Conventions

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "We can include other contexts through the use of the include directive."

A block of code is set as follows:

local sum_of_numbers = 0
local iterations = 3
for i=1,iterations do
  sum_of_numbers = sum_of_numbers + 1/iterations
  print(("%f"):format(sum_of_numbers))
end
-- is the result equal to 1?
print("Sum equals to 1?", sum_of_numbers == 1)

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

gl.Begin(gl_enum.GL_LINES)
  -- A
  gl.Color4f(1, 0, 0, 1)
  gl.Vertex3f(-0.5, -0.5, 0)
  -- B
  gl.Color4f(0, 1, 0, 1)
  gl.Vertex3f(0.5, -0.5, 0)
  -- C
  gl.Color4f(0, 0, 1, 1)
  gl.Vertex3f(0.5, 0.5, 0)
  -- D
  gl.Color4f(1, 1, 0, 1)
  gl.Vertex3f(-0.5, 0.5, 0)
gl.End()

Any command-line input or output is written as follows:

mkdir luagl/build
cd luagl/build
cmake ..

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "You can validate settings by pressing the Configure button"

Note

Warnings or important notes appear in a box like this.
