Go 没有安装 gotype 命令？

Question

我从异地获得了 Go 1.4 / Win32。我看到了 foder "c:\go\bin"。里面没有 gotype 命令。我需要gotype -- gotype在哪里，如何安装？

Answer 1

2015 年 4 月更新：Go 1.5 应该引入“go doc”：参见

review 9227: cmd/go,cmd/doc: 添加“go doc”
review 9226：将 doc.go 重命名为 alldocs.go 以准备“go doc”

Add the new go doc command to the go command, installed in the tool directory.

usage:

go doc [-u] [package|[package.]symbol[.method]]

原始答案（2015 年 1 月）

你需要：

go get -u golang.org/x/tools/cmd/gotype

这将安装来自 golang.org/x/tools/cmd/gotype 的额外工具：

The gotype command does syntactic and semantic analysis of Go files and packages like the front-end of a Go compiler.
Errors are reported if the analysis fails; otherwise gotype is quiet (unless -v is set).

注意：这不是您可能考虑安装的唯一额外工具，如 this article:

中所示

go get -u golang.org/x/tools/cmd/godoc
go get -u golang.org/x/tools/cmd/vet
go get -u golang.org/x/tools/cmd/goimports
go get -u golang.org/x/tools/cmd/gorename
go get -u golang.org/x/tools/cmd/oracle
go get -u golang.org/x/tools/cmd/gotype
go get -u github.com/golang/lint/golint

注意：Go 1.5 将使该操作更快。
见 commit dc2d64b by Brad Fitzpatrick (bradfitz):

cmd/go: cache results of HTTP requests done during meta tag discovery

Previously, running

$ go get -u -v golang.org/x/tools/cmd/godoc

would results in dozens of HTTP requests for:

https://golang.org/x/tools?go-get=1

once per package under x/tools.

Now it caches the results.
We still end up doing one HTTP request for all the packages under x/tools, but this reduces the total number of HTTP requests in ~half.
