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 the 415 Tester which ensures that generated and expected output match to every single byte.
