a little bug fix
String.format("hello {{world}} {{escape}} {{won't escape}} {0} | need
to be 1 with brackets but gets value: {{1}}","value 1","value 2")
won't result the desired output.
i've wrote a function:
String.Format=function (s) {
// © eLad
var args=arguments;
// the next rx matches every string like {#} but not with an escaped {
/ } ({{ / }}).
// nonBracket is a character before a matched {#} which is a part of
the original string and can't be lost. since js doesn't support
negative lookbehinds this character must be saved and concatenated to
the result
s=s.replace(/([^\{])\{([0-9]+)\}(?!\})/g,function
(whole,nonBracket,number) { return nonBracket+args[+number+1]; });
// all escaped { / }
s=s.replace(/\{\{/g,"{").replace(/\}\}/g,"}");
return s;
}
alert(String.Format("arg 0: {0} | arg 1: {1} | escaped text:
{{escaped}} | escaped number: {{1}} | arg 2: {2}","value 0","value
1","value 2"));
