Configuration

You can edit the config file by pressing F3 (default). If a config file does not exist you will asked if you would like to create a file. By default it will be saved to $XDG_CONFIG_HOME/.config/bpython/config [1].

General

This refers to the [general] section in your $XDG_CONFIG_HOME/bpython/config file.

arg_spec

Display the arg spec (list of arguments) for callables, when possible (default: True).

auto_display_list

Display the autocomplete list as you type (default: True). When this is off, you can hit tab to see the suggestions.

autocomplete_mode

There are three modes for autocomplete. simple, substring, and fuzzy. Simple matches methods with a common prefix, substring matches methods with a common subsequence, and fuzzy matches methods with common characters (default: simple).

As of version 0.14 this option has no effect, but is reserved for later use.

New in version 0.12.

color_scheme

See Themes for more information.

Color schemes should be put in $XDG_CONFIG_HOME/bpython/. For example, to use the theme $XDG_CONFIG_HOME/bpython/foo.theme set color_scheme = foo

Leave blank or set to “default” to use the default (builtin) theme.

Whether magic methods should be auto completed (default: True).

dedent_after

pastebin_helper

The name of a helper executable that should perform pastebin upload on bpython’s behalf. If set, this overrides pastebin_url. It also overrides pastebin_show_url, as the helper is expected to return the full URL to the pastebin as the first word of its output. The data is supplied to the helper via STDIN.

An example helper program is pastebinit, available for most systems. The following helper program can be used to create gists:

#!/usr/bin/env python

import sys
import urllib2
import json

def do_gist_json(s):
    """ Use json to post to github. """
    gist_public = False
    gist_url = 'https://api.github.com/gists'

    data = {'description': None,
            'public': None,
            'files' : {
                'sample': { 'content': None }
            }}
    data['description'] = 'Gist from BPython'
    data['public'] = gist_public
    data['files']['sample']['content'] = s

    req = urllib2.Request(gist_url, json.dumps(data), {'Content-Type': 'application/json'})
    try:
        res = urllib2.urlopen(req)
    except HTTPError, e:
        return e

    try:
        json_res = json.loads(res.read())
        return json_res['html_url']
    except HTTPError, e:

if __name__ == "__main__":
  s = sys.stdin.read()
  print do_gist_json(s)
