There are a few new features, a bunch of bugfixes, and a new frontend
for bpython in this release.
* Dictionary key completion, thanks to Maja Frydrychowicz (#226).
  To use normal completion and ignore these key completions, type a space.
* Edit current line in external editor: ctrl-x (#161)
* Python 2.5 compatibility, thanks to Michael Schuller (#279). Python 2.5
  is not officially supported, but after few changes Michael introduced, he
  says it's working fine.

  django.core.email.backends.console thanks to Marc Sibson (#259)
* FakeStdin has fileno() (#232)
* Changes to sys.ps1 and sys.ps2 are respected thanks to Michael Schulle (#267)
* atexit registered functions run on exit (#258)
* fixed an error on exit code when running a script with bpython script.py (#260)
* setup.py extras are used to define dependencies for urwid and
  curtsies frontends
There's a new frontend for bpython: bpython-curtsies. Curtsies is a terminal
wrapper written to making native scrolling work in bpython. (#56, #245)
Try bpython-curtsies for the bpython experience with a vanilla python
layout. (demo:
http://ballingt.com/assets/bpython-curtsies-scroll-demo-large.gif)
This curtsies frontend addresses some issues unfixed in bpython-cli, and has
a few extra features:
* Editing full interpreter history in external editor with F7, which is rerun
  as in rewind
* A new interpreter is used for rewind, unless bpython-curtsies was started
  with custom locals or in interactive mode (#71)
* Ctrl-c behaves more like vanilla python (#177)
* Completion still works if cursor at the end of the line (#147)
* Movement keys meta-b, meta-f, and meta-backspace, ctrl-left and ctrl-right
  are all honored (#246, #201)
* Non-ascii characters work in the file save prompt (#236)
* New --type / -t option to run the contents of a file as though they were
  typed into the bpython-curtsies prompt
A few things about bpython-curtsies are worse than regular bpython:
* Bad things can happen when using several threads (#265)
* output prints slowly (#262)
* bpython-curtsies can't be backgrounded and resumed correctly (via ctrl-z,
  fg) (#274)
There are two new options in the new [curtsies] section of the bpython config
* list_above: whether completion window can cover text above the current line;
  defaults to True
* fill_terminal: whether bpython-curtsies should be fullscreen (like bpython);
  defaults to False
We want to give special thanks to the Hacker School project-
(https://www.hackerschool.com/) for choosing bpython as their pet hacking
project. In special we would like to thank the following people for contributing
their code to bpython:
- Martha Girdler
- Allison Kaptur
- Ingrid Cheung
We'd also like to thank Eike Hein for contributing his pastebin code which now
makes it possible to paste using a 3rd party program unlocking a whole slew of
pastebins for bpython users.
* Added a new pastebin_helper config option to name an executable that should
  perform pastebin upload on bpython's behalf. If set, this overrides
  pastebin_url. Data is supplied to the helper via STDIN, and it is expected
  to return a pastebin URL as the first word of its output.
* Fixed a bug causing pastebin upload to fail after a previous attempt was
  unsuccessful. A duplicate pastebin error would be displayed in this case,
  despite the original upload having failed.
* Added more key shortcuts to bpython.urwid
* Smarter dedenting after certain expressions
* #74 fixed broken completion when auto_display_list was disabled
We also have done numerous cleanup actions including building the man pages from
our documentation. Including the documentation in the source directory. Some
minor changes to the README to have EOL 79 and changes to urwid to work better
without twisted installed.
* Fix ungetch issues with Python 3.3. See issues #230, #231.
A bugfix/cleanup release .The fixed bugs are:
* #204: "import math" not autocompleting on python 3.2
Otherwise lots of small additions to the to be replacement for our ncurses
frontend, the urwid frontend.
I'd like to specifically thank Amjith Ramanujam for his work on history search
which was further implemented and is in working order right now.
A bugfix release. The fixed bugs are:
* #197: find_modules crashes on non-readable directories
* #198: Source tarball lacks .po files
As a highlight of the release, Michele Orrù added i18n support to bpython.
Some issues have been resolved as well:
* Config files are now located according to the XDG Base Directory
  Specification. The support for the old bpythonrc files has been
  dropped and ~/.bpython.ini as config file location is no longer supported.
  See issue #91.
* Fixed some issues with tuple unpacking in argspec. See issues #133 and #138.
* Fixed a crash with non-ascii filenames in import completion. See issue #139.
* Fixed a crash caused by inspect.findsource() raising an IndexError
  which happens in some situations. See issue #94.
* Non-ascii input should work now under Python 3.
* Issue #165: C-a and C-e do the right thing now in urwid.
* The short command-line option "-c config" was dropped as it conflicts with
  vanilla Python's "-c command" option. See issue #186.
