class `translate.storage.base.` `TranslationUnit`(source=None)

  Base class for translation units.

  Our concept of a translation unit is influenced heavily by XLIFF.

  As such most of the method- and variable names borrows from XLIFF terminology.

  A translation unit consists of the following:

  - A source string. This is the original translatable text.
  - A target string. This is the translation of the source.
  - Zero or more notes on the unit. Notes would typically be some comments from a translator on the unit, or some comments originating from the source code.
  - Zero or more locations. Locations indicate where in the original source code this unit came from.
  - Zero or more errors. Some tools (eg. `pofilter`) can run checks on translations and produce error messages.
  `adderror`(errorname, errortext)

    Adds an error message to this unit.

    Parameters: | errorname (string) – A single word to id the error. errortext (string) – The text describing the error.

  `addlocation`(location)

    Add one location to the list of locations.

    Note

    Shouldn’t be implemented if the format doesn’t support it.

  `addlocations`(location)

    Add a location or a list of locations.

    Note

    Most classes shouldn’t need to implement this, but should rather implement `TranslationUnit.addlocation()`.

    Warning

    This method might be removed in future.

  `addnote`(text, origin=None, position='append')

    Adds a note (comment).

    Parameters: | text (string) – Usually just a sentence or two. origin (string) – Specifies who/where the comment comes from. Origin can be one of the following text strings: - ‘translator’ - ‘developer’, ‘programmer’, ‘source code’ (synonyms)

  classmethod `buildfromunit`(unit)

    Build a native unit from a foreign unit, preserving as much information as possible.

  `getcontext`()

    Get the message context.

  `geterrors`()

    Get all error messages.

    Return type: | Dictionary

  `getid`()

    A unique identifier for this unit.

    Return type: | string
    Returns: | an identifier for this unit that is unique in the store

    Derived classes should override this in a way that guarantees a unique identifier for each unit in the store.

  `getlocations`()

    A list of source code locations.

    Return type: | List

    Note

    Shouldn’t be implemented if the format doesn’t support it.

  `getnotes`(origin=None)

    Returns all notes about this unit.

    It will probably be freeform text or something reasonable that can be synthesised by the format. It should not include location comments (see `getlocations()`).

  `gettargetlen`()

    Returns the length of the target string.

    Return type: | Integer

    Note

    Plural forms might be combined.

  `getunits`()

    This unit in a list.

  `hasplural`()

    Tells whether or not this specific unit has plural strings.

  `infer_state`()

    Empty method that should be overridden in sub-classes to infer the current state(_n) of the unit from its current state.

  `isblank`()

    Used to see if this unit has no source or target string.

    Note

    This is probably used more to find translatable units, and we might want to move in that direction rather and get rid of this.

  `isfuzzy`()

    Indicates whether this unit is fuzzy.

  `isheader`()

    Indicates whether this unit is a header.

  `isobsolete`()

    indicate whether a unit is obsolete

  `isreview`()

    Indicates whether this unit can be translated.

    This should be used to distinguish real units for translation from header, obsolete, binary or other blank units.

  `istranslated`()

    Indicates whether this unit is translated.

    This should be used rather than deducing it from .target, to ensure that other classes can implement more functionality (as XLIFF does).

  `makeobsolete`()

    Make a unit obsolete

  `markfuzzy`(value=True)

    Marks the unit as fuzzy or not.

  `markreviewneeded`(needsreview=True, explanation=None)

## catkeys

Manage the Haiku catkeys translation format

The Haiku catkeys format is the translation format used for localisation of the Haiku operating system.

It is a bilingual base class derived format with `CatkeysFile` and `CatkeysUnit` providing file and unit level access. The file format is described here: http://www.haiku-os.org/blog/pulkomandy/2009-09-24_haiku_locale_kit_translator_handbook

Implementation

  The implementation covers the full requirements of a catkeys file. The files are simple Tab Separated Value (TSV) files that can be read by Microsoft Excel and other spreadsheet programs. They use the .txt extension which does make it more difficult to automatically identify such files.

  The dialect of the TSV files is specified by `CatkeysDialect`.

Encoding
  The files are UTF-8 encoded.
Header
  `CatkeysHeader` provides header management support.
Escaping

  catkeys seem to escape things like in C++ (strings are just extracted from the source code unchanged, it seems.

