bpython: A fancy curses interface to the Python interactive interpreter

bpython is a lightweight Python interpreter that adds several features common to IDEs. These features include syntax highlighting, expected parameter list, auto-indentation, and autocompletion. (See below for example usage).

bpython does not aim to be a complete IDE - the focus is on implementing a few ideas in a practical, useful, and lightweight manner.

bpython is a great replacement to any occasion where you would normally use the vanilla Python interpreter - testing out solutions to people's problems on IRC, quickly testing a method of doing something without creating a temporary file, etc..

You can find more about bpython - including full documentation - at our homepage.

Installation & Basic Usage

Installation using Pip

If you have pip installed, you can simply run:

$ pip install bpython

Start bpython by typing bpython in your terminal. You can exit bpython by using the exit() command or by pressing control-D like regular interactive Python.

Installation via OS Package Manager

The majority of operating system of desktop computers comes with a package manager system, if you are any user of them, you can install bpython using the package manager.

Ubuntu/Debian

Ubuntu/Debian family Linux users and install bpython using the apt package manager, using the command with sudo privilege:

$ apt install bpython

In case you are using an older version, run

$ apt-get install bpython

Arch Linux

Arch linux uses pacman as the default package manager, and you can use it to install bpython:

$ pacman -S bpython

Windows

Caveats: As bpython makes use of the ncurses library of *nix-family operating systems, bpython on Windows is not officially supported and tested.

However, you can still use bpython on Windows using a somewhat work around. Briefly, you should install these two packages using pip:

$ pip install bpython windows-curses

Then you should invoke a program called bpython-curses.exe instead of bpython.exe to use bpython:

$ bpython-curses

Mac OS

Like Windows, Mac OS does not include a package manager by default. If you have installed any third-party package manager like MacPorts, you can install it via

$ sudo port install py-bpython

Features & Examples

Readline-like autocomplete, with suggestions displayed as you type.
In-line syntax highlighting. This uses Pygments for lexing the code as you type, and colours appropriately.
Expected parameter list. As in a lot of modern IDEs, bpython will attempt to display a list of parameters for any function you call. The inspect module is tried first, which works with any Python function, and then pydoc if that fails.
Rewind. This isn't called "Undo" because it would be misleading, but "Rewind" is probably as bad. The idea is that the code entered is kept in memory and when the Rewind function is called, the last line is popped and the entire session is re-evaluated. Use <control-R> to rewind.
Edit the current line or your entire session in an editor. F7 opens the current session in a text editor, and if modifications are made, the session is rerun with these changes.
Pastebin code/write to file. Use the <F8> key to upload the screen's contents to pastebin, with a URL returned.
Reload imported Python modules. Use <F6> to clear sys.modules and rerun your session to test changes to code in a module you're working on.

Configuration

See the sample-config file for a list of available options. You should save your config file as ~/.config/bpython/config (i.e. $XDG_CONFIG_HOME/bpython/config) or specify at the command line:

bpython --config /path/to/bpython/config

Dependencies

Pygments
curtsies >= 0.3.5
greenlet
pyxdg
requests
Sphinx >= 1.5 (optional, for the documentation)
babel (optional, for internationalization)

CLI Windows Support

Dependencies

Curses Use the appropriate version compiled by Christoph Gohlke.

pyreadline Use the version in the cheeseshop.

Current version is tested with

Curses 2.2
pyreadline 1.7

Curses Notes

The curses used has a bug where the colours are displayed incorrectly:

red is swapped with blue
cyan is swapped with yellow

To correct this I have provided a windows.theme file.

This curses implementation has 16 colors (dark and light versions of the colours)

Alternatives

ptpython

IPython

Feel free to get in touch if you know of any other alternatives that people may be interested to try.

Mac OS X: Mouse Scrolling triggers command history instead of scrolling the window

Hi there,

I have to say that this is a bit annoying, as bpython (the shell variant) is one of the very few applications that redefine scroll wheel events in this way.

I am quite sure that this is a setting that can be changed - but the point of this bug report is that the default for that setting should really be to let the scroll wheel, well, scroll the window.

Instead what happens is that I scroll through the history of the commands I have invoked previously. True, that can also be interesting, but I am already perfectly capable of doing that with the up down arrows on my keyboard, which I need to use anyway when I want to execute commands.

So please change the default for the scroll wheel to actually scrolling the window.

Something about boto3 crashes bpython

I don't know enough to debug this further. I'm hoping someone can help because I really rely on bpython to explore and develop using libraries I don't know.

