Scripts for testing programming problem solutions.

Will compile and run the source (C++17, Java or Python3). The memory-limit is in MBs (default: 256).

If input.txt exists, will do:

rr solution <input.txt >stdout.txt

and then if output.txt exists, will do:

diff stdout.txt output.txt

Otherwise, if tests.txt exists, will extract each test case into input.txt and output.txt, and will do:

tt solution

The tests.txt should look like:

input:
...
output:
...

input:
...
output:
...

Tip: the following bookmarklet scrapes sample tests from codeforces.com problem statement and downloads them in a tests.txt file:

javascript:
var inputs = document.querySelectorAll('.input pre');
var outputs = document.querySelectorAll('.output pre');

var data = '';
for (var i = 0; i < inputs.length; i++) {
    data += 'input:\n' + inputs[i].innerText.replace(/\n*$/, '\n');
    data += 'output:\n' + outputs[i].innerText.replace(/\n*$/, '\n\n');
}

var a = document.createElement('a');
a.setAttribute('href', 'data:text/plain,' + encodeURIComponent(data));
a.setAttribute('download', 'tests.txt');
document.body.appendChild(a);
a.click();

Will do:

while true; do
  rr generator >input.txt
  tt solution
done

Will do:

while true; do
  rr generator >input.txt
  rr solver <input.txt >output.txt
  tt solution
done

Will compile the source (C++17) and start gdb.
