From 48a48b4f6b1c834aaf8b3574efa521a073039613 Mon Sep 17 00:00:00 2001 From: Elliot Winkler Date: Fri, 19 Jun 2020 00:38:50 -0600 Subject: [PATCH] Add a way to elide diffs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When looking at a large diff for which many of the lines do not change, it can be difficult to locate the lines which do. Text-oriented diffs such as those you get from a conventional version control system solve this problem by removing those unchanged lines from the diff entirely. For instance, here is a section of the README with a line removed. Notice that only the part of the file we care about, which is around the line deleted, is displayed in the diff: ``` diff --git a/README.md b/README.md index 56b046c..b38f4ca 100644 --- a/README.md +++ b/README.md @@ -169,7 +169,6 @@ SuperDiff.configure do |config| config.add_extra_differ_class(YourDiffer) config.add_extra_operation_tree_builder_class(YourOperationTreeBuilder) config.add_extra_operation_tree_class(YourOperationTree) - config.add_extra_diff_formatter_class(YourDiffFormatter) end ``` This commit implements a similar feature for data-oriented diffs. It adds two new configuration options to allow you to control the elision logic: * `diff_elision_enabled` — The elision logic is disabled by default so as not to surprise people, so setting this to `true` will turn it on. * `diff_elision_maximum` — This number controls what happens to unchanged lines (i.e. lines that are neither "insert" lines nor "delete" lines) that are in between changed lines. If a section of unchanged lines is beyond this number, the gem will elide (a fancy word for remove) the data structures within that section as much as possible until the limit is reached or it cannot go further. Elided lines are replaced with a `# ...` marker. Here are a few examples: \### Elision enabled If you add this to your test helper: ``` ruby SuperDiff.configure do |config| config.diff_elision_enabled = true end ``` And you have this test: ``` ruby expected = [ "Afghanistan", "Aland Islands", "Albania", "American Samoa", "Andorra", "Angola", "Anguilla", "Antarctica", "Antigua And Barbuda", "Argentina", "Aruba", "Australia" ] actual = [ "Afghanistan", "Aland Islands", "Algeria", "American Samoa", "Andorra", "Angola", "Anguilla", "Antarctica", "Antigua And Barbuda", "Armenia", "Aruba", "Australia" ] expect(actual).to eq(expected) ``` Then you will get a diff that looks like: ``` [ # ... - "Albania", + "Algeria", # ... - "Argentina", + "Armenia", "Aruba", "Australia" ] ``` \### Elision enabled and maximum specified Configuration: ``` ruby SuperDiff.configure do |config| config.diff_elision_enabled = true config.diff_elision_maximum = 5 end ``` Test: ``` expected = [ "Afghanistan", "Aland Islands", "Albania", "American Samoa", "Andorra", "Angola", "Anguilla", "Antarctica", "Antigua And Barbuda", "Argentina", "Aruba", "Australia" ] actual = [ "Afghanistan", "Aland Islands", "Algeria", "American Samoa", "Andorra", "Angola", "Anguilla", "Antarctica", "Antigua And Barbuda", "Armenia", "Aruba", "Australia" ] expect(actual).to eq(expected) ``` Resulting diff: ``` [ "Afghanistan", "Aland Islands", - "Albania", + "Algeria", "American Samoa", "Andorra", # ... "Antarctica", "Antigua And Barbuda", - "Argentina", + "Armenia", "Aruba", "Australia" ] ``` \### Elision enabled and maximum specified, but indentation limits complete elision Configuration: ``` ruby SuperDiff.configure do |config| config.diff_elision_enabled = true end ``` Test: ``` ruby expected = { foo: { bar: [ "one", "two", "three" ], baz: "qux", fizz: "buzz", zing: "bing" } } actual = [ foo: { bar: [ "one", "two", "tree" ], baz: "qux", fizz: "buzz", zing: "bing" } ] expect(actual).to eq(expected) ``` Resulting diff: ``` { foo: { bar: [ # ... - "three" + "tree" ], # ... } } ``` Notice how we cannot fully elide all of the unchanged lines in this case because otherwise the diff would look like this and it wouldn't make sense: ``` # ... - "three" + "tree" # ... ``` --- CHANGELOG.md | 50 +
