Description
===========

Need to do a quick calculation during your brew day?
Don't fancy digging through a GUI application, or a web based tool?
Prefer to do simple things in a terminal?

Then **brew-tools** is for you.

Currently brew-tools includes:

* ABV calculator
* Keg priming calculator
* Priming sugar calculator
* Quick infusion calculator
* Adjust gravity with dme calculator
* Apparent and Real attenuation calculator
* Final gravity from a given attenuation percentage
* Gravity adjustment by boil off/dilution calculator
* New gravity after volume adjustment
* Strike water temp calculator
* Strike water temperature
* Simple unit converter

More to come

See the [changelog](CHANGELOG.rst) for updates in each version

Installation
============

Brew-tools is available from PyPI

    pip install brew-tools

You can also clone/download this repository and install it using pip

    cd <brew-tools-dir>
    pip install .

Usage
=====

When first starting Brew tools you will be asked for your preferred unit type, metric or imperial.
This is then stored in a config file and used as the default unit. This can be temporarily
changed with the `--unit` option.

and also for its commands

```
brew-tools infuse --help
Usage: brew-tools infuse [OPTIONS]

Options:
  -temp FLOAT    Current temperature of mash
  -target FLOAT  Target temperature of mash
  -ratio FLOAT   Grist/water ratio
  -grain FLOAT   Weight of grain in mash
  -water FLOAT   Temp of infusion water
  --help         Show this message and exit.
```

If the inputs are not passed via the command line arguments, brew tools will
prompt the user for input.

For more information see the [documentation](https://brew-tools.readthedocs.io/en/latest/)

Development
===========

If you want to help develop brew tools you should install it into a
virtual environment. The current version of brew-tools uses [uv](https://docs.astral.sh/uv) 
to manage virtual environments and such.

In order to start, [install uv](https://docs.astral.sh/uv/getting-started/installation/)
and change into the brew-tools directory. From there you can run

    uv sync

which will create a virtual environment and install the dependencies as well as install
`brew_tools` to the environment.
To run `brew_tools` in the development environment run

    uv run brew_tools

Which will launch  `brew_tools`. Simply add arguments to the end of the line.

To run the tests you use

    uv run pytest tests

In addition to the tests it's advisable to run a linter of the source as Github actions
will also check for linting and formatting errors.

    rye run ruff format --check src tests

or if you want to format the files automatically

    rye run ruff format src tests

For linting use

    rye run ruff check src tests
