clap_complete: How to set nospace for zsh?

[fioncat]

Hi, I am trying the clap_complete unstable-dynamic feature.

When I complete somethings, how to set -S '' flag? I need to use this in some scenes.

We don't support this yet; it is being tracked in #5587.

It would help if you posted your use case.

Thank you for your reply! My current use case is similar to zsh’s built-in directory completion: if completion items end with “/”, then need to add -S ''.

For example:

fn custom_completer(current: &std::ffi::OsStr) -> Vec<CompletionCandidate> {
    if current.to_string_lossy().starts_with("dir0/") {
        // Should not add `nospace` flag
        return vec![
            CompletionCandidate::new("dir0/file0"),
            CompletionCandidate::new("dir0/file1"),
        ];
    }

    // Should add `nospace` flag
    vec![
        CompletionCandidate::new("dir0/"),
        CompletionCandidate::new("dir1/"),
    ]
}

Maybe add a return flag to contol this?

struct CompletionCandidates {
    items: Vec<CompletionCandidate>,
    no_space: bool,
}

fn custom_completer(current: &std::ffi::OsStr) -> CompletionCandidates {
    if current.to_string_lossy().starts_with("dir0/") {
        // Should not add `nospace` flag
        return CompletionCandidates {
            items: vec![
                CompletionCandidate::new("dir0/file0"),
                CompletionCandidate::new("dir0/file1"),
            ],
            no_space: false,
        };
    }

    // Should add `nospace` flag
    CompletionCandidates {
        items: vec![
            CompletionCandidate::new("dir0/"),
            CompletionCandidate::new("dir1/"),
        ],
        no_space: true,
    }
}
