**Tidal Dynamics and Thermal-Orbital Evolution Toolkit Implemented in Cython and Python**

TidalPy is an open source software suite that utilizes a semi-analytic approach to estimate tidal heating,
spin-orbit resonances, tidal & loading Love numbers, and thermal evolution for rocky and icy worlds. It has been used
to simulate the thermal-orbital evolution of moons within our Solar System as well as exoplanets beyond. TidalPy's
`RadialSolver` package can accurately estimate the viscoelastic Love and Shida numbers for a multi-layered, rocky or
icy world, including the effects of liquid layers, compressibility, dynamic tides, and advanced rheological models.
This module has been used to study the tidal response of Mercury, Venus, Earth, our Moon, Mars, and much more.

Have any questions or suggestions? Feel free to leave an [issue](https://github.com/jrenaud90/TidalPy/issues) or send
a message to [TidalPy@gmail.com](mailto:tidalpy@gmail.com).

# Overview

## How to Install

### Compatibility

TidalPy has been developed to work on most modern operating systems. We specifically test it on the latest versions of
Ubuntu, Windows, and MacOS. We also pre-build binaries for these operating systems and provide them via
[PyPI](https://pypi.org/project/TidalPy/) or [Conda-Forge](https://anaconda.org/conda-forge/tidalpy). If a pre-built
binary is not available for your operating system version then see details about
[building TidalPy from source](https://tidalpy.readthedocs.io/en/latest/Overview/Readme.html#building-tidalpy-from-source).

* **Windows-Latest**: [![Windows Tests](https://github.com/jrenaud90/TidalPy/actions/workflows/push_tests_win.yml/badge.svg?branch=main)](https://github.com/jrenaud90/TidalPy/actions/workflows/push_tests_win.yml)
* **MacOS-Latest**: [![MacOS Tests](https://github.com/jrenaud90/TidalPy/actions/workflows/push_tests_mac.yml/badge.svg?branch=main)](https://github.com/jrenaud90/TidalPy/actions/workflows/push_tests_mac.yml)
* **Ubuntu-Latest**: [![Ubuntu Tests](https://github.com/jrenaud90/TidalPy/actions/workflows/push_tests_ubun.yml/badge.svg?branch=main)](https://github.com/jrenaud90/TidalPy/actions/workflows/push_tests_ubun.yml)

### Basic Installation

Installing TidalPy is as simple as ensuring 64-bit [Python 3.9+](https://www.python.org/) is installed on your 
system and running from a terminal:

`pip install TidalPy`

Alternatively you can use conda to install TidalPy:

`conda install -c conda-forge TidalPy`

or 

`mamba install TidalPy`

We recommend using a virtual environments (via a manager like [uv](https://docs.astral.sh/uv/pip/environments/) or
[miniforge](https://conda-forge.org/download/)) when installing TidalPy.

### Accessing Jupyter Notebooks
There are several demos provided with TidalPy that make use of [Jupyter notebooks](https://jupyter.org/) found in
the /Demos/ folder of TidalPy's [repository](https://github.com/jrenaud90/TidalPy). In order to access these you
will need to make sure you install Jupyter and a few related packages:

`pip install ipympl ipython ipywidgets jupyter`

or 

`conda install ipympl ipython ipywidgets jupyter`

You can then clone TidalPy's GitHub repository,

`git clone https://github.com/jrenaud90/TidalPy`

to a local directory. Navigate to this directory and the `Demos` sub-directory then access the notebooks by using the
command, `jupyter notebook`.

### Cartopy

TidalPy offers the ability to make 2D surface projection plots using the
[cartopy](https://scitools.org.uk/cartopy/docs/latest/index.html) package. In turn, cartopy relies on 
[GEOS](https://trac.osgeo.org/geos/) which is not a python package and must be installed outside of pip.

