Option to move cursor one character back? #99

Open mentalisttraceur opened 4 months ago

mentalisttraceur commented 4 months ago

Currently, the point is placed after the node glyph instead of before.

When using Emacs in some terminals, the cursor can't be hidden, and can't be restyled, especially not per-buffer (and doing it globally for the whole terminal usually makes for worse UX over-all).

One real-world example of where you basically have to use such a terminal is in on Android, in Termux. Technically that terminal supports some standard control sequences to restyle the cursor (neovim manages to do it), but Emacs doesn't seem to know how to do it? Anyway, for me this is a huge part of my daily Emacs usage.

So it's a super minor aesthetic issue, but it seems like some users would prefer it if a can't-be-hidden/changed box cursor displayed on the node rather than to its right.

Here's an example of what it ends up looking like currently (compact, Unicode glyphs, in Termux on Android).

I think some people would prefer this or would at least find it more intuitive:

Personally, I quickly got used to it and now I think I prefer it the way that it is.

But maybe we could give users a customizable variable to choose? Or maybe we can just figure out a function that users could add to one of the existing hooks to achieve this?

(This might be related to #49 , but I don't have time to double-check right now, sorry.)

Makes sense, if someone care about this deeply enough and make a pr, I'm happy to merge it.