  Functions allow for `_escape()` and `_unescape()`.

class `translate.storage.catkeys.` `CatkeysDialect`

## dtd

Classes that hold units of .dtd files (`dtdunit`) or entire files (`dtdfile`).

These are specific .dtd files for localisation used by mozilla.

Specifications

  The following information is provided by Mozilla:

  Specification

  There is a grammar for entity definitions, which isn’t really precise, as the spec says. There’s no formal specification for DTD files, it’s just “whatever makes this work” basically. The whole piece is clearly not the strongest point of the xml spec

  XML elements are allowed in entity values. A number of things that are allowed will just break the resulting document, Mozilla forbids these in their DTD parser.

Dialects

  There are two dialects:

  - Regular DTD
  - Android DTD

  Both dialects are similar, but the Android DTD uses some particular escapes that regular DTDs don’t have.

Escaping in regular DTD

  In DTD usually there are characters escaped in the entities. In order to ease the translation some of those escaped characters are unescaped when reading from, or converting, the DTD, and that are escaped again when saving, or converting to a DTD.

  In regular DTD the following characters are usually or sometimes escaped:

  - The % character is escaped using &#037; or &#37; or &#x25;
  - The ” character is escaped using &quot;
  - The ‘ character is escaped using &apos; (partial roundtrip)
  - The & character is escaped using &amp;
  - The < character is escaped using &lt; (not yet implemented)
  - The > character is escaped using &gt; (not yet implemented)

  Besides the previous ones there are a lot of escapes for a huge number of characters. This escapes usually have the form of &#NUMBER; where NUMBER represents the numerical code for the character.

  There are a few particularities in DTD escaping. Some of the escapes are not yet implemented since they are not really necessary, or because its implementation is too hard.

  A special case is the ‘ escaping using &apos; which doesn’t provide a full roundtrip conversion in order to support some special Mozilla DTD files.

  Also the ” character is never escaped in the case that the previous character is = (the sequence =” is present on the string) in order to avoid escaping the ” character indicating an attribute assignment, for example in a href attribute for an a tag in HTML (anchor tag).

Escaping in Android DTD

  It has the sames escapes as in regular DTD, plus this ones:

  - The ‘ character is escaped using &apos; or ‘ or u0027
  - The ” character is escaped using &quot;

## ical

Class that manages iCalender files for translation.

iCalendar files follow the RFC2445 specification.

The iCalendar specification uses the following naming conventions:

- Component: an event, journal entry, timezone, etc
- Property: a property of a component: summary, description, start time, etc
- Attribute: an attribute of a property, e.g. language

The following are localisable in this implementation:

- VEVENT component: SUMMARY, DESCRIPTION, COMMENT and LOCATION properties

While other items could be localised this is not seen as important until use cases arise. In such a case simply adjusting the component.name and property.name lists to include these will allow expanded localisation.

LANGUAGE Attribute
  While the iCalendar format allows items to have a language attribute this is not used. The reason being that for most of the items that we localise they are only allowed to occur zero or once. Thus ‘summary’ would ideally be present in multiple languages in one file, the format does not allow such multiple entries. This is unfortunate as it prevents the creation of a single multilingual iCalendar file.
Future Format Support
  As this format used vobject which supports various formats including vCard it is possible to expand this format to understand those if needed.

## jsonl10n

Class that manages JSON data files for translation

JSON is an acronym for JavaScript Object Notation, it is an open standard designed for human-readable data interchange.

JSON basic types:

- Number (integer or real)
- String (double-quoted Unicode with backslash escaping)
- Boolean (true or false)
- Array (an ordered sequence of values, comma-separated and enclosed in square brackets)
- Object (a collection of key:value pairs, comma-separated and enclosed in curly braces)
- null

Example:

    {
         "firstName": "John",
         "lastName": "Smith",
         "age": 25,
         "address": {
             "streetAddress": "21 2nd Street",
             "city": "New York",
             "state": "NY",
             "postalCode": "10021"
         },
         "phoneNumber": [
             {
               "type": "home",
               "number": "212 555-1234"

Manage the OmegaT glossary format

OmegaT glossary format is used by the OmegaT computer aided translation tool.

It is a bilingual base class derived format with `OmegaTFile` and `OmegaTUnit` providing file and unit level access.

