Bat: Different color scheme in Alacritty

[dikiaap]

The color scheme works well in LXTerminal, but in Alacritty where the color scheme becomes slightly reduced.

Default:

In the default theme, the orange and magenta color is also reduced.

Thank you for the feedback.

I can not reproduce this. I am using alacritty 0.1.0 with this configuration.

Can you please post your alacritty config and check whether $COLORTERM is set to truecolor?

[sharkdp]

Actually, it seems that alacritty does not set the $COLORTERM variable. I accidentally started alacritty from terminator, which is why I had $COLORTERM set.

Could you try to export COLORTERM=truecolor and see if that fixes the colors?

In any case, something seems wrong with your alacritty configuration. There shouldn't be any background colors. Even in 8bit mode (no truecolor support) with interpolated colors, it looks fine for me (although differences are noticeable).

@sharkdp Yes, It's not set in here. I just tried exporting that and it works now. Thank you!

I'm going to reopen this because there should probably be another way to detect truecolor support for a given terminal.

If not, we should at least document the behavior concerning the COLORTERM environment variable.

I have added a "Troubleshooting" section to bats README and I have opened a ticket for alacritty to discuss the support for the COLORTERM variable (corresponding PR).

I don't think there is anything more we can do here as there doesn't seem to be a way to detect whether or not bat is running inside alacritty.

The upstream ticket has been solved.

Until the fix has been released, you can also set COLORTERM in your alacritty.yml:

env:
  # ...
  COLORTERM: truecolor

which is probably better than exporting it in your shells init file, because that would affect other terminals as well.
