How can I customize the required error message for input.

input.is_empty() through the validate method is the way.
my bad.

Reopening this discussion as the solution requires initially pressing Backspace multiple times to work properly.

Have you tried this way

let path: String = cliclack::input("Where should we create your project?")
.placeholder("./sparkling-solid")
.validate(|input: &String| {
    if input.is_empty() {
        Err("Please enter a path.")
    } else if !input.starts_with("./") {
        Err("Please enter a relative path")
    } else {
        Ok(())
    }
})
.interact()?;

Sorry for late reply.
I tried.

let output = cliclack::input("Enter video output file or directory")
    .validate_interactively(move |s: &String| {
      let trim_path = s.trim();
      if trim_path.is_empty() {
        return Err(anyhow!("Path cannot be empty"));
      }
      Ok(())
    })
    .interact::<String>()?;

1. press enter without any input -> Input required
2. press space once -> Path cannot be empty
3. press backspace -> Path cannot be empty
4. press enter again -> Input required

@codenoobforreal You mean, you don't like the "Input required" default message? Try adding required(false) to offload validation fully to your validator closure:

let output = cliclack::input("Enter video output file or directory")
    .required(false)
    .validate_interactively(move |s: &String| {
      let trim_path = s.trim();
      if trim_path.is_empty() {
        return Err(anyhow!("Path cannot be empty"));
      }
      Ok(())
    })
    .interact::<String>()?;

@fadeevab Your approach resolved the exact issue I wanted to express but failed to articulate clearly.