#### Installing Cartopy using `conda`
The easiest way to install cartopy is using a conda environment by,

`conda install -c conda-forge cartopy`

#### Installing Cartopy using `pip`
If you are not using a conda environment then you will need to find and install the GEOS binaries manually:

**Windows:** [Follow instructions here](https://trac.osgeo.org/osgeo4w/)
**On Ubuntu:** `sudo apt-get install libgeos-dev`
**On MacOS:** `brew install geos`

After GEOS is installed you can pip install the rest,

`pip install pyproj shapely pyshp cartopy`

### Installation Troubleshooting

_If you ran into a problem that is not listed below please [submit an issue](https://github.com/jrenaud90/TidalPy/issues) and we will work on addressing it!_

**Known Problems:**
* The `setuptools` package is required before TidalPy can be installed. Usually it is automatically installed, but if
  you are starting with a clean virtual environment it may not have been.
  * For conda: `conda install setuptools`
  * Or pip: `pip install setuptools`

### Building TidalPy from Source
We automatically provide pre-built binaries for the latest version of MacOS, Ubuntu, and Windows via 
[PyPI](https://pypi.org/project/TidalPy/) or [Conda-Forge](https://anaconda.org/conda-forge/tidalpy). If your OS
version does not have pre-built binaries or if you are running into problems with the pre-builds, then you can build
TidalPy from its source code.

To do so, you will need to make sure that your environment has access to a C and C++ compiler that supports
C++20 standards, a recent version of Python, and has Cython 3.0+ installed. 

#### PyPI Build from Source
Using the source code uploaded to PyPI by running,

```bash
python -m pip install TidalPy -v --no-binary TidalPy
```

#### GitHub Repo
Alternatively you can clone the latest version of the GitHub repo and build locally,
```bash
git clone https://www.GitHub.com/jrenaud90/TidalPy.git
python -m pip install . -v --no-binary TidalPy  # The . assumes you have navigated to the directory with `pyproject.toml`
```

This is also the approach you would take to build TidalPy if you plan to edit its code. See more details about 
developing TidalPy [here](https://tidalpy.readthedocs.io/en/latest/Overview/Contributing.html).

#### Special consideration for MacOS
On MacOS, If you run into problems installing TidalPy then reinstall using the verbose flag (`pip install -v .`) to
look at the installation log. If you see an error that looks like "clang: error: unsupported option '-fopenmp'" then
you are likely using the default compiler or other compiler that does not support OpenMP. Read more about this issue
[here](https://github.com/facebookresearch/xformers/issues/157) and the steps taken
[here](https://github.com/jrenaud90/CyRK/blob/main/.github/workflows/push_tests_mac.yml). A fix for this issue is to
use `llvm`'s clang compiler. This can be done by doing the following in your terminal before installing TidalPy.

_Note this error can also occur when installing "CyRK" a critical dependency of TidalPy. The fix is the same as below,
just swap out "TidalPy" for "CyRK"._

```bash
brew install llvm
brew install libomp

# If on ARM64 (Apple Silicon) then do:
export LDFLAGS="-L/opt/homebrew/opt/llvm/lib"
export CPPFLAGS="-I/opt/homebrew/opt/llvm/include"
export LDFLAGS="-L/opt/homebrew/opt/libomp/lib"
export CPPFLAGS="-I/opt/homebrew/opt/libomp/include"
export CC=/opt/homebrew/opt/llvm/bin/clang
export CXX=/opt/homebrew/opt/llvm/bin/clang++

# Otherwise change these directories to:
export LDFLAGS="-L/usr/local/opt/llvm/lib"
export CPPFLAGS="-I/usr/local/opt/llvm/include"
export LDFLAGS="-L/usr/local/opt/libomp/lib"
export CPPFLAGS="-I/usr/local/opt/libomp/include"
export CC=/usr/local/opt/llvm/bin/clang
export CXX=/usr/local/opt/llvm/bin/clang++

pip install CyRK --no-binary="CyRK"
```

### TidalPy Versioning
TidalPy uses the major.minor.bugfix versioning scheme. In TidalPy's current state, we only promise to provide support
for the latest version (as found on the [GitHub release page](https://github.com/jrenaud90/TidalPy/releases)).
Therefore, older minor versions may not get critical patches (_e.g._, TidalPy 0.7.x will get patches where 0.6.x will
not even if the patches are applicable to that earlier version). If you would like to see a bug fix back ported to an
older version please open a [issue](https://github.com/jrenaud90/TidalPy/issues). 

In the future we hope to support multiple minor versions of TidalPy. At that time, all supported versions will be
listed in this section.
