String (API)

2012-12-07T03:24:29Z

GopherAtl: Undo revision 4703 by 46.231.129.69 (talk)

The string API is a default Lua 5.1 API as defined [http://www.lua.org/manual/5.1/manual.html#5.4 here]. Please list any non-working functions below.

==Non-Working Functions==

===string.gmatch(string, pattern)===

Using any quantifier other than + will cause it to hang if that quantifier applies to the whole pattern and that pattern does not match the whole string.

Examples:
<pre>
"abcdef":gmatch("%a*") -- Works
"abc=def":gmatch("%a*") -- Hang
"abc=def":gmatch("%a.*") -- Works
"abc=def":gmatch("[%a.]*") -- Hang
"abc=def":gmatch("[^=]*") -- Hang
"abc=def":gmatch("([^=]*)=?") -- Works (Note: This produces the same result as the above pattern should)
"abcdef":gmatch("[^=]*") -- Works
"abc=def":gmatch("[^=]*=") -- Works
</pre>

===string.sub / string.find ===

Both string.sub and string.find work on their own, but calling string.find on a string returned by string.sub will return the index of the character in the original string, not the sub string you are referencing.

Example:
<pre>
local testString = "This is a sample string";
local testSubString = string.sub(testString,5);

local indexOfSample = string.find(testSubString,"sample");
</pre>

indexOfSample is returned 11 instead of the expected 7

Concatenating a blank string onto the end of the string causes new memory to be allocated and works properly again

<pre>
local testString = "This is a sample string";
local testSubString = string.sub(testString,5);

local indexOfSample = string.find(testSubString.."","sample");
</pre>

This is also a problem with using string.find on command line arguments, as this returns the index in the full command path instead of the specific argument.

Turtle.drop

GopherAtl: adding notes on dropDown and dropUp, and use with furnaces

{{lowercase}}
{{Function
|name=turtle.drop
|args=count
|returns=true if an item was dropped; false otherwise.
|api=turtle
|addon=ComputerCraft
|desc=Drops all items in the selected slot, or if [count] is specified, drops that many items.
If the space in front of the turtle does not contain a chest, the items are dropped into that space.
If the space in front of the turtle contains a chest, the items are dropped into that chest.
The items will be placed in the first available slot, starting at the top left, moving right and then down.

turtle.dropUp and turtle.dropDown are also available, and useful for loading furnaces; dropUp when below a furnace will load the items as fuel in the furnace's bottom slot, while dropDown when below will load the top slot for smelting.
