caml's Issues

Error when parsing values in lists

Constructs like the following:

arr: [
  'one',
  'http://two'
]

Causes parsing errors: throw new Error('Key contains incomplete quoted section: "' + line + '"');

bug when parsing object with `.` in key and array as value

# cat test.yml 
foo:
  'baz.qux':
    - lorem
    - ipsum

// caml -d . -f test
{ foo: { '\'baz': { 'qux\'': [ 'lorem', 'ipsum' ] } } }

Inline comments cause loss of properties

Oriniginally submitted by @asgoth - the sanitise step is too eager. Using comments after a property causes the property to disappear, e.g.

path:
  to:
    some: "value" # some explanation what this does
    other: "value"

Results in

{
  path: {
    to: {
      other: "value"
    }
  }
}

Property some is gone.

Workaround: Keep your comments on a dedicated line

Improvement: provide a syntax to merge arrays

Sometimes it is needed to merge arrays, e.g. when you want to expand a default list of types.

Maybe the following syntax could be used:

files:
  +: *baseFiles
  - "path/to/file1"
  - "path/to/file2"

Help statement

Error output is not really helpful:

$ caml
Flag '-i' or '--input' is mandatory. e.g. --input a b c, cascades a.yml, b.yml and c.yml.

The -i flag doesn't exist anymore, should be -f or --files

regex for sanitising is invalid

Regex /[",'].*\..*[",']:/ matches stuff like the following yaml file incorrectly:

'"this is": a': test

In yaml:

> require('js-yaml').safeLoad(require('fs').readFileSync('test.yml'))
{ '"this.is": a': 'test' }

In caml:

$ caml -f test
