Support using `heh` as a Ratatui widget #120

orhun · 2024-03-30T21:30:07Z

Hey! 🐻

I'm currently working on a TUI that allows analyzing ELF files and I would like to have heh as a component in there because I think it is a pretty awesome app! (and I don't want to rewrite the same functionality :D)

This PR simply makes that possible!

The summary of the changes:

Created lib.rs for using heh as a library
Made some types public (primarily Application, Encoding, ScreenHandler, ComponentLayouts)
Added a new function Application::render_frame for rendering a single frame.
- This can be refactored into impl ratatui::widgets::Widget for Application but it requires some additional work on restructuring the internal types.
- There is a bit of a code duplication there which I couldn't avoid due to ScreenHandler holding some state - i.e. I can't mutate it inside the terminal.draw closure.
Added documentation

See this commit for the implementation in my app.

Demo (see the "hexdump" tab):

Cheers!

Moves the module definitions to lib.rs and exposes some types for usage

Adds App::render_frame method

Wow, this is amazing! I'll try and review and come back to you in a couple of days. I've been really busy with life lately, so I haven't had the time to really give this repo as much love as I want.

You demo looks really really cool, and I'm glad you could make use of heh :)

Wow, this is amazing! I'll try and review and come back to you in a couple of days.

Thanks a lot! I will be looking forward to your review and happy to improve the code 🐻

I've been really busy with life lately, so I haven't had the time to really give this repo as much love as I want.

I'm thinking of submitting some other PRs, mainly about updating Ratatui to the latest version. Happy to work on other issues as well.

You demo looks really really cool, and I'm glad you could make use of heh :)

Right now it is fully functional and I am so satisfied with it. Thanks for building heh, it's a killer!

Thanks for waiting, I think this looks good for the most part!

One thing I wanted to get your input on was the module_name_repititions clippy error that we're getting with LabelHandler, ScreenHandler, and AppData - to fix this, I'm thinking of changing the names of these structs right now and users of the library would have to specify screen::Handler, label::Handler, and app::Data. I'm of the mind that this is probably better for the longevity of heh as a library, but was curious what you thought.

There are other clippy lints failing, but if you don't have the time to fix them, I can go ahead and get around to cleaning the up after I push this through -- I don't wanna block any progress on your work!

Also let me know if after this gets merged, you would want me to make a release :)

+```rust
+heh.handle_input(crossterm::event::Event::Key(/* */)).unwrap();

Feel free to add a link to binsider as an example use case of using this as a library!

Thanks!

+    pub fn render_frame(&mut self, frame: &mut Frame, area: Rect) {


Would you be willing to create an issue so that at some point I remember to create tests specifically for render_frame and handle_input? I'll have to look into it but I think I'll want more coverage on these now that they'll be library functions.

Beep beep, you got it!

One thing I wanted to get your input on was the module_name_repititions [...] to fix this, I'm thinking of changing the names of these structs right now and users of the library would have to specify screen::Handler, label::Handler, and app::Data

I think that would be perfect! I personally never liked the name "Handler" (reminds me of Java 🤮)

Do you want me to do it in this PR or are you going to work on that separately?

There are other clippy lints failing, but if you don't have the time to fix them, I can go ahead and get around to cleaning the up after I push this through -- I don't wanna block any progress on your work!

Works fine for me, thank you!

Also let me know if after this gets merged, you would want me to make a release :)

Please do 🙂

I'd appreciate if you could do it in this PR! Haha you can tell I come from Java xD

After the names are fixed to your liking, I'll merge this and hopefully have the time to push a release 👍

orhun · 2024-04-07T21:42:58Z

Okay, one issue:

use crate::{app::Data, label::Handler, screen::Handler};

In that case we are importing both Handlers which causes a conflict. We can solve this by using a type alias (e.g. as LabelHandler) but I'm not sure. What do you think?

I will think of an alternative name.

ndd7xv · 2024-04-07T21:47:26Z

Using an alias is what I had in mind! I completely trust whatever alternative names you come up with too.

orhun · 2024-04-07T22:26:52Z

Okay, all should be good now. I renamed the types and fixed the lints.

Let me know 🙂

ndd7xv

Thanks! I'll try and get a release out soon, I really appreciate your PR :)

ndd7xv · 2024-04-08T04:03:33Z

Just created a release 🥳 let me know if there's anything else I should do, thanks again!

orhun · 2024-04-08T10:51:26Z

Awesome, thanks a lot for your cooperation on this!

Here I bumped the heh version and everything is seamless!
