NAME
services.xml - libtranslate generic service definitions
DESCRIPTION
The services.xml file contains translation service definitions for the libtranslate
generic module.
The generic module provides an abstract framework for supporting web-based translation
services.
When the generic module is initialized, it reads service definitions from the services.xml
files located in /usr/share/libtranslate and ~/.libtranslate, creates the services defined
in these files, and makes them available to libtranslate.
The services.xml file must be encoded in UTF-8, and conform to the services.xml Document
Type Definition, located in /usr/share/libtranslate/services.dtd.
ELEMENTS
services
Description
The services element is the root of the document, and may contains service
definitions and language mappings.
Children
These elements may occur zero or more times in services: custom-language, service.
custom-language
Description
The custom-language element maps a RFC 3066 language tag to a language name.
Note
Some RFC 3066 tag to name mappings are built into libtranslate and do not need to
be added (see the Built-In RFC 3066 Tag to Name Mappings appendix in the
libtranslate Reference Manual).
Attributes
tag (required)
The RFC 3066 language tag.
name (required)
The language human-readable name.
Parents
This element contains custom-language: services.
service
Description
The service element defines a translation service.
Attributes
name (required)
The service symbolic name, encoded in ASCII.
nick (implied, default: name)
The service human-readable name.
max-chunk-len (optional, default: 1000)
The maximum length of an input chunk, in characters (0 means unlimited).
Parents
This element contains service: services.
Children
This element may occur zero or more times in service: group.
group
Description
The group element defines a translation group (a group represents a set of
languages and translation methods).
Parents
This element contains group: service.
Children
These elements may occur zero or more times in group: language, http-header.
These elements may occur zero or one time in group: text-translation,
web-page-translation.
language
Description
The language element adds a language to the list of languages supported by a group.
Attributes
tag (required)
The RFC 3066 language tag.
service-tag (implied, default: tag)
The language service-specific tag. This tag is not exposed to libtranslate,
but is available as from and to variables (see Variable Substitution).
to (optional, default: none)
A comma-separated list of RFC 3066 language tags this language can be
translated into. The special list element * means "every language of this
group but this one".
Parents
This element contains language: group.
http-header
Description
The http-header element adds a HTTP header to the list of headers that are set when
a HTTP request is issued.
If the http-header element occurs inside a group element, the header is added for
text and web page translations.
If it occurs inside a text-translation or web-page-translation element, the header
is only added for a text or web page translation, respectively.
Attributes
name (required)
The HTTP header name.
value (required)
The HTTP header value.
Parents
These elements contain http-header: group, text-translation, web-page-translation.
text-translation
Description
The presence of the text-translation element specifies that the group can translate
text.
Attributes
url (required)
The URL to use for translating text. Variable substitution is performed on
the URL (see Variable Substitution).
post (optional, default: none)
If this attribute is present, a HTTP POST request is issued (using the
attribute value as post data). Otherwise, a HTTP GET request is issued.
Variable substitution is performed on the post data (see Variable
Substitution).
Parents
This element contains text-translation: group.
Children
These element may occur zero or more times in text-translation: http-header,
pre-marker, error-marker.
This element may occur zero or one time in text-translation: post-marker.
pre-marker
Description
The pre-marker element is used to extract the translated text from the response to
a text translation request.
For each pre-marker element, the parser locates text in the server response. If
text is found, the parser moves to the character following text. If it is not
found, the translation fails. The translated text starts at the character following
the last pre-marker match. If no pre-marker element is specified, the translated
text starts at the first character of the server response.
Attributes
text (required)
The text to match.
Parents
This element contains pre-marker: text-translation.
post-marker
Description
The post-marker element is used to extract the translated text from the response to
a text translation request.
If text can be located in the server response, the translated text ends at the
character preceding text. Otherwise, the translation fails. If no post-marker
element is specified, the translated text ends at the last character of the server
response.
Attributes
text (required)
The text to match.
Parents
This element contains post-marker: text-translation.
error-marker
Description
The error-marker element is used to check if a text translation error has occurred.
If one or more error-marker elements are specified and the text of any of them can
be located anywhere in the server response, the translation fails.
Attributes
text (required)
The text to match.
Parents
This element contains error-marker: text-translation.
web-page-translation
Description
The presence of the web-page-translation element specifies that the group can
translate a web page.
If no http-header element is specified and if post is not specified, the generic
module does not need to connect to the server. In this case, url is returned as the
URL of the translated web page. Otherwise, the generic module connects to the
server, issues a HTTP GET or POST request, saves the response to a local file, and
returns a file:// URL pointing to that file.
Attributes
url (required)
The URL to use for translating a web page. Variable substitution is
performed on the URL (see Variable Substitution).
post (optional, default: none)
If this attribute is present, a HTTP POST request is issued (using the
attribute value as post data). Otherwise, a HTTP GET request is issued (or
no request at all, see above). Variable substitution is performed on the
post data (see Variable Substitution).
Parents
This element contains web-page-translation: group.
Children
This element may occur zero or more times in web-page-translation: http-header.
VARIABLE SUBSTITUTION
Variable substitution is performed at translation time on the url and post attributes of
the text-translation and web-page-translation elements.
A variable has the syntax ${varname[:modifiers]}.
varname may be any of the following variables:
text (text-translation only)
The text to translate.
url (web-page-translation only)
The URL of the web page to translate.
from The source language service tag.
to The destination language service tag.
time The number of seconds since 0 hours, 0 minutes, 0 seconds, January 1, 1970,
Coordinated Universal Time.
modifiers is a comma-separated list of modifiers. Each modifier is applied (in the
specified order) on the contents of the variable. A modifier has the syntax name[=value].
name may be any of the following modifiers:
escape Escapes the unsafe characters in the variable using URI percent notation.
charset
Converts the variable from UTF-8 (the libtranslate character set) to the character
set value.