Format Implementation

  The OmegaT glossary format is a simple Tab Separated Value (TSV) file with the columns: source, target, comment.

  The dialect of the TSV files is specified by `OmegaTDialect`.

Encoding

## placeables

This module implements basic functionality to support placeables.

A placeable is used to represent things like:

  1. Substitutions

     For example, in ODF, footnotes appear in the ODF XML where they are defined; so if we extract a paragraph with some footnotes, the translator will have a lot of additional XML to with; so we separate the footnotes out into separate translation units and mark their positions in the original text with placeables.

  2. Hiding of inline formatting data

     The translator doesn’t want to have to deal with all the weird formatting conventions of wherever the text came from.

  3. Marking variables

     This is an old issue - translators translate variable names which should remain untranslated. We can wrap placeables around variable names to avoid this.

The placeables model follows the XLIFF standard’s list of placeables. Please refer to the XLIFF specification to get a better understanding.

### base

Contains base placeable classes with names based on XLIFF placeables. See the XLIFF standard for more information about what the names mean.

### general

Contains general placeable implementations. That is placeables that does not fit into any other sub-category.

If the parent and offset values are not `None`, `parent.insert(offset, deleted)` effectively undoes the delete.

    Returns: | The transformed Unicode string representing the sub-tree.

## php

Classes that hold units of PHP localisation files `phpunit` or entire files `phpfile`. These files are used in translating many PHP based applications.

Only PHP files written with these conventions are supported:

    <?php
    $lang['item'] = "vale";  # Array of values
    $some_entity = "value";  # Named variables
    define("ENTITY", "value");
    $lang = array(
       'item1' => 'value1'    ,   #Supports space before comma
       'item2' => 'value2',
    );
    $lang = array(    # Nested arrays
       'item1' => 'value1',
       'item2' => array(
          'key' => 'value'    ,   #Supports space before comma
          'key2' => 'value2',
       ),
    );

Nested arrays without key for nested array are not supported:

    <?php
    $lang = array(array('key' => 'value'));

The working of PHP strings and specifically the escaping conventions which differ between single quote (‘) and double quote (“) characters are implemented as outlined in the PHP documentation for the String type.

  Convert PHP escaped string to a Python string.

`translate.storage.php.` `phpencode`(text, quotechar="'")

## properties

Classes that hold units of .properties, and similar, files that are used in translating Java, Mozilla, MacOS and other software.

The `propfile` class is a monolingual class with `propunit` providing unit level access.

The .properties store has become a general key value pair class with `Dialect` providing the ability to change the behaviour of the parsing and handling of the various dialects.

Currently we support:

- Java .properties
- Mozilla .properties
- Adobe Flex files
- MacOS X .strings files
- Skype .lang files

The following provides references and descriptions of the various dialects supported:

Java

  Java .properties are supported completely except for the ability to drop pairs that are not translated.

  The following .properties file description gives a good references to the .properties specification.

  Properties file may also hold Java MessageFormat messages. No special handling is provided in this storage class for MessageFormat, but this may be implemented in future.

  All delimiter types, comments, line continuations and spaces handling in delimeters are supported.

Mozilla
  Mozilla files use ‘=’ as a delimiter, are UTF-8 encoded and thus don’t need u escaping. Any U values will be converted to correct Unicode characters.
Strings
  Mac OS X strings files are implemented using these two articles as references.
Flex
  Adobe Flex files seem to be normal .properties files but in UTF-8 just like Mozilla files. This page provides the information used to implement the dialect.
Skype
  Skype .lang files seem to be UTF-16 encoded .properties files.

A simple summary of what is permissible follows.

Comments supported:

    # a comment
    // a comment (only at the beginning of a line)

    # The following are # escaped to render in docs
    # ! is standard but not widely supported
    #! a comment
    # /* is non-standard but used on some implementations
    #/* a comment (not across multiple lines) */

Name and Value pairs:

    # Delimiters
    key = value
    key : value
    # Whitespace delimiter
    # key[sp]value

    # Space in key and around value
    \ key\ = \ value

    # Note that the b and c are escaped for reST rendering
    b = a string with escape sequences \t \n \r \\ \" \' \ (space) \u0123
    c = a string with a continuation line \
        continuation line

    # Special cases
    # key with no value
    //key (escaped; doesn't render in docs)
    # value no key (extractable in prop2po but not mergeable in po2prop)
    =value

    # .strings specific
    "key" = "value";

## qm

Module for parsing Qt .qm files.

