Leptos 0.6-0.7 Migration Helpers

List of regex substitutions to help migrate a Leptos app from Leptos 0.6 to 0.7

Using with Vim/Neovim

The provided example regex for each step can be run in Vim/Neovim by using :% followed by the regex to apply to the current buffer. You can also use :cfdo % instead to apply to all the files in your quickfix list. So to put this all together, use something like the telescope file finder to find all .rs files, press ctrl+q to send them to the quickfix list, then :cfdo %s/create_resource(/Resource::new(/g and that will apply the create_resource rename.

If you are experiencing Bevy's renderer freezing until you resize the window and are on KDE plasma with wayland, this workaround might help you.

It's normally accompanied by this warning [source]:

Couldn't get swap chain texture. This often happens with the NVIDIA drivers on Linux. It can be safely ignored.

Setup I was experiencing this on:

KDE plasma: 6.1.2
Nvidia driver: 555.58.02
Kernel: 6.9.9-arch1-1

This guide shows you how to configure KDE Plasma's window rules to position a window matching a criteria whenever it opens and prevent the window from gaining focus. Specifically I use this in combination with automatically rebuilding and launching my Bevy game whenever a file changes using cargo watch -i assets -- cargo run --features=bevy/dynamic_linking --features=bevy/file_watcher. This allows me to see changes as I'm writing my Bevy App but not loose focus from my editor.

Set the "Window.name" value in your bevy app to something specific to your app.

fn main() {
    App::new()
        .add_plugins((
            DefaultPlugins.set(WindowPlugin {
                primary_window: Some(Window {

Bevy 0.11 migration with ast-grep

Uses ast-grep to apply some parts of bevy 0.10 to 0.11 migration that can be automated.

You should review any changes this makes.

cargo install ast-grep
sg -p 'Clicked' --rewrite 'Pressed' -U
sg -p 'LAlt' --rewrite 'AltLeft' -U
