Use Eask for CI

[jcs090218]

This patch does the following:

In .github/workflow/test.yml

• Use jcs090218/setup-emacs instead of purcell/setup-emacs
  • Add retry capability to prevent failure on Emacs' installation
  • Support windows
• Add setup-node (16)
• Remove setup-cask (replace with setup-eask)
• Add test for Emacs 28.1
• Add tests on Windows and macOS

In Makefile

• Replace Emacs command-line arguments emacs --batch ... with just eask <command>
• Remove ELS variable, manage with Eask-file (use command eask files to list all package files)
• Add make checkdoc and make lint but currently disabled, see error log here.
• Add make build to test packaging and installing.
• Replace make xxx-autoloads with just eask autoloads

Others

• Eask-file added

---

This is totally optional, I think this would make CI a lot easier.

Thanks for the great work! cask has been a pain in the ass for quite some time. Did you already announce the package on reddit ?

[jcs090218]

Thanks! :)

No, I haven't announced the package anywhere. This isn't a standard package so it will not be published to MELPA like Cask and Eldev. :(

But feel free to announce the tool anywhere if you like it! 😄

I just think there are many package maintainers who would be thankful to have a replacement for cask. But people will start using it for their packages when they see it's used for popular packages like lsp-mode.

That's basically the goal for Eask; maybe an alternative or replacement to Cask. 😁
