## yamlpp-schema-convert

Experimental script to convert types like booleans and numbers in a given

YAML file from YAML 1.1 to 1.2. Keeps all whitespace and comments.

To get an impression on how many things are different in the two YAML versions,

have a look at the comparison of the [YAML 1.2 Core Schema and YAML 1.1

Types](https://perlpunk.github.io/yaml-test-schema/data.html).

Not only booleans are different, but also tiny details in number formats.

See example files [in.yaml](/data/in.yaml) and [out.yaml](/data/out.yaml).

Example usage:

    % echo 'yes' | perl bin/yamlpp-schema-convert -

    true

    % echo '0o7' | perl bin/yamlpp-schema-convert -

    '0o7'

    % perl bin/yamlpp-schema-convert data/in.yaml > data/out.yaml

    % vimdiff data/in.yaml data/out.yaml

To highlight the files and see things like trailing spaces, you can use:

    % yamlpp-highlight data/in.yaml

    % yamlpp-highlight data/out.yaml

### Dependencies

Perl modules:

* YAML::PP 0.22 [Repology](https://repology.org/project/perl:yaml-pp/versions)

* Getopt::Long::Descriptive [Repology](https://repology.org/project/perl:getopt-long-descriptive/versions)

### Limitations

Because this uses the lowlevel token API, it can't detect certain things.

Correct:

    - YES

    # will be converted to

    - true

Correct:

    - !!str YES

    # not converted

    - !!str YES

Not correct:

    - !!str

       YES

    # will be converted to

    - !!str

       true

Also it doesn't convert quoted strings:

    - !!bool 'yes'

    # not converted

    - !!bool 'yes'
