does ====== ligature in Fira Code rendered correctly?

technically they are rendered in same way

[Ordeeper]

Ye, it's rendered correctly

Fira Code

Maple Mono

[subframe7536]

have no idea how to deal with it 🥲

[Ordeeper]

When I have time, I’ll take a look

[Cyberczy]

Not only # has this problem, but there is also this problem in btop

[subframe7536]

can you test if V7-beta2 fix this issue?

[Cyberczy]

can you test if V7-beta2 fix this issue?

I cant use kitty +list-fonts --psnames | grep Maple to find MapleMono-VF, But can be found using fc-list | grep MapleMono-VF

[subframe7536]

Oh, weird things. I have little experience about kitty.

Maybe some issues with width or monospace flags

[subframe7536]

updated vf.zip, it should be correctly recognized.

can you also test if italic lll with "calt" correctly rendered?

[Cyberczy]

I'm here to test now lol

[Cyberczy]

Seems like there's still a bit of a size issue

[subframe7536]

both are not solved... cannot figure out why

[Cyberczy]

lll have no issues

Sorry, seems like there's still a bit of a size issue

[Cyberczy]

both are not solved... cannot figure out why

Thanks for the great work here! The issue may be resolved quickly.

[subframe7536]

So, if there is no enough space to render, the font size will be decreased.

It seems that it is inevitable for l related ligatures, but ### can be solved

[subframe7536]

updated MapleMono-Italic[wght]-VF.zip, support both lll and ###

[Cyberczy]

I will test it tomorrow

[Cyberczy]

updated MapleMono-Italic[wght]-VF.zip, support both lll and ###

It finally took effect lol

[Cyberczy]

@subframe7536 Congratulations and happy Lantern Festival

[subframe7536]

Thanks, happy Lantern Festival!

However, it seems that the ### ligature is lost...

[Cyberczy]

It seems to be, but at least we already know what the problem is, dont we?

[subframe7536]

However, it seems that the ### ligature is lost...

After tonight's research, based on my technical level, I believe this is due to the weird font kerning of kitty

[ErrorPower2001]

I have tested the latest version of Kitty using the releases version Maple Mono SC NF, and changing the font kerning of Kitty, but the problem still persists.

# ${HOME}/.config/kitty/kitty.conf

font_family  Maple Mono SC NF

# I have tested in -4px..+4px, 80%..120%
modify_font cell_width +1px

# I have tested in -2px..+2px
modify_font cell_height +1px

And, there is a configuration of kitty font is font_feature, but I don't know how to config it for maple-font.

[subframe7536]

You should test v7-beta6. Fixes haven't be published in stable release

[Fr4nk1inCs]

The v6 font also has this issue.

[Cyberczy]

The v6 font also has this issue.

Try v7-beta

[Fr4nk1inCs]

Seems v7-beta fixes the issue.

[Fr4nk1inCs]

And, there is a configuration of kitty font is font_feature, but I don't know how to config it for maple-font.

@ErrorPower2001 Like this:

font_features MapleMono-NF-CN-ExtraLightItalic -zero +cv01 -cv02 +cv03 -cv04 -cv99 -ss01

[K4R7IK]

@Fr4nk1inCs Where can I find the v7-beta?

Nevermind, found them.
