The easiest way to use luna is go to command line (I'm assuming you use Windows) and go to the directory of luna. You probably should also put your lua source there too. Then type
"luna.exe <filename>.lua <filename>.tns"

I use a .bat for speed. My code looks like
cd C:\Graphing Calculator\Nspire\Lua Programming\luna-v0.2b
luna.exe jumper.lua jumper.tnsI usually work on one project at a time, so it's faster just clicking on an icon.

For those of you who are on OS X and are having trouble building Luna, I found out why it won't build. In the Luna's readme, it states you need gcc >=4.5, but apple's gcc is gcc 4.2. Using MacPorts (or Homebrew, Fink), install gcc 4.7 (run "sudo port install gcc47"). Then open up Luna's Makefile with a text editor and change any instances of "gcc" to "/opt/local/bin/gcc-mp-4.7". Cd to the Luna directory in Terminal, and do make "dist luna", and it builds!

CC:=/opt/local/bin/gcc-mp-4.7
CFLAGS:=-W -Wall -m32
LDFLAGS:= -lssl -lz -m32
VPATH := minizip-1.1

OS ?= `uname -s`
ifeq ($(OS),Windows_NT)
  EXEEXT = .exe
else
CFLAGS := $(CFLAGS) -DUSE_FILE32API
LDFLAGS:= $(LDFLAGS) -lcrypto
endif

all: luna$(EXEEXT)

luna$(EXEEXT): luna.o zip.o ioapi.o
/opt/local/bin/gcc-mp-4.7 -o $@ $^ $(LDFLAGS)

dist: clean all
mkdir -p dist/src
rm -f *.o
find . -maxdepth 1 ! -name 'luna$(EXEEXT)' -a ! -name dist -a ! -name . -exec cp -r {} dist/src \;
cp luna$(EXEEXT) *.dll *.txt dist

clean:
rm -rf *.o luna$(EXEEXT) dist

Alternatively, using clang, if you have that installed, should work. Works for me under Linux.

Hi guys!

First I think this program is really cool!  I find it amazing how much you all figured out about this file format!

If I may; I modified the source code a little to add the ability to extract the Problem1.xml out of the .tns file (though it ONLY works with the luna created .tns files).

So for what it is worth here are the source files: https://dl.dropbox.com/s/jh6nww60fha4tb2/luna_src.zip

After you build it you can do this (example in Linux):
./luna pong.lua pong.tns #Can already do this in current luna
./luna pong.tns #Lists files in the tns file
./luna pong.tns Problem1.xml #Extracts Problem1.xml out and saves it as Problem1.xml

Since extracting only works with the luna created .tns file; that unfortunately means if you take the "hello world" XML from http://ndlessly.wordpress.com/2011/09/19/luna-updated-for-third-party-tns-document-generation/ and construct a .tns file out of it and then on the calculator immediately save it; this program is no longer able to extract the Problem1.xml out of it!

I figure this is a good step!  My change was done with full admiration and respect to everyone's work before mine.

My motivation is it would be cool if nTxt could read/write Note files.  As well as for me I'd think I'd like to make a calculator game, for instance, that would use note file(s) for the levels sets, high score table, config, etc.  So instead of the level sets being some sort of file with the extension being .tns that are sent to the calculator; have them be note files that a user could edit.  I know this is unnecessary because a user can already use nTxt to edit files.

At any rate I learned more about tns files!

Thanks Lionel!

That was my first Omnimaga post!  I very much would like to make some amazing things for these devices!  As well as take a more active part in this community!  I'm glad you like my programs!  I intend on making more (and more comprehensive ones too)!

Hey DJ_O,

My future plans of programs on the calculator will be for the TI-nSpire (because of color screen, memory, processor speed)!  In the short run I'll create single player games (some puzzle games, etc)!  In the long run I hope to make multiplayer games that you can play against A.I.s or another player via the link cable!  Such as Battleship, Hearts, Ticket to Ride, etc.  I've made a long that if anybody else wanted to make the same game I'd happily move onto another program.

Oh I always had a fascination with calculators (grew up without video game systems or computer)!  I should probably explain in detail on another topic about myself than this one.  But as a tech enthusiast the calculator (TI-83 at the time) was the coolest piece of technology I had!  I loved seeing the updates on ticalc.org (and others) and will always be a calculator hobbyist!

Hey DJ_O,

Nice!  I love how information has been easy to browse in wikis too!

I'll post, really soon, what I've been working on the last few days (as well as upcoming releases/updates)!

Have a great day!
