NAME
translate - translate a text or web page
SYNOPSIS
translate {-? | -v | --list-services}
translate [-s services] [-f lang] [-t lang] {-l}
translate [-s services] [-f lang] [-t lang] {http_url | https_url}
translate [-s services] [-f lang] [-t lang] [--max-threads=n]
[--max-retries=n] [file]
DESCRIPTION
translate translates a text or web page.
If the first synopsis form is used, translate prints a quick help, the
version information or the list of available translation services to
standard output.
If the second synopsis form is used, translate prints the list of
available language pairs to standard output.
If the third synopsis form is used, translate translates the web page
pointed to by http_url or https_url, and prints the URL of the
translated web page to standard output (http_url must be a string
starting with http://, and https_url must be a string starting with
https://).
If the fourth synopsis form is used, translate translates the text
contained in file, and prints the translation to standard output (if
file is omitted or given as a single dash, standard input is used
instead).
OPTIONS
-?, --help
Prints a quick help to standard output.
-v, --version
Prints version information to standard output.
--list-services
Lists the available translation services.
-s services, --services=services
Specifies the translation services to use. The services argument
must be a comma-separated list of service names (default value:
all the available services).
The list of services determines the available language pairs.
The order of the list is important, as libtranslate iterates
over the list until the requested translation can be performed.
-l, --list-pairs
Lists the available language pairs.
The -f and -t options can be used to specify a source and/or
destination language filter. If neither -f nor -t is specified,
all the pairs are listed.
-f lang, --from=lang
Specifies the source language of a translation. The lang
argument must be a RFC 3066 language tag such as en or zh-TW
(default value: see Language Selection).
-t lang, --to=lang
Specifies the destination language of a translation. The lang
argument must be a RFC 3066 language tag such as en or zh-TW
(default value: see Language Selection).
--max-threads=n
Specifies the maximum number of concurrent threads to use for
translating text (default value: 8).
--max-retries=n
Specifies the maximum number of retries per text chunk (default
value: 3).
LANGUAGE SELECTION
Definitions: in this section, default_from is defined as the contents
of the environment variable TRANSLATE_DEFAULT_FROM, or, if that
variable is not set, en; default_to is defined as the contents of the
environment variable TRANSLATE_DEFAULT_TO, or, if that variable is not
set, fr.
If the source language is not specified, it defaults to default_from,
or, if the destination language is equal to default_from, default_to.
If the destination language is not specified, it defaults to
default_to, or, if the source language is equal to default_to,
default_from.
CHARACTER SET HANDLING
Internally, libtranslate uses the UTF-8 encoding.
If the input text is not encoded in UTF-8, translate assumes it is
encoded in the character set of the current locale, and attempts to
convert it to UTF-8. If the conversion fails, translate exits with an
error.
The output text is converted to the character set of the current locale
before printing.
EXAMPLES
In the following examples, it is assumed that TRANSLATE_DEFAULT_FROM is
set to es and that TRANSLATE_DEFAULT_TO is set to de.
translate -f fr -l
Lists all the available language pairs where the source language
is French.
translate document1
Translates the contents of the file document1 from Spanish to
German and prints the result to standard output.
translate -s babelfish,freetranslation document1
Translates the contents of the file document1 from Spanish to
German, only using the Babel Fish and FreeTranslation services,
and prints the result to standard output.
translate -f de document1
Translates the contents of the file document1 from German to
Spanish and prints the result to standard output.
echo "Le problème est résolu." | translate -f fr -t en
Translates the text given on standard input from French to
English and prints the result to standard output.
translate -t en http://www.freebsd.org/es/index.html
Translates the web page pointed to by
http://www.freebsd.org/es/index.html from Spanish to English and
prints an URL pointing to the result to standard output.
