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(-) diff --git a/src/util/torInterpretor.py b/src/util/torInterpretor.py index d5abb88..593f29c 100644 --- a/src/util/torInterpretor.py +++ b/src/util/torInterpretor.py @@ -348,6 +348,30 @@ class TorControlCompleter: if text != self._prefix: self._prefix = text self._prefixMatches = self.getMatches(text) + + # Tab completion fills in the first common prefix which can be + # problematic if they don't all match.
