Hi all,

Is there a way to trim whitespaces at the beginning of strings, like truncsp()?

str=str.replace(/^\s*/, '');

//include this somewhere...
String.prototype.trim = function() {
return this.replace(/^[\s\r\n]+|[\s\r\n]+$/g, '');
}
String.prototype.ltrin = function() {
return this.replace(/^[\s\r\n]+/g, '');
}
String.prototype.ltrin = function() {
return this.replace(/[\s\r\n]+$/g, '');
}

now you can use yourstring.ltrim()

Thanks Deuce and Tracker1...

I was hoping I wouldn't need to regexp it and it was provided as part of JSOM, however I'll likely implement a function as you guys have provided the regexp for, thanks.

I have a pretty good set of ObjectModelExtensions for JS if you're interested.
As it is, they should all work in synchronet. Most of them are for things that are sometimes surprising aren't *IN* JavaScript's language. Though it's pretty easy to extend/graft any object/class after the fact.

I have stuff for some .toFormat overload methods for String and Date. I've also spent a little time trying to get base2 functioning in Synchronet properly, but that's been a bit of an effort. base.js works without much trouble though. Still need to implement a number formatter for String.toFormat. It does work with dates as-is ex:

var fmt = "This is a string with a date-time of " +
"{dtm:yyyy-MM-dd HH:mm:ss} " +
"as well as another property of {prop2}.";
var fmt2 = "This uses numbered arguments {0} and {1}";

var now = new Date();
var ret = fmt.toFormat({ dtm:now, prop2: 6 });
var ret2 = fmt2.toFormat(now, 5);

I would be interested in taking a look, if you're happy to provide it. Although the JS and Synchronet APIs are decent, some stuff like .trim would be very useful.

return this.replace(/^[\s\r\n]+/g, '');

\s includes \r and \n. The g flag is useless since + is greedy by default and the match is anchored to the start of the string (unless you want multilines, which you don't).

So just replace(/^\s+/, '');

As for the whole string trim function...

return this.replace(/^[\s\r\n]+|[\s\r\n]+$/g, '');

replace(/^\s*(.*?)\s*$/, '$1');

Is a lot better (a single replace, no OR, etc).

Well, you could do it without a regexp, but it would be harder.

Hey Deuce,

... well... regexps are horrid enough... to try to do a regexp without regexps... sounds painful!

Thanks for the regexp pointers in previous reply.
