FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.
In your command-line run the following commands:
brew doctorbrew update
We Gophers, love table-driven-tests, it makes our unittesting structured, and makes it easy to add different test cases with ease.
Let’s create our table driven test, for convenience, I chose to use t.Log as the test function.
Notice that we don't have any assertion in this test, it is not needed to for the demonstration.
func TestTLog(t *testing.T) {
t.Parallel()| #!/bin/bash | |
| lines=$(tput lines) | |
| cols=$(tput cols) | |
| awkscript=' | |
| { | |
| lines=$1 | |
| random_col=$3 | |
| letter=$4 |
The absolute requirement is that these must be binaries that could go into /usr/bin one day. No python, ruby or js stuff. Not that dynamic languages are bad/evil, but I think system utilities should be binaries. I also think it's interesting that people are writing replacements in Go/Rust/Other that rethink some unix legacy. Replacement doesn't mean better in all cases. I just think it's an interesting time but also a good measure of what these compiled languages can handle/tackle/address. Will we see larger and more impressive CLIs? Or will the feature sets be about the same but the quality/stability/safety be better?
It's going to be reductive to explain some of these tools in one line.
