Command Line Options
The ring language takes source code file (.ring) or the object file (.ringo) as input to execute, also the language provide other options like
| Option | Description |
|---|---|
| -tokens | Print a list of tokens in the source code file |
| -rules | Print grammar rules applied on the tokens |
| -ic | Print the intermediate byte code (before execution) |
| -icfinal | Print the final byte code (after execution) |
| -cgi | Print http response header before error messages |
| -norun | Don’t run the program after compiling |
| -ins | Print instruction operation code before execution |
| -performance | Print clock before and after program execution |
| -go | Generate Object File |
| -w | Display Warnings |
Printing Tokens
Example:
Func Main
See "Hello World" + nl
for x = 1 to 10
see x + nl
next
test()
func test
see "welcome" + nl
o1 = new point { x=10 y=20 z=30 }
see o1
class point x y z
Command:
ring test.ring -tokens -norun
Output:

Generate Object File
You can generate object file (.ringo) from your source code file (.ring) using -go option
Tip
You will get one object file to use for distributing/running your application which may contains one or many ring source files that you can keep or distribute based on the application (commercial or open source).
Command:
ring test.ring -go
To run the compiled object file
ring test.ringo
