This brings in a bugfix for analyzing variables inside relative traversal expressions in HCL, and a cosmetic bugfix in cty for GoString of cty.NullVal(cty.DynamicPseudoType). This also updates some other packages, as a result of running "go get -u". |

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.
