XF

XF stands for extra fast. XF imports your key packages on first call, so you don't pay a recurring tax for imports. Usually saves 1-10 seconds per invocation after startup.

Key features

• Comes with two modes: ipython mode and shell mode. Ipython feels like an ipython console; shell operates like a terminal.
• Extensible: we will accept PRs for additional commands. See the commands directory for examples.
• Easily profile any command using the prof prefix.
• Can use your own environment or run in an isolated environment using the --isolated flag.

Who would benefit from this:

• You are a non-python developer using a python cli
• You are a python developer

Who would not benefit from this:

• Production use cases
• Long-running commands where a few seconds of savings don't make a difference
