format method
Replace string pattern consecutively. Patterns are marked with double-curly brackets.
Example:
var template = "My name is {{name}} and I'm {{age}} years old"
sprintf(template, ['Oval', 17]);
Result:
"My name is Oval and I'm 17 years old"
Implementation
String format(List replacements) {
var template = this;
var regExp = RegExp(placeholderPattern);
assert(regExp.allMatches(template).length == replacements.length,
"Template and Replacements length are incompatible");
for (var replacement in replacements) {
template = template.replaceFirst(regExp, replacement.toString());
}
return template;
}
