Writing and Running Lua Code

You can use the Zeus IDE to write and execute Lua code.

Here is a simple example:

1) Create a c:\temp\test.lua file using the Lua code shown below:

Code: Select all

printf = function(s,...)
           return io.write(s:format(...))

printf("Hello from %s on %s\n", _VERSION,
2) Use the Compiler, Compile menu to syntax check the Lua code.

3) To run the code use the Macros, Execute 'test.lua' menu and the following output will be captured inside Zeus:

Code: Select all

Checking Lua Code for Errors

As mention earlier the IDE can be used to check the Lua code for syntax errors.

For example consider this piece of code which contains a Lua syntax error:

Code: Select all

function Test(value)
    if (value == 0)
This code can be syntax checked using the Zeus Compiler, Compile menu which when run reports the following error:

Code: Select all

luac52.exe: D:\Temp\test.lua:3: 'then' expected near 'return'
