dlv 사용법은 간단하다.
package main
import (
"fmt"
"runtime"
)
func main() {
runtime.Breakpoint() // 이런식으로 등록을 해주고..
a := 1 // 이후에 dlv 실행후 print a 이런식으로 찍어볼 수가있음
fmt.Println("Hello world!")
fmt.Println(a)
}dlv debug 또는 dlv test 를 해서.. gdb 방식으로 debug 를 하면된다.
continue, print, restart 등등 유용한 명령어가 많이 있다.

> }vim-go의 built-in debugger을 사용하는방법..
vim-go 설치이후 빔내에서 F9를 눌러버리면, > 이런식으로 브레이크 포인터가 생긴다.
이후 사용방법은 vim-go 레퍼런스에 자세하게 나와있다. https://github.com/fatih/vim-go/blob/master/doc/vim-go.txt
F9 Breakpoint, F8 Continue, F10 Next, F11 Step
Toggle breakpoint for the [linenr]. [linenr] defaults to the current line
if it is omitted. A line with a breakpoint will have the
{godebugbreakpoint} |:sign| placed on it. The line the program is
currently halted on will have the {godebugcurline} sign.
*hl-GoDebugCurrent* *hl-GoDebugBreakpoint*
A line with a breakpoint will be highlighted with the {GoDebugBreakpoint}
group; the line the program is currently halted on will be highlighted
with {GoDebugCurrent}.
Mapped to <F9> by default.
*:GoDebugContinue*
*(go-debug-continue)*
:GoDebugContinue
Continue execution until breakpoint or program termination. It will start
the program if it hasn't been started yet.
Mapped to <F5> by default.
*:GoDebugNext*
*(go-debug-next)*
