7.1 – Iterators and Closures - Any iterator needs to keep some state between successive calls, so that it knows where it is and how to proceed from there. Closures provide an excellent
7.3 – Stateless Iterators - As the name implies, a stateless iterator is an iterator that does not keep any state by itself. Therefore, we may use the same stateless iterator in multiple loops,
7.5 – True Iterators - The name "iterator" is a little misleading, because our iterators do not iterate: What iterates is the for loop. Iterators only provide the successive values for the
Lua Iterators - Lua Iterators - Learn Lua Programming Language in simple and easy steps starting from basic to advanced concepts with examples including Overview,
lua-users wiki: Iterators Tutorial - We can write our own iterators to be called by the for statement. The following Lua pseudo-code describes how the for statement works with
lua-users wiki: For Tutorial - One can be used to iterate through a numeric progression and the other can be used to iterate over functions called iterators. The for statement
Lua Closures and Iterators - Except we're not calling it maker() this time, because the Lua convention is to call the iterator maker what the iterator produces -- pairs(), ipairs(), or in this case
Lua - The Lua standard library provides two iterator functions that can be used with a for loop to traverse key-value pairs within tables. To iterate over a sequence table
Lua - lua documentation: Stateless Iterators. A stateless iterator uses only the generic for loop's control variable and invariant state to compute the iteration value.
Lua, custom iterator - proper way to define? - local function phones(d) local cn, c, tn, t, i return function() local a repeat if tn then a, i = t[i], i+1 if not a then i, tn, t = 1, next(c, tn) end else cn,
lua for loop example
loop - First, all three expressions are evaluated once, before the loop starts. For instance, in the first example, f(x) is called only once. Second, the control variable is a
Lua for Loop - Lua for Loop - Learn Lua Programming Language in simple and easy steps starting from basic to advanced concepts with examples including Overview,
Lua Loops - In general, statements are executed sequentially: the first statement in a function is executed first, followed by the second, and so on. Lua provides the following types of loops to handle looping requirements. Executes a sequence of statements multiple times and abbreviates the
lua-users wiki: Control Structure Tutorial - The if statement lets you run different code based on a condition: for tables, which haven't been introduced yet, but here's an example to give
lua-users wiki: For Tutorial - One can be used to iterate through a numeric progression and the other can be used to Using the same table as in the example above:.
For Loop on Lua - The for loop declares a local variable that just happens to be called names . table names each element has a key starting from 1, for example:
Loops - A Lua tutorial about 'Loops' be much better to incorporate the condition we're checking for in the if-statement into the loop itself, for example the following:
Lua/Loops - Lua modules based on the Scribunto/Lua extension are stored in resource pages using the Loops are code structures used to repeat statements in scripts.
First steps with Lua - First steps with Lua - Loops. Loops. For-Loop; While-Loop; Repeat-loop; Abortion. Loops. For-Loop. Parameter for the For-command: Initial value; End value
Lua Looping - Looping in Lua: for, while, do-until, iterators. Lua's generic for loop is much more powerful than Perl's foreach because, .. And now for some example code:
