Bidirectional userscripts / output from commands

[The-Compiler]

In several situations (mainly userscripts and in the future plugins), it would be nice if qutebrowser commands could have a return value, which then gets communicated back to the caller in some way.

Here is a "simpler" solution which I hope fulfills a large number of use cases. I understand though it is probably better to do a proper solution which is what this issue is about. Idea: re-execute the userscript with the output as a last argument. This would make it easy for existing bash scripts to use this functionality. Would work on windows. Probably need a way to specify arguments to the script (so it knows its getting output).

For example I really want to have password_fill interact with qutebrowser to give a list of passwords to fill. Right now it has support for dmenu which isn't on mac. It would be cool if it could get qutebrowser to do what dmenu does.

We could serialize the return values from jseval as JSON and just have a QUTE_FIFO_OUT or QUTE_EVALUATED file to wait for newlines from. It doesn't have to be complicated.

Things are always simple if you're not actually implementing and maintaining them 😉 A solution for this will at least need to be designed to work with more commands than only jseval, even if initially only a subset could be supported.
