Feature: Linux Support

[Rucadi]

I think that supporting Linux should be straight-forward, but I Don't know if you have any reason not to support it.
Probably an AppImage could be created for convenience.

In order to test the Linux version, I created this Dockerfile:

FROM fischerscode/flutter
USER root
ENV DEBIAN_FRONTEND=noninteractive
RUN apt update && apt install -y ninja-build clang pkg-config libunwind-dev libgtk-3-dev libwebkit2gtk-4.0-dev libssl-dev libsecret-1-dev xpra

USER flutter
RUN git clone --depth=1 -b linux https://github.com/Rucadi/FEhViewer
WORKDIR  /home/flutter/FEhViewer
RUN mv lib/config/config.dart.sample lib/config/config.dart
RUN flutter build linux --release

CMD xpra start :100 --bind-tcp=0.0.0.0:8888 --daemon=no --start-child=/home/flutter/FEhViewer/build/linux/x64/release/bundle/fehviewer --start-new-commands=no --exit-with-children  --quality=100 \
  --encodings=vp9 \
  --min-quality=100

That can be used via:

docker build . -t fapp
docker run -p 8888:8888 --rm fapp

Which exposes a page at localhost:8888 with the application running.

(Check the bottom right for the window, it likes to hide a little)

Thank you very much, could you consider adding support in GitHub Action build scripts as well?

I created a test branch, added the build script for linux, and it doesn't seem to be too much of a problem.

You can test if Artifacts works
But there seems to be some work to be done to build it as an AppImage!

That was fast!
I was just working also on it hahaha

I was in the appimage generation part, for the moment I had something like this (WIP, probably will not work yet, missing icon and desktop)

` - name: Install appimagetool
run: wget -c https://github.com/AppImage/AppImageKit/releases/download/continuous/appimagetool-x86_64.AppImage && chmod +x appimagetool-x86_64.AppImage

  - name: Generate AppImage
    run: |
      mkdir FEhViewer.AppDir
      cp -r build/linux/x64/release/bundle/ FEhViewer.AppDir
      echo '
            #!/bin/sh
            cd "\$(dirname "\$0")"
            exec ./fehviewer
            '> FEhViewer.AppDir/AppRun
       chmod a+x FEhViewer.AppDir/AppRun
      ./appimagetool-x86_64.AppImage FEhViewer.AppDir

`

I have no experience with gitlab ci actions, I Was using "act" to build the job, are you just letting github build it or do you have some kind of setup to do it locally?

[Rucadi]

I created an script called build_appimage.sh in my branch, it generates an AppImage, (but first you have to compile with release).

I have this appimage generated on my branches, and now the fork at Rucadi:linux has the latest changes done:
https://github.com/Rucadi/FEhViewer/suites/17922301180/artifacts/1029748318

I don't know if it will work as-is or if more things need to be taken into account.
The icon is just a placeholder.

Confirmed woring on https://www.onworks.net/ where I created a VM, downloaded the appimage and it just worked.

The PoC is done wit this, try to take a look when you have time at the branch, and propose an adaptation (or adapt) the scripts freely :)

[Rucadi]

I created a NIX Package so it can be installed on nixos or other distros with nixpkgs installed,
for the moment it is here:
https://github.com/Rucadi/nixpkgs-fehviewer

The implementation can be seen here:

{ lib
, flutter
, fetchFromGitHub
, makeDesktopItem
, pkg-config
}:

flutter.buildFlutterApplication rec {
  pname = "fehviwer";
  version = "testing_linux";

  #pubspecLockFile = ./pubspec.lock;
  depsListFile = ./deps.json;
  vendorHash = "sha256-QqR1isHtQqGDhxkzuy5hm7Vem9iI1qBfK5GZLt/h03U=";

  src = fetchFromGitHub {
    owner = "Rucadi";
    repo = "FEhViewer";
    rev = "master";
    hash = "sha256-Sx7JkzgH/8NRpG5h/5aeqsZa4Jqd3M7vy4rlAQ+xHVA=";
  };

  prePatch = ''
    mv lib/config/config.dart.sample lib/config/config.dart 
  '';

  postInstall = ''
    rm -rf $out/bin/*
    makeWrapper $out/app/fehviewer $out/bin/fehviewer  \
            --prefix LD_LIBRARY_PATH : $out/app/lib
  '';


desktopItem = makeDesktopItem {
    name = "FEhViewer";
    exec = "@out@/bin/fehviewer";
    #icon = "fehviewer";
    desktopName = "FEhViewer";
    genericName = "View E-Hentai and ExHentai libraries!";
    categories = [ "Adult" "Viewer" "Art" ];
  };

  meta = with lib; {
    description = "View E-Hentai and ExHentai libraries!";
    homepage = "https://github.com/3003h/FEhViewer";
    license =  "Apache 2.0";
    maintainers = with maintainers; [  ];
    platforms = platforms.linux;
  };
}

Once this is mainstream, is it fine by you if I create a MR to nixpkgs to include it on their repositories?
Probably this also compiles on ARM64 by default for linux.

That would mean that it can be installed in nixos/any linux with nix as easy as doing:

nix-shell -p fehviewer

However, I Don't know if your analytics can be integrated there.

Of course, no problem.
