Parallel versions of bpython for Python 2 and 3.

README.md

bpython+

bpython+ is a thin wrapper around the bpython interpreter, which allows the user to specify whether it should be executed with version 2 or 3 of the Python interpreter; the implementation is practically identical to that of pylint+.

requirements

You must have:

• python2 in your $PATH
• python3 in your $PATH
• bpython installed (via pip, and not from your package manager) for Python 2
• pylint installed (via pip3, and not from your package manager) for Python 3

use

Place bpython+ somewhere in your $PATH, and make sure that it has executable permissions. Then:

bpython+ 2|3 [BPYTHON_ARGS]

For instance:

$ bpython+ 2
>>> import sys
>>> sys.version_info
sys.version_info(major=2, minor=7, micro=6, releaselevel='final', serial=0)

$ bpython+ 3
>>> import sys
>>> sys.version_info
sys.version_info(major=3, minor=4, micro=0, releaselevel='final', serial=0)

bpython+

#! /usr/bin/env bash

# Description:
#   A wrapper around bpython that allows the user to specify whether it should
#   be executed with version 2 or 3 of the Python interpreter.
#
# Use:
#   bpython+ PYTHON_VERSION [BPYTHON_ARGS]
#
#   PYTHON_VERSION: Either 2 or 3, for version 2/3 of the Python interpreter.
#   BPYTHON_ARGS: Argument to pass on to bpython.

python_interpreter="python${1}"
bpython_args="${@:2}"
bpython_import=$(cat << PYTHON
import sys
import pkg_resources

__requires__ = "bpython"
sys.exit(
	pkg_resources.load_entry_point("bpython", "console_scripts", "bpython")()
)
PYTHON
)

$python_interpreter -c "$bpython_import" $bpython_args

On Linux shell it may be simpler. For example, on bash follow the steps below for your user:

• Install bpython by pip2 and pip3;
• Add rows to end of .bashrc file:
  alias bpython2='python2 -m bpython'
alias bpython3='python3 -m bpython'
  In my case, i set the 'bpy'-named aliases
• Run as non-priveileged user:
  $ . .bashrc

That's all:
