Lines starting from 0

Hi,

would it be possible to add an option to start lines from 0 instead of 1 ?

I am working on a chip emulator in assembly which has offsets into tags starting from 0.

Thanks :)

@markusmoenig Sorry, but I'm not sure I understand the feature that you need. Do you need the first line to have a line number, which is labeled "0", or do you need the internal line count (in the line map) to start at 0?

Changing the line number that is printed to the left of each line would instead require a change, but a very simple one.

Internally, the line map already starts from 0 and the API allows to use both 0-based or 1-based line numbers when creating a position value.

I would need the line numbers to count up from 0. Is that already in the API ? Did not see it.

Thanks

@mchakravarty While I have your attention, how do I get the current CURSOR position when it changes ? I seem to only be able to access selections and scroll positions ?

I would need to get the current line position to show help information about the assembly instruction on that line.

Thanks

No, that's not yet supported, but easy to add. I'll try to have a look at it this or next week. (Or feel free to have a go yourself and send a PR.)

You can do this with the setInfo argument, which I added recently — see

CodeEditorView/Sources/CodeEditorView/CodeEditor.swift

Line 209 in 31c87f7

/// - setInfo: Callback that lets the code editor update the context about informational aspects of the current

(The reason that this is not included in the position information is because you can use position also to set the selection and scroll position. Having the selection —with the insertion point as a special case— and line/column position in here would allow a lot of inconsistent values. In contrast, setInfo is unidirectional, you can observe it, but you can't set it.)
