pyformat

Simple Python-style string formatting for JS

This implements a simple subset of the Python string.format method capabilities. The idea is that you can share a format string between JS and Python.

Installation

npm install pyformat

Usage

var pyformat = require('pyformat')
pyformat(format_string ,args ,kwargs)

format_string is a string with {} substitution blocks, either bare, indexed, or by keyword. args is an array used for indexed substitution. kwargs is an object used for keyword substitution.

The method throws no errors, since this is javascript.

Examples:

console.log(pyformat( 'The {} {} jumped over the {}'
                    , ['brown' ,'fox' ,'foobar']
                    ))
console.log(pyformat( 'The {0} {1} jumped over the {1}'
                    , ['brown' ,'fox' ,'foobar']
                    ))
console.log(pyformat('The {color} {animal} jumped over the {thing}'
                    , [] ,{color: 'brown' ,animal: 'fox' ,thing: 'foobaz'}
                    ))