Note

Based on documentation from Gettext’s .qm implementation (see write-qt.c) and on observation of the output of lrelease.

Note

Certain deprecated section tags are not implemented. These will break and print out the missing tag. They are easy to implement and should follow the structure in 03 (Translation). We could find no examples that use these so we’d rather leave it unimplemented until we actually have test data.

Note

Many .qm files are unable to be parsed as they do not have the source text. We assume that since they use a hash table to lookup the data there is actually no need for the source text. It seems however that in Qt4’s lrelease all data is included in the resultant .qm file.

Note

We can only parse, not create, a .qm file. The main issue is that we need to implement the hashing algorithm (which seems to be identical to the Gettext hash algorithm). Unlike Gettext it seems that the hash is required, but that has not been validated.

Note

The code can parse files correctly. But it could be cleaned up to be more readable, especially the part that breaks the file into sections.

## tiki

Class that manages TikiWiki files for translation. Tiki files are <strike>ugly and inconsistent</strike> formatted as a single large PHP array with several special sections identified by comments. Example current as of 2008-12-01:

    <?php
      // Many comments at the top
      $lang=Array(
      // ### Start of unused words
      "aaa" => "zzz",
      // ### end of unused words

      // ### start of untranslated words
      // "bbb" => "yyy",
      // ### end of untranslated words

      // ### start of possibly untranslated words
      "ccc" => "xxx",
      // ### end of possibly untranslated words

      "ddd" => "www",
      "###end###"=>"###end###");
    ?>

In addition there are several auto-generated //-style comments scattered through the page and array, some of which matter when being parsed.

## utx

Manage the Universal Terminology eXchange (UTX) format

UTX is a format for terminology exchange, designed it seems with Machine Translation (MT) as it’s primary consumer. The format is created by the Asia-Pacific Association for Machine Translation (AAMT).

It is a bilingual base class derived format with `UtxFile` and `UtxUnit` providing file and unit level access.

The format can manage monolingual dictionaries but these classes don’t implement that.

Specification
  The format is implemented according to UTX v1.0 (No longer available from their website. The current UTX version may be downloaded instead).
Format Implementation
  The UTX format is a Tab Seperated Value (TSV) file in UTF-8. The first two lines are headers with subsequent lines containing a single source target definition.
Encoding
  The files are UTF-8 encoded with no BOM and CR+LF line terminators.

## versioncontrol

This module manages interaction with version control systems.

To implement support for a new version control system, inherit from `GenericRevisionControlSystem`.

TODO:
  - Add authentication handling
  - `commitdirectory()` should do a single commit instead of one for each file
  - Maybe implement some caching for `get_versioned_object()` - check profiler

`translate.storage.versioncontrol.` `DEFAULT_RCS` = ['svn', 'cvs', 'darcs', 'git', 'bzr', 'hg']

  the names of all supported revision control systems

  modules of the same name containing a class with the same name are expected to be defined below ‘translate.storage.versioncontrol’

class `translate.storage.versioncontrol.` `GenericRevisionControlSystem`(location, oldest_parent=None)

  Bases: `object`

  The super class for all version control classes.

  Always inherit from this class to implement another RC interface.

  At least the two attributes `RCS_METADIR` and `SCAN_PARENTS` must be overriden by all implementations that derive from this class.

  By default, all implementations can rely on the following attributes:
    - `root_dir`: the parent of the metadata directory of the working copy
    - `location_abs`: the absolute path of the RCS object
    - `location_rel`: the path of the RCS object relative to `root_dir`
  `RCS_METADIR` = None

    The name of the metadata directory of the RCS

    e.g.: for Subversion -> “.svn”

  `SCAN_PARENTS` = None

    Whether to check the parent directories for the metadata directory of the RCS working copy

    Some revision control systems store their metadata directory only in the base of the working copy (e.g. bzr, GIT and Darcs) use `True` for these RCS

    Other RCS store a metadata directory in every single directory of the working copy (e.g. Subversion and CVS) use `False` for these RCS

## wordfast

Manage the Wordfast Translation Memory format

Wordfast TM format is the Translation Memory format used by the Wordfast computer aided translation tool.

