在空手道DSL中，如何将替换文本用于其他数据类型，例如int，float，Big等？

Question

I found the below example on github.

• def text = 'hello world bye'

• replace text | token | value | | one | 'cruel' | | two | 'good' |

• match text == 'hello cruel world good bye'

What If the value I want to replace can only accept integers or other data types? For example,

• replace text | token | value| | hours | 90 | | price | 123.45 | | quantity | 999999999999 |

I was not able to put the token inside another file because the json validator does not like the <> without the double quotes. any suggestions?

Replace is meant for text not JSON, read the doc carefully please. First, there is no problem with numbers and replace:

* def text = 'hello <name> how many <hours>'
* replace text
    | token  | value    |
    | name   | 'John'   |
    | hours  | 200      |
* match text == 'hello John how many 200'

Now, if you are trying to fiddle with JSON, just use the set keyword.

* def json = { hello: '', hours: null }
* set json
    | path   | value    |
    | hello  | 'John'   |
    | hours  | 200      |
* match json == { hello: 'John', hours: 200 }

Note that the above would work even if you omit the first line. Also refer to embedded expressions as another way to substitute values in JSON, refer to the doc.
