Question 1

How do I print bold red error messages with bunt?

Accepted Answer

Use the bunt::eprintln! macro with style tags, e.g., bunt::eprintln!("{$red+bold}Error: Something went wrong{/$}"). This outputs to stderr with cross-platform color support, making it ideal for CLI tools.

Question 2

Bunt vs termcolor: which is better for terminal colors in Rust?

Accepted Answer

Bunt is a convenience wrapper over termcolor, offering a simpler macro-based API. If you prefer direct control and don't mind verbosity, use termcolor; choose Bunt for quicker, more readable code with inline styling.

Question 3

Does bunt work on older Windows systems like Command Prompt?

Accepted Answer

Yes, because it's built on termcolor, which uses Windows console APIs for color support. It should work consistently across Command Prompt, PowerShell, and modern terminals.

Question 4

How to style multiple arguments in a single bunt macro call?

Accepted Answer

Use the {[style]...} syntax for each argument, e.g., bunt::println!("Data: {[green]:?}, count: {[cyan]}", vec, len). This styles formatted outputs individually, as demonstrated in the README.

Question 5

Can I use bunt in non-blocking async applications?

Accepted Answer

Bunt's macros are synchronous and write directly to stdout/stderr. In async contexts, you may need to buffer output or use it in blocking sections, as it doesn't provide async-native APIs.

Question 6

How to disable colors when output is piped to a file?

Accepted Answer

Bunt relies on termcolor's auto-detection, which disables colors for non-TTY outputs. For manual control, you can access termcolor's WriteColor trait, but this adds complexity compared to simpler libraries.
