BITOP example broken about redis-io

Ping? This is still broken :)

Same thing for INFO:

Looks like INFO needs a custom handler. This fixes INFO on my local machine:

diff --git a/lib/interactive/namespace.rb b/lib/interactive/namespace.rb
index 05f4990..fd8ace7 100644
--- a/lib/interactive/namespace.rb
+++ b/lib/interactive/namespace.rb

         # Destination key
         if args.size >= 1

What's strange is that SCAN and COMMAND INFO have no custom handler either but... they just work.

[mattsta]

So, delving deeper into figuring out how all this works...

SCAN actually has no in-page console output—everything there is just pre-formatted output. But, the pre-formatted output looks like the live in-page console. It's misleading. So, there's no bad behavior with in-page SCAN.

Now, COMMAND INFO is special because the namespace.rb/pattern() parser is busted. It does args.shift which takes the first word of the entire in-page command string. So, the parser thinks the entire command COMMAND INFO get set eval is just COMMAND with arguments of ["INFO", "get", "set", "eval"].

So, technically, COMMAND INFO should be broken without a custom handler, but it still works.

Mystery 1 solved! We do need the custom case handler for INFO, but everything else is either working as designed or broken and still working as intended.

Mystery 2: Why doesn't BITOP work properly in the web console? BITOP was missing from the custom handler, and it uses three key positions that needed to be registered for namespacing. Console BITOP support can be enabled with:

diff --git a/lib/interactive/namespace.rb b/lib/interactive/namespace.rb
index 05f4990..b8dd8d3 100644

Mystery 2 solved!
