svg-tag-mode VS ligature.el

That is a module that let's you replace occurances of regexes with svgs (https://github.com/rougier/svg-tag-mode)

https://github.com/rougier/svg-tag-mode is one ingredient, which makes org documents look more fancy.

You're looking for svg-tag-mode. It's on ELPA and MELPA, so you should be able to just use-package one of those (don't forget to package-refresh-contents).

tag looks like from https://github.com/rougier/svg-tag-mode/tree/07640c97a1dcc305010a384fffdaa7788c342da7

I agree, that's a really great example. It would be even more natural for tags in org-mode, which already supports drawing tags away from the text itself to a far-right column, but they really could be moved in the other direction to the left of a hairline next to the bullets, and they'd be more readable.

BTW, Nicolas has a lot of interesting packages exploring use of graphical design elements in Emacs apart from the Nano Emacs stuff; for example, there's https://github.com/rougier/svg-tag-mode. I love how he chooses to represent dates and dates with times attached, and to distinguish active vs. inactive dates with shading rather than "[" and "<". That actually makes it easier to spot a common org-mode mistake without having to call up the agenda.

It's here: https://github.com/rougier/svg-tag-mode/blob/main/examples/example-2.el (just evaluate the whole buffer)

Specifically this is the one: https://github.com/rougier/svg-tag-mode

Apparently "smart kerning" uses the ligatures mechanism. I use Mickey Peterson's ligature.el package for ligatures support. To get the smart kerning to work I added more ligatures by hand using this package. For example the website shows the effect when you type "Moi": the "o" will shift a bit away from the "M" when you type the "i". To get that to work I added a "Moi" ligature:

It sounds like you might want ligatures? I use ligature.el but it only works on emacs version 28+.

I'm using use-package as my package manager and the package ligature for the ligatures.

https://github.com/mickeynp/ligature.el will do it, but there are specific emacs version requirements and you have to enumerate all of the possible ligatures in your config. They have some examples of configuration for various popular programming ligature fonts.

Version 28 finally includes a necessary patch that has freed up ligatures. ligature.el seems to be the winning implementation.

There's a package called "ligature.el" that only works on Emacs V28+ https://github.com/mickeynp/ligature.el

> Is that the only way, or is there a way to disable ligatures but keep the rest of the font?

It's actually not that easy to use them with for example Emacs where you have to list every combination that you want to 'translate' to a ligature:

https://github.com/mickeynp/ligature.el

ligatures are when multiple characters appear to combine into a single character ej, => transforms to arrow. emacs version and font used must support this to use it. GitHub - mickeynp/ligature.el: Display typographical ligatures in Emacs

I don't really use any sort of symbol mode very often but when I do I much prefer using ligature.el with Fira Code.
