gjenta
Tool for replaying Python REPL sessions.
Quickstart
To see gjenta in action, install it and ask it to "quick play" an example script:
pip install gjenta gjenta quickplay examples/gjenta/simple.py
Installation
Install gjenta
from the PyPI with pip
:
pip install gjenta
From source
Just use pip
again. Run this command from the directory containing
setup.py
:
pip install .
Basic usage
The basic thing to do with gjenta
is to have it replay an existing Python
script through the REPL. There are some scripts in the examples
directory
that you can try. First you need to compile the script to a schedule:
gjenta compile -o commands.sched examples/gjenta/commands.py
Then you can run the schedule with the replay command:
gjenta replay commands.sched
If everything is working properly, you'll see this start a new REPL, enter some commands, and exit the REPL.
Quickplay
You can ask gjenta to compile and run a script all in one pass, without generating the intermediate schedule file, using the quickplay command:
gjenta quickplay example/gjenta/commands.py
This is useful for iterating on scripts during development.
Configuration
Gjenta has fairly sophisticated support for configuring its various plugins. Each plugin specifies its configuration option, and you can provide values via a TOML configuration file.
There is an example configuration file in examples/gjentarc.toml.

Tests
To run the tests you first need to install the testing dependencies:
pip install ".[test]"
Then you can use tox to run everything. For example, to run the tests with Python 3.7:
tox -e py37
