Re: [SOLVED] Should urxvt wiki mention colored emojis are not supported?

where to move it?

Newbie Corner.

The font lacks the latin alphabet

urxvt: unable to calculate font width for 'Noto Color Emoji-9:slant=0:weight=100:minspace=True', using max_advance_width.

You may try one of the patched urxvt variants from the AUR for more lenient glyph handling.

eg. https://aur.archlinux.org/packages/rxvt … wideglyphs (idk. whether the patch to the patch I posted there still works)

Edit: patch on patch still works

But there's a comment, showing an error, more recent than your comment. I get that very same error.

And what is the "patch on patch"?

Re: [SOLVED] Should urxvt wiki mention colored emojis are not supported?

https://aur.archlinux.org/packages/rxvt … ent-881950 patches enable-wide-glyphs.patch which itself is a patch provided by the package on top of the urxvt cvs checkout.

The other comment simply didn't apply that patch, I rebuilt the package this morning to test whether something had broken again.
Also b

new sha1sum for 'enable-wide-glyphs.patch' is '764db81b7a1618bf24a3d512b088815d479a97a6'

Re: [SOLVED] Should urxvt wiki mention colored emojis are not supported?

Sorry, I don't know how to apply that patch. Considering enable-wide-glyphs.patch itself looks a lot like a git diff redirected to a file, I'm not sure whether I'm supposed to manually apply the diff of your comment or to put it in a file to make it have an effect. I've tried putting it in a file  enable-wide-glyphs.patch.patch, and then run makepkg -si. It did have an effect, as I was asked quite a few

Reversed (or previously applied) patch detected!  Assume -R? [n]

and answered y to all, but the procedure failed anyway. Can you give me more details as to how to apply the patch?

Ok, never mind, I've found the wiki.

However, it's not clear to me how to apply the patch. Here is my attempt to do it. What did I do wrong? (Patch and sha is copied from your comment, steps are from the wiki; I did makepkg to trigger the creation of src/ and the copy of the patches in it; not sure if that's what I needed)

You "git apply the_extra.patch" (I didn't include the shasum because I'm more changes to the PKGBUILD, enabling pixbuf and disabling frills)

But here's the the_extra.patch

Re: [SOLVED] Should urxvt wiki mention colored emojis are not supported?

Do you mean I'd do that in a freshly downloaded git repo from there? If so, here's how it ends:

:: rxvt-unicode-cvs-patched-wideglyphs and rxvt-unicode are in conflict. Remove rxvt-unicode? [y/N] y

Packages (2) rxvt-unicode-9.31-2 [removal]  rxvt-unicode-cvs-patched-wideglyphs-20170412-12

Total Installed Size:  3.20 MiB
Net Upgrade Size:      0.01 MiB

:: Proceed with installation? [Y/n]

but the newly installed still shows squares with echo -e "\U1f34c\U1f680"

If you mean I'd do the git apply patch somewhere in the process I attempted, then when should I do it exactly?

Re: [SOLVED] Should urxvt wiki mention colored emojis are not supported?

Do you start it with the proper font configuration?

urxvt -fn 'xft:DejaVuSansM Nerd Font Mono:size=12,xft:Noto Color Emoji:size=9'

Also, sanity check

fc-list | grep -i nerd

Oh, darn it, I forgot that obvious thing.

It works!

Thank you very much

Re: [SOLVED] Should urxvt wiki mention colored emojis are not supported?

See the xrdb wiki again how to configure urxvt properly and fyi, you've now pixbuf support, ie. background images.

Re: [SOLVED] Should urxvt wiki mention colored emojis are not supported?

Isn't the following line in ~/.Xdefaults enough?

URxvt*font:             xft:DejaVuSansM Nerd Font Mono:size=12,xft:Noto Color Emoji:size=12

and fyi, you've now pixbuf support, ie. background images.

Wow, great!
