Arch Linux User Repository

Currently there's an error when starting WALC which breaks WhatsApp integration. A quick workaround is to navigate to /opt/WALC and run sudo mkdir -m 755 .wwebjs_cache && sudo chmod 755 -R ./.wwebjs_cache

The problem is that it needs to be run at every initiation of WALC. I'm not sure on how to approach the issue, and don't have the time to go through the debugging process at the moment. But I'm open to suggestions.

You can install the walc-appimage package (not maintained by me) instead, that's working as intended.

So store the content I sent you in the previous commit

I think you meant comment

Hey @YoungFellow I am not sure if I can create pull requests on AUR. I sent you a so-called patch file. This can be applied with git apply <patchfile>. https://git-scm.com/docs/git-apply

So store the content I sent you in the previous commit in a file like patch-build.patch and apply it in the git repo of your AUR package with git apply patch-build.patch

Hello @HaCk0, thank you for sharing this with me. I thought I already tried this, but apparently not. I am testing it out now.

But excuse my ignorance, where can I find this patch of yours, and is it like a GitHub PR? I've never seen this before. I would rather merge it than just enter it manually myself. Thanks.

Hey Here is a git patch to fix the issues with the current version:

Would be nice if you could apply it to the package

Yes @perro, the script is throwing an error at the moment. I'm trying to debug the errors. Please use the AppImage for now. Sorry for the inconvenience

I get an error when launching the application, because the file /opt/whatsapp-web-electron.js doesn't exist.

Thanks a lot for the support @opensorcerer!
Regarding namcap, this is what I get:

❯ namcap -i PKGBUILD           
PKGBUILD (walc) I: Missing Contributor tag

So I adjusted the PKGBUILD according to your suggestions:
1. arch=('x86_64') This is correct I presume...as arch officially supports only 64 bit?
2. license=('GPL3')
3. depends=('nodejs-lts-gallium' 'npm' 'gtk3' 'alsa-lib' 'nss')

Do you think I should push walc-0.2.2-3 though?
Or shall I wait until the next version is out?

Thanks again!

PS: I'll see what I can do regarding the npm logs, I might ask the project maintainer, but for the time being, I'm trying to get my pentesting certification over with, so I'll be a bit short on "research" time.

Excellent work on your first PKGBUILD!

One more thing: When you create your package, make sure you test both the PKGBUILD and the resulting package with namcap. namcap notifies you of common mistakes in packaging. There are error, warning and info levels of mistakes of which the errors are most important to fix.

Current walc-0.2.2-2 has a number of these errors you should turn your attention to:

1. You specify arch='any', but include executable files built for a specific arch. Note that this 'any' does not mean "it can be built on any arch" but "when built, it can run on any arch". Naturally, it's best suited for things you don't really build, like shell scripts. See wiki entry.
2. There is no "GPL-3" license. The proper name is GPL3. See the contents of /usr/share/licenses/common for other acceptable contents.
3. You use npm start to launch walc, which in turn launches electron, but electron is missing dependencies: gtk3, alsa-lib and nss. There is a chance walc won't even launch on a fresh Arch Linux install.

There is rather long output on the bundled node-modules and shared libraries. I wonder if it's possible to reduce their existence there so far as to try and use the system-provided ones. A long list of warnings suggest they're not used, anyway. But that's for another time and if you've got the time. :)

Thank you for the package, and packaging.

Hey @opensorcerer, thank you for pointing that out to me, as this is my first PKGBUILD I just wrote everything into the package() function as if it were a bash script.
As per your advice, I split the process into the correct functions, and used gendesk for creating the desktop entry.
Thanks a lot.
