NoTranslationsBundled error when dynamically changing language

[LouisBouch]

Bug Description

When dynamically changing the language with slint::select_bundled_translation("fr_CA").unwrap();, the app errors out with NoTranslationsBundled. This happens despite having followed the docs instructions.

Reproducing this error can be done with a minimal setup, which includes a Cargo.toml, build.rs, main.rs, <project_name>.po file and finally a ui.slint.

Cargo.toml

[package]
name = "slint_issue"
version = "0.1.0"
edition = "2024"

[dependencies]
slint = {version = "1.13", features = ["std"]}

[build-dependencies]
slint-build = "1.13"

src/ui.slint

import { Button } from "std-widgets.slint";
export component Example inherits Window {
    width: 200px;
    height: 150px;
    Button {
        text: @tr("Hello there");
        clicked => {
            switch_to_french();
        }
    }
    callback switch_to_french();
}

slint_issue.po
First run find -name \*.slint | xargs slint-tr-extractor -o MY_PROJECT.pot and then edit the .pot output with poedit, which can be saved to slint_issue/translations/fr_CA/LC_MESSAGES/slint_issue.po.

build.rs

fn main() {
    println!("cargo:warning=Build script is running!");
    let config =
        slint_build::CompilerConfiguration::new().with_bundled_translations("translations");
    slint_build::compile_with_config("src/ui.slint", config).unwrap();
}

This build location follows what is described in the docs and crate given my .po file in slint_issue/translations/fr_CA/LC_MESSAGES/slint_issue.po

src/main.rs

slint::slint! {
    export { Example } from "src/ui.slint";
}
fn main() -> Result<(), slint::PlatformError> {
    // Figure out translation
    let ui = Example::new()?;
    ui.on_switch_to_french(|| {
        slint::select_bundled_translation("fr_CA").unwrap();
    });
    ui.run()?;
    Ok(())
}

According to slint::select_bundled_translation, pressing the button in ui.slint should change the button's text to the desired translation ("Salut" in my case). Instead, I get a NoTranslationsBundled error.

Despite what the error tells me, I know that the build.rs does create a bundle, as I can find it in the target directory in slint_issue/target/debug/build/slint_issue-.../out/ui.rs, and it contains:

     const _SLINT_TRANSLATED_STRINGS : & [& [sp :: Option < & str >]] = & [& [Some ("Hello there") , Some ("Salut")]] ;
...
     const _SLINT_BUNDLED_LANGUAGES : & [& str] = & ["" , "fr_CA"] ;

These are the language and translation I specified in poedit.

• Programming Language: Rust

Product Impact

I am currently testing these features out before building my app. I need to be able to use multiple languages as it will be distributed to a wide variety of people.

[ogoffart]

I think I've spotted the problem:

slint::slint! {

This macro re-compiles the code again, without the bundle translations.

What need to be done here is to use slint::include_modules! macro instead.

[LouisBouch]

Hmm, I guess I didn't properly follow the docs instructions after all.
Everything works now, thank you!
