Padre::Plugin::YAML

YAML plug-in that provides background syntax checking

To-Do

• tidy up code
• syntax panel dose not show a green square when clean
  • food for thought, was fun, still looking

Limitations

By using YAML::XS

• directives are supported only for the %YAML 1.1 or none

%YAML 1.1
# --- document separator
---
plack_middlewares:
  -
    - Expires
    - Deflater
    - StackTrace
    - Debug
    - panels
    -
      - Parameters
      - Dancer::Version
      - Dancer::Settings
      - Memory
      - PerlConfig
      - DBITrace 
      - ModuleVersions
...
# comments like so
---
rootproperty: blah
section:
  one: two
  three: four
  Foo: Bar
  empty: ~
# ... indicate the end of a document
...

Another example

%YAML 1.1
---
 - - item 1
   - item 2
 - key 1: value 1
   key 2: value 2
 - ? complex key
   : complex value
...
