How to write an ansible yaml file by clojure? - clojure

Question

I have this simple ansible yaml file,it works fine:
---
- hosts: 172.16.10.104
- tasks:
- name: ping
ping: ''
I use a clojure https://github.com/owainlewis/yaml to use clojure to generate this yaml file:
(defn -main
[& args]
(def data [{:hosts "172.16.10.104"} {:tasks ""} {:name "ping",:ping ""} ])
(def a (yaml/generate-string data :dumper-options {:flow-style :block}))
(println a)
)
this code can generate the yaml file:
- hosts: 172.16.10.104
- tasks: ''
- name: ping
ping: ''
it can't work,the "- name" have to beyond two character of "-tasks"
if I define data like this:
(def data [{:hosts "172.16.10.104"} {:tasks ""} [{:name "ping",:ping ""}]])
it generate this:
- hosts: 172.16.10.104
- tasks: ''
- - name: ping
ping: ''
it can't work too
I don't know how to write the clojure file to generate yaml file like this,Thanks!

Answer 1

Try nesting the :name map:
(let [data [{:hosts "172.16.10.104"}
{:tasks [{:name "ping"}
{:ping ""}]}]]
(println (yaml/generate-string data)))
with result:
- {hosts: 172.16.10.104}
- tasks:
- {name: ping}
- {ping: ''}

Also, you might want to consider using github.com/clj-commons/clj-yaml. It’s the lib circle-ci uses for their yaml stuff