It is a bilingual base class derived format with `WordfastTMFile` and `WordfastUnit` providing file and unit level access.

Wordfast is a computer aided translation tool. It is an application built on top of Microsoft Word and is implemented as a rather sophisticated set of macros. Understanding that helps us understand many of the seemingly strange choices around this format including: encoding, escaping and file naming.

Implementation

  The implementation covers the full requirements of a Wordfast TM file. The files are simple Tab Separated Value (TSV) files that can be read by Microsoft Excel and other spreadsheet programs. They use the .txt extension which does make it more difficult to automatically identify such files.

  The dialect of the TSV files is specified by `WordfastDialect`.

Encoding

  The files are UTF-16 or ISO-8859-1 (Latin1) encoded. These choices are most likely because Microsoft Word is the base editing tool for Wordfast.

  The format is tab separated so we are able to detect UTF-16 vs Latin-1 by searching for the occurance of a UTF-16 tab character and then continuing with the parsing.

Timestamps
  `WordfastTime` allows for the correct management of the Wordfast YYYYMMDD~HHMMSS timestamps. However, timestamps on individual units are not updated when edited.
Header
  `WordfastHeader` provides header management support. The header functionality is fully implemented through observing the behaviour of the files in real use cases, input from the Wordfast programmers and public documentation.
Escaping

  Wordfast TM implements a form of escaping that covers two aspects:

  1. Placeable: bold, formating, etc. These are left as is and ignored. It is up to the editor and future placeable implementation to manage these.
  2. Escapes: items that may confuse Excel or translators are escaped as `&'XX;`. These are fully implemented and are converted to and from Unicode. By observing behaviour and reading documentation we where able to observe all possible escapes. Unfortunately the escaping differs slightly between Windows and Mac version. This might cause errors in future. Functions allow for `<_wf_to_char>` and back to Wordfast escape (`<_char_to_wf>`).
Extended Attributes
  The last 4 columns allow users to define and manage extended attributes. These are left as is and are not directly managed byour implemenation.

  The tab t character as it would appear in UTF-16 encoding

## workflow

A workflow is defined by a set of states that a translation unit can be in and the (allowed) transitions between these states. A state is defined by a range between -128 and 127, indicating its level of “completeness”. The range is closed at the beginning and open at the end. That is, if a workflow contains states A, B and C where A < B < C, a unit with state number n is in state A if A <= n < B, state B if B <= n < C or state C if C <= n < MAX.

A value of 0 is typically the “empty” or “new” state with negative values reserved for states like “obsolete” or “do not use”.

Format specific workflows should be defined in such a way that the numeric state values correspond to similar states. For example state 0 should be “untranslated” in PO and “new” or “empty” in XLIFF, state 100 should be “translated” in PO and “final” in XLIFF. This allows formats to implicitly define similar states.

class `translate.storage.xml_extract.extract.` `Translatable`(placeable_name, xpath, dom_node, source, is_inline=False)

  A node corresponds to a translatable element. A node may have children, which correspond to placeables.

  `has_translatable_text`

    Check if it contains any chunk of text with more than whitespace.

    If not, then there’s nothing to translate.

`translate.storage.xml_extract.extract.` `build_idml_store`(odf_file, store, parse_state, store_adder=None)

  Any translatable content present in a child node is treated as a placeable.

### generate

`translate.storage.xml_extract.generate.` `find_dom_root`(parent_dom_node, dom_node)

  See also

  `find_placeable_dom_tree_roots()`

`translate.storage.xml_extract.generate.` `find_placeable_dom_tree_roots`(unit_node)

  For an inline placeable, find the root DOM node for the placeable in its parent.

  Consider the diagram. In this pseudo-ODF example, there is an inline span element. However, the span is contained in other tags (which we never process). When splicing the template DOM tree (that is, the DOM which comes from the XML document we’re using to generate a translated XML document), we’ll need to move DOM sub-trees around and we need the roots of these sub-trees:

      <p> This is text \/                <- Paragraph containing an inline placeable
                       <blah>            <- Inline placeable's root (which we want to find)
                       ...               <- Any number of intermediate DOM nodes
                       <span> bold text  <- The inline placeable's Translatable
                                            holds a reference to this DOM node

`translate.storage.xml_extract.generate.` `get_xliff_source_target_doms`(unit)

  Return a tuple with unit source and target DOM objects.

