use static_init::constructor;
use tracing::info;
#[constructor(0)]
extern "C" fn init() {
loginit::init()
}
#[test]
fn test() -> Result<()> {
let root: PathBuf = env!("CARGO_MANIFEST_DIR").into();
info!("root {}", root.display());
let yml_fp = root.join("tests").join("state.yml");
info!("has_change {}", diff.has_change);
for (fp, _meta) in &diff.changed {

## About
This project is an open-source component of [i18n.site ⋅ Internationalization Solution](https://i18n.site).
* [i18 : MarkDown Command Line Translation Tool](https://i18n.site/i18)
The translation perfectly maintains the Markdown format.
It recognizes file changes and only translates the modified files.
The translated Markdown content is editable; if you modify the original text and translate it again, manually edited translations will not be overwritten (as long as the original text has not been changed).
* [i18n.site : MarkDown Multi-language Static Site Generator](https://i18n.site/i18n.site)
Optimized for a better reading experience
