tesseract nao esta instalado

Error message

tesseract nao esta instalado

What it means

`ocr::run` calls `locate()` which searches the system for the `tesseract` binary (first via the dependency finder, then a fixed list of standard install paths). If no executable is found, it aborts with 'tesseract nao esta instalado'. The app shells out to the system Tesseract instead of bundling it, so OCR is simply unavailable when the binary is not on disk.

Solutions

1. Install tesseract with the documented command: `brew install tesseract tesseract-lang` (macOS), `sudo apt install tesseract-ocr tesseract-ocr-por` (Linux), or `winget install UB-Mannheim.TesseractOCR` (Windows).
2. Verify `which tesseract` / `where tesseract` resolves; if not, symlink the binary into one of the probed paths (e.g. /usr/local/bin).
3. Call the status() endpoint first (it returns `installed` and an `install_hint`) and surface the hint to the user instead of calling run().

Example fix

// before
let results = ocr::run(&[path], "eng", progress).await?;
// after
if !ocr::status().await.installed {
    return Err(anyhow!("instale o tesseract: {}", ocr::status().await.install_hint));
}
let results = ocr::run(&[path], "eng", progress).await?;

let status = ocr::status().await;
if !status.installed {
    return Err(anyhow!("OCR indisponível: instale com {}", status.install_hint));
}

async fn tesseract_available() -> bool {
    ocr::status().await.installed
}

match ocr::run(&inputs, langs, progress).await {
    Ok(results) => results,
    Err(e) if e.to_string().contains("nao esta instalado") => {
        eprintln!("instale o tesseract primeiro");
        Vec::new()
    }
    Err(e) => return Err(e),
}

When it happens

Trigger: Calling `run`, or any of its callers share_file/share_url/share_text/ping/refresh, on a machine where tesseract is not installed or is installed outside the probed paths (`/opt/homebrew/bin`, `/usr/local/bin`, `/usr/bin`, `C:\Program Files\Tesseract-OCR\`).

Common situations: Fresh dev machines or CI containers without tesseract; non-standard installs (e.g. custom prefix, snap, Homebrew on Apple Silicon vs Intel mismatches handled only for the two homebrew paths); Windows installs via other package managers that don't put tesseract.exe in Program Files.
