Using the Command-line Interface 3-3
Now, the error is on line 3 or, you can include the input file using an include.
3.2 RL Command-Line Options
3.3 RL Command-Line Built-in Commands
This section lists commands that are implemented by the RL command-line interface these commands are not part of RL. Thus, these commands cannot appear in blocks
or be included rulesets.
3.3.1 Clear Command
Discard the current RuleSession object and allocate a new one. The effect is that all rules, variables, classes, and functions are discarded.
Instead of using clear; to restart a command-line you can also type exit; and then reissue the Java command to start another command-line.
Table 3–1 RL Command-Line Options
Flag Description
–i Read rulesets from the file named by the next argument, instead of from the
default, System.in. For example,
-i myInput.rl Note: the command-line segments its input into blocks and then feeds each
block to the interpreter. If the file myInput.rl does not include a closing brace or semicolon at the end, then, no error is raised because the command
line waits for additional input before it does a full parse of the block. Thus, there are cases where an incomplete input file supplied using the –i option
could run and execute the valid part of the code from the file myInput.rl, and exit, while still waiting for command line input.
–c Executes the next argument as the first RL command, then start reading
input. This option is useful to include a file of settings and functions for debugging.
For example, -c include file:debugSettings.rl;
If you do not want to read from the input after executing the command, include exit; after the command.
For example, -c include file:script.rl; exit;
–p Sets the next argument as the prompt string.
For example, -p RL
-o Specifies where to write output from println, watch, and show to the file
named by the next argument, instead of to System.out. For example:
–o debug.log –v
Print version information.

3.3.2 Exit Command
Exit the command-line interface. The command-line interface also exits when end-of-file is reached on its input.
