Now let’s make use of the insert function that takes three arguments, the third argument (or actually the second one) is the position(index), where we want to insert our element. Now when we iterate over the array using the generic for we should see all the values printing to the terminal. This is the online version of the first edition of the book Programming in Lua, a detailed and authoritative introduction to all aspects of Lua programming written by Luas chief architect. In the above example, I am calling the insert function three times to insert values 11, 12 and 13 into our array. Programming in Lua (first edition) contents luacreatetable -0, +1, m void luacreatetable (luaState L, int narr, int nrec) Creates a new empty table and pushes it onto the stack. Nothing fancy is happening in the above code, now let’s say we want to insert an element into the above array, the approach is to make use of the insert function that Lua library provides us. Consider the example shown below −įor i,v in ipairs(a) do print(v) end Output 1 Let’s consider a simple example where we are printing all the values present in an array. In the above example, the x represents the table identifier, the pos represents the position at which we want to insert the element at, and lastly the element denotes the value that we want to insert. Let’s explore different examples of the insert function. If there are three arguments passed to the insert function then the second argument denotes the position in the table where we want to insert the element at. The insert function usually takes two arguments, the first argument is usually the name of the table from which we want to insert the element to, and the second argument is the element that we want to insert. In Lua, the table library provides functions to insert elements into the table.

There are cases when we want to insert elements into a table. how to append to a table in lua how to make a table insert function for lua lua tabke add insert function in lua add new value in table lua add field to table lua table.
