Unicode.Transform.Compiler (Unicode Transform v1.1.0)

Copy Markdown View Source

Compiles parsed transform rules into an executable form.

The compiler takes a list of parsed rule structs and a direction, and produces a CompiledTransform that can be executed by the engine.

Compilation involves:

  • Filtering rules by direction (forward vs inverse).

  • Resolving variable definitions.

  • Grouping conversion rules into passes (split by transform rules).

  • Compiling patterns for efficient matching.

Summary

Functions

compile(rules, direction, resolve_transform \\ fn _, _ -> nil end, context \\ %{})

Compiles a list of parsed rules into an executable form.

compile_builtin(name, direction)

Compiles a built-in transform.

Functions

compile(rules, direction, resolve_transform \\ fn _, _ -> nil end, context \\ %{})

@spec compile([struct()], :forward | :reverse, function(), map()) ::
  Unicode.Transform.Compiler.CompiledTransform.t()

Compiles a list of parsed rules into an executable form.

Arguments

  • rules — list of parsed rule structs.

  • direction — :forward or :reverse.

  • resolve_transform — function to resolve transform names.

Returns

A CompiledTransform struct.

compile_builtin(name, direction)

@spec compile_builtin(String.t(), :forward | :reverse) ::
  Unicode.Transform.Compiler.CompiledTransform.t()

Compiles a built-in transform.

Arguments

  • name — the built-in transform name.

  • direction — :forward or :reverse.

Returns

A CompiledTransform struct with a single builtin pass.
