Lua for premake4 beginners: is 'variable = {"a", "b"}' same thing as 'variable {"a", "b"}'?

Question

In premake we have constructs like files { "**.h", "**.cpp" } would files = { "**.h", "**.cpp" } be same thing?

Answer 1

No. The construct is the same as

files({"**.h", "**.cpp"})

that is, a function call. In general you can leave out the parenthesis if a function is called with a single literal argument:

print "Hello world!"
