Readme

sprint is implementation of sprintf function from C++. If it is ran in Node.js envirnoment then it's used as module, otherwise module inserts sprint() function into global object (usually window).
Usage:
var sprint = require('sprint').sprint;
// Will return "b a"
console.log(sprint('%2$s %1$s', 'a', 'b'));

All standard format placeholders are supported with the exception of %p (lack of pointers in JavaScript) and %n (lack of references in JavaScript).
In addition, following not standard features are supported:
  • n$ - number of the parameter allowing the parameters to be used multiple
times or displayed in different order. It's not in C99, but it's POSIX entension, so support for it is already common.
  • %b and %B - a binary number
  • %D, %U, %O - practially their lowercase variants. Inserted in this
list just because of their usage in Perl's printf() implementation.
For more information, read documentation of sprintf() in other programming languages.
