Closes: #52567

Not completely ready. I have to double check some things because there are reported errors.

I'm opening the PR to ask a question:
For now, I put the entire config in one file. I would like to split it into multiple files to make it more readable but I'm not sure what approach to take. My current idea is to create a new folder, probably somewhere in tools.

To me, the most obvious choice would be to have them in each directory (e.g. lib/eslint.config.mjs, test/eslint.config.mjs)

I think this would be confusing, because they would not be ESLint config files, just partials for the real config, and it would make people think they work like the old config system.

Maybe we can use an non-confusing name, lib/eslint.partialconfig.mjs or whatnot.

SGTM. I'll wait a few days to see if there are other suggestions.

Done! I went with eslint.config_partial.mjs so I could colocate it with eslint.config_utils.mjs in tools.

Looks like lib/eslint.config_partial.mjs is picked up by js2c.cc. Not sure what's the best way to ignore it. /cc @joyeecheung

@targos Can we also enable indentation rule for "Makefile" file?

You can hard-code to exclude it from the JS2C like this:

diff --git a/tools/js2c.cc b/tools/js2c.cc

+                      mjs_it->second.end(),

(Or make it more flexible as another vector to ignore, or make it an argument, or prefix it with a dot and ignore all files beginning with a dot in SearchFiles, if you want)

If you want to ignore all files beginning with a dot, probably just do this (not sure if we have any files starting with a dot that we actually want to include in the binary, I am guessing we don't):

@anonrig Maybe, but it doesn't seem related to what I'm doing here?

Note that .\vcbuild.bat lint-js is already broken on Windows on the main branch because of this file: https://github.com/nodejs/node/blob/main/tools/node_modules/eslint/node_modules/eslint

It might make sense to wait for #53023 to land and get rid of this.
