commit 48e955db099c5295edcee19508844fbd812b5948 Author: Damian Johnson atagar@torproject.org Date: Mon Sep 19 08:10:12 2011 -0700
fix: tab completion could truncated results
When the tab completion matches had prefixes with multiple cases (for instance "MAPADDRESS" and "MapAddress") then tab completion would crop input to the common portion (just "M"). Instead picking the prefix with the largest set of results. This isn't perfect since it could hide some results but seems like the best option for getting around this stupid behavior. --- src/util/torInterpretor.py | 24 ++++++++++++++++++++++++ 1 files changed, 24 insertions(+), 0 deletions(-)
