find_program already checks if the program was found. No need to check yourself:

Nit: I'd put this macro in plugin/emacs/CMakeLists.txt instead of here. This macro is tightly coupled to quicklintjs-pkg.el, so I think the two belong next to each other.

Why add CMAKE_CACHEFILE_DIR? What files are in the build dir that we need to expose to Emacs?

that's the output directory for the package, otherwise Emacs would make it somewhere on its defaults, (probably ~/.emacs.d/elpa), i used the CMAKE_CACHEFILE_DIR because i assume cmake calls ${QUICK_LINT_JS_EMACS} with current directory being the same from it was invoked from, so the root of build directory would have been filled with emacs package folders instead of ${BUILD_DIR}/plugins/emacs. I cloud've made this from emacs by appending plugins/emacs to cwd, or you have something else in mind?

Oh. It looked like an input directory to me.

${CMAKE_CURRENT_BINARY_DIR} might be better.

I think specifying cwd explicitly is what we should do:

  add_custom_command(

      -Q -batch
      -l package --eval "(package-initialize)"

      ...
    WORKING_DIRECTORY "${CMAKE_CURRENT_BINARY_DIR}"

Minor: This command is pretty noisy during building. Can we silence the output unless there is an error or warning?

Why do we need five separate packages? Could we make just one package? Seems simpler to make one package IMO.

Could we make just one package?

Yes, to use what emacs calls "multi-file" packages, it would require tar available while building the packages tho, i didn't use it here because i imagine that's unlikely to tar be available on a Windows machine, what you think? i'm fine with both ways.

CMake provides a tool to create tar archives: https://cmake.org/cmake/help/v3.21/manual/cmake.1.html#run-a-command-line-tool

$ cmake -E tar czf src.tar.gz src
$ file src.tar.gz

@strager i made the change to use a tar archive as a single package, besides that it feel clunky, it's discouraged by package archives, do you think the last "problem" in this list applies here? i do think. https://github.com/melpa/melpa/blob/5d49574/CONTRIBUTING.org#fixing-typical-problems

it's discouraged by package archives

Having multiple .el files in a package is discouraged? O_o I'm unsure if that's what the documentation actually says.

do you think the last "problem" in this list applies here? i do think. https://github.com/melpa/melpa/blob/5d49574/CONTRIBUTING.org#fixing-typical-problems

It says:

MELPA only looks at the main .el file (or -pkg.el file, if provided, though we discourage that).

What does it mean to "look at" an .el file?

What does it mean to "look at" an .el file?

In short, an .el file can be package on its own, its format something along the lines:

;;; <name>.el ---
;;; <headers>

<code>

;;; <name>.el ends here

so when it says "look at" an .el file, is an .el file which is in this package format, when a package has multiple .el files, this format is not used, instead there should be a tar archive that contains all .el files along with a magic <name>-pkg.el, which must call (define-package ...args).

[a tar archive is] discouraged by package archives, do you think the last "problem" in this list applies here? i do think. https://github.com/melpa/melpa/blob/5d49574/CONTRIBUTING.org#fixing-typical-problems

I think we should do one of two things:

  • merge all of our .el files into one .el file
  • create a tar, even though MELPA docs say "we discourage that"

I'm happy with the tar if it's already implemented and if it makes developing the plugin easier for us.

Did you intentionally rewrite this code in this commit? This change seems unrelated to unifying settings. (The change looks fine, though.)
