A simple sprintf library for Node.js and the browser.
Majority of the code is from http://www.webtoolkit.info/javascript-sprintf.html
From the site:
Several programming languages implement a sprintf function, to output a formatted string. It originated from the C programming language, printf function. Its a string manipulation function.
This is limited sprintf Javascript implementation. Function returns a string formatted by the usual printf conventions. See below for more details. You must specify the string and how to format the variables in it. Possible format values:
- %% – Returns a percent sign
- %b – Binary number
- %c – The character according to the ASCII value
- %d – Signed decimal number
- %f – Floating-point number
- %o – Octal number
- %s – String
- %x – Hexadecimal number (lowercase letters)
- %X – Hexadecimal number (uppercase letters)
Additional format values. These are placed between the % and the letter (example %.2f):
- + (Forces both + and – in front of numbers. By default, only negative numbers are marked)
- – (Left-justifies the variable value)
- 0 zero will be used for padding the results to the right string size
- [0-9] (Specifies the minimum width held of to the variable value)
- .[0-9] (Specifies the number of decimal digits or maximum string length)
If you plan using UTF-8 encoding in your project don’t forget to set the page encoding to UTF-8 (Content-Type meta tag), and use Javascript UTF-8 utility found on this website.
