Also try C-x p g for a similar UI.

Customize xref-search-program to make it use ripgrep under the covers.

Regarding elixir-ts-mode in particular, as noted in https://debbugs.gnu.org/67246, its highlighting is currently being reworked.

The font lock rules in a lot of the TS modes are… not always thought through. Ramp up python-ts-mode’s font lock level to the maximum and most of everything is dyed the same colour.

And then on the other side, people come asking why even when TS is used, highlighting is not “up to par” with VS Code and etc. Then hear about treesit-font-lock-level, ramp it up to the max, and apparently live happily after.

So your complaint is about the non-default behavior? The level 3 was chosen as default explicitly to avoid the abundance of color where it’s not really needed.

I said monochromacity: that at the highest level, many disparate node types are font locked with the same face. Try it in Python. Everything is the same shade of whatever your variable name face is.

I don’t see that “everything is the same shade”, even with level 4. There are problems - like the variable matches in particular (which is not useful IMO, but should at least use a different face). The rest use different faces, but since most of those faces are new, it’s up to the theme authors to differentiate them.

Here’s a patch fixing the one problem I found (try it), and below is a screenshot with this patch applied along with the new faces customized to be distinct.

You’re welcome.

Have you tried to use the same binding? python-ts-mode should have the same default set as python-mode due of how python-ts-mode-map is defined.

To see all available bindings, type C-h f python-ts-mode RET. You’re probably thinking of C-c < and C-c >.

What’s going on on the gif doesn’t look particularly smooth, so as long as the horizontal steps are limited to multiples of the character width, this should be easy to write in Emacs Lisp (5-10 lines).

But doing something practical with it will require extra work. I.e. the depicted process is probably a part of some specific buffer management/switching mechanism, and that would require some extra analysis to replicate and integrate.

Ah, actually, Emacs supports pixelwise window resizing as well.

So it basically comes down to choosing (and implementing) the window management logic which would do something like this for the sake of anything practical.

And making sure that no third-party packages slow down redisplay enough that this movement becomes too jerky.

These two bindings work for me. Does C-h f python-ts-mode RET show them in the list?

Like the article mentions, gestures could be even more handy when used with a touch interface.

Such as the new Android port of Emacs, for example.
