A block is shorthand for defining a template:
|
||
|
|
|
||
|
|
```go-html-template
|
||
|
|
{{ define "name" }} T1 {{ end }}
|
||
|
|
```
|
||
|
|
|
||
|
|
and then executing it in place:
|
||
|
|
|
||
|
|
```go-html-template
|
||
|
|
{{ template "name" pipeline }}
|
||
|
|
```
|
||
|
|
The typical use is to define a set of root templates that are then customized by redefining the block templates within.
