The plans for Color Emojis

[actionless]

@neeasade previously mentioned that in the potential todo list (#82)

what's your current thoughts on merging in https://github.com/odknt/st ?

i just did a quick smoke-testing and it seems to work:

i think together with font2 which we are already supporting (which would fix fontsize for emojis) - it should be looking alright, without problem with the width

[actionless]

also, @odknt, i've noticed that in general by the feature-set your fork of st is quite similar to ours - so mb you'll be interested to develop together one common application?

[odknt]

I have used xst in the past and am interested in improving it, so I may create a PR, though I can't promise.

I have rewritten the source code in my fork to use cairo instead of libxft to support color emoji, but it seems to be supported by libxft since 2.3.5.

Therefore, I believe that xst can display color emoji with a simple modification.

[odknt]

After a little checking of the source code, we found that xst already supports color emoji.
I was able to display color emoji by adding color=true to the font attribute specified in st.font_fallback in .Xresources.

Also, the font2 specification in config.h was broken and could not be used.
If st.font_fallback in .Xresources is not specified, fonts_count is never set, so the font specified in font2 is never loaded.

did you managed to make it work on practice? 🤔
if so, could you please share the screenshot and the st.font string?

to my knowledge it's not intended to work with colors emojis

oh, my bad, i found the issue in my test setup - i was using Emoji One font which wasn't working, but another font, Noto Color Emoji worked allright - so i think it may be due to svg-format font or smth like that

so after setting it like this it actually worked:

st.font: Monospace:pixelsize=26:antialias=true:autohint=true;
st.font_fallback: Noto Color Emoji:pixelsize=20:color=true,Meslo LG S for Lcarsline:pixelsize=22,DejaVu Sans Mono:pixelsize=25

and as i was forseeing, indeed alt_font thing fixed the width problem

also, is there specific reason you chosen to use cairo there, @odknt ?

and btw you're still welcome to join the development as for example another feature you're maintaining in your fork is also in our list: #47

Also, the font2 specification in config.h was broken and could not be used.

it was broken when building xst with -flto=auto, but i finally found a moment to fix that: #164

[odknt]

When I forked st, libxft did not support color emoji. So I had to rewrite it by using cairo.

I honestly don't know much about SIXEL support, as I just merged patches created by others.
