Tokenize a string into an array of string parts and format identifier objects.

Installation

npm install @stdlib/string-base-format-tokenize

Usage

var formatTokenize = require( '@stdlib/string-base-format-tokenize' );

formatTokenize( str )

Tokenizes a string into an array of string parts and format identifier objects.

var str = 'Hello, %s! My name is %s.';

The format identifier objects have the following properties:

flags	format flags (string with any of '0', ' ', '+', '-', '#')
width	minimum field width (integer or '*')
precision	precision (integer or '*')
mapping	positional mapping from format specifier to argument index

Examples

var formatTokenize = require( '@stdlib/string-base-format-tokenize' );

var out = formatTokenize( 'Hello %s!' );
// returns [ 'Hello ', {...}, '!' ]

out = formatTokenize( 'Pi: ~%.2f' );
// returns [ 'Pi: ~', {...} ]

out = formatTokenize( 'Multiple flags: %#+s' );
// returns [ 'Foo ', {...} ]