A bugfix release. The fixed bugs are:
* #128: bpython-gtk is broken
* #134: crash when using pastebin and no active internet connection
Well guys. It's been some time since the latest release, six months have passed
We have added a whole slew of new features, and closed a number of bugs as well.
We also have a new frontend for bpython. Marien Zwart contributed a urwid
frontend as an alternative for the curses frontend. Be aware that there still
is a lot to fix for this urwid frontend (a lot of the keyboard shortcuts do not
yet work for example) but please give it a good spin. Urwid also optionally
integrates with a Twisted reactor and through that with things like the GTK
event loop.
At the same time we have done a lot of work on the GTK frontend. The GTK
frontend is now 'usable'. Please give that a spin as well by running bpython-gtk
on you system.
We also welcome a new contributor in the name of Michele Orrù who we hope will
help us fix even more bugs and improve functionality.
As always, please submit any bugs you might find to our bugtracker.
* Pastebin confirmation added; we were getting a lot of people accidentally
  pastebinning sensitive information so I think this is a good idea.
* Don't read PYTHONSTARTUP when executed with -i.
* BPDB was merged in. BPDB is an extension to PDB which allows you to press B
  in a PDB session which will let you be dropped into a bpython sessions with
  the current PDB locals(). For usage, see the documentation.
* The clear word shortcut (default: C-w) now deletes to the buffer.
* More tests have been added to bpython.
* The pastebin now checks for a previous paste (during the session) with the
  exact same content to guard against twitchy fingers pastebinning multiple
* Let import completion return "import " instead of "import".
* GTK now has pastebin, both for full log as well as the current selection.
* GTK now has write2file.
* GTK now has a menu.
* GTK now has a statusbar.
* GTK now has show source functionality.
* GTK saves the pastebin url to the clipboard.
* GTK now has it's own configuration section.
* Set focus to the GTK text widget to allow for easier embedding in PIDA and
  others which fixes issues #121.
* #87: Add a closed attribute to Repl to fix mercurial.ui.ui expecting stderr
  to have this attribute.
* #108: Unicode characters in docsrting crash bpython
* #118: Load_theme is not defined.
* #99: Configurable font now documented.
* #123: <F8> Pastebin can't handle 'ESC' key
* #124: Unwanted input when using <arrow>/<FXX> keys in the statusbar prompt.
Unfortunately another bugfix release as I (Bob) broke py3 support.
* #84: bpython doesn't work with Python 3
       Thanks very much to Henry Prêcheur for both the bug report and the
       patch.
A quick bugfix release (this should not become a habit).
* #82: Crash on saving file.
A bugfix/feature release (and a start at gtk). Happy Christmas everyone!
* #67: Make pastebin URL really configurable. 
* #68: Set a__main__ module and set interpreter's namespace to that module.
* #70: Implement backward completion on backward tab. 
* #62: Hide matches starting with a _ unless explicitly typed.
* #72: Auto dedentation
* #78: Theme without a certain value raises exception

in Debian's bugtracker.
bpython has now some basic support for Python 3 (requires Pygments >=1.1.1).
As a result, setuptools is now optional.
The pastebin URL is now configurable and the default pastebin is now

Probably some other things, but I hate changelogs. :)
It's been a long while since the last release and there've been numerous little
bugfixes and extras here and there so I'm putting this out as 0.8.0. Check the
hg commit history if you want more info:
http://bitbucket.org/bobf/bpython/
Menno sent me some patches to fix some stuff:
* Socket error handled when submitting to a pastebin.
* Resizing could crash if you resize small enough.
Other stuff:
* 'self' in arg list is now highlighted a different colour.
* flush_output option added to config to control whether output is flushed to stdout or not on exit.
* Piping something to bpython made it lock up as stdin was not the keyboard - bpython just executes stdin and exits instead of trying to do something clever.
* Mark Florisson (eggy) gave me a patch that stops weird breakage when unicode objects get added into the output buffer - they now get encoded into the output encoding.
* Bohdan Vlasyuk sent me a patch that fixes a problem with the above patch from Mark if sys.__stdout__.encoding didn't exist.
* Save to file now outputs executable code (i.e. without the >>> and ... and with "# OUT: " prepended to all output lines). I never used this feature much but someone asked for this behaviour.
* Added support for a history file, defaults to ~/.pythonhist and 100 lines but is configurable from the rc file (see sample-rc).
* Charles Duffy has added a yank/put thing - C-k and C-y. He also ran the code through some PEP-8 checker thing and fixed up a few old habits I manage to break but didn't manage to fix the code to reflect this - thank you!
* Jørgen Tjernø has fixed up the autoindentation issues we encountered when bringing soft tabs in.
* SyntaxError, ValueError and OverflowError are now caught properly (code.InteractiveInterpreter treats these as different to other exceptions as it doesn't print the whole traceback, so a different handler is called). This was discovered as I was trying to stop autoindentation from occurring on a SyntaxError, which has also been fixed.
