Golang Append

While working on some code base, I found out a weird quirk of append built-in function in Golang.

There was a string slice defined and after some operations, the function was returning two things, a string and a string slice.
... s := []string{"a", "b", "c", "d"} ... return s[1], append(s[:1], s[1+1:]...) The output is supposed to be "b" and "a", "c", "d" but what I got was "c" and "a", "c", "d". At first I thought I have discovered a bug but after reading the documentation it became clear that it is intentional. Turns out it has to do with implementation of Slice described in this blog. So, append modifies the underlying array and since arguments are evaluated from right to left, append is executed first which modified the underlying array to become "a", "c", "d" and then s[1] returns the 1st element of the modified array "c"…
We had a fun day at work today. Some new people joined and we planned a challenging treasure hunt in WeWork building for them. Then families of workmates joined us for a logo designing competition. We then played dumb charades and ate Pizzas together.
I finally bought the Interpreter Book on Kindle store.

Vanity Imports in Golang

The imports in Golang are the fullpath of the package including the domain name. It is common to host the packages on Github and use it for import as well. However, there are two problems with it.
Long imports: Packages under Github have to have github.com/<username>/<repository-name> at the beginning which is rather long considering some repositories have nested sub-directories. This is true for internal packages in the repository as well, when you want to import a package from a different sub-directory but you still have to use the entire Github prefix. Hassle in switching the hosting The package name is the unique identifier for the package and having the hosting provider name in it means its a hassle to switch provider even for internal packages.
The two aforementioned problems can be solved using vanity imports in Go. What vanity import means is using a custom domain for package imports.
