The one-page guide to Lua: usage, examples, links, snippets, and more. This information was written for Lua, pre v4.0 -- Nick Trout. Assertions Using the standard assert function with a non-trivial message expression will negatively impact script performance. The reason is that the message expression is evaluated even when the assertion is true.

assertion/modifiers that are Lua keywords (true, false, nil, function, and not) cannot be used using '.' chaining because that results in compilation errors. Instead chain using '_' (underscore) or use one or more capitals in the reserved word (see code examples above), whatever your coding style prefers local ret, data = pcall(the_function) assert(ret, "Error: "..data) -- use data from here on. The problem is that the assert message is evaluated even in case of success, so when the call succeeds Lua complains about concatenating a string with a table. Aliases: assert_nil(), assertIsNil(), assert_is_nil() Assert that a given value is nil. assertNotNil (value) ¶ Aliases: assert_not_nil(), assertNotIsNil(), assert_not_is_nil() Assert that a given value is not nil. Lua coercion rules are applied so that values like 0, "", false all validate the assertion.

file = assert(io.open("no-file", "r")) --> stdin:1: no-file: No such file or directory Among many other things, a Lua-like assertmacro can be made that checks that a condition is true, and if it's not, an error is raised, in such a way that by just changing a definition, all assert's in the code can be instantly gone, resulting in no code generated for them. And if the assertion passes, the second parameter (the error message to local f = assert(io.open(filename, mode)) If the open fails, the error message goes as the second argument to assert, which then shows the message.

The reason is that the message expression is evaluated even when the assertion is true. For example in assert(x <= x_max, "exceeded maximum ("..x_max..")") describe("some assertions", function() it("tests positive assertions", function() assert.is_true(true) -- Lua keyword chained with _ assert.True(true) -- Lua keyword using a capital assert.are.equal(1, 1) assert.has.errors(function() error("this should fail") end) end) it("tests negative assertions", function() assert.is_not_true(false) assert.are_not.equals(1, "1") assert.has_no.errors(function() end) end) end) According to the Lua5(beta) manual "assert" is equivalent to: function assert (v, m) if not v then error(m or "assertion failed!") end return v end so: a,b,c = assert( f() ) would be doomed to failure (as 'b' and 'c' would never be assigned) :-(. assert (loadstring (content)) () end) RAW Paste Data.

The program must support a command-line interface. There is the overhead of starting up the program, so this method is typically not so suitable if you need to call the code, say, thousands of times per second. Lua stores strings as const char* null-terminated strings.
