## Installation
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-0.6.0-x86_64-Windows.msi](https://github.com/dynobo/normcap/releases/download/v0.6.0/NormCap-0.6.0-x86_64-Windows.msi)
(Installer)
- [NormCap-0.6.0-x86_64-Windows.zip](https://github.com/dynobo/normcap/releases/download/v0.6.0/NormCap-0.6.0-x86_64-Windows.zip)
(Portable)
#### Linux
It's recommended to install NormCap from [Flathub](https://flathub.org):
```sh
flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
flatpak install flathub com.github.dynobo.normcap
```
<a href="https://flathub.org/apps/details/com.github.dynobo.normcap"><img src="https://flathub.org/assets/badges/flathub-badge-en.png" width="160"/></a>
Alternative options:
- [NormCap-0.6.0-x86_64.AppImage](https://github.com/dynobo/normcap/releases/download/v0.6.0/NormCap-0.6.0-x86_64.AppImage) - ⚠️ ***deprecated***
(Requires [fuse](https://dynobo.github.io/normcap/faqs/#linux-appimage-error-appimages-require-fuse-to-run))
- [`normcap` @ AUR](https://aur.archlinux.org/packages/normcap) (Arch/Manjaro)
#### macOS
**Note:** You must allow the unsigned application on first start: "System Preferences" →
"Security & Privacy" → "General" → "Open anyway". You also need to allow NormCap to take
screenshots. ([#135](https://github.com/dynobo/normcap/issues/135))
- [NormCap-0.6.0-x86_64-macOS.dmg](https://github.com/dynobo/normcap/releases/download/v0.6.0/NormCap-0.6.0-x86_64-macOS.dmg)
(Installer for x86/64)
- [NormCap-0.6.0-arm64-macOS.dmg](https://github.com/dynobo/normcap/releases/download/v0.6.0/NormCap-0.6.0-arm64-macOS.dmg)
(Installer for M1)
## Use Python package
As an _alternative_ to the prebuilt packages above, you can install the
[NormCap Python package](https://pypi.org/project/normcap/) for **Python >=3.9**, but it
requires more setup:
#### 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 the Tesseract base folder. It should contain a `/tessdata` subfolder
and the `tesseract.exe` binary. Depending on whether you installed Tesseract system-wide or
in userspace, the base folder should be:
```
C:\Program Files\Tesseract-OCR
```
or
```
C:\Users\<USERNAME>\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
```
## Development
Prerequisites for setting up a development environment:
[**Python >=3.9**](https://www.python.org/downloads/),
[**uv**](https://docs.astral.sh/uv/getting-started/installation/), and
[**Tesseract >=5.0**](https://tesseract-ocr.github.io/tessdoc/#5xx) (including **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
uv sync
# Register pre-commit hook
uv run pre-commit install
# Run NormCap in virtual env
uv run python -m normcap
```
## Contribute to UI translations
Please use [Weblate](https://hosted.weblate.org/projects/normcap/ui/) to complement or
correct text for existing languages as well as for adding new languages.
(If you prefer not to use Weblate, you can also [do it manually](./normcap/resources/locales/README.md), but be aware that this is more cumbersome.)
## 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_
- [zxing-cpp](https://github.com/zxing-cpp/zxing-cpp) - _QR & barcode detection_
- [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!
