luapp has been updated to 1.1.0!, new additions:

• –pp:ifdef definition: Similar to a ignore zone, but ignores if "definition" is not defined
• –pp:ifndef definition: Reverse of "ifdef"
• –pp:if "lua expression": Similar to a ignore zone but ignores if "lua expression" returns false
• –pp:ifn "lua expression": Reverse of "if"
• –pp:else: Reverses a ignore zone.
• Fixed preprocessor commands running on ignore zones.

Here is a example of the ifs

--pp:if 1 == 1
print("1 equals 1!")
--pp:ignoreend

--pp:define DO_PRINT_THAT true

--pp:ifdef DO_PRINT_THAT
print("dpt is defined")
--pp:ignoreend

--yes, ifs also allow the defines with the lua code.

--pp:if DO_PRINT_THAT
print("dpt on")
--pp:else
print("dpt off")
--pp:ignoreend

luapp has been updated to 1.2.0, which now includes:

• The –pp:include command will now look at the following directories for includeable files:

[indent=2]/etc/luapp/include[/indent]
[indent=2]Current directory[/indent]
[indent=2]Root of the filesystem[/indent]

/etc/luapp/include is for global includes that you can redistribute with your API, current directory was the default and the root of the filesystem is just an extra.

luapp will (with a optional setting) now work with the official lua5.1 cli so you can use it for non-Computercraft programs!

luapp has been updated to 1.3.0, changelog here
