GoLang debugging tool Delve
1. Get it first:
go get -u /derekparker/delve/cmd/dlv
2. Write test code:
func main(){
("/test",func(writer ,req *){
//TODO
})
(("127.0.0.1:8080",nil))
}
start up:
dlv debug
4. Breakpoint:
4.1): Break points for the method:
b main.function name
4.2): Run to the breakpoint:
c
4.3: Break points for a certain line:
You need to get the file location and break the point:
b /Users/joker/go/src/…/:14 break points for 14 lines
As for how to perform operations consistent with the ide: through n,s
- n: F6 equivalent to Java-Eclipse
- s: F5 equivalent to Java-Eclipse
How to view variables:p
p testName will output the value of testName
args: will output all method parameter information
locals: will output all local variables
The command line compilation of emmmmmmmmm golang feels very inconvenient, so I'd better find a way to get it on the idea.
Use go to play Debug, Info, Error level log
Directly upload the code:
package mylog
import (
"log"
"os"
)
var (
Debug *
Info *
Error *
)
func init() {
("init ...")
Debug = (, "[DEBUG] ", ||)
Info = (, "[INFO] ", ||)
Error = (, "[ERROR] ", ||)
}
package main
import "mylog"
func main(){
("good");
("good");
("good");
}
that's all.
