Output

Output is to be written to a file specified on the command line. Your interpreter will be invoked with the following command:

generator <input_file_path> <output_file_path>

You should open the file output_file_path and write to it. The output file should be overwritten if it already exists.

Output content is standardized to ensure everyone can pass everyone’s tests. Follow these specifications:

• All generated numbers should be printed on the same line with a single space separating the numbers.

• There must be a new line after each generator’s output.

• There must not be any trailing space after the final number and before the newline.

• There must be an empty line at the end of your output (a result of #2).

Clarification: Empty input should result in empty output. (empty-input)

Example input (3 lines):

[i in 1..10| i];
[x in 0..3| x-1];
[x in 1..4| 10];

Expected Output (4 lines since each generator is newline terminated.):

1 2 3 4 5 6 7 8 9 10
-1 0 1 2
10 10 10 10

Depending on the text editor a file is viewed in, the final empty line may not be rendered (like the viewer above). To be sure your test cases adhere to the spec, make use of Dragon-Runner which ensures that generated and expected output match to every single byte.
