@adrienverge Could you be a little bit more verbose about it?

[Andrew Imeson]

@dosas this is an issue report with a lot of duplicates (e.g. #430). It's not a problem, it's intended default behavior.

Your options are:

1. Quote the key

   ---
   name: Run tests
   
   "on": [push, pull_request]

2. Disable the rule with a line comment

   ---
   name: Run tests
   
   on: [push, pull_request]  # yamllint disable-line rule:truthy

3. Disable key checking in the yamllint configuration (e.g. .yamllint.yaml)

   ---
   extends: default
   rules:
     truthy:
       check-keys: false

Thanks @andrewimeson 🙏

Since #650 and yamllint 1.34.0 there is yet another solution: declare the YAML version explicitly:

%YAML 1.2
---
name: Run tests

on: [push, pull_request]
