## Report
The report can be found in `/report/`.
The directory contains both the PDF file as well as the LaTex sources.

## Installation
### Requirements:
The following packages required:
- python3.10 or higher
- pip modules:
  - matplotlib
  - numpy
  - textual
  - rich-pixels == 2.2.0
- gddrescue

#### Optionally for development:
- pip:
  - build
  - setuptools
  - textual-dev

### Installing
Installing so it can be used from everywhere with `ddrescue-tui` can be done with `./utilctl install` or manually with `pipx install .` inside of the project directory.
`utilctl` also installs all necessary requirements
I recommend using pipx to avoid possible conflicts

Alternatively, a .whl file can be downloaded from the releases tab and installed with pip.

**For running ddrescue directly, the package has to be run as sudo and therefore also installed with sudo.** 


### Building a binary package
Building a package for binary distribution can be done with: `./utilctl build` or manually with `pipx run build`.

### Troubleshooting
If the command results in a blank terminal, the Python IO encoding might be not set to UTF-8. You can fix this with
`export PYTHONIOENCODING=utf-8` once per terminal session or by prepending the command like this: `PYTHONIOENCODING=utf-8 ddrescue-tui <ARGS>`
