Overview

Messaging strategy that refers to an internal Hash of templates.

Internally, the templates Hash is flattened - a nested Hash of { foo: { bar: { baz: ‘template’ } } } is stored as a flat Hash with { ‘foo.bar.baz’ => ‘template’ }. This makes lookup of scoped keys more efficient but prevents retrieving non-leaf nodes (such as “foo” or “foo.bar” in the above Hash). If you need to retrieve Hash values, initialize the strategy with flatten_templates: false.

Constructor

#initialize(templates, flatten_templates: true) => HashStrategy

Parameters

• templates (Hash) — the templates used to generate messages.
• flatten_templates (true, false) — if true, the templates are flattened internally. Defaults to true.

Returns

• (HashStrategy) — a new instance of HashStrategy

Instance Methods

#call(key, parameters: {}, scope: nil, **options) => String

Inherited From

SleepingKingStudios::Tools::Messages::Strategy

Generates a formatted string for the given key, parameters, and options.

If the strategy does not define a message for the key, you can provide a default value.

• If the default value is a Proc, it will be called with the fully scoped key, as a positional argument as well as any additional keywords passed to #call. The value returned by the Proc will be returned by #call.
• If the default value is any other Object (including nil), the default value will be returned by #call.
• If a default value is not provided, a missing message warning will be generated and returned.

Parameters

• key (String, Symbol) — the key used to resolve the message.
• default (Object) — the default value to return if the strategy does not define a message for the key.
• parameters (Hash) — the parameters used to generate the message, such as values for a template string.
• scope (String) — the namespace for the key. Combined with the given key to generate the scoped key value.
• options (Hash) — additional options for resolving or generating the message.

Returns

• (String) — the generated template string, or a generic error string if a message is not defined for the given key and parameters.

#fetch(key, default = nil, scope: nil, **options) => Object
#fetch(key, scope: nil, **options, &default) => Object

Inherited From

SleepingKingStudios::Tools::Messages::Strategy

Overloads

#fetch(key, default = nil, scope: nil, **options) => Object

Retrieves the messages template with the given scope and options.

If there is no template matching the given key, scope, and options, returns the default value or raises a KeyError if no default value is provided.

Parameters

• key (String, Symbol) — the key used to resolve the message.
• default (Object) — the default value to return if the strategy does not define a message for the key.
• scope (String) — the namespace for the key. Combined with the given key to generate the scoped key value.
• options (Hash) — additional options for resolving or generating the message.

Returns

• (Object) — the stored template for the requested key, or the provided default value.

#fetch(key, scope: nil, **options, &default) => Object

If there is no template matching the given key, scope, and options, the block is called with the scoped key and the value returned by the block is returned by #fetch.

Parameters

• key (String, Symbol) — the key used to resolve the message.
• scope (String) — the namespace for the key. Combined with the given key to generate the scoped key value.
• options (Hash) — additional options for resolving or generating the message.

Yield Parameters

• scoped_key (String) — the fully scoped key for the requested template, combining the given key and the given scope, if any.
• options (Hash) — additional options for resolving the message.

Yield Returns

• (Object) — the default value for the given scoped key.

Returns

• (Object) — the stored template for the requested key, or the value returned by the provided default block.

Raises

• (KeyError)

#get(key, scope: nil, **options) => Object

Inherited From

SleepingKingStudios::Tools::Messages::Strategy

Retrieves the messages template with the given scope and options.

Parameters

• key (String, Symbol) — the key used to resolve the message.
• scope (String) — the namespace for the key. Combined with the given key to generate the scoped key value.
• options (Hash) — additional options for resolving or generating the message.

Returns

• (Object) — the stored template for the requested key, or nil if there is no matching template.
