📘 Usage: Locres

from pylocres import LocresFile, Namespace, Entry, LocresVersion, entry_hash

# Create Locres file instance
locres = LocresFile()

# Read a .locres file
locres.read("path/to/file.locres")

# Iterate over all namespaces
for namespace in locres:
    print("Namespace:", namespace.name or "<default>")

    # Iterate over all entries in the namespace
    for entry in namespace:
        print("Key:", entry.key) # cf433749-2e... (uuid4 or custom key)
        print("Translation:", entry.translation) # Hello world!
        print("Source Hash:", entry.hash) # 828975897

        # Set a new translation
        entry.translation = "Привіт світ!"

        # Optionally, recalculate source hash
        entry.hash = entry_hash("Hello world!")

# Create a new entry and add it to a namespace
new_entry = Entry("my_key", "My translation", entry_hash("My source"))
namespace.add(new_entry)

# Add a new namespace
new_namespace = Namespace("UI")
locres.add(new_namespace)

# Set file format version (default: CityHash)
locres.version = LocresVersion.CityHash

# Save the modified locres file
locres.write("path/to/output.locres")

# Done

print("Native culture:", locmeta.native_culture) # en
print("Native locres path:", locmeta.native_locres) # en/Game.locres
print("Compiled cultures:", locmeta.compiled_cultures) # ["en", "de", "fr", ...]
