commit b02b595cda76428723e000082089cc0270d47298 Author: Damian Johnson atagar@torproject.org Date: Sun Oct 25 13:46:21 2015 -0700
Use methods for ConfigEntry attributes rather than a single get()
To get all attributes we had a single ConfigEntry get() method that took an enum. This was done to avoid needing a separate sort_value() method. Fine idea, but clunky.
Our connection panel has a sort_value(), that's fine. Also we'll be moving much of this to Stem, in which case proper methods jive better. --- nyx/config/attributes.cfg | 16 ++-- nyx/config_panel.py | 190 +++++++++++++++++++++++++++------------------ nyx/connection_panel.py | 5 +- 3 files changed, 122 insertions(+), 89 deletions(-)
