+      group = ['./', '../'];
+    } else if (completeOn === '..') {
+      group = ['../'];
+    } else if (/^\.\.?\//.test(completeOn)) {


Question: isn't there a difference between what is available for ./* and ../*?

In this context no, there isn't, both ./ and ../ just mean that we should start collecting completions starting from process.cwd(). The whole magic with path.resolve() is happening in the loop below.

-    var paths = module.paths.concat(require('module').globalPaths);
+    let paths = [];
+    if (completeOn === '.') {
+      group = ['./', '../'];


Could this include all directories in the current working directory? Bash does this for example with executables.

Also this should work with files starting with ., right?

All directories in the current working directory will be autocompleted if user types ./ instead of just .. AFAICT, that's how bash works too, it just completes . to ./ first unconditionally.

Right, I forgot about them. Thanks.

@TimothyGu wait, no, it shouldn't :) One can only require them as ./.filename, and they will be completed on require('./.

Ah okay.

Oh right. Thanks for clarifying :)

This doesn’t land cleanly on 8.x; if you can, please follow the guide and raise a backport PR, if you don’t think it’s worth it let me know and add the dont-land-on label.
