only decode the first block of yaml

[aloisio31]

yaml:

---
hooks:
  AfterInstall:
    - location: /Users/derekmorgan/src/deploy-plugin/afterinstall.sh
      timeout: 2
    - location: /Users/derekmorgan/src/deploy-plugin/afterinstall.sh
      timeout: 2
files:
  - source: ./my-file.txt
    destination: /temp

lua:

tprint(require('yaml').eval(s), 1)
  hooks:
    AfterInstall:
      1:
        location: /Users/derekmorgan/src/deploy-plugin/afterinstall.sh
        timeout: 2
      2:
        location: /Users/derekmorgan/src/deploy-plugin/afterinstall.sh
        timeout: 2

Sounds like it should be parsed, other implementations do:

irb(main):035:0> str="---\nhooks:\n  AfterInstall:\n    - location: /Users/derekmorgan/src/deploy-plugin/afterinstall.sh\n      timeout: 2\n    - location: /Users/derekmorgan/src/deploy-plugin/afterinstall.sh\
n      timeout: 2\nfiles:\n  - source: ./my-file.txt\n    destination: /temp\n"
=> "---\nhooks:\n  AfterInstall:\n    - location: /Users/derekmorgan/src/deploy-plugin/afterinstall.sh\n      timeout: 2\n    - location: /Users/derekmorgan/src/deploy-plugin/afterinstall.sh\n      timeou...
irb(main):036:0> puts str
