Operating System:Arch

Issue:

Sometime it takes "forever" to get a new line after pressing <enter> at the end of the line. Without

    oni.input.unbind("<enter>")
    oni.input.bind(["<tab>"], "contextMenu.select");

I don't even get one, I press enter and it just removes my comma in the example below.

Expected behavior:
Slow as hell!

Actual behavior:
Fast as heaven :grin:

Steps to reproduce:

CurrencyCard.propTypes = {
    currencyId: PropTypes.string.isRequired,
    first: PropTypes
};

type .array,<enter>, where "array" is a property of PropTypes and type it fast enough the completion popup doesn't come up. When the popup come up, it is still slow but a little bit faster.

Performance analysis with 246ms block selected which should not be there.

Could this be related to https://github.com/onivim/oni/issues/2370?

It might also be worth updating to the latest release, just so we know that isn't the issue.

@hoschi Oni for Arch has been updated to 0.3.6, can you check if this still persists?

[hoschi]

@CrossR @badosu I tried 0.3.6 and master. Also suggestions from linked issue and disabled animation and type prediction. Problem still persists.

Thanks for reporting the issue @hoschi (and testing on the latest version)!

A performance profile would be really helpful (like the one attached to #2370) - can help us narrow down where the bottleneck is 💯

In addition, which filetype are you seeing this? Is it typescript?

[hoschi]

@bryphe it is JavaScript and here is the profile :wink:
Profile is with version 0.3.6, just say it if you want master instead.
