mocheng / template.js
Created February 14, 2011 02:40
Simple template function to replace pattern in string with object properties or function returned value.
/**
* Simple template function.
*
* For each pattern in argument template, it is replaced with actual property from argument data.
* t('{greeting} world', {greeting: 'hello'}) === 'hello world'
*
* Sequence of property in argument data doesn't matter:
* t('{g} {x}', {g: '{o}', o: 'x'})) === '{o} {x}'
* t('{g} {x}', {o: 'x', g: '{o}'})) === '{o} {x}'
