seline

Tool for interactively selecting input lines

se(lect) line(s)

seline is a command line tool for interactively selecting one (or more) lines from stdin and passing them to stdout. It is intended to be composed with other tools.

Installation

Via npm

npm install -g seline

Via yarn

yarn global add seline

CLI Examples

Here are some example applications that I have been using

Select and delete multiple git branches

$ git branch | seline -m | xargs git branch -D

Checking out a recent git branch.

$ git branch --sort=-committerdate | grep -v '*' | seline | xargs git checkout

Select a branch, then select commits to cherry-pick

git branch | seline | xargs git log --oneline | seline -m | awk '{print $1}' | tail -r | xargs git cherry-pick

Programmatic Examples

seline can also be required and used programmatically. Results are returned as a promise.

seline(choices, options)

• choices required; an array of strings that are presented for selection
• options optional; a dict of configuration options

option | type | default | description ---|---|---|--- multiline | boolean | false | enable multiple line selection outputIndex | boolean | false | output line index instead of line hideNumbers | boolean | false | hide selection number prefix preserveOrder | boolean | false | output lines in order of selection compact | boolean | false | separate options by tabs instead of newlines skipBlanks | boolean | false | selection cursor skips empty lines skipChar | char | null | selection cursor skips line starting with char noColor | boolean | false | use extra characters to show state instead of color lockLines | boolean | false | prevent reordering lines with u and d

const seline = require('seline');

async function main() {
  const results = await seline(['a', 'b', 'c'], { multiline: true });
}
