### Solve Optimization Problem with PyUNLocBoX

Source: https://pyunlocbox.readthedocs.io

A typical usage example demonstrating how to solve an optimization problem composed of the sum of two convex functions using PyUNLocBoX. It shows instantiation of function and solver objects, and calling the `solve` function.

```python
>>> from pyunlocbox import functions, solvers
>>> f1 = functions.norm_l2(y=[4, 5, 6, 7])
>>> f2 = functions.dummy()
>>> solver = solvers.forward_backward()
>>> ret = solvers.solve([f1, f2], [0., 0, 0, 0], solver, atol=1e-5)
Solution found after 9 iterations:
    objective function f(sol) = 6.714385e-08
    stopping criterion: ATOL
>>> ret['sol']
array([3.99990766, 4.99988458, 5.99986149, 6.99983841])
```

### Define Custom Function in PyUNLocBoX

Source: https://pyunlocbox.readthedocs.io

Example of how to define a custom function by inheriting from `pyunlocbox.functions.func` and implementing the `_eval`, `_grad`, and `_prox` methods.

```python
>>> from pyunlocbox import functions
>>> class myfunc(functions.func):
...     def _eval(self, x):
...         return 0  # Function evaluated at x.
...     def _grad(self, x):
...         return x  # Gradient evaluated at x, if available.
...     def _prox(self, x, T):
...         return x  # Proximal operator evaluated at x, if available.
```

--------------------------------

### Set up Development Environment with UV

Source: https://pyunlocbox.readthedocs.io

Steps to clone the PyUNLocBoX repository and set up a development environment using UV.

```bash
$ git clone https://github.com/epfl-lts2/pyunlocbox.git
$ cd pyunlocbox
$ uv sync --dev
```

--------------------------------

### Build Documentation with Sphinx

Source: https://pyunlocbox.readthedocs.io

Build the project documentation using Sphinx. This command generates HTML documentation from the source files in the 'doc' directory.

```bash
$ uv run sphinx-build -b html doc/ doc/_build/
```

--------------------------------

### Format Code with Black and isort

Source: https://pyunlocbox.readthedocs.io

Apply code formatting using Black for consistent Python style and isort for organizing imports. These commands format the code in the current directory.

```bash
$ uv run black .
$ uv run isort .
```

--------------------------------

### Run Tests with Pytest

Source: https://pyunlocbox.readthedocs.io

Execute the test suite using pytest. This command runs all tests defined in the project.

```bash
$ uv run pytest
```

--------------------------------

### Run All Pre-commit Checks Manually

Source: https://pyunlocbox.readthedocs.io

Manually trigger all pre-commit checks across all files in the repository. This is useful for verifying code quality before committing.

```bash
$ uv run pre-commit run --all-files
```

--------------------------------

### Run Linting with Flake8

Source: https://pyunlocbox.readthedocs.io

Execute the flake8 linter to check for code quality and style issues. The `--doctests` flag includes doctests in the check, and `--exclude` skips specified directories.

```bash
$ uv run flake8 --doctests --exclude=doc,.venv
```

--------------------------------

### Run Tests with Coverage

Source: https://pyunlocbox.readthedocs.io

Run tests with pytest and generate an HTML report for code coverage. This helps identify areas of the code that are not adequately tested.

```bash
$ uv run pytest --cov=pyunlocbox --cov-report=html
```

--------------------------------
