Give an example for an application that uses setup.py

[probonopd]

Please give an example for an application that uses setup.py such as this one:

https://github.com/BasioMeusPuga/Lector

[TheAssassin]

They all use setup.py. What do you want to do? Install directly from git/GitHub? Install from a local clone?

For the latter use case, just use export PIP_REQUIREMENTS=".". Note that you have to cd there to make this work. You can also provide an absolute/relative path. If you encounter issues because setup.py assumes you're in the directory, you can use PIP_WORKDIR as a workaround, which instructs the plugin to cd to a directory before running pip.

I would like to make an AppImage for https://github.com/BasioMeusPuga/Lector from its git master using linuxdeploy-plugin-conda but I do not know how to do this. Can you provide an example please? I don't think that Lector is in PyPI (and hence, pip).

[TheAssassin]

pip != PyPI. You've already used it to install stuff from git directly. It's not limited to PyPI. I've already given an example how you could use the plugin in a build script, just put a (relative) path into PIP_REQUIREMENTS.

[probonopd]

OK, let me give it a try. Sorry for the noise

[TheAssassin]

Don't worry, this can be confusing. In the Python world, things are IMO a bit "more open" than elsewhere, easier/more flexible in their use. Can be confusing for people who aren't used to it.

Keep asking questions please -- they'll probably be the base for some docs, if I ever get to it.

The application has no requirements.txt file so I tried this:

export PIP_REQUIREMENTS="-e git+https://github.com/BasioMeusPuga/Lector#egg=Lector -c conda-forge pyqt -c conda-forge beautifulsoup4 -c conda-forge poppler"

But I am getting

[conda/stdout] installing: conda-4.5.12-py37_0 ...
[conda/stdout] installation finished.
[conda/stderr] Warning: 'conda-forge' already in 'channels' list, moving to the top
[conda/stderr] Could not open requirements file: [Errno 2] No such file or directory: 'conda-forge'
ERROR: Failed to run plugin: conda (exit code: 1) 

https://anaconda.org/conda-forge/pyqt gave me the idea that I might try -c conda-forge pyqt but apparently this was wrong?

[probonopd]

Possibly I need export CONDA_CHANNELS=??? CONDA_PACKAGES=???

[TheAssassin]

This -c <...> stuff is for the conda CLI.

Did you mean to install stuff using the conda package manager? You need to use the other variables for this. I think it's quite apparent that PIP_* isn't for conda.

Perhaps something like this?

export CONDA_CHANNELS="conda-forge"
export CONDA_PACKAGES="pyqt5"
export PIP_REQUIREMENTS="-e git+https://github.com/BasioMeusPuga/Lector#egg=Lector beautifulsoup4 poppler"

[probonopd]

What would I do if I wanted package A from conda-forge and package B from anaconda?

From the beginning I found the environment variables counter intuitive. Why not expand the https://github.com/AppImage/pkg2appimage/blob/master/YML.md format so that we could write something like:

ingredients:
  conda:
    - git:https://github.com/BasioMeusPuga/Lector
    - conda-forge:pyqt
    - conda-forge:beautifulsoup4
    - conda-forge:poppler

Something like this... just an idea... maybe we can even write a small wrapper around the existing tools?

[probonopd]

With export CONDA_PACKAGES="pyqt beautifulsoup4 poppler" I get

[conda/stderr] Warning: 'conda-forge' already in 'channels' list, moving to the top
[conda/stdout] failed
[conda/stderr] 
[conda/stderr] PackagesNotFoundError: The following packages are not available from current channels:
[conda/stderr] 
[conda/stderr]   - pyqt==beautifulsoup4=poppler
[conda/stderr] 

[probonopd]

Got it, needs to be export CONDA_PACKAGES="pyqt;beautifulsoup4;poppler"

[TheAssassin]

Sorry for that, the UI isn't too consistent yet. Conda wants stuff in one way, pip wants it the other way, ...

[probonopd]

This is what I have put together for now:

#! /bin/bash

sudo apt -y install git

export VERSION=$(wget -q "https://api.github.com/repos/BasioMeusPuga/Lector/commits?sha=master" -O - | grep sha | head -n 1 | cut -d '"' -f 4 | head -c 7
)

export APPNAME=lector
export PIP_REQUIREMENTS="-e git+https://github.com/BasioMeusPuga/Lector#egg=$APPNAME"
export CONDA_CHANNELS="conda-forge"
export CONDA_PACKAGES="pyqt;beautifulsoup4"  # Only use this if the package is in a Conda channel (e.g., conda-forge); can also be used for dependencies if the main application has no depends.txt

wget -c "https://github.com/linuxdeploy/linuxdeploy/releases/download/continuous/linuxdeploy-x86_64.AppImage"
wget -c "https://raw.githubusercontent.com/TheAssassin/linuxdeploy-plugin-conda/master/linuxdeploy-plugin-conda.sh"
chmod +x linuxdeploy-x86_64.AppImage linuxdeploy-plugin-conda.sh

rm -r AppDir || true

wget -c "https://github.com/BasioMeusPuga/Lector/raw/master/lector/resources/raw/lector.desktop"

cat > AppRun <<\EOF
#!/bin/bash
HERE="$(dirname "$(readlink -f "${0}")")"
exec "$HERE/usr/conda/bin/python" "$HERE/usr/conda/bin/lector" "$@"
EOF
chmod +x AppRun

wget -c "https://raw.githubusercontent.com/BasioMeusPuga/Lector/ed5bc0b2b9b92a506d4eb2144e349075caf3a8c0/lector/resources/raw/Lector.png" -O app.png
convert app.png -resize 512x512 $APPNAME.png

./linuxdeploy-x86_64.AppImage --appdir AppDir --plugin conda -i $APPNAME.png -d $(readlink -f "$APPNAME.desktop") --custom-apprun AppRun --output appimage

How can I make it use https://github.com/BasioMeusPuga/Lector/blob/master/lector/resources/raw/lector.desktop directly?

[TheAssassin]

Does it work, though?

[probonopd]

Still running because it downloads everything again

[probonopd]

"Works" as in "runs" :+1:

I can't seem to open EPUB 3.0 files from http://idpf.github.io/epub3-samples/30/samples.html with it but that may well be unrelated to the AppImage packaging.
