#Python hivemind:

Is there a way to get `ruff check` *not* to treat code guarded by `sys.platform` as unreachable if the check would fail on the platform running the lint?

I am looking at adding `ruff check` to a project in the wake of a `NameError` that slipped past, but it seems to be incapable of catching this problem if it is guarded behind a platform check.

(if you reply to this to tell me to run `ruff check` on both platforms, you will be ZOTted, I mean the question the way I asked it)

@glyph @mitsuhiko I can tell you that in #python on Libera.chat, we have had very mixed results. AFAIK, not one of those users has become a continuing part of that community, but the things that lead most reliably to these users getting the help that they want are:

1) Avoid criticism of the chatbots. No room for persuasion generally, and flamewar is likely.

2) Much more patience is required. Choose your questions carefully, "too many" questions will lead to withdrawal. The extreme case is a user who is consulting the chatbot and the community simultaneously.

It's impossible to draw general inferences from an environment as pathological as IRC, but I would say these two points apply equally well to interpersonal interactions I have had in the local user group.

The overall impression I am left with is that the tools themselves disincentivize participation in a community, and incentivize talking to other humans only for swapping tips about tools, or as a way to get someone to "just" produce source code that fixes the tool's errors.

If I were @standupmaths , there would be some Terrible Python Code parsing the output of dnsqr and doing line fitting to the TTL values; and an entire video on how to estimate from such data how many real machines under the covers serve up some seemingly single service on the Internet, and a second channel one on how people did that from the Netcraft uptime graphs that it used to present a couple of decades ago.

And then a clever viewer switching from parsing text from a pipe to some proper Python DNS client library and achieving a 6283% speedup.

“Fun” learning YAML properly?

Okay. So. I have to learn ANSI-Bell for $ork. Meh. But okay.

Pre-existing “fun”

Playbooks are written in YAML. I hate YAML and have always used yaml2jsn to convert it to JSON (if possible) when I had to touch it in the past, as somehow a subset¹² of JSON is a valid subset of YAML accepted² by YAML parsers.

① you’ll have to make sure you don’t emit some codepoints literally, and to format numbers in scientific notation a specific way, but that’s generally a good advice for JSON emitters
② except JSON strings have codepoints outside the Basic Multilingual Plane encoded as two UTF-16 surrogates in \u#### notation whereas YAML parsers require it to be unescaped four-octet UTF-8, which breaks many JSON parsers; I ran into that just this week, in fact, for my RSS to Fediverse gateways…

I personally find YAML unwritable, due to things like GitHub Actions’ example of…

on:
  push:
    branches:
      - main

… does not convert to…

{
  "on": {
    "push": {
      "branches": [
        "main"
      ]
    }
  }
}

… but to:

{
  "1": {
    "push": {
      "branches": [
        "main"
      ]
    }
  }
}

(GitHub accepts both syntacēs in workflow files in JSON.)

But let’s go back to the “self-explaining, obvious” YAML:

on:
  push:
    branches:
      - main

So, we’ve already established that “on” is 1 and that something like country: no isn’t Norway but 0 (and real existing people have fallen into this, yet there are strong recommendations to not quote strings in YAML documents like ANSI-Bell playbooks, and somehow nobody even documents how strings are to be escaped and when they need to be escaped).

But, riddle me this:

push:
<2 spaces>branches:

But:

branches:
<2 spaces><hyphen-minus and space>main

But:

options:
<no space><hyphen-minus and space>Ubuntu
<no space><hyphen-minus and space>macOS

(All examples from here.)

I find this totally obvious and self-explanatory and consistent, and I totally know when to use two spaces, or dash-plus-space, or both.</sarcasm>

But there is training material!

One of the books I’ve been provided (actual published training material with an ISBN each) just hand-waves it away, the other says:

The target section looks like the following code snippet:

  - hosts: webservers
    user: root

[…] As per the YAML syntax, the line must start with a dash. […]

So, basically, the hosts: line must start with a dashhyphen-minus? I think not.

The “Hands-on interactive lab and helpful resources” in the Red Hat “YAML essentials for Ansible” “learning path” is similarly deficient in even fundamentally basic explanation. 0/10, won’t recommend.

Fun with training material, continued

The hand-waving book links to http://www.yaml.org/start.html, so let’s read…

a getting started guide for YAML

… in my favourite webbrowser lynx:

                                                   Page not found · GitHub Pages
 
 
   File not found
 
   The  site  configured  at  this  address does not contain the requested
   file.
 
   If  this is your site, make sure that the filename case matches the URL
   as well as any file permissions.
   For root URLs (like http://example.com/) you must provide an index.html
   file.

   Pages.

… oooookay?

But surely yaml.org has more material? *looks* … well, it has links to the specs and implementations. All very useful, but not right now for a hopefully structured introduction that explains the hows and ideally also the whys.

Let’s follow the *New* link in which they announce the 1.2.2 spec… a blogpost. Okay. It has a title bar (brown background in Firefox) with a promising link:

YAML Documentation
     __________________________________________________________________
 
   YAML documentation is on the way!
 
#content

This 80×24 screenshot is literally the entirety of the official #YAML documentation.

Well, colour me impressed.

Wait, no.

Fuck that shit.

Wait. This is for $dayjob. $customer also edits playbooks. I’m sure they’ll be delighted if I run things through yaml2jsn and commit the result as #JSON.

Also, see footnote 2 above.

Fuuuuck I’m SOL.

So. Do I honestly have to wade through the spec to learn this?

(Not that this is new. When I first learnt Python in 2008, I had to look at the C-language source code of the #Python interpreter to figure out things missing from the documentation. Which brings us back full circle to #ansible, the culprit of bringing this entire shitshow to my attention. I’m a programmer, not a DevCloudOp or something.)
