class Bakelite::Transform::Cache

Overview

Content-addressable cache manager for compile-time asset transformations. Caches the results of expensive external tool executions in .bakelite/cache/ keyed by SHA256(file_content + command_string), eliminating repeated process invocations.

Defined in:

bakelite/transform/cache.cr

Constructors

.new(cache_dir : Path | String = ".bakelite/cache")

Instance Method Summary

#cache_dir : Path
#cache_file_path(key : String) : Path
Full path to the cache entry file.
#clear : Nil
Clears all entries in the cache directory.
#compute_key(input_data : Bytes | String, command : String) : String
Computes a deterministic cache key from input bytes and transform command string.
#get?(key : String) : Bytes | Nil
Retrieves cached output bytes, returning nil on cache miss.
#has_key?(key : String) : Bool
Checks if a transformed result exists in cache.
#put(key : String, data : Bytes | String) : Nil
Stores transformed output bytes into cache.
