queen-attack: represent positions as objects #935
Conversation
|
Nice change! Please also bump the canonical data version as appropriate: https://github.com/exercism/problem-specifications#test-data-versioning :) |
|
@stkent Thanks for the reminder, totally forgot about that! Since we're changing the type of one of the data keys I assume this is a major bump, correct? |
|
That would be my interpretation of the guidelines, yes! |
|
Thanks, bumped major number. |

The description uses the terms row and column I think we should stick with those.

Agree with @Insti, we should follow what is in the description (or else change the description).

I'd argue against changing the description. (But it is certainly an option.)

I agree, row/column works great for me. Made the change.

As with #936, I do not think that the proposed changes justify a major bump.
1.0.1 should be bumped enough, since only representation of testdata changed, which each language is free to choose anyway and no one is forced to change anything in the corresponding exercises of their tracks.

It seems as if I had to revoke my request for changes, as per the version numbering documentation, we have to bump MAJOR when we break test generators, and this changes propably will:
I previously always understood the version as a version of the exercise, to understand evolvement of exercises, but it seems as if it were only meant to check for compatibility in testgenerators, nothing more, nothing less. |

I am glad it is getting done.
No opinion on rank/file vs row/column, but I will remark that I often forget which is which and have to remind myself that we talk about the a-file, b-file, etc., so there is an advantage to row/column even if it is not specific to the domain
Squash on merge.
(Don't worry, I'm not merging until we deal with rank/file vs row/column, this approval just means I ultimately would take either)
|
I'm totally fine with row/column, let's use that. Just submitted the patch. Anything else? |

require 'json'
require_relative '../../verify'
json = JSON.parse(File.read(File.join(__dir__, 'canonical-data.json')))
raise "There should be exactly two cases, not #{json['cases'].size}" if json['cases'].size != 2
verify(json['cases'][0]['cases'], property: 'create') { |c|
c['queen']['position'].values_at('row', 'column').all? { |x| (0...8).cover?(x) } ? 0 : -1
}
verify(json['cases'][1]['cases'], property: 'canAttack') { |c|
w, b = %w(white black).map { |color|
c["#{color}_queen"]['position'].values_at('row', 'column')
}
diffs = w.zip(b).map { |wb| wb.reduce(:-).abs }
diffs.include?(0) || diffs.uniq.size == 1
}says it is good.
Squash on merge.

this is very awkward that the description (and thus the keys in the JSON file) use "row" yet the description uses "rank". We'll want to fix that up later (or now??)

I'm willing to change it now.

a little awkward that these are 0/-1 instead of just true/false. Probably worth fixing later on.

Right now it's using 0/1 as false/true and -1 as error. It would probably be better to use the accepted "error" methodology, but that's probably worth its own pull request. Should one of us open an issue?

I agree that a separate PR for this is a good idea.

@petertseng I made the changes in the test case descriptions like you mentioned. |
queen-attack: use rank/file instead of x and y queen-attack: bump major version for queen-attack queen-attack: Use row/column instead of rank/file in test keys queen-attack: use row/column instead of rank/file in json descriptions

Closes #721.
I decided to use objects, since it seems like most people were agreeing it was more explicit. I will also be using objects to encode the position for #722, which is deals with a similar issue.
