Adding '-verbose' will print out the allocation information for the deployment. This also changes the job run command so that it now blocks until deployment is complete and adds timestamps to the output so that it's more in line with the output of node drain. This uses glint to print in place in running in a tty. Because glint doesn't yet support cmd/powershell, Windows workflows use a different library to print in place, which results in slightly different formatting: 1) different margins, and 2) no spinner indicating deployment in progress.
go-wordwrap
go-wordwrap (Golang package: wordwrap) is a package for Go that
automatically wraps words into multiple lines. The primary use case for this
is in formatting CLI output, but of course word wrapping is a generally useful
thing to do.
Installation and Usage
Install using go get github.com/mitchellh/go-wordwrap.
Full documentation is available at http://godoc.org/github.com/mitchellh/go-wordwrap
Below is an example of its usage ignoring errors:
wrapped := wordwrap.WrapString("foo bar baz", 3)
fmt.Println(wrapped)
Would output:
foo
bar
baz
Word Wrap Algorithm
This library doesn't use any clever algorithm for word wrapping. The wrapping is actually very naive: whenever there is whitespace or an explicit linebreak. The goal of this library is for word wrapping CLI output, so the input is typically pretty well controlled human language. Because of this, the naive approach typically works just fine.
In the future, we'd like to make the algorithm more advanced. We would do so without breaking the API.
