[arm/master] Adding back the color prompt, with padded prompt
by atagar＠torproject.org 13 Sep '11

commit 0fb7dd674c9969d55c21fca9040f7f7bcfd09950 Author: Damian Johnson <atagar(a)torproject.org> Date: Tue Sep 13 08:58:29 2011 -0700 Adding back the color prompt, with padded prompt This is a hack to maintain a color prompt while sidestepping the 'http://bugs.python.org/issue12972' bug in *most* use cases. This pads the prompt so the original issue doesn't manifest unless the user's input exceeds around sixty characters or so. However, it introduces a new bug where tiny terminals (smaller than the padded width) get screwed up. This obviously isn't a great situation and it could be argued that a colored prompt isn't worth these issues. However, the problem use cases strike me as being fairly rare (and I much prefer the green and bolded '>>>') so going with this for now. Patches welcome if someone has a better solution. --- src/util/torInterpretor.py | 13 +++++++++++-- 1 files changed, 11 insertions(+), 2 deletions(-) diff --git a/src/util/torInterpretor.py b/src/util/torInterpretor.py index fc217f3..2c4e7fa 100644 --- a/src/util/torInterpretor.py +++ b/src/util/torInterpretor.py @@ -495,9 +495,18 @@ def prompt(): # Cycling history via the readline module with up/down is buggy with a color # prompt.

[arm/master] Source flags for color prompt and hostname lookups

commit 6e88a85a7a8c45d798e8471e9ce27295aa0b122e Author: Damian Johnson <atagar(a)torproject.org> Date: Tue Sep 13 09:34:30 2011 -0700 Source flags for color prompt and hostname lookups Adding source flags for portions of the interpretor that include substantial tradeoffs. For color prompts there's bugs in small displays/huge input, and hostname lookups add a second or two to the runtime of /info queries (otherwise the lookup is instantanious). Defaulting the hostname lookups to be disabled for now.

And in the future there may be a TIMBB and who knows what other packages. Time to give up the guessing game. The language code is something we can identify for certain.
