[Feature Request] Zero-based line numbers

[lonix1]

Please add support for zero-based line numbers (e.g. editor.zeroBasedLineNumbers: true), so the first line is 0.

A similar request was closed due to insufficient votes. Please reconsider for the new reason below.

When developing vscode extensions, we use various zero-based properties like selection.start.line, selection.end.line, etc. I turn on editor.lineNumbers to make it easier to see what's going on, BUT, lines start at 1 so I often make mistakes when debugging. It would be much easier if I could set lines to start at 0.

Please reconsider this because:

• you're currently working on a disassembly view
• NEW REASON: it's useful for extension authors - and you obviously want to encourage extension authoring

Thanks!

I don't think this would be good. Many vscode internals use one-relative line numbers. getLineContent, folding ranges, etc. Changing those places to use zero-relative numbers would break many existing extensions. And changing only the on-screen appearance of the numbers would then add a new point of confusion when debugging. Because the displayed numbers wouldn't match the numbers stored in internal constructs like ranges.

No that's not what I meant. I don't want the APIs to change, obviously - besides, they are already 0-based. I want to optionally display 0-based line numbers in the editor, just for me.

All the APIs are 0-based, so showing 0-based line numbers would assist debugging extensions. (And there are other use cases too, see above).

@lonix1 You could write an extension that renders the selection in 0-based coordinates in the status bar.

@alexdima LOL that's actually a really clever idea! 😄

What about 0-based line numbers in the editor - do you think that is possible as an extension?
