Helpful #git tip of the day 📢 🤓

If you want to find a particular string (via regex) over all of your commits (be it added, moved or deleted) you can pass the -G option to `git log`.

Example:

git log -G"[Tt]he [Nn]eedle"

Go with -i for case-insensitive match (thank you @nafmo for pointing it out)

⚠️ Warning: There is a similar option with `git log -S --pickaxe-regex`, but it _won't_ show _moved_ lines, only added/deleted lines!

Yes, THIS!

~2 years ago I've done a test where I've asked the LLM a coding related task:

"There is a bug in the code, Can you find it?"

...but there was no bug. Guess what the LLM did... 💩

Some #Rust string literal #trivia - the following are equal:

let s = "one line string";

let s = "one line \
string";

And these ones are also equal:

let lines = "a\nmultiline\nstring";

let lines = "a
multiline
string";

and now my favorite... 🥁

let lines = "a\n\
multiline\n\
string";

All these "state management" solutions of the "modern web" like #Redux, Zustand or whatever try to solve state management in UI apps by introducing unfathomable amount of complexity...

...when in reality all you need is #Bevy's #ECS. ¯\_(ツ)_/¯

@alcinnz Ha, thank you for the link, Adrian!🙂

I've just watched the whole thing - what a deep dive!

> I like that Sebastian Lague included his failures...

Yes, totally agree! Very humble. In the end, we are all human and struggling with things is just part of the process of creating something.

Implementing Drag & Drop is hard!

*click*?.... No, there was movement!

What should happen if people, during drag, accidentally push another secondary (mouse) button? Should the drag & drop process "abort", "pause" or "finish"?
In the case of "pause":
How can someone resume the drag & drop process then?

What should happen, if the mouse is out of the workspace area or another object is between the dragged object and cursor?

So many states and workflows to consider...

The test suite [includes] fuzz tests, boundary value tests, regression tests, and tests that simulate operating system crashes, power losses, I/O errors, and out-of-memory errors."

Let's go! 🚀

Hilarious!😅

Oh nooees!!😢 #Bevy 0.15 breaks #UI tests.😭 Layouts are not calculated anymore in tests.

It apparently requires a different setup of the `World`, but I'm not sure how to set it up.

I've used CameraPlugin, WindowPlugin, UiPlugin etc., but it still doesn't work (works in 0.14 though).

I've seen this setup from Bevy repo, but it seems a bit too granular for me (I prefer using bunch of Plugins):

https://github.com/bevyengine/bevy/blob/2931e350b6d4782c311900e602e1e7713f35c9c4/crates/bevy_ui/src/layout/mod.rs#L511

Have to look more deeply into it tomorrow.

3. Me suspecting UiPlugin (because where to render?)
4. `Go To Definition` of UiPlugin
5. Seeing the following definition:

pub struct UiPlugin {
/// If set to false, the UI's rendering systems won't be added to the `RenderApp` and no UI elements will be drawn.
/// The layout and interaction components will still be updated as normal.
pub enable_rendering: bool,
...
}

Hm, well that `enable_rendering` seems "suspicious" to me, so let's deactivate that and see what happens...

2/?

6. Set `enable_rendering` to false:

app.add_plugins(MinimalPlugins.set(ScheduleRunnerPlugin::run_once()))
.add_plugins((
TransformPlugin,
HierarchyPlugin,
WindowPlugin::default(),
UiPlugin {
enable_rendering: false,
..default()
},
DefaultPickingPlugins::default(),
))
.add_plugins(NodeSelectionPlugin);

7. Execute test...

Ah, YES!! I've finally been able to fix my weird bug I'd run into after upgrading my #Bevy toy project from 0.12 -> 0.15! :awesome:

I've almost gotten insane!😖

Very happy now!😊

I've suggested some more examples in migration guide from 0.14 -> 0.15 (which was the reason for my app breaking):

https://github.com/bevyengine/bevy-website/issues/1920

Hopefully others are now less likely to run into this (it's so gnarly, because no compile error). 🤞

See below for my toy project if you're interested 😄

#UI #BevyEngine

#Bevy is just AMAZING (see also next posts🧵)! :awesome:

1. Want to unit test #UI Plugin.
2. Following setup runs into infinite loop:

let mut app = App::new();
app.add_plugins(MinimalPlugins.set(ScheduleRunnerPlugin::run_once()))
.add_plugins((
TransformPlugin,
HierarchyPlugin,
WindowPlugin::default(),
UiPlugin::default(),
DefaultPickingPlugins::default(),
));

@garrett Aw, so glad you like it!😊

Yes, i know, right!?

I can't really put into words why I like this channel so much.

It's storytelling, design, innovation, philosophy and an eye for quality packaged into something one can call...art! ✨

@alcinnz

@alcinnz Nice, thank you for the list.

The following is not educating about computing & technology, but architecture & design (I assume you're also interested in design, so you might like it as well):

Channel is called DamiLee:

Her storytelling is very inspiring and her videos give off such positive vibes!

"So you're in computer science, but don't have a smartphone!? That's weird!"

...is the same as saying:

"So you're a doctor, but you don't smoke cigarettes!? That's weird!"

It is everything but weird!
