lsix VS Weechat

In XTerm, this (rightly) makes no difference. In Foot and Contour however, you still end up a line resp. a screen below where you started, if now with the correct horizontal position.

So it seems to me like what you want should work by default, except it doesn’t.

It should be possible to instead just treat the whole thing as a graphical overlay (by computing or directly asking for the character cell size, as Kirill Panov rightly admonishes me is possible with XTWINOPS) without touching the cursor; that’s what the “sixel scrolling” setting (DECSDM) is supposed to do. Then you can just manually move the cursor forward however many positions after you’re done drawing.

Except apparently the DEC manual (the VT330/340 one above) and DEC hardware contradict each other as to which setting of DECSDM (set or reset) corresponds to which scrolling state (enabled or disabled), and XTerm has implemented it according to the manual not the VT3xx[1,2,3]—then most other emulators followed suit[4]—then XTerm switched to following the hardware[5,6] (unless you and that’s what I’m seeing on my machine right now. So now you need to check if you’re on XTerm ≥ 369 or not[7]. If I’m reading the Notcurses code right, other terminals have followed suit[8].

Again, ouch.

P.S. It seems DEC had an internal doc for how their terminals should operate (DEC STD 070) [9]. It does not document DECSDM at all.

Sixel - Sixel is a standard from the 1970's/1980's DEC VT series. It has enjoyed a tremendous resurgence in popularity thanks largely to saitoha's libsixel project. Many projects are now using sixel; a few you may have heard of include lsix, chafa, and notcurses.

I would point out that sixels[0] exist. There is a nice library, libsixel[1] for working with it, which includes bindings into many languages. If the author of sixel-tmux[2][3] is to be believed[4], the relative lack of adoption is a result of unwillingness on the part of maintainers of some popular open source terminal libraries to implement sixel support.

I can't comment on that directly, but I will say, it's pretty damn cool to see GnuPlot generating output right into one's terminal. lsix[5] is also pretty handy as well.

But yeah, I agree, I'm not a fan of all the work that has gone into "terminal graphics" that are based on unicode. It's a dead-end, as was clear to DEC even back in '87 (and that's setting aside that the VT220[6] had it's own drawing capabilities, though they were more limited). Maybe sixel isn't the best possible way of handling this, but it does have the benefit of 34 years of backwards-compatibility, and with the right software, you can already use it _now_.

no, I found it and it's called lsix

WeeChat[0] with Bitlbee[1] supports a metric assload of services, albeit by pretending they're IRC (which does work - I spent years in weechat/irssi with bitlbee talking to various people on disparate services.)

Or if you're just after Telegram/WhatsApp, nchat[2] is ok (I can vouch for the Telegram half only.)

And UnrealIRCD still rocks. For a quick-and-dirty setup I've deploy ng-ircd but Unreal has always been my go-to for anything serious. If nothing else it can be useful as a backup or internal platform during the rare events that Slack or Discord are having an incident. The common complaint is a lack of channel back-log but it can be front-ended with TheLounge [1] or Convos [2]. I personally prefer to handle that with gnu screen or tmux and WeeChat [3].

I’m afraid you’re in the wrong subreddit. This subreddit is dedicated to WeeChat the IRC client., not the proprietary messaging app built by Tencent.

First off, grab yourself an IRC client. On their connection info page Hackint has information for both WeeChat and Hexchat, but you could use any IRC client.

That's nothing to do with weechat? https://weechat.org/

Gajim is for XMPP. For IRC you need Hexchat or Weechat or something like that.

I am not familiar with HexChat but you might consider using a different IRC client that allows you to silence anything/everything by default and only alert you on specific keywords you are interested in. If you like command line tools, consider trying out WeeChat IRC client [1] It is very customizable and there are many scripts for it.
