Consider conda2appimage

[probonopd]

Similar to pkg2appimage, we could possibly make conda2appimage. Any volunteers?

Thanks @TheAssassin for implementing this in https://github.com/TheAssassin/linuxdeploy-plugin-conda.

The following works for me, and produces a working FreeCAD AppImage:

wget -c "https://raw.githubusercontent.com/TheAssassin/linuxdeploy-plugin-conda/master/linuxdeploy-plugin-conda.sh"

CONDA_PACKAGES=freecad CONDA_CHANNELS=freecad bash -ex ./linuxdeploy-plugin-conda.sh --appdir AppDir

( cd AppDir ; ln -s usr/bin/FreeCAD AppRun )

wget -c "https://github.com/linuxdeploy/linuxdeploy/releases/download/continuous/linuxdeploy-x86_64.AppImage"
chmod +x linuxdeploy-x86_64.AppImage
mkdir -p AppDir/usr/share/applications/
cat > AppDir/usr/share/applications/freecad.desktop <<\EOF

./FreeCAD-x86_64.AppImage # Works!

We are 98% there. But e.g., the version number should be carried over from Conda to the AppImage "automagically".

This is not ideal UX wise (not yet, at least), I will post an example how to do it with a single linuxdeploy call that uses the plugin via --plugin conda.

The plugin is just for bundling a conda environment and installing packages. Versioning is out of scope. All it does is bundle user-specified packages into a conda environment in a reproducible and comprehensible way. It's minimalistic, and really good at what it does right now. That's the UNIX philosophy.

However, it could be done by a shell script called conda2appimage.sh at some point. I guess some call to AppDir/usr/conda/bin/conda ... will provide the information you're looking for. Add linuxdeploy and linuxdeploy-plugin-conda to the mix, and with just a few lines of bash you should be able to get what you're looking for.

Actually, instead of a separate conda2appimage command, we should make the existing pkg2appimage aware of Conda, using the existing yml files, but specifying Conda rather than deb ingredients.

[TheAssassin]

Sure, however you like it. Perhaps we should consider replacing all the functions.sh stuff which is not really maintained (copy_deps etc.) with linuxdeploy.

Could it be that this last comment belongs to another issue @TheAssassin?

[TheAssassin]

Yes, deleted it, will move it there. Thanks for the hint.
