Transparent background in editor

[dontlaugh]

I have a transparent terminal. I like the way it looks.

In the acc editor, the line numbers have a transparent background, but the editor area does not.

Is there a way to configure a transparent background for both?

Thanks for your issue! 😄

No, now. But it can be implemented.

Could you share your environment(OS, terminal software)?

It looks good in macOS + iTerm2.

My OS is Manjaro Linux with the Xfce desktop.

Here are a two terminals:

Kitty https://sw.kovidgoyal.net/kitty/

Xfce Terminal

The Kitty terminal is capable of transparent background colors, since the status bar can do it. For example:

So, unfortunately, that status bar is a part of kitty terminal's internal UI. It's not really a terminal program. All other terminal programs I've run in linux have opaque background colors. 🤔

So I think my only path forward is to not set a background color at all in acc. I'll try it out.

[dontlaugh]

I don't know if it is possible to do this with edits to the .tmTheme file only. :(

[hatoo]

I confirmed that it is not applied transparency if the background color is different from the terminal's default color on Kitty with mac.

I think it can be resolved by adding a config that not to render background-color on editors' screen.

How do you think?

[dontlaugh]

That might work. I could not figure out how to do that with edits to the xml file (and rebuilding). Maybe there is another command we can use from the syntax library.

[hatoo]

Currently, acc uses Solarized (dark) which is hardcoded in syntect as the theme. and it's not configuable
note: assets/One Dark.tmTheme is not used now.

Accepted/src/syntax.rs

Lines 55 to 63 in 615885d

	pub fn load_syntax(&self, extension: &str) -> Option<Syntax> {
	let syntax = self.syntax_set.find_syntax_by_extension(extension)?;
	// let theme = ThemeSet::load_from_reader(&mut Cursor::new(theme::ONE_DARK.as_bytes())).unwrap();
	Some(Syntax {
	syntax_set: &self.syntax_set,
	syntax,
	theme: &self.theme_set.themes["Solarized (dark)"],
	})
	}

Maybe we should just make a syntax file configurable.
Is it enough for you?

[dontlaugh]

Runtime configuration would be good!

[hatoo]

I've succeeded to draw transparent background on kitty on macOS by setting a theme whose background is #000000.

Could you share your screenshot?

[dontlaugh]

It works! This is a new computer, but for some reason it's working here. I am traveling, I will try it on my other devices when I get home in a few days.

Environment: Manjaro Linux, Xfce Desktop, Kitty v 1.16

On my other desktop I did have an older version of Kitty, because it is a Ubuntu-based machine and the package manager is not up to date. But the good news is this is my new main laptop! :)

[dontlaugh]

I used the path-based configuration you provided as an option in #15 and copied the OneDark theme into a new file at $HOME/.config/acc/themes/Test.tmTheme, and provided the full path to that theme. And edited the background config to 00000.
