[solved] Length of a string ?

[gouxim]

I have a string. How to know its length?

Edit 2: you can use TextLib::Length() since the last update!

Edit: here's how to do it

Code: Select all

#Include "TextLib" as TextLib

Integer manialib_strlen(Text text)
{
	declare length = 0;
	while(TextLib::SubString(text, length,1) != "")
	{
		length = length+1;
	}
	return length;
}

Here's my solution:

Code: Select all

Integer strlen(Text text) {
	for (i, 0, 100000)
		if (TextLib::SubString(text, i, 1) == "") return i;
	return 0;
}

Yes, this solution is crappy, but I don't think there's any other way

I talked to gugli and there's no such function at the moment. Before reading your message I came up with a similar solution, but using a while loop so there's no upper bound for the size:

Code: Select all

#Include "TextLib" as TextLib

Integer manialib_strlen(Text text)
{
	declare length = 0;
	while(TextLib::SubString(text, length,1) != "")
	{
		length = length+1;
	}
	return length;
}

I agree, a while loop is the better solution

then perhaps it would be better to add it, wouldn't it ? a loop with a substring seems a very ugly solution (despite the fact that it seems to be the only one actually)

Well, of course. In fact it's already added. I will try to see if I can slip this in next update.