* '.' now in sys.path on startup.
C-d behaviour changed so it no longer exits if the current line isn't empty.
Extra linebreak added to end of stdout flush.
pygments and pyparsing are now dependencies.
Jørgen Tjernø has done lots of cool things like write a manpage and .desktop
file and improved the way tabbing works and also added home, end and del key
handling as well as C-w for deleting words - thanks a lot!
raw_input() and all its friends now work fine.
PYTHONSTARTUP handled without blowing up on stupid errors (it now parses the
file at once instead of feeding it to the repl line-by-line).
KeyboardInterrupt handler clears the list window properly now.
Forgot to switch rpartition to split for 2.4 compat.
The help() now works (as far as I can see) exactly the same
as the vanilla help() in the regular interpreter. I copied some
code from pydoc.py to make it handle the special cases, e.g.
help('keywords')
help('modules')
Somehow it escaped my attention that the list window was never
fully using the rightmost column, except for the first row. This
is because me and numbers don't have the best relationship. I think
stability is really improving with the latest spat of bugfixes,
keep me informed of any bugs.
No noticeable changes except that bpython should now work with
Python 2.4. Personally I think it's silly to make a development
tool work with an out of date version of Python but some people
seem to disagree. The only real downside is that I had to do a
horrible version of all() using reduce(), otherwise there's no
real differences in the code.
Now you can configure a ~/.bpythonrc file (or pass a rc file at the
command line (bpython /foo/bar). See README for details.
help() actually displays the full help page, and I fixed up the
ghetto pager a little.
Now you can hit tab to display the autocomplete list, rather than
have it pop up automatically as you type which, apparently, annoys
A few people have commented that the help() built-in function
doesn't work so well with bpython, since Python will try to output
the help string to PAGER (usually "less") which obviously makes
everything go wrong when curses is involved. With a bit of hackery
I've written my own ghetto pager and injected my own help function
into the interpreter when it initialises in an attempt to rectify this.
As such, it's pretty untested but it seems to be working okay for me.
Suggestions/bug reports/patches are welcome regarding this.
Well, hopefully we're one step closer to making the list sizing
stuff work. I really hate doing code for that kind of thing as I
never get it quite right, but with perseverence it should end up
being completely stable; it's not the hardest thing in the world.
Various cosmetic fixes have been put in at the request of a bunch
of people who were kind enough to send me emails regarding their
experiences.
PYTHONSTARTUP is now dealt with and used properly, as per the vanilla
interpreter.
It looks like the last release was actually pretty bug-free, aside
from one tiny bug that NEVER ACTUALLY HAPPENS but someone was bugging
me about it anyway, oh well.
It's been quite a long time since the last update, due to several
uninteresting and invalid excuses, but I finally reworked the list
drawing procedures so the crashing seems to have been taken care of
to an extent. If it still crashes, the way I've written it will hopefully
allow a much more robust way of fixing it, one that might actually work.
Thanks to Aaron Gallagher for pointing out a case where the hugely
inefficient list generation routines were actually making a significant
issue; they're much more efficient now and should hopefully not cause
any more problems.
Thanks to Klaus Alexander Seis for the expanduser() patch.
Auto indent works on multiple levels now.
Now with auto-indent. Let me know if it's annoying.
Thanks a lot to Angus Gibson for submitting a patch to fix a problem
I was having with initialising the keyboard stuff in curses properly.
Also a big thanks to John Beisley for providing the patch that shows
a class __init__ method's argspec on class instantiation.
I've fixed up the argspec display so it handles really long argspecs
(e.g. subprocess.Popen()) and doesn't crash if something horrible
happens (rather, it avoids letting something horrible happen).
I decided to add a key that will get rid of the autocomplete window,
since it can get in the way. C-l seemed like a good choice, since
it would work well as a side-effect of redrawing the screen (at 
least that makes sense to me). In so doing I also cleaned up a lot
of the reevaluating and resizing code so that a lot of the strange
output seen on Rewind/resize seems to be gone.
The fix for the last bug broke the positioning of the autocomplete
box, whoops.
That pesky bug keeps coming up. I think it's finally nailed but
it's just a matter of testing and hoping. I hate numbers.
I'm having a bit of trouble with some integer division that's
causing trouble when a certain set of circumstances arise,
and I think I've taken care of that little bug, since it's
a real pain in the ass and only creeps up when I'm actually
doing something useful, so I'll test it for a bit and release
it as hopefully a bug fixed version.
A little late in the day to start a changelog, but here goes...
This version fixed another annoying little bug that was causing
crashes given certain exact circumstances. I always find it's the
way with curses and sizing of windows and things...
I've also got bpython to try looking into pydoc if no matches
are found for the argspec, which means the builtins have argspecs
too now, hooray.
