Crop GUI Neu — FAQ

Table of Contents

General

Why did you choose this name?

"Neu" is German for "new".

I was looking for a short and descriptive name. It isn’t the most creative name and it sounds a bit awkward, but so does "Helvetica Neue". If anyone wants to create a better tool, please do, I left "Crop GUI Neo" free just for you.

Why build it?

This is an attempt to re-implement an already existing solution: github.com/jepler/cropgui/

I wanted to avoid executing non-standard installer scripts on my new Linux installations. After looking around for alternative solutions or how the repository could be improved, I decided to start with a new project.

This script does not have feature parity yet.

At first, it looked like an easy project, until I tried to replace exiftool and pulled in a lot of dependencies for what was just a little Perl script. I will eventually rewrite parts when I learn new languages, but don’t expect this to be completed any time soon.

Installer Script

The original installation script for Crop GUI is a bit difficult to read and understand. I made a new version which also includes an uninstall option.

Important: This script is for the old version of Crop GUI by jepler. My version uses either Pipx or Flatpak for installation.

You can find the script here: /assets/cropgui_install.sh

The style if the script is defined by shfmt in pre-commit with a few parameters that I prefer.

Development

Building with Flatpak

Dependencies:

  • python3-requirement-parser on Ubuntu to run flatpak-pip-generator.py with Pip.

  • python3-toml on Ubuntu to run flatpak-poetry-generator.py with Poetry.

# Clean environment and install dependencies.
# rm poetry.lock && poetry env remove --all
# poetry install

# Create requirements file for pip.
pipx run \
  https://github.com/lwbt/flatpak-builder-tools/raw/master/pip/flatpak-pip-generator.py \
  --runtime='org.freedesktop.Sdk' --requirements-file='requirements.txt'

# Create requirements file for poetry. (Not fully implemented yet, fails to build.)
# pipx run \
#   https://github.com/flatpak/flatpak-builder-tools/raw/master/poetry/flatpak-poetry-generator.py \
#  "poetry.lock"
# pipx run \
#  https://github.com/GabMus/flatpak-builder-tools/raw/master/poetry/flatpak-poetry-generator.py \
#  "poetry.lock"

flatpak --user install \
  org.gnome.Platform/x86_64/46
  org.gnome.Sdk/x86_64/46 \

# Install with pipx
# pipx install .
