Types
@type block() :: :msgid | {:msgstr, non_neg_integer()} | :msgctxt | :msgid_plural
The "component" of a message.
@opaque key()
The key that identifies this message.
@opaque meta()
Metadata for this struct.
@type t() :: %Expo.Message.Plural{ __meta__: meta(), comments: [String.t()], extracted_comments: [String.t()], flags: [[String.t()]], msgctxt: Expo.Message.msgctxt() | nil, msgid: Expo.Message.msgid(), msgid_plural: [Expo.Message.msgid()], msgstr: %{required(non_neg_integer()) => Expo.Message.msgstr()}, obsolete: boolean(), previous_messages: [Expo.Message.t()], references: [ [file :: String.t() | {file :: String.t(), line :: pos_integer()}] ] }
The type for this struct.
See %__MODULE__{}
for documentation on the fields of this struct.
Functions
The struct for a plural message.
All fields in this struct are public except for :__meta__
. The :flags
and :references
fields are defined as lists of lists in order to represent lines in the original file. For
example, this message:
#, flag1, flag2
#, flag3
#: a.ex:1
#: b.ex:2 c.ex:3
msgid "Hello"
msgstr ""
would have:
flags: [["flag1", "flag2"], ["flag3"]]
references: [["a.ex:1"], ["b.ex:2", "c.ex:3"]]
You can use Expo.Message.has_flag?/2
to make it easier to check whether a message
has a given flag.
Returns the key of the message.
The key takes the msgctxt into consideration by returning a tuple {msgctxt, msgid}
.
Both msgctxt
and msgid
are normalized to binaries (instead of keeping line information)
for easier comparison.
Examples
iex> Plural.key(%Plural{msgid: ["cat"], msgid_plural: ["cats"]})
{"", "cat"}
Merges two plural messages.
Examples
iex> msg1 = %Expo.Message.Plural{msgid: ["test"], msgid_plural: ["one"], flags: [["one"]], msgstr: %{0 => "une"}}
...> msg2 = %Expo.Message.Plural{msgid: ["test"], msgid_plural: ["two"], flags: [["two"]], msgstr: %{2 => "deux"}}
...> Expo.Message.Plural.merge(msg1, msg2)
%Expo.Message.Plural{msgid: ["test"], msgid_plural: ["two"], flags: [["two", "one"]], msgstr: %{0 => "une", 2 => "deux"}}
Re-balances all strings in the message.
This function does these things:
- Put one string per newline of
msgid
/msgid_plural
/msgstr
- Put all flags onto one line
- Put all references onto a separate line
Examples
iex> Plural.rebalance(%Plural{
...> msgid: ["", "hello", "\n", "", "world", ""],
...> msgid_plural: ["", "hello", "\n", "", "world", ""],
...> msgstr: %{0 => ["", "hello", "\n", "", "world", ""]},
...> flags: [["one", "two"], ["three"]],
...> references: [[{"one", 1}, {"two", 2}], ["three"]]
...> })
%Plural{
msgid: ["hello\n", "world"],
msgid_plural: ["hello\n", "world"],
msgstr: %{0 => ["hello\n", "world"]},
flags: [["one", "two", "three"]],
references: [[{"one", 1}], [{"two", 2}], ["three"]]
}
@spec source_line_number(t(), block(), default) :: non_neg_integer() | default when default: term()
Get the source line number of the message.
Examples
iex> %Expo.Messages{messages: [message]} = Expo.PO.parse_string!("""
...> msgid "foo"
...> msgid_plural "foos"
...> msgstr[0] "bar"
...> """)
iex> Plural.source_line_number(message, :msgid)
1
iex> Plural.source_line_number(message, {:msgstr, 0})
