Copy in your code the functions you want and start using them, that's all ! :-) Please also write in your code/readme something like "[a part of] BetterLuaAPI by Adriweb was used"... Since this is all written in Nspire-Lua, it requires you to run any OS 3.x on your calculator. The latest OS updates are available on TI's Website.

• device table : informations about the user's device (apiversion ? , hasColor ? , isCalc ? , type of calc ? , current language ? )-
• Colors table (can be used for setColor)
• copyTable(table) (copies a table into another)
• deepcopy(table) (deep-copies a table into another)
• test(arg) (returns 1 if arg true or 0 if arg false)
• screenRefresh() same as platform.window:invalidate() but shorter
• pww() same as platform.window:width() but shorter
• pwh() same as platform.window:height() but shorter
• gc:drawPoint(x, y)
• gc:drawCircle(x, y, radius)
• gc:fillCircle(x, y, radius)
• gc:fillGradientCircle(x, y, radius, color1Tbl, color2Tbl)
• gc:fillGradientRect(x, y, w, h, color1Tbl, color2, direction) (direction can be 1 or 2)
• gc:drawCenteredString(str)
• gc:drawXCenteredString(str,y)
• gc:setColor(theColor) (string or table of RGB)
• gc:verticalBar(x)
• gc:horizontalBar(y)
• gc:drawSquare(x,y,l)
• gc:drawRoundRect(x,y,width,height,radius)
• gc:fillRoundRect(x,y,wd,ht,radius)
• gc:clearWindow(theColor)
