Avoid typing out all go files in the main package when "Go run"-ng
问题
当你在main包中有多个.go文件时，在执行go run命令时，需要将它们全部列出。
所以当我有main.go、a.go、b.go这三个文件，它们都属于main包，为了使用其他两个go文件中的函数和结构体，我需要输入go run main.go a.go b.go。然而，go build命令会自动智能地将所有文件链接在一起。
我是否对Go有什么误解，或者这种情况是正常的（在执行go run时列出main包中的所有文件）？
英文:
When you have multiple .go files in a main package, i need to list them all out when doing a go run.
So when i have main.go, a.go, b.go and they all belong to the main package, i need to type go run main.go a.go b.go in order to use functions and structs inside the other 2 go files. The go build command however, is smart enough to link all files together automatically.
Have i misunderstood something about Go, or is this normal (listing out all the files in the main package when doing a go run)?

简短回答是：你需要将它们全部列出来。如果你非常着急，你可以使用shell技巧来实现。通常我会编写一个shell脚本来进行go build，然后运行生成的可执行文件，当它变得太烦人时。
# 这个方法适用于没有_test.go文件的情况
go run *.go
# 如果你真的想要...启用扩展的glob
shopt -s extglob
# 这样你就可以做类似这样的事情（匹配除了*_test.go文件之外的所有.go文件）
go run !(*_test).go

The short answer is: you need to list them all out. You can do this with shell tricks, if you're desperate. I usually just write a shell script to go build and then run the resulting executable, after it gets too annoying.
# this works unless you have _test.go files
go run *.go
# if you really want to... enable extended glob
shopt -s extglob
# so you can do something like this (matches all .go except *_test.go files)
go run !(*_test).go

如果你的源代码位于$GOPATH/src目录下，例如：
$GOPATH/src/somedir/main.go
$GOPATH/src/somedir/a.go
$GOPATH/src/somedir/b.go
执行"go install somedir"命令将会编译并安装somedir二进制文件到$GOPATH/bin目录下，无需逐个列出文件。
"go install"命令会自动找到所有的文件。
我的常用Go工作流程是（在我的bash提示符下）：
$ clear; go install myproj && $GOPATH/bin/myproj
这个命令会清屏，构建并安装"myproj"，然后运行它。
所以，当我修改代码后，只需要按Ctrl-C，上箭头和回车键。
整个循环时间约为1秒（适用于小型项目）。
英文:
If your source is in $GOPATH/src
as in
$GOPATH/src/somedir/main.go
$GOPATH/src/somedir/a.go
$GOPATH/src/somedir/b.go
doing "go install somedir" will compile and install the somedir binary in to $GOPATH/bin
no need to list out the files individually
"go install" finds all the files on it's own.
My common work cycle with go is (from my bash prompt):
$ clear; go install myproj && $GOPATH/bin/myproj
which, clears the screen, builds and installs "myproj" and then runs it
so, after I change code, I just hit Ctrl-C, Up arrow, and enter.
Entire cycle time is ~1 second (for small to start stuff)
