Suggestion to add indicator for location of error in script (convenience feature)

[tomasrei]

Hi!

When I work with scripts that are on the longer side (and perhaps take longer to execute), it would be really useful to have a sort of hyperlink in the Console to the location in the script where the script was interrupted.

In addition, or as an alternative, it could switch on a point at the line where it stopped (sort of how Breakpoints work in Rstudio now).

What I do now is copy parts of the code that produced the error and use ctrl+f to find my way back to the location of the error in the R-script.

Thanks!

Currently you will only get source locations for files that you have sourced, e.g. with the "play" button at the top right of the editor:

Then you should get clickable location info, for instance in this backtrace I can click on at lionel / Desktop / test.R:15:1

If you evaluate expression by expression, e.g. with ctrl/cmd + enter, you will not get such links unfortunately.

That is interesting, but will this show which line the error occurred on or simply the file? I'm suggesting that Positron should indicate the line, preferably with a hyperlink and line indicator in the left margin of the script.

The use-case is that I often ctrl+enter through a longer script only to find that I get an error way up in the script, and it's annoying that I have to either manually look for the culprit or ctrl+f parts of the code to find it. Yes, maybe a minor issue, but still! 😁

Thanks for the feedback @tomasrei!

Note that the grey text in Lionel's picture (e.g. lionel/Desktop/test.R:5:5) is clickable. That will jump your cursor to where the problem is, which in this case is line 5, column 5. There won't be an indicator next to the script, but the cursor will move. Does that help?

Yes! It helps. Maybe expand the feature to include ctrl+f if possible.... And ctrl+alt+b and so on...
