Patch Changes

• #4113 1c08a0b Thanks @thewilkybarkid! - Schema: Support template literals in Schema.Config.

  Example

  import { Schema } from "effect"
  
  // const config: Config<`a${string}`>
  const config = Schema.Config(
    "A",
    Schema.TemplateLiteral(Schema.Literal("a"), Schema.String)
  )

• #4174 1ce703b Thanks @gcanti! - Schema: Add support for TemplateLiteral parameters in TemplateLiteral, closes #4166.

  This update also adds support for TemplateLiteral and TemplateLiteralParser parameters in TemplateLiteralParser.

  Before

  import { Schema } from "effect"
  
  const schema = Schema.TemplateLiteralParser(
    "<",
    Schema.TemplateLiteralParser("h", Schema.Literal(1, 2)),
    ">"
  )
  /*
  throws:
  Error: Unsupported template literal span
  schema (TemplateLiteral): `h${"1" | "2"}`
  */

  After

  import { Schema } from "effect"
  
  // Schema<readonly ["<", readonly ["h", 2 | 1], ">"], "<h2>" | "<h1>", never>
  const schema = Schema.TemplateLiteralParser(
    "<",
    Schema.TemplateLiteralParser("h", Schema.Literal(1, 2)),
    ">"
  )
  
  console.log(Schema.decodeUnknownSync(schema)("<h1>"))
  // Output: [ '<', [ 'h', 1 ], '>' ]

• #4174 1ce703b Thanks @gcanti! - Schema: Fix bug in TemplateLiteralParser where unions of numeric literals were not coerced correctly.

  Before

  import { Schema } from "effect"
  
  const schema = Schema.TemplateLiteralParser("a", Schema.Literal(1, 2))
  
  console.log(Schema.decodeUnknownSync(schema)("a1"))
  /*
  throws:
  ParseError: (`a${"1" | "2"}` <-> readonly ["a", 1 | 2])
  └─ Type side transformation failure
     └─ readonly ["a", 1 | 2]
        └─ [1]
           └─ 1 | 2
              ├─ Expected 1, actual "1"
              └─ Expected 2, actual "1"
  */

  After

  import { Schema } from "effect"
  
  const schema = Schema.TemplateLiteralParser("a", Schema.Literal(1, 2))
  
  console.log(Schema.decodeUnknownSync(schema)("a1"))
  // Output: [ 'a', 1 ]
  
  console.log(Schema.decodeUnknownSync(schema)("a2"))
  // Output: [ 'a', 2 ]
  
  console.log(Schema.decodeUnknownSync(schema)("a3"))
  /*
  throws:
  ParseError: (`a${"1" | "2"}` <-> readonly ["a", 1 | 2])
  └─ Encoded side transformation failure
     └─ Expected `a${"1" | "2"}`, actual "a3"
