Ugh, looks like DESTDIR=$out was not correct after all, fixing...

This seems to have a duplicate "prefix", result/nix/store/xxx..../bin/gxi vs result/bin/gxi? I'm trying a build w/o setting DESTDIR to see if that fixes things, not sure. (EDIT: sorry was using outdated info, this appears resolved now)

FWIW, previously: #48593 .
Which I was encouraged to make available elsewhere until xi was more "stable".
Accordingly, may want to check out my NUR repo: https://github.com/dtzWill/nur-packages/,
particularly: https://github.com/dtzWill/nur-packages/tree/master/pkgs/xi and especially https://github.com/dtzWill/nur-packages/blob/master/pkgs/xi/gxi/default.nix .

I would be happy to see this (and perhaps others) in nixpkgs proper, or otherwise improved and made available for folks to explore!

There might be better ways to approach this than what I did, but it does handle something I don't think is tackled here: rigging up the xi-syntext plugin so that syntax highlighting works out-of-the-box.
(You still need to select filetype from the drop-down, but it otherwise seems to work! Well, other than the unforgivable (:wink:) omission of highlight support for Nix files!

I haven't poked at this much recently (beyond automated updates), but offhand it might be better for gxi in particular to do something more like what you have done re:all-in-one to avoid mismatches between frontend and backend versions. Although I forget if that's a concern 😇.

Oh the syntect plugin is handled here now too, great! That was the main technical point, glad it's handled automagically.

Yeah I noticed that problem. I'm setting DESTDIR precisely because the meson postinstall script was failing otherwise. Still no clue why, it wouldn't print out anything...

This was just a mostly clueless attempt at packaging gxi so I don't have to use atom. Anyway this does set up xi-syntect-plugin. Your setup seems to allow for much better sharing of derivations down the line though so I'd probably prefer that route. Would be nice to be able to use a shared LSP plugin installation for all xi frontends. Plugins and frontends AFAIK should not be tied to any specific core version, but until 1.0 there are of course no guarantees about that.

TIL about NUR. I guess I'll just close this until we figure out a proper clean setup...

Let's move discussion to the xi-editor Zulip instance.
