Sample Lua Programs

Primer

It is highly recommended that the lua programming manuals be studied to understand the syntax and structure of lua programs. To assist, the following are some pointers based on a beginner's experience in programming in lua for eccoext:

• there is no error trapping or reporting, if the code fails generally nothing happens and there is no feedback given as to the reason for the failure;
• a typical error can be the omission of the "then" as part of the "if" statement or similar typographical errors;
• take care to distinguish between the lua code contained in rules and programs. The program uses the lua 5.1 code whereas the rules use the slang interpretation of lua;
• some of these samples are written as eccoext rules and others as functions. The only difference is that the functions start with a name and end in a corresponding 'end'. To change the scripts simply add the function name and the closing end statement: it is a common mistake to leave off the closing end statement.

Most programs may be tested using the eccoext evaluator prior to implementing it into a function. The evaluator is very useful for debugging of sections of code to activate in eccoext use CTRL ALT K.
