Add live preview to theme picker by jharrilim · Pull Request #1798 · helix-editor/helix

jharrilim · 2022-03-12T06:47:36Z

I'm probably annoying at this point, as I'm spamming this repo with my experiments. This one was fun though. It even reverts back to the original theme if you didn't select any. Perhaps it's a good start?

misc stuff:

~~Also added theme caching to reduce FS reads (although tbh it might be better to load them at the start)~~
~~Added more callbacks to the picker~~
A last_theme property is used now, this is useful for when a user cancels the theme preview so we can reset back to that theme
TypableCommands now must declare a list of PromptEvents they want to react upon

A better way to approach this would be to implement live preview on :theme <TAB>, so that you can see how the syntax highlighting for code changes on each theme. IIRC it was attempted before but dropped because of some architectural challenges, but I think it might be easier to implement now. And experiments are never a bad thing :)

A better way to approach this would be to implement live preview on :theme , so that you can see how the syntax highlighting for code changes on each theme.

Agreed, that seems like a good choice. I was going to fiddle with setting a smaller height to the picker, but the :theme command has that going for it naturally. I'll try poking around with that too!

@the-mikedavis sorry for the wait! This is ready to be re-reviewed.

(I had initially been distracted by Elden Ring if that's fair)

Is there any other typable commands we could live preview?

archseer · 2022-06-26T08:39:36Z

+    /// Use `prompt_events` to declare which events this command will respond to.
+    pub prompt_events: u8,


Is this really worth it? It adds extra complexity. I'd just always call the prompt

And then return early inside the function. That way it behaves exactly like regex_prompt and other command prompts.

I had that initially, but swapped to this approach to avoid touching the existing functions: #1798 (comment)

I don't think it's going to be a clean revert at this point unfortunately

I don't have strong opinions on either approach. If you confirm that you'd prefer what was done originally I'll change it back, but I'll only do it one more time or else I might get tendonitis 😳

Yeah I'd prefer to handle these inside existing functions, it's a bit more flexible. Sorry for the trouble!

Switched it back, should be good to go!

goto_line_number is a great candidate for that IMO.

For not-so-live-previews, I could imagine it might be nice a nice option for showing the contents of the clipboard if the size of the yank isn't too large.

~~Indent style~~ (we don't change existing stuff) and substitution (we don't have this) that I know of? If anything I find only live preview for theme picker far more useful than anything, at least don't have to select theme and go out, and select another one. The others that I know live preview is not that useful since we already have an expected result in mind.

archseer · 2022-07-01T09:32:51Z

goto_line_number is a great candidate for that IMO.

That's a good point! Feel free to exclude that from this initial PR though.

contents of the clipboard

We do show a register preview window you can use when selecting registers before pasting ("). But it doesn't cover the system clipboard.

jharrilim · 2022-07-02T21:03:16Z

That's a good point! Feel free to exclude that from this initial PR though.

Agreed, let's keep that separate, it'll be easier to review that way

Looks good to me.
