This will add new lines and indentation between table items. If false, format everything on one line. The default is false. tabs: If true, indent with tabs; otherwise, indent with spaces. The default is true. This only has an effect if pretty is true. spaces: The number of spaces to indent with, if tabs is false. The default is 4.
Contains a functions to help debug the lua modules.It allows to collect and view the values of several variables and/or points in your lua program, from a module (which is usual) or in several modules (which are required from the main module).
Only false and nil are false. Even "" is true. Tables can have both numeric and string entries. The two don't overlap. t [1] is distinct from t ["1"]. Uninitialized variables and nonexistent fields in tables are nil. or and and both have shortcut evaluation. = is assignment, == is equality comparison. not is boolean negation, but ~= is ...
Demo lines 2 and 3 by Johnuniq above show this effect. Line 4 still has the prefixed space, because by the addition of a character (|), the prefixed space has become an internal space and so is not affected by trimming. {} shows spaces with parameter 1 only because that is the only parameter not #if-ed in code.
A tactic, for dealing with older bugs, is to plan to run special extra test data to activate code areas, or show debug-display output, where new Lua script might be added, to provide a sanity check that the affected areas are functioning soundly, before adding too much new, detailed logic.
Most functions in the module have a version for Lua and a version for #invoke. It is possible to use the #invoke functions from other Lua modules, but using the Lua functions has the advantage that you do not need to access a Lua frame object. Lua functions are preceded by _, whereas #invoke functions are not.
