Support Pascal Case for L030

Search before asking

• I searched the issues and found no similar issues.

Description

It often makes sense to have function names as PascalCase, for example DateAdd or IsNull. Unfortunately, L030 only offers upper, lower and capitalize, which are all less than ideal for these cases.

Use case

I would like my function names to be easily readable. For names that consist of multiple words, PascalCase makes the most sense.

Dialect

At least T-SQL, but probably relevant for all dialects.

Are you willing to work on and submit a PR to address the issue?

• Yes I am willing to submit a PR!

Can you be clear what you mean by PascalCase here?

I presume you mean:

• Starts with a capital letter? Or happy with pascalCase too?
• Has at least one lowercase letter? Or is EXAMPLE still valid PascalCase?
• Depending on above should it end in a lower case?
• For Autofix the best we could do is initial capital letter (e.g. examplefunction or EXAMPLEFUNCTION would both be autofixed to Examplefunction rather than ExampleFunction which is probably the right answer but impossible to really get a system to understand)? Or should PascalCase not be Autofix compatible so always will require manual intervention?
• Should it convert snake case? E.g. pascal_case is converted to PascalCase?

Depending on answer to those (particularly the second one) it might be best to just turn off rule L030 rather than add to it.

As L014 already has PascalCase, I thought it could and should use the same logic 🙂

Oh that makes it easier: #2739

Is a breaking change though as requires all users of this rule to update their config 😞
But I think a good change.

That was fast, thank you!

Luckily was simple once you pointed me in the right direction! 😁
