optimist 's direct dependencies. Data on all dependencies, including transitive ones, is available via CSV download.Optimist is a lightweight Node.js library designed for option parsing with an argv hash. It is designed to eliminate the complexities often associated with option parsing by simplifying the process down to a simple hash, making it an excellent solution for those who seek extensive --bells and -whistlz of program usage without having to deal with cumbersome optstrings. However, it's worth noting that the package has been deprecated with the maintainers now encouraging the use of the packages such as minimist and yargs for argument parsing needs.
To use Optimist, start by installing the Optimist module via npm (npm install optimist). Once installed, you can require it in your JavaScript file like this: var argv = require('optimist').argv;. You can then use the resulting argv object to access command line arguments using the dot notation, like argv.input. Here's an example usage:
#!/usr/bin/env node
var argv = require('optimist').argv;
if (argv.rif - 5 * argv.xup > 7.138) {
console.log('Buy more riffiwobbles');
} else {
console.log('Sell the xupptumblers');
}
Run this script using the command ./script.js --rif=55 --xup=9.52 and ./script.js --rif=12 --xup=8.1 to see its usage. On top of this, Optimist supports a wide variety of features including short options, booleans, non-hyphenated options, and more.
Optimist's documentation, including methods, usage examples, and other additional features like aliasing, default values, required values, and displaying usage information, can be found on the project's GitHub page at http://github.com/substack/node-optimist.git. Please note that the package is in a deprecated state, it's recommended to consider options like minimist or yargs if starting a new project.
