Ghostscript não encontrado nesta máquina

Error message

Ghostscript não encontrado nesta máquina

What it means

Validation error from pdf_repair::run: the caller requested mode "gs" (Ghostscript-based repair) but super::pdf::find_gs() could not locate a Ghostscript executable on this machine. The library refuses to proceed rather than silently falling back to another method.

Solutions

1. Install Ghostscript and ensure the executable is on PATH (`gs --version` must succeed)
2. On Windows, install Ghostscript and add its bin dir (gswin64c.exe) to PATH, or set whatever env/override find_gs honors
3. Use mode "rebuild" instead, which needs no Ghostscript
4. In CI/Docker, add ghostscript to the image before running the tool

Example fix

// before
pdf_repair::run(RepairOptions { mode: "gs".into(), ..opts }, progress).await?;
// after
if super::pdf::find_gs().await.is_none() {
    eprintln!("Ghostscript ausente; usando modo rebuild");
    opts.mode = "rebuild".into();
}
pdf_repair::run(opts, progress).await?;

// Rust: resolve Ghostscript before choosing the mode
let gs_available = super::pdf::find_gs().await.is_some();
if opts.mode == "gs" && !gs_available {
    eprintln!("Ghostscript ausente; caindo para modo rebuild");
    opts.mode = "rebuild".into();
}

fn gs_mode_supported(mode: &str, gs: &Option<std::path::PathBuf>) -> bool {
    mode != "gs" || gs.is_some()
}

match pdf_repair::run(opts, progress).await {
    Err(e) if e.to_string().contains("Ghostscript não encontrado") => {
        opts.mode = "rebuild".into();
        pdf_repair::run(opts, progress).await
    }
    other => other,
}

When it happens

Trigger: Calling run(RepairOptions { mode: "gs", .. }) on a machine where Ghostscript is not installed, not on PATH, or installed under a binary name find_gs doesn't probe (e.g. gswin64c.exe on Windows, or a custom install prefix).

Common situations: Fresh dev machine or CI container without the ghostscript package; macOS after a partial Homebrew cleanup; Windows where only the Ghostscript GUI is installed and gs/gswin64c isn't on PATH; Docker image built without `apt-get install ghostscript`.
