While Lua allows the true and false boolean values, wikicode templates can only express boolean values through strings such as "yes", "no", etc. This module processes these kinds of strings and turns them into boolean input for Lua to process. It also returns nil values as nil, to allow for distinctions between nil and false. The module also ...
-- Also returns the value index and a reason when failing. function ValueMatcher. matches (value, matchedValues) return matchValues (value, matchedValues) end--- Matches any value. ValueMatcher. any = createMatcher (function (value) return true end)--- Matches any value but nil.
Removes duplicate values from an array. This function is only designed to work with standard arrays: keys that are not positive integers are ignored, as are all values after the first nil value. (For arrays containing nil values, you can use compressSparseArray first.) The function tries to preserve the order of the array: the earliest non ...
Running your code through an IDE is helpful for its text highlighting features, which can help you quickly spot syntax errors. Any IDE with the ability to install a Lua text highlighting plugin should work. This could be as simple as Notepad++ (with Lua selected from the language menu) or as full-featured as Visual Studio Code.
The module itself must return a Lua table of values. A Lua table is expressed as a list of values separated by commas, within curly braces. When the module is called by #invoke, the function it names (the first argument after |) is looked for in that table. That function, in turn, is expected to return something that can be represented as a string.
For a regular array, with non-nil values from 1 to a given n, its length is exactly that n, the index of its last value. If the array has "holes" (that is, nil values between other non-nil values), then #t can be any of the indices that directly precedes a nil value (that is, it may consider any such nil value as the end of the array).

LuaRocks is a package manager for the Lua programming language that provides a standard format for distributing Lua modules (in a self-contained format called a "rock"), a tool designed to easily manage the installation of rocks, and a server for distributing them. While not included with the Lua distribution, it has been called the "de facto ...
