Show tesseract and leptonica version function?

[kvnxiao]

Does there currently exist a function that can fetch and show the currently used version of tesseract and leptonica? If not, this would be a great addition. I am using leptess in a GUI application and would like to be able to show this information in the "About" option popup.

It would be great if they could be included here as a wrapper to unsafe C_str conversion calls so that I don't have to explicitly declare dependencies on tesseract-sys + leptonica-sys and do:

unsafe {
    let tesseract_ver = CStr::from_ptr(tesseract_sys::TessVersion());
    let leptonica_ver = CStr::from_ptr(leptonica_sys::getLeptonicaVersion());
    let leptonica_libs_ver = CStr::from_ptr(leptonica_sys::getImagelibVersions());
    // ...
}

I don't think so, PRs welcome :)

leptonica-plumbing 0.6.0 and tesseract-plumbing 0.7.1 have both been published to support this

Thanks! Will the Cargo.toml file here need to be updated to set tesseract-plumbing dependency version as ~0.7?

It depends.

If you want to use the methods directly from tesseract-plumbing then you can add the dependency to your app.

If you want to add the methods to leptess, you will need to update leptess's dependencies (and add version methods).

Thanks, I think we can leave it as is like this as part of the *-plumbing repositories.
