bpython-config - Man Page

user configuration file for bpython

Synopsis

$XDG_CONFIG_HOME/bpython/config

Description

The configuration file contains various options controlling the behaviour of bpython.

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 four modes for autocomplete: none, 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). None disables autocompletion.

Added in version 0.12.

brackets_completion

Whether opening character of the pairs (), [], "", and '' should be auto-closed (default: False).

Added in version 0.23.

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.

complete_magic_methods

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

dedent_after

Number of blank lines required before next line will be dedented (default: 1). If set to 0, automatic dedenting never occurs.

editor

Editor for externally editing the current line, session, or config file.

Added in version 0.13.

flush_output

Whether to flush all output to stdout on exit (default: True).

Only relevant to bpython-curses and bpython-urwid.

highlight_show_source

Whether the source code of an object should be syntax highlighted (default: True).

hist_duplicates

Whether to store duplicate entries in the history (default: True).

hist_file

History file (default: ~/.pythonhist).

hist_length

Number of lines to store in history (set to 0 to disable) (default: 100).

paste_time

The time between keypresses before pastemode is deactivated in bpython-curses (default: 0.02).

pastebin_confirm

Whether pasting to a pastebin needs to be confirmed before sending the data (default: True).

pastebin_expiry

Time duration after which a paste should expire. Valid values are 1day, 1week and 1month (default: 1week).

Added in version 0.14.

pastebin_helper

The name of a helper executable that should perform pastebin upload on bpython's behalf. If set, this overrides pastebin_url. 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 requests
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": "Gist from bpython",
        "public": gist_public,
        "files": {
            "sample": {
                "content": s
            },
        },
    }

    headers = {
        "Content-Type": "application/json",
        "X-Github-Username": "YOUR_USERNAME",
        "Authorization": "token YOUR_TOKEN",
    }

    try:
        res = requests.post(gist_url, data=json.dumps(payload), headers=headers)
        res.raise_for_status()
        json_res = json.loads(res.read())
        return json_res["html_url"]
    except requests.exceptions.HTTPError as err:
        return err


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

Added in version 0.12.

pastebin_url

The pastebin url to post to (without a trailing slash). This pastebin has to be a pastebin which provides a similar interface to bpaste.net's JSON interface (default: https://bpaste.net).

save_append_py

Whether to append .py to the filename while saving the input to a file.

Added in version 0.13.

single_undo_time

Time duration an undo must be predicted to take before prompting to undo multiple lines at once. Use -1 to never prompt, or 0 to always prompt. (default: 1.0)

Sample Config

# This is a standard Python config file.
# Valid values can be True, False, integer numbers, and strings.
# Lines starting with # are treated as comments.
#
# By default bpython will look for $XDG_CONFIG_HOME/bpython/config
# ($XDG_CONFIG_HOME defaults to ~/.config) or you can specify a file with the
# --config option on the command line.
#
# See http://docs.bpython-interpreter.org/configuration.html for all
# configurable options.
