Demonstrate inconsistent behavior for ansible.parsing.yaml.loader.AnsibleLoader
Two equivalent ways to specifiy the same content:
user@host:~/ansible-yaml-loader-issue$ diff roles/*/tasks/main.yml
8,10c8
< block: |
< extra line with leading TAB;
< another line with leading TAB;
---
> block: "\textra line with leading TAB;\n\tanother line with leading TAB;\n"Different behaviour when running with or without libyaml / CParser:
user@host:~/ansible-yaml-loader-issue$ ./loader.py roles/*/tasks/main.yml
<class '__main__.AnsibleCLoader'> roles/easy_to_read/tasks/main.yml
while scanning a block scalar
in "roles/easy_to_read/tasks/main.yml", line 8, column 12
found a tab character where an indentation space is expected
in "roles/easy_to_read/tasks/main.yml", line 9, column 7
