Code actions to disable shellcheck rules for lines or entire files

[polyzen]

What is the problem this feature will solve?

Currently it seems there are only code actions to apply fixes when available. Code actions to disable the rules (using comments) would also be appreciated.

What is the feature you are proposing to solve the problem?

Additional code actions, eg. null-ls offers:

Disable ShellCheck rule 2059 for the entire file
Disable ShellCheck rule 2059 for this line

What alternatives have you considered?

+1 for this idea 💡

@polyzen i’m not sure what editor you use, but as a stopgap, i’ve written a little neovim lua command to insert a shellcheck disable statement based on the current line’s lsp diagnostics into your buffer:

hope this helps for now.

@xero I think I found a better solution for neovim: #999 (comment)

Hello there!

I have made a first draft to try to address this issue:
ThomasFaivre@d0b80ff
It does stuff (tested in neovim+LazyVim), but it is not finished for several reasons:

• handle indentation
• handle existing disable lines
• make tests
• Stuff I'm missing

I wanted to get some inputs before continuing.
And I have some questions. I am very new to Typescript (like, this is the second time I am touching javascript related code :D ), so I apologize if my questions are strange.

• What would be the best way to get indentation? I'm assuming it would have something to do with the TextDocument, but how to get a given line? Kind of the same question to detect an existing disabling line.
• Should I keep using getTextEdit* methods? Since data does not come from a ShellCheckReplacement object. I could use a TextEdit object directly. For instance, insertionPoint and precedence are not used.
• codeActions variable could directly be an array, instead of a mapping of array with id as keys that we just flatten after creating it. But I'm afraid of breaking Fix ShellCheck code actions not working on some clients #700.
• I have no idea how the node engine works, so there might be some optimization/performance concerns to deal with.

As for enhancement, this patch would open the possibility of adding a disabling of the rule at the scope level (function/if/while...) which does not exist in nvimtools/none-ls.nvim.

Also, tell me if you want a Pull Request in order to start a proper review.

Hope this will help!
