## Quickstart

Choose **_one_** of the options for a prebuilt release. If you encounter an issue please

take a look at the [FAQs](https://dynobo.github.io/normcap/#faqs) or

[report](https://github.com/dynobo/normcap/issues) it.

#### Windows

- [NormCap-0.5.8-x86_64-Windows.msi](https://github.com/dynobo/normcap/releases/download/v0.5.8/NormCap-0.5.8-x86_64-Windows.msi)

  (Installer)

#### Linux

- [NormCap-0.5.8-x86_64.AppImage](https://github.com/dynobo/normcap/releases/download/v0.5.8/NormCap-0.5.8-x86_64.AppImage)

  (Binary)

#### macOS

Note: You have to allow the unsigned application on first start: "System Preferences" →

"Security & Privacy" → "General" → "Open anyway". You also have to allow NormCap to take

screenshots. ([#135](https://github.com/dynobo/normcap/issues/135))

- [NormCap-0.5.8-x86_64-macOS.dmg](https://github.com/dynobo/normcap/releases/download/v0.5.8/NormCap-0.5.8-x86_64-macOS.dmg)

  (Installer for M1)

## Install Python package

As an _alternative_ to a prebuilt package from above you can install the

[NormCap Python package](https://pypi.org/project/normcap/) for **Python >=3.9**, but it

is a bit more complicated:

#### On Linux

```sh

# Install dependencies (Ubuntu/Debian)

sudo apt install build-essential tesseract-ocr tesseract-ocr-eng libtesseract-dev libleptonica-dev wl-clipboard

## Install dependencies (Arch)

sudo pacman -S tesseract tesseract-data-eng wl-clipboard

## Install dependencies (Fedora)

sudo dnf install tesseract wl-clipboard

## Install dependencies (openSUSE)

sudo zypper install python3-devel tesseract-ocr tesseract-ocr-devel wl-clipboard

# Install normcap

pip install normcap

# Run

./normcap

```

#### On macOS

```sh

# Install dependencies

brew install tesseract tesseract-lang

# Install normcap

pip install normcap

# Run

./normcap

```

#### On Windows

1\. Install `Tesseract 5` by using the

[installer provided by UB Mannheim](https://github.com/UB-Mannheim/tesseract/wiki).

2\. Identify the path to Tesseract base folder. It should contain a `/tessdata` subfolder

and the `tesseract.exe` binary. Depending on if you installed Tesseract system-wide or

in userspace, the base folder should be:

```

C:\Program Files\Tesseract-OCR

```

or

```

C:\Users\\AppData\Local\Programs\Tesseract-OCR

```

3\. Adjust environment variables:

- Create an environment variable `TESSDATA_PREFIX` and set it to _your_ Tesseract base

  folder, e.g.: "System Properties" → Tab "Advanced" → "Environment Variables..." →

  "New..." → Variable: `TESSDATA_PREFIX`, Value: `"C:\Program Files\Tesseract-OCR"`

- Append Tesseract's base folder to the environment variable `PATH`, e.g.: "System

  Properties" → Tab "Advanced" → "Environment Variables..." → Section "User variables"

  → Select `PATH` → "Edit..." → Add a new entry `"C:\Program Files\Tesseract-OCR"`

- To test your setup, open a new `cmd`-terminal and run:

    ```cmd

    tesseract --list-langs

    ```

4\. Install and run NormCap:

```bash

# Install normcap

pip install normcap

# Run

normcap

```

## Why "NormCap"?

See [XKCD](https://xkcd.com):

[![Comic](https://imgs.xkcd.com/comics/norm_normal_file_format.png)](https://xkcd.com/2116/)

## Development

Prerequisites for setting up a development environment are:

[**Python >=3.9**](https://www.python.org/downloads/),

[**hatch**](https://hatch.pypa.io/latest/install/) and

[**Tesseract >=5.0**](https://tesseract-ocr.github.io/tessdoc/#5xx) (incl. **language

data**).

```sh

# Clone repository

git clone https://github.com/dynobo/normcap.git

# Change into project directory

cd normcap

# Create virtual env and install dependencies

hatch env create

# Register pre-commit hook

hatch run pre-commit install

# Run NormCap in virtual env

hatch run python -m normcap

```

## Credits

This project uses the following non-standard libraries:

- [pyside6](https://pypi.org/project/PySide6/) _- bindings for Qt UI Framework_

And it depends on external software:

- [tesseract](https://github.com/tesseract-ocr/tesseract) - _OCR engine_

- [wl-clipboard](https://github.com/bugaevc/wl-clipboard) - _Wayland clipboard

  utilities_

- [xclip](https://github.com/astrand/xclip) - _CLI to the X11 clipboard_

Packaging is done with:

- [briefcase](https://pypi.org/project/briefcase/) _- converting Python projects into_

  _standalone apps_

Thanks to the maintainers of those nice tools!
