Enforce error message style

I want to say: This is a failure, you should use a blimp

Which of the following should it be:

• This is a failure, you should use a blimp
• This is a failure. You should use a blimp
• This is a failure. You should use a blimp.

Keep in mind that if we go for the last one, which looks the best, it becomes inconsistent with one sentence error messages, which usually don't end in a dot.

#1 for one sentence error message and #3 for multiple sentences. I don't mind them being inconsistent tbh and it's usually what I do anyway.

@jfmengels @jamestalmage @SamVerschueren Thoughts?

Think I like 1 the most.

[sindresorhus]

@SamVerschueren It's a bad example though. What if you have 3 sentences and comma isn't valid to separate them.

Not a big fan of this rule. I understand the frustration, but this will be hard to treat well, and will only work well when writing errors in English. Sounds to me like a rule that will be disabled more often than the others.

Just wondering why this actually is the case? Why can't we just end all the messages with a dot?

[sindresorhus]

@SamVerschueren It's common convention to not end error messages in a dot, but it becomes weird when you have multiple sentences.

@jfmengels Why will it be hard? And why do you think it will only work for English? It will work for any language that ends sentences with a ..
