replaceString?

[Ed! 13]

I needed a function to replace a certain set of characters within a string. I found BIS_fnc_splitString and BIS_fnc_trimString etc. but not a replaceString. So I made it myself, but usually there is always somebody afterwards posting a simple 1 liner that does everything I tried in my 100 lines - and Im here asking for it.

This is what I got

strings_replace = 
{
_string = _this select 0;
_replace = _this select 1;
_replaceWith = _this select 2;
_strar = toArray (_string);
_replaceAr = toArray (_replace);
_replaceWithAr = toArray (_replaceWith);
_newStrAr = [];
for[{_i = 0}, {_i < count(_strar)}, {_i = _i + 1}] do
{
	if((_strar select _i) == (_replaceAr select 0)) then
	{
		_match = true;
		for[{_k = 0}, {((_k + _i) < count(_strar)) && (_k < count(_replaceAr))}, {_k = _k + 1}] do
		{
			if((_strar select (_k + _i)) != (_replaceAr select _k)) then 
			{
				_match = false;
			};
		};
		if(_match) then
		{
			for[{_j = 0}, {_j < count(_replaceWithAr)}, {_j = _j + 1}] do
			{
				_newStrAr = _newStrAr + [_replaceWithAr select _j];
			};
			_i = _i + count(_replaceAr) - 1;
		}
		else
		{
			_newStrAr = _newStrAr + [_strar select _i];
		};
	}
	else
	{
		_newStrAr = _newStrAr + [_strar select _i];
	};
};
toString (_newStrAr);
};

Or did somebody out there make a whole library of string manipulation functions for us to use?

You can already use substring functionality:

Made with KK's SQF to BBCode Converter

That's so much shorter than what I wasted my time on :P. Another question off topic now, what are the benefits when using private [...] in this particular example? It would work without the private [...] too? Is there some kind of performance gain or formality tied to it?

[killzone_kid 1332]

private limits and isolates variable in scope it was defined in

My solution is exactly the same as KK's...

DE_replaceSection =
{
_input = _this select 0;
_replace = _this select 1;
_replaceWith = _this select 2;
_output = "input not found";

_location = _input find _replace;

if (_location > -1) then
{
	_front = _input select [0, _location];
	_end = _input select [_location + (count _replace)];
	_output = format ["%1%2%3", _front, _replaceWith, _end];
};
_output;
};

hint str (["Hello! My name is DreadedEntity", "DreadedEntity", "Ed"] call DE_replaceSection);

This is great, thanks!
