Syntax error indicators missing in editor (red X/markers like RStudio)?

[jhelvy]

Hi Positron team,

I'm exploring Positron and noticed that syntax errors don't appear to have visual indicators in the editor gutter.

In RStudio, when there's a syntax error, a red "X" appears on the affected line, making it easy to spot issues at a glance. In Positron, the same syntax error doesn't show any visual marker.

Example:

Is something like this a planned feature? Or perhaps is it already supported by I'm just missing the setting?

Thanks for your work on Positron, it's an absolute dream for an IDE!

The way that Positron indicates a syntax error is with a squiggle and a note in the "Problems" pane:

There are some extensions like this one that you can install that make the syntax errors even more prominent, if you like.

I think the y 7 example here is interesting, though, because Positron does not currently identify that as a syntax error. Let me check in with a few folks to see if we should do so!

I opened Syntax like `y 7` does not generated a syntax error · Issue #194 · r-lib/tree-sitter-r · GitHub for us to get that particular syntax error handled better, but if you want indications in the gutter, you'll want to try out that extension. Thanks for the report!

Cool, I figured there was something already there. I still don't see a Problems pane though, is there a setting to turn it on?

[julia]

By default, it is in the bottom panel, between the terminal and output:

You can also focus on it by running Problems: Focus on Problems View from the command palette.
