enquirer VS coreutils

Although I'm happy there is a way to bundle Node.js apps with support for pnpm, and for a modern-ish version of Node.js, it's somewhat slow in my experience to build locally. Interactivity doesn't have the greatest ecosystem there, especially with TypeScript. Best library I've found is Enquirer.

{ "name": "@jonschlinkert/omit-deep", "description": "Recursively omit specified keys from an object", "tags": ["object", "deep", "remove", "omit"], "version": "0.3.0", "author": "Jon Schlinkert (https://github.com/jonschlinkert)", "repository": "jonschlinkert/omit-deep", "bugs": "https://github.com/jonschlinkert/omit-deep/issues", "license": "MIT" }

In case you need to ask for user input, optionally you can use a prompt file. This is very useful to customize the output of the generator. Prompts are defined using a library named Enquirer.

> I don't fully understand why packages like this are so popular.

It actually works like this: Author X develops `iseven`, `isodd`, etc. No one really downloads such packages. Author X then develops `importantPackage` which does do something useful developers out here download. Now `iseven`, `isodd` are downloaded alongside `importantPackage`.

My point is, we should recognize certain NPM authors as toxic, but I guess "freedom of speech/code" stops us from doing so. Example of such an author: https://github.com/jonschlinkert/

something like enquirer

You're thinking of Jon Schlinkert, publisher of 1435 packages on npm.

It's insanely funny to me that these packages exist while one of his bigger projects (https://github.com/enquirer/enquirer) lists the following reason under "why use it":

> Lightweight - Only one dependency, the excellent ansi-colors by Brian Woodward.

It's written by this guy, who shits out micro libraries by the hundreds. He moved the project to another user under the pretense that he was learning to program back then, but a lot of his stuff is similarly inconsequential micro libraries.

A summary of other changes just released in GNU coreutils 9.5 are:

* mv accepts --exchange to swap files

> some are simple like yes(1)

Not that simple: https://github.com/coreutils/coreutils/blob/master/src/yes.c

The -S / --split-string option[1] of /usr/bin/env is a relatively recent addition to GNU Coreutils. It's available starting from GNU Coreutils 8.30[2], released on 2018-07-01.

Beware of portability: it relies on a non-standard behavior from some operating systems. It only works for OS's that treat all the text after the first space as argument(s) to the shebanged executable; rather than just treating the whole string as an executable path (that can happen to contain spaces).

Fortunately this non-standard behavior is more the norm than the exception: it works at least on modern GNU/Linux, BSDs, and macOS.

> building a cat from scratch

Here is the source code of the OpenBSD implementation of cat:

> https://github.com/openbsd/src/blob/master/bin/cat/cat.c

and here of the GNU coreutils implementation:

> https://github.com/coreutils/coreutils/blob/master/src/cat.c

Thus: I don't think building a cat from scratch or creating a tutorial about that topic is particularly hard (even though the HN audience would likely be interested in it). :-)

the yes command, writing to /dev/null, is making IO calls, which interfere with predictable scheduling.

If you look at the source code for yes, https://github.com/coreutils/coreutils/blob/master/src/yes.c

it builds a buffer of output and then writes that in a for loop

  while (full_write (STDOUT_FILENO, buf, bufused) == bufused)

Looking at the source of nohup, if the execvp() of the child happens then it _must_ have already done the signal (SIGHUP, SIG_IGN) so - WTF?

This got me wondering so I went and looked and it seems like lo and behold there was actually a commit to the GNU ls source just 2 weeks ago.

https://github.com/coreutils/coreutils/blob/master/src/ls.c

"maint: prefer char32_t to wchar_t"

even an empty file? Yes. so now it was a file with a copyright disclaimer and nothing else. And the koan-like question comes to mind is "Can you copyright nothing?" well AT&T sure tried.

Then somebody said our programs should be well defined and not depend on a fluke of unix, which at this point was probable a good idea. so it became "exit 0"

Then somebody said we should write our system utilities in C instead of shell so it runs faster. openbsd still has a good example of how this would look.

At some point gnu bureaucracy got involved and said all programs must support the '-h' flag. so that got added, then they said all programs must support locale so that got added. now days gnu true is an astonishing 80 lines long.

> Yes, ls is maintained. Although, maintained is a very strong word. It exists.

Why would it be a strong word? Here it is, in src/ls.c: https://github.com/coreutils/coreutils

It is then packaged by tens of operating system distributions, who themselves maintain extra patchsets, some of which are then upstreamed.

It is installed and used on millions (billions?) of devices, for 3 decades.

It's a very reliable and trusty "sharp stick of metal" :)
