GNU libreadline, and the libedit-based library shipped on stock OS-X
python, require different key-binding syntaxes to enable tab completion.
The previous commit to fix this (0977ef0) added both binding commands
Unfortunately when GNU libreadline is given the libedit-style
command (i.e. "bind ^I rl_complete"), it binds the letter "b" to a
non-existent command "ind", or something, and as a result the letter "b"
doesn't work anymore.
This patch uses the readline docstring to sense which flavor is
installed, and only runs the one binding command that's appropriate.
refs #37
Apple's stock python doesn't use GNU libreadline, instead it uses BSD
libedit with a readline compatibility interface. The syntax to enable
tab completion is different for libedit. By including both bindings,
autocomplete should work on both flavors.
Closes#37. Thanks to @wsanchez for the catch and the fix.
'readline' is part of the python stdlib, so declaring a dependency on it
doesn't help. It doesn't exist on windows, and the pypi 'readline'
module doesn't work on windows. So instead, just attempt to import
readline, and if that fails, fall back to a non-completion flavor.
* use modern/portable "next(iter)" instead of "iter.next()"
* use six.moves.input() instead of raw_input()
* tell requests' Response.iter_lines that we want str, not bytes
This fixes the situation where you start the receiver first, then start
the sender, then you hit TAB on the receiver.
This somewhat improves the situation where you start the receiver first,
hit TAB (getting nothing), then start the sender, then hit TAB on the
receiver again. The second TAB will list the channel-ids, but won't
insert the only one as it's supposed to. You must type something (which
you can erase) and then hit TAB again to get a unique channel-id
inserted. But at least you can tell which one to type.
The first TAB runs the completer with readline.get_completion_type()
equal to 9=TAB=try-to-insert. The second (and subsequent) TABs use
63=?=list-matches, and it won't go back to 9 until you type something.