Steps to reproduce:

Brackets completion

Solution for #905

As requested, posted here for feedback (still needs polishing, more docs and tests).

Changes include traditional IDEs behavior on completing brackets ( [ { and quotes " '. This works in writing, as well as with callable autocomplete matches.

Example: If you type in def foo(, the line will print def foo() and put the cursor between the brackets. This also works with nested brackets and quotes. So if you do x = 5*(some_list[5]), the brackets will close upon writing the starting paren/quote, and put your cursor inside them.

I also implemented behavior on BACKSPACE key and TAB key. If your cursor is currently positioned right on the character, which is a closing bracket or a quote and you hit TAB, your cursor will move behind that symbol. If you hit BACKSPACE and the first character to be deleted is an opening bracket, and your cursor is on a closing bracket, this will delete both brackets/quotes. This behavior also works in nested brackets environment.

Feature can be enabled in config file by setting the brackets_completion flag to True.

Thank you for the feedback.

Still needs tests. Guidance or advice appreciated.

Cannot show most source code
Some examples:

> def fnord(): pass > fnord<f2> # doesn't work > class Foo(object): pass > Foo<f2> # doesn't work

Both of these work fine in iPython. Putting these two definitions in a file and importing them yields the same result - source does not show.

These are reduced examples, in my testing I noticed that I could show the source of a whole class in my project, but I wasn't able to show most of the methods on it. Some examples: properties, decorated methods, inherited methods.

Not sure whats the reason for this, but iPython did work for those most of the time, so it may be a good idea to fork their method source lookup code and use it instead of what is in bpython right now.

Autocomplete for lists, tuples - autocomplete could work for items in lists, tuples, etc #37

This handles part of #37.

It so far works with array indexing (lists and tuples). It was tested mainly for strings and objects. It does support nesting of arrays: a[0][0].

I will later looking into supporting dictionaries, and possibly inline creation of data structures.

Ctrl-Y in OS X causes bpython to suspend

When I'm in bpython repl I used to press Ctrl-y to paste stuff from my yank-ring.

But with the new curtsies UI, when I press C-y bpython is suspended. When I type fg to bring it to foreground it crashes.

If I suspend it using C-z, I'm able to resume it without trouble when I do fg.

I tried this in a linux machine (via docker) and Ctrl-y seems to be working fine.

Allow bpython/bpdb outside main thread

Because signal.signal is only allowed to be called from the main thread, if you use bpdb in another thread it will crash upon entering the repl. By ignoring the resulting ValueError the show can go on.

This makes bpdb useful in Django's runserver, even with threading and/or live reload on.

A question is what to tell the user when this happens? Just ignore it like here, or log something? What on which level?

Feedback much appreciated.

Allowing to navigate through code by ctrl+arrows

readline keybindings do not work
Apparently readline keybindings do not work (C-n, C-p, etc..). This is on ActivePython/Linux with the readline module installed.

IPython readline keybindings works well on the same Python interpreter.

This project looks amazing that I might contribute some code.... so perhaps I'll fix this issue myself in free time.

Support absolute paths in import completion skip list
I get the high CPU from file scanning mentioned in https://github.com/bpython/bpython/issues/845 and https://github.com/bpython/bpython/issues/806 .

This surprised me because it must have started after an update and the first symptom was my CPU fan spinning on my MBP.

Is there any way to disable this scanning in my home dir? As another user mentioned, it's common to open bpython in the home dir, and people often have many repos checked out below their home dir.

A config option in the config file? A dot-file? Something in the .python-profile.py?

Is there any way to to this today? If not, I would like to request the feature.

Disable terminal default ctrl-s behavior so it can be used for save.

Solution for https://github.com/bpython/bpython/issues/638

Terminal emulators typically "freeze" the terminal on ctrl-s and continue on ctrl-q. You can run stty -ixon in your terminal or add it to your .bashrc or similar to disable this behavior on ctrl-s. If not disabled, users of bpython can't use ctrl-s to save their session.

I think we should do the equivalent of this for users automatically. I would guess that more users are annoyed by it but never report than users that want to use scroll control in bpython. I don't think this default behavior of ctrl-s/ctrl-q is very useful in bpython, especially since our output is much slower than python. However ptpython has a similar issue that it also chooses not to automatically fix.

Hitting F7 is a workaround that opens the current session in a text editor, from which you can save it with a new name. Saving without changing the name saves to a temporary file and re-executes the modified session.

Note that the say that the way Curtsies implements this behavior is not by turning off this terminal feature (-ixon and -ixoff) but rather by making ctrl-s and ctrl-q no longer do these things.

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
