Replace embedded resource text files with inline data for Intl CLDR data by lahma · Pull Request #2343 · sebastienros/jint (original) (raw)
Convert 6 of 7 embedded .txt resource files in Jint/Native/Intl/Data/ to inline static readonly dictionary initializers in companion .Data.cs partial class files. This eliminates runtime text parsing, StreamReader allocations, and reflection-based GetManifestResourceStream calls for these data files.
LikelySubtags.txt (133 KB) is kept as an embedded resource since inline dictionary entries would add ~217 KB to the DLL due to UTF-16 string encoding. Its loader is updated from the non-thread-safe ??= pattern to Lazy.
ComplexLanguageMapping and VariantMapping structs converted to readonly record structs with primary constructors.
