escolha o PDF

Error message

escolha o PDF

What it means

Guard in pdf_table::scan: the caller passed an input PDF path that is empty or whitespace-only, so there is nothing to scan for tables. The function returns early instead of attempting to open a bogus path.

Solutions

1. Pass a real path to an existing PDF in Options.input before calling scan
2. Validate/trim the input path at the call site and surface a user-facing 'select a PDF' message instead of invoking the tool
3. Check upstream code for where Options.input is populated (dialog result, CLI arg) — an empty string usually means the selection step was skipped

Example fix

// before
let opts = Options { input: picked_path.unwrap_or_default(), .. };
pdf_table::scan(&opts, &progress)?;
// after
let picked = picked_path.filter(|p| !p.trim().is_empty());
let Some(path) = picked else { anyhow::bail!("escolha o PDF"); };
let opts = Options { input: path, .. };

// Rust: validate before calling scan
fn ensure_pdf_chosen(opts: &pdf_table::Options) -> anyhow::Result<()> {
    if opts.input.trim().is_empty() { anyhow::bail!("escolha o PDF"); }
    let p = std::path::Path::new(opts.input.trim());
    if !p.is_file() { anyhow::bail!("arquivo não existe: {}", opts.input); }
    Ok(())
}

fn has_input(opts: &pdf_table::Options) -> bool {
    !opts.input.trim().is_empty()
}

match pdf_table::scan(&opts, &progress) {
    Err(e) if e.to_string() == "escolha o PDF" => {
        // surface file-picker dialog / usage message to the user
        prompt_user_for_pdf()?;
    }
    other => other?,
}

When it happens

Trigger: Calling scan(&Options { input: "".into() | " ".into(), .. }, progress) — typically because the field was never filled, a form dialog was cancelled, or an empty String defaulted in.

Common situations: Frontend sends an empty input field; config/CLI flag for the PDF omitted; variable holding the path was overwritten with ""; user picked no file but the tool was invoked anyway.
