feat(backend): add termwiz backend and example #5

orhun · 2023-02-12T21:58:53Z

Upstream: #300

Added termwiz backend which currently is tested in archlinux and works. It is using BufferedTerminal internally which should be doing diffs before applying the changes when calling flush.

As for windows it does compile but for some reason I don't see right chars being rendered.

//cc @wez

prabirshrestha said: @wez any idea why it doesn't render correctly in Windows? Once I quit alt screen also doesn't seem to go back clean. On linux it works as expected.

orhun · 2023-02-12T21:58:59Z

fdehau said: Thanks for the contribution. From a first read the code looks good. However, I'm a bit skeptical on the need for a new backend. Are there capabilities that are only provided by termwiz ? I was not aware that this crate existed until now, but my first impression is that it is a bit higher level than other backends and thus be seen as an other great take on a "framework" to build terminal applications. @wez what is your opinion on this ? I would be more than happy to list it as an alternative to tui as I've done for cursive.

orhun · 2023-02-12T21:59:00Z

wez said: @fdehau: My vision for termwiz is to enable cross platform (including first-class Windows support) text applications to detect and use a wide range of modern features in terminals, not only true color output (with a means to specify fallback on terminals that don't support it), but also including things like hyperlinks (OSC 8) and image protocols (currently iterm2 is supported, but I plan on adding sixel output soon).

termwiz has good low level foundations and optional nascent higher level support; it has an optional widget layer that is currently a bit lacking. termwiz shares the same core terminal model as wezterm, and my intent is that both will support a wide range of terminal attributes and display options.

I haven't looked at the internals in tui so I can't say whether you'd benefit from targeting the lower level API in termwiz or not, but I would suggest that it is worth evaluating that. The higher level stuff sounds like it may be a "competitor" to tui, but termwiz's widgets are pretty far behind in that "race" today :-)

orhun · 2023-02-12T21:59:01Z

prabirshrestha said: Currently wezterm widgets are very primitive so would like to use tui-rs instead. Given that I use wezterm as my terminal emulator I find it great that the same library can also be used for tui-rs which means any bug fixes or perf improvements that goes to wezterm comes for free by termwiz. termwiz does support different sent of features as mentioned earlier.

On windows there is currently only one backend so having a second backend would give more options to users.

Given that tui-rs doesn't have its own input handling apis I would like reuse the apis I'm already familiar with termwiz to build apps.

orhun · 2023-02-12T21:59:03Z

fdehau said: Thanks @wez for the nice overview. This is a very impressive and ambitious project so if adding support in tui can give it a bit more spotlight I would be more than happy to do so. Thanks also @prabirshrestha for detailing how you plan to use this new backend. Both of you made a good case :). As I said before, the code looks good so I'm wondering if @prabirshrestha want to investigate the Windows issues first or merge as is and iterate on the Windows support later ?

joshka · 2023-05-03T05:27:56Z

Rebased on main, updated termwiz to 0.20, updated changes that had been made to termwiz lib since 0.9 (e.g. cell.style.fg -> cell.fg) and moved demo to the right place.

orhun · 2023-05-03T11:09:05Z

We should probably update Makefile.toml to test it against this feature, right?

joshka · 2023-05-03T13:50:09Z

Probably - I'll take a look at that sometime soon.

joshka · 2023-05-04T04:08:23Z

Looks like we need to bump msrv to 1.60 for this.

error: package `phf_shared v0.11.1` cannot be built because it requires rustc 1.60 or newer, while the currently active rustc version is 1.59.0

joshka · 2023-05-04T04:33:14Z

Make that 1.63

error: package `time v0.3.20` cannot be built because it requires rustc 1.63.0 or newer, while the currently active rustc version is 1.60.0

sophacles · 2023-05-04T16:20:30Z

I don't thing the time thing is related to this PR directly - that dependency only comes via the widget-calendar feature, and isn't used for wezterm stuff.

It's specified as:

time = { version = "0.3.11", optional = true, features = ["local-offset"]}

I'm not sure why 0.3.20 is getting pulled in for the builds. I'm not opposed to using the latest time crate (or at least latest compatable version) or bumping MSRV, but it might be some sort of smell that it's showing up in this unrelated PR.

sophacles

Nice - thanks for the work on this!

A request for 0.3.11 is a request for any 0.3.x where x > 11

I initially bumped MSRV to 1.60, which was necessary, but then got the other error for 1.63 due to time. Yeah, the 1.63 bump doesn't have to be part of this PR, but a MSRV bump does have to happen. My logic was that we may as well jump straight to 1.63 instead of the intermediate step.

orhun · 2023-05-09T18:03:15Z

So what exactly is the source of the MSRV change?

I see that it is related to calendar widget but what is the correlation between this PR?

When I rebased on main, the first thing that the ci picked up as failing on 1.59 was phf_shared (noted in #5 (comment), but the CI run has expired, so I can't point to the error).

I then bumped MSRV to 1.60 and hit the next MSRV requrement for time (1.63) in #5 (comment)

That MSRV bump is needed the time crate in the calendar feature.
So this PR is not strictly required to bump to 1.63, but it requires an MSRV bump, which I discovered during this PR.
I'll move the bump over to a separate PR as it's not related to this.

joshka · 2023-05-09T20:23:29Z

I rebased this on main, incorporated your fixups (spacing and vscode), and changed the MSRV bump back to 1.60.0.

The CI checks for this fails as it updates the time crate to the latest version which now requires rust 1.65.0:

joshka · 2023-05-09T21:20:26Z

In #171 I bumped the MSRV to 1.65.0. I've rebased this PR on top of that one, and removed the MSRV 1.60 commit. Assuming that PR is merged, I think this would be also ready to merge.

joshka

Approving as @orhun made the initial PR and although I fixed it up, this needs 2 approvals.
🤷‍♂️
Only merge this based on @orhun's actual approval though.
