What causes "escolha a pasta de destino" in tonhowtf/omniget?

Set opts.dest to a valid directory path before calling run.

escolha a pasta de destino

Error message

escolha a pasta de destino

What it means

Thrown at the start of the merge tool's synchronous run() when opts.dest is blank or whitespace-only. The merge tool writes its merged output files into the destination directory, so it requires one; the check happens before files are collected.

Solutions

Set opts.dest to a valid directory path before calling run.
Validate dest non-empty in the UI/config layer before invoking the tool.
Trim the input and reject empties early with a clearer message.

Example fix

// before
let opts = merge::Options { dest: " ".into(), .. };
merge::run(&opts, &p)?;
// after
let dest = "~/merged".trim();
assert!(!dest.is_empty());
let opts = merge::Options { dest: dest.to_string(), .. };
merge::run(&opts, &p)?;

Defensive patterns

Strategy: validation

Validate before calling

if opts.dest.trim().is_empty() {
    return Err(anyhow!("dest é obrigatório: informe a pasta de saída do merge"));
}
std::fs::create_dir_all(opts.dest.trim())?;

Type guard

fn has_dest(opts: &Options) -> bool {
    !opts.dest.trim().is_empty()
}

Try / catch

match merge::run(&opts, &p) {
    Err(e) if e.to_string().contains("pasta de destino") => eprintln!("escolha a pasta de destino antes de mesclar"),
    other => other?,
}

Prevention

Require dest in the merge form before submitting
Trim whitespace when building Options
Default dest to a known output directory
Pre-create the destination directory in setup

When it happens

Trigger: Calling run(&opts, &p) with opts.dest set to "" or only whitespace.

Common situations: Merge destination field left empty in the UI; config missing the dest key; default Options constructed with dest: String::new(); whitespace-only paste.