  This method is method is meant to provide a way to retrieve the DOM objects for the unit source and target for XLIFF stores.

`translate.storage.xml_extract.generate.` `replace_dom_text`(make_parse_state, dom_retriever=<function get_xliff_source_target_doms>, process_translatable=<function process_translatable>)

  Return a function:

      action: etree_Element x base.TranslationUnit -> None

  which takes a dom_node and a translation unit. The dom_node is rearranged according to rearrangement of placeables in unit.target (relative to their positions in unit.source).

### misc

`translate.storage.xml_extract.misc.` `compose_mappings`(left, right)

  Given two mappings left: A -> B and right: B -> C, create a hash result_map: A -> C. Only values in left (i.e. things from B) which have corresponding keys in right will have their keys mapped to values in right.

`translate.storage.xml_extract.misc.` `parse_tag`(full_tag)

      >>> parse_tag('{urn:oasis:names:tc:opendocument:xmlns:office:1.0}document-content')
      ('urn:oasis:names:tc:opendocument:xmlns:office:1.0', 'document-content')
      >>> parse_tag('document-content')
      ('', 'document-content')

`translate.storage.xml_extract.misc.` `reduce_tree`(f, parent_unit_node, unit_node, get_children, *state)

  Enumerate a tree, applying f to in a pre-order fashion to each node.

  parent_unit_node contains the parent of unit_node. For the root of the tree, parent_unit_node == unit_node.

  get_children is a single argument function applied to a unit_node to get a list/iterator to its children.

  state is used by f to modify state information relating to whatever f does to the tree.

### unit_tree

`translate.storage.xml_extract.unit_tree.` `build_unit_tree`(store, filename=None)

  Enumerate a translation store and build a tree with XPath components as nodes and where a node contains a unit if a path from the root of the tree to the node containing the unit, is equal to the XPath of the unit.

  The tree looks something like this:

      root
         `- ('document-content', 1)
            `- ('body', 2)
               |- ('text', 1)
               |  `- ('p', 1)
               |     `- <reference to a unit>
               |- ('text', 2)
               |  `- ('p', 1)
               |     `- <reference to a unit>
               `- ('text', 3)
                  `- ('p', 1)
                     `- <reference to a unit>

### xpath_breadcrumb

class `translate.storage.xml_extract.xpath_breadcrumb.` `XPathBreadcrumb`

  A class which is used to build XPath-like paths as a DOM tree is walked. It keeps track of the number of times which it has seen a certain tag, so that it will correctly create indices for tags.

  Initially, the path is empty. Thus >>> xb = XPathBreadcrumb() >>> xb.xpath “”

  Suppose we walk down a DOM node for the tag <foo> and we want to record this, we simply do >>> xb.start_tag(‘foo’)

  Now, the path is no longer empty. Thus >>> xb.xpath foo[0]

  Now suppose there are two <bar> tags under the tag <foo> (that is <foo><bar></bar><bar></bar><foo>), then the breadcrumb will keep track of the number of times it sees <bar>. Thus

      >>> xb.start_tag('bar')
      >>> xb.xpath
      foo[0]/bar[0]
      >>> xb.end_tag()
      >>> xb.xpath
      foo[0]
      >>> xb.start_tag('bar')
      >>> xb.xpath
      foo[0]/bar[1]

## xml_name

class `translate.storage.xml_name.` `XmlNamer`(dom_node)

  Initialize me with a DOM node or a DOM document node (the toplevel node you get when parsing an XML file). Then use me to generate fully qualified XML names.

      >>> xml = '<office:document-styles xmlns:office="urn:oasis:names:tc:opendocument:xmlns:office:1.0"></office>'
      >>> from lxml import etree
      >>> namer = XmlNamer(etree.fromstring(xml))
      >>> namer.name('office', 'blah')
      {urn:oasis:names:tc:opendocument:xmlns:office:1.0}blah
      >>> namer.name('office:blah')
      {urn:oasis:names:tc:opendocument:xmlns:office:1.0}blah

  I can also give you XmlNamespace objects if you give me the abbreviated namespace name. These are useful if you need to reference a namespace continuously.

      >>> office_ns = name.namespace('office')
      >>> office_ns.name('foo')
      {urn:oasis:names:tc:opendocument:xmlns:office:1.0}foo
