Thank you for taking the time to improve Flycheck.

Checklist

  • I have checked existing issues for potential duplicates before creating this one.

Feature description

I would love to be able to make flycheck not display error information when cursor comes upon the error in the buffer.
Motivation is that I am currently using flycheck-inline and while I love it, I find the behaviour where the error appears whevener I go over the affected piece of code with my cursor, too aggressive, as it the rest of my code jump up and down even when I don't care about the error message. Instead, I would love to be able to display the error under cursor manually, when I need it.

I figured out that probably I can show error manually with flycheck-display-error-at-point, but I failed to find a way to disable automatic showing of errors.

Ideal behaviour would be that I have to manually trigger showing of error under the cursor, but that it dissapears on its own if error is fixed/removed or if I move my cursor away.
For example, this is how a tooltip in lsp-ui behaves like, exactly like this.

I imagine this could be some var we can toggle, and that would provide this behaviour in such case.

Describe alternatives you've considered

I have tried setting flycheck-display-errors-delay to nil or 0 or negative value but that just removes any delay.
I found the issue #1332 that was asking for this same feature, but it was closed, and solutions from it work only half way (at least when I tried them). It had a PR open, but it was taking long time to finish and was abandoned at the end.

Thanks for any help!

Another option is sideline-flycheck.

Another option is sideline-flycheck.

Thanks for mentioning! I am aware of sideline as an option, but I find it problematic when needing to display multi-line errors, and we get a lot of those in Haskell (where I do a lot of my development), they are not aligned well in the sideline and are quite hard to read.

But 7AD7 in general, I don't want something constantly jumping out as I move around the buffer, be it in the sideline or popup or minibuffer, I would leave instead to be able to have that info displayed on demand.

It was recently resolved by introducing a new feature, sideline-truncate. Would you be willing to give that a try?
