Add support for explicit hyperlink marking in terminals that support it.

[offbyone]

Feature description

When hyperlinks are posted to terminals it's super useful to be able to click on them. Most modern terminals provide URL marking features to make that possible, but they rely on text continuity, and when URLs wrap in sub-panes of the terminal window that gets hard, if not straight up impossible.

See, for example, this issue I opened to iTerm2: https://gitlab.com/gnachman/iterm2/issues/7066

They point out that there's a nascent standard implemented by them and by Gnome terminal, OSC 8 explicit hyperlink support, that allows for HTML-like anchors to mark links.

Please implement that in weechat so that I can click on my URLs again 😄

Still not clickable with alt+l ?

[offbyone]

Yeah, that works... I'm not sure it removes the value of my feature request, though.

This would be wonderful to see implemented, alt+l is an annoying workaround.

[jpmenil]

another workaround, is tmux + tmux-url-select.pl or another tmux url plugin

OSC 8 Hyperlinks are widely supported in terminals now. Would love to see this in weechat.

Hi,

As mentioned in the iterm2 issue (on GitLab), the problem is that ncurses doesn't support this OSC8 ANSI code.

I made a POC, visible in this commit: 2d38731 (very basic support, making any word starting with "http" an URL).
But this doesn't work at all, I'm not able to send raw codes to ncurses, and using fprintf doesn't help either.

I think the only possible solutions for support of these hyperlinks (which I agree would be nice) are:

• wait for OSC8 hyperlinks support in ncurses
• contribute to ncurses to add such support
• remove completely ncurses fom WeeChat and either switch to another lib supporting OSC8 hyperlinks, or no lib at all (huge work in any case).

is there an open issue somewhere or a place where we can track OSC8 hyperlink support in ncurses?
