REJOINDER

rejoinder
/rɪˈdʒɔɪndə/
noun
a reply or response to a question or remark, esp a quick witty one; retort

Rejoinder is a generator of smart, pretty, and organized output on the console for Node/JS scripts, with optimizations for executing shell commands. It leverages colors and the like using the colors package and makes life easier when executing CLI instructions with shelljs. ShellJS and any CLI extensions are not required, however! Check out lib/Echo/EmitStrategy if you're curious :)

Super awesome when paired with inquirer and/or commander!

Also does children's parties.

Note that rejoinder requires Node.js version >=5.x (including ^6) but does NOT depend on use of the --harmony flag!

Installation

npm install rejoinder

If you want support from shelljs (required to use Execute), install that too:

npm install shelljs

Usage and Examples

var rejoinder = require('rejoinder');
var echo = rejoinder.echo;
var execute = rejoinder.execute;

echo.now('output this very important warning to the console with pretty colors'.formatAsWarning());

echo.beVerbose = true;
echo.ifVerbose('Some debug message will appear');
echo.beVerbose = false;
echo.ifVerbose('Some debug message will not appear!');

echo.if(somethingistrue, 'I spit only the truth!'.formatAsSuccess());

echo.now('all', 'my', 'methods', 'are', 'also', 'variadic!');
echo.if(true, 'even', 'this', 'one :)');

echo.separator = '-';
echo.now('changed', 'the', 'game!');

echo.separator = ' ';
echo.prefix = 'Big:Boy:Time:';
echo.usingPredicate(function(str){ return `"${str}"`; }, 'the', 'time', 'for', 'fun and games is', 'over!');

echo.withPrefix('~>', function()
{
    echo.now('or');
    echo.now('is', 'it? I wonder.');
    echo.withPostfix('NO', 'Wait!');
    echo.withPostfix.action("Don't make me bring Execute into this...");
});

echo.beVerbose = true;
execute.now('return 0'); // prints the command and the result thanks to echo.beVerbose!
