= loadstring (X)Return F ()End ))) --> Sin (3) = 0.1411200080598672; 2 ^ 5 = 32 The first match is "$ [math. Sin (3)]", and the corresponding capture is "[math. Sin (3)]". Call string. sub to remove the square brackets at the beginning and end,Therefore, the string to be loaded and executed is "Return math. Sin (3)", and the matching condition of "$ [2 ^ 5]" is similar.We often need to use string. gsub to traverse strings, but we are not interested in the returned results. For example, we colle

Table Basically, this section is about document translation. I don't plan to write examples. The reason is explained at the end. Table means that you can write any style table. How can any style tables be recognized and executed by fitnesse? And how to display the execution results? Let's take a look. The basic idea of the above tables is to either determine the method name (Decision Table) by the header, or fix the method name (Dynamic Decision Table, query table ); you can also use some iden

. When performing the addition operation, lua first checks whether A has a retriable and whether the _ add domain exists in the retriable. If yes, it calls the statement. Otherwise, it checks the condition of B (which is the same as that of ), if no addition operation exists, the default addition operation is called, and the table does not define the default addition operation. An error is reported. -- Define two tablesA = {5, 6}B = {7, 8}-- Use C for retriableC = {}-- Redefinition of addition

In java, it is easy to use regular expressions to split a string. The following uses Lua to implement the spilt function. Method 1: Local spilt = function (str, pattern) local ret = {}; local _ pattern = "[^ ".. pattern .. "] +"; for s in string. gfind (str, _ pattern) dotable. insert (ret, s); endreturn ret; end Method 2: Local spilt = function (str, pattern) local ret = {} string. gsub (str, "[^ ".. pattern .. "] +", function (item) tabl
