done the old unixish way, with one tool doing something and only that, and having pipe support would allow to generate my texinfo manual from rustdoc json output without having to go jumping through hoops using temporary files.
