StringTemplate

Quickly and easily apply a template to a target string.

This library allows you to create light-weight templates and then arbitrarily apply them to string instances. You can also pass options that will let you customize the strictness with which a template is applied.

Usage

// Create a template:
let nanpPhoneNumber = String.Template(
  placeholderToken: "X",
  template: "(XXX) XXX-XXXX"
)

// And apply it:
let formatted = try? "5125550001".applying(template: nanpPhoneNumber)
print(formatted) // Optional("(512) 555-0001")

// Allow for partial application:
let partial = try? "512555".applying(template: nanpPhoneNumber, options: [.allowPartial])
print(partial) // Optional("(512) 555-")

// Allow for overflow application:
let overflow = try? "5125550001111111111".applying(template: nanpPhoneNumber, options: [.allowOverflow])
print(overflow) // Optional("(512) 555-0001")

// Mutate the string directly:
var str = "5125550001"
try? str.apply(template: nanpPhoneNumber)
print(str) // "(512) 555-0001"

See the tests for more examples.
