Extracts just the message keys for stale detection.

Returns a MapSet of tuples: {msgid, domain, context}

Arguments

• base_path - Base directory to search for PO files
• allowed_locales - Optional list of locale codes to filter by

Examples

iex> POFileParser.extract_message_keys("/path/to/priv/gettext")
#MapSet<[
  {"Welcome", "default", "default"},
  {"Hello %{name}", "default", "greetings"},
  {"Error occurred", "errors", "default"}
]>

Extracts message keys for a single locale only.

Convenience wrapper around extract_message_keys/2 for per-locale detection.

Arguments

• base_path - Base directory to search for PO files
• locale_code - Single locale code (e.g., "en", "it")

Examples

iex> POFileParser.extract_message_keys_for_locale("/path/to/priv/gettext", "en")
#MapSet<[
  {"Welcome", "default", "default"},
  {"Hello %{name}", "default", "greetings"}
]>

Finds all PO files in the given base directory.

Arguments

• base_path - Base directory to search for PO files (e.g., "/path/to/priv/gettext" or "test/fixtures")
• allowed_locales - Optional list of locale codes to filter by (e.g., ["en", "pl"])

Returns

List of maps with keys:

• :path - Full path to the PO file
• :locale - Locale code (e.g., "en", "pl")
• :domain - Domain name (e.g., "default", "errors")

Examples

iex> POFileParser.find_po_files("/path/to/priv/gettext")
[
  %{path: "/path/to/priv/gettext/en/LC_MESSAGES/default.po", locale: "en", domain: "default"},
  %{path: "/path/to/priv/gettext/pl/LC_MESSAGES/default.po", locale: "pl", domain: "default"}
]

iex> POFileParser.find_po_files("/path/to/priv/gettext", ["en"])
[
  %{path: "/path/to/priv/gettext/en/LC_MESSAGES/default.po", locale: "en", domain: "default"}
]

Parses all PO files and returns messages with metadata.

Arguments

• base_path - Base directory to search for PO files

Returns

List of maps with keys:

• :path - Full path to the PO file
• :locale - Locale code
• :domain - Domain name
• :messages - List of Expo.Message structs

Examples

iex> POFileParser.parse_all_po_files("/path/to/priv/gettext")
[
  %{
    path: "/path/to/en/default.po",
    locale: "en",
    domain: "default",
    messages: [%Expo.Message.Singular{...}, ...]
