A rebase switches the meaning of "ours" and "theirs": git checkout topic git rebase master # rebase topic branch on top of master branch Whatever HEAD's pointing to is "ours" The first thing a rebase does is resetting the HEAD to master; before cherry-picking...

Check whether a string is empty: if str.isEmpty { // do something if the string is empty } // If the string is empty, replace it with a fallback: let result = str.isEmpty ? "fallback string" : str Check whether two strings are equal (in the sense of Unicode canonical equivale...

Given the following input: aaaaaAlazyZgreeedyAlaaazyZaaaaa We will use two patterns: one greedy: A.*Z, and one lazy: A.*?Z. These patterns yield the following matches: A.*Z yields 1 match: AlazyZgreeedyAlaaazyZ (examples: Regex101, Rubular) A.*?Z yields 2 matches: AlazyZ and AlaaazyZ (exampl...

This layout uses one floated column to create a two-column layout with no defined widths. In this example the left sidebar is "lazy," in that it only takes up as much space as it needs. Another way to say this is that the left sidebar is "shrink-wrapped." The right content column...

Functions can return values by specifying the type after the list of parameters. func findHypotenuse(a: Double, b: Double) -> Double { return sqrt((a * a) + (b * b)) } let c = findHypotenuse(3, b: 5) //c = 5.830951894845301 Functions can also return multiple values using tuples. f...

A data.frame is a special kind of list: it is rectangular. Each element (column) of the list has same length, and where each row has a "row name". Each column has its own class, but the class of one column can be different from the class of another column (unlike a matrix, where all elemen...
