Package Exports
- printf
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (printf) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

A complete implementation of sprintf and printf for Node. The code is
strongly inspired by the one availabe in the Dojo Toolkit.
Usage
sprintf
var printf = require('printf');
var string = printf(format, args...);printf
var printf = require('printf');
printf(write_stream, format, args...);Exemples
var printf = require('printf');Flag: (space)
assert.eql(' -42', printf('% 5d', -42));Flag: +
assert.eql(' +42', printf('%+5d', 42));Flag: 0
assert.eql('00042', printf('%05d', 42));Flag: -
assert.eql('42 ', printf('%-5d', 42));Precision
assert.eql('42.90', printf('%.2f', 42.8952));
assert.eql('042.90', printf('%06.2f', 42.8952));Bases
assert.eql('\x7f', printf('%c', 0x7f));Mapping
assert.eql('Hot Pocket', printf('%1$s %2$s', 'Hot', 'Pocket'));
assert.eql('Hot Pocket', printf('%(temperature)s %(crevace)s', {
temperature: 'Hot',
crevace: 'Pocket'
}));Positionals
assert.eql(' foo', printf('%*s', 'foo', 4));
assert.eql(' 3.14', printf('%*.*f', 3.14159265, 10, 2));
assert.eql('0000003.14', printf('%0*.*f', 3.14159265, 10, 2));
assert.eql('3.14 ', printf('%-*.*f', 3.14159265, 10, 2));Miscellaneous
assert.eql('+hello+', printf('+%s+', 'hello'));
assert.eql('+10+', printf('+%d+', 10));
assert.eql('a', printf('%c', 'a'));
assert.eql('"', printf('%c', 34));
assert.eql('$', printf('%c", 36));
assert.eql('10', printf('%d', 10));Human readable output with util.inspect
assert.eql("Debug: { hello: 'Node' }", prinf('Debug: %O', {hello: 'Node'});Installing
