excute home page code, the output space is 4
andyblog opened this issue · comments
When I use the sample code on the home page to execute, the output space is 4, but the output space on the home page is 2. What is the reason for this? Is there a place to configure the number of output spaces?
[root@VPS-BJ ~/test]#go run main.go
--- t:
{Easy! {2 [3 4]}}
--- t dump:
a: Easy!
b:
c: 2
d: [3, 4]
--- m:
map[a:Easy! b:map[c:2 d:[3 4]]]
--- m dump:
a: Easy!
b:
c: 2
d:
- 3
- 4
[root@VPS-BJ ~/test]#ls
go.mod go.sum main.go
[root@VPS-BJ ~/test]#cat go.mod
module test
go 1.19
require gopkg.in/yaml.v3 v3.0.1
var b bytes.Buffer
encoder := yaml.NewEncoder(&b)
encoder.SetIndent(2)
err = encoder.Encode(&m)
if err != nil {
log.Fatalf("error: %v", err)
}
fmt.Printf("--- m dump:\n%s\n\n", b.String())
So SetIndent
can be used to set the indentation. But, regardless you would get this:
--- m dump:
a: Easy!
b:
c: 2
d:
- 3
- 4
and not this as it says in the README.md
--- m dump:
a: Easy!
b:
c: 2
d:
- 3
- 4
