Seamlessly integrate, pause, select, and refine your pipeline, enhancing data processing precision. 8 | 9 | # Features 10 | - Interactive Selection: Pause the pipeline's execution to manually select specific lines from the input stream. 11 | - Seamless Integration: Easily integrate the Interactive Line Selector into your existing command-line pipelines. 12 | - Optimized Workflow: Curate data on-the-fly for more accurate and meaningful results. 13 | 14 | # Usage 15 | 16 | Incorporate the Interactive Line Selector into your pipeline: 17 | 18 | 
19 | <command producing input> | lineselect | <subsequent command>
20 |
21 | 22 | Use arrow keys to navigate, press `Space` to select/deselect lines, and press `Enter` to proceed with the selected lines. 23 | 24 | # Example 25 | 26 | Imagine you have a list of files in a directory and you want to selectively remove them using `rm`. Instead of using a complex find command, you can utilize the Interactive Line Selector to streamline the process: 27 | 28 | 
29 | ls | lineselect | xargs rm

If you have ideas for improvements or new features, please feel free to submit a pull request. 52 | 53 | # Acknowledgments 54 | 55 | This project builds upon the fantastic work of the following projects: 56 | 57 | - [Clap](https://github.com/clap-rs/clap) - A full featured, fast Command Line Argument Parser for Rust. 58 | - [Dialoguer](https://github.com/console-rs/dialoguer) - Rust utility library for nice command line prompts and similar things. 59 | - [Colored](https://github.com/colored-rs/colored) - Coloring terminal so simple you already know how to do it! 60 | 61 | ## Previous Implementation 62 | 63 | This idea has been implemented before by [chfritz/lineselect](https://github.com/chfritz/lineselect) using JavaScript. Our project aims to provide an option in Rust with a single binary. 64 | 65 | # License 66 | 67 | This project is licensed under the MIT License - see the [LICENSE](LICENSE) file for details. 68 | -------------------------------------------------------------------------------- /src/main.rs: -------------------------------------------------------------------------------- 1 | use clap::Command; 2 | use colored::Colorize; 3 | use dialoguer::{console::Term, theme::SimpleTheme, MultiSelect}; 4 | use std::io; 5 | 6 | fn cmd() -> clap::Command { 7 | let name = "lineselect"; 8 | 9 | Command::new(name) 10 | .override_usage(format!( 11 | " | {} | ", 12 | name.bold() 13 | )) 14 | .version("0.1.1") 15 | .author("Gilson Urbano ") 16 | .about("Select lines") 17 | } 18 | 19 | fn read_lines(reader: R) -> Vec { 20 | let mut lines = Vec::new(); 21 | 22 | for line in reader.lines() { 23 | match line { 24 | Ok(line) => lines.push(line), 25 | Err(error) => { 26 | eprintln!("Error: {}", error); 27 | break; 28 | } 29 | } 30 | } 31 | 32 | lines 33 | } 34 | 35 | fn main() -> Result<(), Box> { 36 | cmd().get_matches(); 37 | 38 | let stdin = io::stdin(); 39 | 40 | let lines = read_lines(stdin.lock()); 41 | 42 | if let Some(positions) = MultiSelect::with_theme(&SimpleTheme) 43 | .with_prompt(format!("{} {}", "?".red().bold(), "Pick some lines".bold())) 44 | .report(false) 45 | .items(&lines) 46 | .interact_on_opt(&Term::stderr())? 47 | { 48 | positions 49 | .iter() 50 | .for_each(|position| println!("{}", lines[*position])); 51 | } 52 | 53 | Ok(()) 54 | } 55 | 56 | #[test] 57 | fn test_cmd() { 58 | cmd().debug_assert(); 59 | } 60 | 61 | #[test] 62 | fn test_read_lines() { 63 | use std::io::Cursor; 64 | let input = "Line 1\nLine 2\nLine 3\n"; 65 | let reader = Cursor::new(input); 66 | 67 | let lines = read_lines(reader); 68 | 69 | assert_eq!(lines.len(), 3); 70 | assert_eq!(lines[0], "Line 1"); 71 | assert_eq!(lines[1], "Line 2"); 72 | assert_eq!(lines[2], "Line 3"); 73 | } 74 | --------------------------------------------------------------------------------
