A better prompt for IPython interactive shell.

• Adds the current path if it changes from the default
• Replaces the less useful In[x]: prompt (we keep the Out[x], which you are more likely to want to reference) with the classic >>>.
• Formats the vi mode nicely if vi mode is set
• Adds the execution time for the previous command if above a minimum delta (by default 5).

To easily get the theme installed and loading at startup:

pip install richprompt[hook]
python -m ipython_startup_hook.install

Install using pip:

pip install richprompt 

or with conda:

conda install -c lewisacidic richprompt

Load the prompt with IPython magic:

%load_ext richprompt

To set the prompt back to what you had previously:

%unload_ext richprompt

You can either put the following snippet in your IPython startup directory (usually $HOME/.ipython/profile_default/startup):

try:
    from richprompt.startup import load
    load()
    del load  # don't pollute global namespace!!
except ModuleNotFoundError:
    pass

Or use ipython-startup-hook (recommended if you use IPython within virtual or conda environments).

This may be done at install with the command given in the Quickstart.

Create the conda environment:

conda env create -f envs/dev.yml
conda activate richprompt-dev

Format code by running the pre-commit tasks:

pre-commit run --all

Run the tests with pytest (note we need to use ipython rather than python for these tests as we need the IPython runtime):

ipython -m pytest
