promkit = "0.10.1"
Features
- Cross-platform support for both UNIX and Windows utilizing crossterm
- Modularized architecture
- promkit-core
- Core functionality for basic terminal operations and pane management
- promkit-widgets
- Various UI components (text, listbox, tree, etc.)
- promkit
- High-level presets and user interfaces
- promkit-derive
- A Derive macro that simplifies interactive form input
- promkit-core
- Rich preset components
- Readline - Text input with auto-completion
- Confirm - Yes/no confirmation prompt
- Password - Password input with masking and validation
- Form - Manage multiple text input fields
- Listbox - Single selection interface from a list
- QuerySelector - Searchable selection interface
- Checkbox - Multiple selection checkbox interface
- Tree - Tree display for hierarchical data like file systems
- JSON - Parse and interactively display JSON data
- Text - Static text display

Projects using promkit
Examples/Demos
promkit provides presets so that users can try prompts immediately without having to build complex components for specific use cases.
Show you commands, code, and actual demo screens for examples that can be executed immediately below.
Readline
Command
cargo run --bin readline --manifest-path examples/readline/Cargo.toml
Code
use promkit::{preset::readline::Readline, suggest::Suggest};
fn main() -> anyhow::Result<()> {
let mut p = Readline::default()
.title("Hi!")
.enable_suggest(Suggest::from_iter([
"apple",
"applet",
"application",
"banana",
]))
.validator(
|text| text.len() > 10,
|text| format!("Length must be over 10 but got {}", text.len()),
)
.prompt()?;
println!("result: {:?}", p.run()?);
Ok(())
}
Confirm
Command
cargo run --manifest-path examples/confirm/Cargo.toml
Code
use promkit::preset::confirm::Confirm;
fn main() -> anyhow::Result<()> {
let mut p = Confirm::new("Do you have a pet?").prompt()?;
println!("result: {:?}", p.run()?);
Ok(())
}
Password
Command
cargo run --manifest-path examples/password/Cargo.toml
Code
use promkit::preset::password::Password;
fn main() -> anyhow::Result<()> {
let mut p = Password::default()
.title("Put your password")
.validator(
|text| 4 < text.len() && text.len() < 10,
|text| format!("Length must be over 4 and within 10 but got {}", text.len()),
)
.prompt()?;
println!("result: {:?}", p.run()?);
Ok(())
}

items
.iter()
.filter(|num| query <= num.parse::<usize>().unwrap_or_default())
.map(|num| num.to_string())
.collect::<Vec<String>>()
})
.unwrap_or(items.clone())
