Kata

anyone could check & approve it? https://www.codewars.com/kumite/5ef69878d4a55a002491ceca?sel=5ef69878d4a55a002491ceca

Thanks for the encouraging words :D I have thought about it before, perhaps adding a "pattern syntax" which would allow RoboScript "programmers" to define and reuse certain patterns of movement, much like a watered-down version of functions/methods in other programming languages; however, I currently do not have the time to do so and I am not sure whether I can ensure that such a Kata would not be buggy :p After all, despite the rank shown on my profile, I usually struggle quite badly with Kata that are 5kyu and above.

That being said, the fact that you've mentioned it has made me reconsider whether I should continue this Series in the near future (after my A-Level exams, that is). Thanks for your precious feedback!

@hufftheweevil,

I'm glad to announce that the 4th Kata in this series is now available in PHP :D The link to RoboScript #4 can be found at the bottom of the "Kata in this Series" section. If PHP is not your language, don't worry - I will publish a JavaScript translation soon. Stay tuned :)

Cheers, @donaldsebleung

And ... it is now available in JavaScript!

Wow that was fast! I'll check it out later today. Thanks!

This makes a zoomed out (smaller font) and scrollable message on failure. I also changed the color so it's easier to find the "Expected" and "Actual" lines.

//Test.assertEquals(actual, expected);
var expected = solution(code);
var actual = execute(code);
if (actual === expected) {
  Test.expect(true);
} else {
  console.log('Expected:\n\n<pre style="overflow-x: scroll; font-size:4px; color: white; background-color: black;">' + expected + '</pre>\n\nActual:\n\n<pre style="overflow-x: scroll; font-size:4px; color: white; background-color: black;">' + actual + '</pre>');
  Test.expect(false, 'failed a test for a randomly generated RS2 program');
}

The code above only writes the generated program on failure so it should be possible to increase the number of tests by stopping at first failure.

Nice! That might just work. :]

@donaldsebleung, remove these 3 lines.

// Test.assertEquals(actual, expected);
var expected = solution(code);
var actual = execute(code);

I think // Test.assertEquals(actual, expected); from my code confused you, sorry.

Thanks, just realised my random tests were computing the same thing twice, removed :)

One more fix, replace console.log(...) with:

console.log('Expected:\n\n<pre style="overflow-x: scroll; font-size: 8px; line-height: 1; color: white; background-color: black;">' + expected + '</pre>\n\nActual:\n\n<pre style="overflow-x: scroll; font-size: 8px; line-height: 1; color: white; background-color: black;">' + actual + '</pre>');

Added line-height: 1; and increased font-size a bit, so it appears more square. I think it looks much better :)

Thank you for your suggestion, I will add it in my spare time :)

Actually, yes, we need more. :]

You're testing (..)0 but not R0.

I almost managed to squeeze by with another bug (caught in further testing this time :).

Just added a whole bunch of F0s, L0s and R0s in my zero postfix edge cases; feel free to inform me of any more holes in the test fixtures :)

The description says exactly what it means when it says your solution should work for all non-negative integers.

I was just making sure if it's intentional (not an error of random number generator) and wanted to clarify. Sorry if it bothered you. I had already solved, upvoted and ranked before above post. Thanks for this series and answering my question :)

You're welcome :) I apologise if my last sentence sounded a bit angry - I did not mean it at all :)

No problem :] Sometimes it's just hard to tell the tone :(

@donaldsebleung, can you view my solution? I have this kata marked solved and "Solutions" tab on my profile lists it, but I only see your and @smile67's solutions when I visit this kata's "Solutions".

I had this problem before on another kata. After a few hours or a day my solution was suddenly visible...

@Ablinne, thanks for the info. I just submitted again removing a blank line and that's visible now :|

edit: Now "Solutions" tab on my profile has one from "2 hours ago" and "3 minutes ago". Only difference is a single blank line between function declarations. Maybe I should've waited more patiently :(
