scalajs-scaposer

Scala.js version of scaposer.

Basic Usage

See also: xitrum-framework Scaladoc

val po = """
msgid "Hello"
msgstr "Bonjour"
"""

val result = scaposer.Parser.parse(po)
// => An Either,
// Left(scaposer.ParseFailure) or
// Right(Seq[scaposer.Translation])

Use t methods to get the translations:

val translations = result.right.get
val i18n         = scaposer.I18n(translations)
i18n.t("Hello")  // => "Bonjour"

If there's no translation, or the translation is an empty string (not translated yet), the original input is returned:

  i18n.t("Hi")  // => "Hi"

Context

val po = """
msgid "Hello"
msgstr "Bonjour"

msgctxt "Casual"
msgid "Hello"
msgstr "Salut"
"""

val translations = scaposer.Parser.parse(po).right.get
val i18n         = scaposer.I18n(translations)
i18n.tc("Casual", "Hello")  // => "Salut"

If there's no translation for the context, the translation without context is tried:

  i18n.tc("Missing context", "Hello")  // => "Bonjour"

Plural-Forms

val po = """
msgid ""
msgstr "Plural-Forms: nplurals=2; plural=n>1;"

msgid "I have one apple"
msgid_plural "I have %d apples"
msgstr[0] "J'ai une pomme"
msgstr[1] "J'ai %d pommes"
"""

val translations = scaposer.Parser.parse(po).right.get
val i18n         = scaposer.I18n(translations)
i18n.tn("I have one apple", "I have %d apples", 1)                // => "J'ai une pomme"
i18n.tn("I have one apple", "I have %d apples", 2)                // => "J'ai %d pommes"
i18n.tcn("A context", "I have one apple", "I have %d apples", 3)  // => "J'ai %d pommes"

For performance, your po file should define Plural-Forms exactly as at:

Otherwise, Scaposer cannot compare the plural form string, and it needs to parse and evaluate (slower).

Merge Po objects

You can merge multiple I18ns together.

val i18n4 = i18n1 ++ i18n2 ++ i18n3

Just like when you merge maps, translations in i18n3 will overwrite those in i18n2 will overwrite those in i18n1.
