The Fuck (Python 3.12.X patch)

Forked from nvbn/thefuck.

The Fuck is a magnificent app, inspired by a @liamosaur tweet, that corrects errors in previous console commands.

Is The Fuck too slow? Try the experimental instant mode!

The app seems to work fine on Python 3.13.X and on Python 3.14.X.

How to run the app

1. Install dependencies and install the package (editable mode is recommended while developing):

pip install -r requirements.txt
pip install -e .

2. Configure the shell alias (run in the shell you use):

eval "$(thefuck --alias)"

3. Trigger a fix by running a wrong command, then run:

fuck

4. Optional: verify the CLI is available:

thefuck --help

Creating your own rules

To add your own rule, create a file named your-rule-name.py in ~/.config/thefuck/rules. The rule file must contain two functions:

match(command: Command) -> bool
get_new_command(command: Command) -> str | list[str]

Optional functions and variables:

side_effect(old_command: Command, fixed_command: str) -> None
enabled_by_default
requires_output
priority

Example: prepend sudo on permission errors:

def match(command):
    return ('permission denied' in command.output.lower()
            or 'EACCES' in command.output)

def get_new_command(command):
    return 'sudo {}'.format(command.script)

enabled_by_default = True
priority = 1000
requires_output = True

Experimental instant mode

Instant mode logs output with script then reads the log, skipping slow re-runs. Supports Python 3.12 with bash or zsh. zsh autocorrect must be disabled.

Enable in .bashrc or .zshrc:

eval $(thefuck --alias --enable-experimental-instant-mode)
