bpython v0.13 Release Notes

  • 🛠 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)

    🛠 Fixes:

    • 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.
    • FakeStream has flush(), so works correctly with 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
