如何使用R晶须模板引擎生成带换行的编号列表

Question

我有以下数据：

data <- list( name = "Chris",
             children_names = c("Alex", "John")
            )

使用R的模板引擎https://github.com/edwindj/whisker，当呈现时，我希望得到这个输出：

I am Chris
My children are:
    Child No 1 is Alex
    Child No 2 is John

这是我目前的代码：

library(whisker)
template <- 
'I am {{name}}
My children are:
{{children_names}}
'

data <- list( name = "Chris",
             children_names = c("Alex", "John")
            
            )

text <- whisker.render(template, data)
cat(text)

# which produces:

# I am Chris
# My children are:
# Alex,John

这不是我想要的。正确的方法是什么？

Answer 1

您可能已经知道了，但如果您还没有：

library(whisker)

template <- 
  'I am {{name}} \n
  My children are: \n
  {{#children_names}}
  Child No {{number}} is {{cname}}
  {{/children_names}}'

data <- list( 
  name = "Chris",
  children_names = list(
    list(cname = "Alex", number = 1), list(cname = "John", number = 2)
  )
)

text <- whisker.render(template, data)
cat(text)

# I am Chris 
# 
# My children are: 
#   
# Child No 1 is Alex
# Child No 2 is John
