I came here from reddit. How do I make the rounded corners in the statusline? I'm using a nerd font version of Iosevka if that helps.

I use the latest standard version of Iosevka. Maybe the Nerdfont does not have the rounded blocks.

I think I managed to do it, basically I use nvim-qt so if empty($DISPLAY) seems to be true for me always, so I removed the if from my script.

Good finding.

I came from Reddit as well. I am a new VIM user. Can you please tell me how to use this ? I am using NVIM and I just pasted all the above in my init.vim , but there are bunch of errors happening as soon as my launch my instance of Neovim. Please suggest.

Thanks

Without knowing the errors I just could guess badly. Please give more details.

Install ALE and GitGutter even if you dont use them. This script depends on them. GitGutter is a must but ALE for my workflow isn't. I was thinking of editing the script further to be independent of ale but I dont know much vimscript. Maybe I might make one later

Thank you for the input. Hopefully it will work now. If not, please keep hinting what is wrong.

Just please keep in mind that this is not an official "package" I maintain.

Thanks a lot for this! It inspired me to write my own statusline.

Where did you get the rounded circle unicodes, and do you have the exact codes?

I found a pair, but they were smaller. I could use a pair that is a little bit smaller, but i'm guessing that isn't possible

Nice to hear that it inspires you for an own statusline. :)

The characters are in the line 37 and line 38. The unicodes are U+E0B6 for left and U+E0B4 for right. Both characters are in the private use area of Iosevka.

Cheers!
