get-unicode-arguments-to-launch-editor

A cross-platform Python utility that gets Unicode arguments to launch an EDITOR, using user input, environment variables, and platform-specific fallbacks.

Features

• Gets arguments to launch an EDITOR using (in order of precedence):
  1. User-supplied command (editor parameter)
  2. $VISUAL environment variable
  3. $EDITOR environment variable
  4. Platform-specific fallbacks:
     • NT: notepad
     • POSIX: nano, vi
• Verifies that the editor executable exists on the system.
• Canonicalizes the returned command as a list suitable for os.execvp() or subprocess calls.
• Command-line splitting and executable resolution is platform-aware.

Installation

pip install get-unicode-arguments-to-launch-editor

Usage

# coding=utf-8
from __future__ import print_function
from get_unicode_arguments_to_launch_editor import get_unicode_arguments_to_launch_editor

# Example output on Linux:
# [u'/usr/bin/nano']
print(get_unicode_arguments_to_launch_editor())

# Example output on Linux:
# [u'/usr/bin/vim.basic', u'-R']
print(get_unicode_arguments_to_launch_editor(u'vim -R'))
