# misc

Miscellaneous modules for translate - including modules for backward compatibility with pre-2.3 versions of Python

## autoencode

Supports a hybrid Unicode string that knows which encoding is preferable, and uses this when converting to a string.

## contextlib

Utilities for with-statement contexts. See PEP 343.

`translate.misc.contextlib.``contextmanager`(func)

  @contextmanager decorator.

  Typical usage:

      @contextmanager
      def some_generator(<arguments>):
          <setup>
          try:
              yield <value>
          finally:
              <cleanup>

  This makes this:

      with some_generator(<arguments>) as <variable>:
          <body>

  equivalent to this:

      <setup>
      try:
          <variable> = <value>
          <body>
      finally:
          <cleanup>

`translate.misc.contextlib.``nested`(*args, **kwds)

  Support multiple context managers in a single with-statement.

  Code like this:

      with nested(A, B, C) as (X, Y, Z):
          <body>

  is equivalent to this:

      with A as X:
          with B as Y:
              with C as Z:
                  <body>

class `translate.misc.contextlib.``closing`(thing)

  Context to automatically close something at the end of a block.

  Code like this:

      with closing(<module>.open(<arguments>)) as f:
          <block>

  is equivalent to this:

      f = <module>.open(<arguments>)
      try:
          <block>
      finally:
          f.close()

## context

`translate.misc.context.``with_`(mgr, body)

  A function to mimic the with statement introduced in Python 2.5

  The code below was taken from http://www.python.org/dev/peps/pep-0343/

## dictutils

Implements a case-insensitive (on keys) dictionary and order-sensitive dictionary

`translate.misc.dictutils.``generalupper`(str)

  this uses the object’s upper method - works with string and unicode

class `translate.misc.dictutils.``ordereddict`(*args)

  a dictionary which remembers its keys in the order in which they were given

  `clear`() → None. Remove all items from D.
  `copy`() → a shallow copy of D
  static `fromkeys`(S[, v]) → New dict with keys from S and values equal to v.

    v defaults to None.

  `get`(k[, d]) → D[k] if k in D, else d. d defaults to None.
  `has_key`(k) → True if D has a key k, else False
  `items`() → list of D's (key, value) pairs, as 2-tuples
  `iteritems`() → an iterator over the (key, value) items of D
  `iterkeys`() → an iterator over the keys of D
  `itervalues`() → an iterator over the values of D
  `keys`() → list of D's keys
  `pop`(key)

    remove entry from dict and internal list

  `popitem`() → (k, v), remove and return some (key, value) pair

    as a 2-tuple; but raise KeyError if D is empty

  `setdefault`(k[, d]) → D.get(k,d), also set D[k]=d if k not in D
  `update`(E) → None.

    Update D from E: for k in E.keys(): D[k] = E[k]

  `values`() → list of D's values
  `viewitems`() → a set-like object providing a view on D's items
  `viewkeys`() → a set-like object providing a view on D's keys
  `viewvalues`() → an object providing a view on D's values

## ini

Access and/or modify INI files

- Compatiable with ConfigParser
- Preserves order of sections & options
- Preserves comments/blank lines/etc
- More convenient access to data

Example:

    >>> from StringIO import StringIO
    >>> sio = StringIO('''# configure foo-application
    ... [foo]
    ... bar1 = qualia
    ... bar2 = 1977
    ... [foo-ext]
    ... special = 1''')

    >>> cfg = INIConfig(sio)
    >>> print cfg.foo.bar1
    qualia
    >>> print cfg['foo-ext'].special
    1
    >>> cfg.foo.newopt = 'hi!'

    >>> print cfg
    # configure foo-application
    [foo]
    bar1 = qualia
    bar2 = 1977
    newopt = hi!
    [foo-ext]
    special = 1

`translate.misc.ini.``readline_iterator`(f)

  iterate over a file by only using the file object’s readline method

## lru

class `translate.misc.lru.``LRUCachingDict`(maxsize, cullsize=2, peakmult=10, aggressive_gc=True, *args, **kwargs)

  Caching dictionary like object that discards the least recently used objects when number of cached items exceeds maxsize.

  cullsize is the fraction of items that will be discarded when maxsize is reached.

  `cull`()

    free memory by deleting old items from cache

  `itervaluerefs`()

    Return an iterator that yields the weak references to the values.

    The references are not guaranteed to be ‘live’ at the time they are used, so the result of calling the references needs to be checked before being used. This can be used to avoid creating references that will cause the garbage collector to keep the values around longer than needed.

  `valuerefs`()

    Return a list of weak references to the values.

    The references are not guaranteed to be ‘live’ at the time they are used, so the result of calling the references needs to be checked before being used. This can be used to avoid creating references that will cause the garbage collector to keep the values around longer than needed.

## multistring

Supports a hybrid Unicode string that can also have a list of alternate strings in the strings attribute

## optrecurse

class `translate.misc.optrecurse.``RecursiveOptionParser`(formats, usetemplates=False, allowmissingtemplate=False, description=None)

  A specialized Option Parser for recursing through directories.

  `add_option`(Option)

    add_option(opt_str, ..., kwarg=val, ...)

  `check_values`(values : Values, args : [string])

    -> (values : Values, args : [string])

    Check that the supplied option values and leftover arguments are valid. Returns the option values and leftover arguments (possibly adjusted, possibly completely new – whatever you like). Default implementation just returns the passed-in values; subclasses may override as desired.

  `checkoutputsubdir`(options, subdir)

    Checks to see if subdir under options.output needs to be created, creates if neccessary.

  `define_option`(option)

    Defines the given option, replacing an existing one of the same short name if neccessary...

  `destroy`()

    Declare that you are done with this OptionParser. This cleans up reference cycles so the OptionParser (and all objects referenced by it) can be garbage-collected promptly. After calling destroy(), the OptionParser is unusable.

  `disable_interspersed_args`()

    Set parsing to stop on the first non-option. Use this if you have a command processor which runs another command that has options of its own and you want to make sure these options don’t get confused.

  `enable_interspersed_args`()

    Set parsing to not stop on the first non-option, allowing interspersing switches with command arguments. This is the default behavior. See also disable_interspersed_args() and the class documentation description of the attribute allow_interspersed_args.

  `error`(msg : string)

    Print the usage message for the current program (self.usage) to ‘file’ (default stdout). Any occurrence of the string “%prog” in self.usage is replaced with the name of the current program (basename of sys.argv[0]). Does nothing if self.usage is empty or not defined.

  `print_version`(file : file = stdout)

    Print the version message for this program (self.version) to ‘file’ (default stdout). As with print_usage(), any occurrence of “%prog” in self.version is replaced by the current program’s name. Does nothing if self.version is empty or undefined.

  `processfile`(fileprocessor, options, fullinputpath, fulloutputpath, fulltemplatepath)

    Process an individual file.

## ourdom

module that provides modified DOM functionality for our needs

Note that users of ourdom should ensure that no code might still use classes directly from minidom, like minidom.Element, minidom.Document or methods such as minidom.parseString, since the functionality provided here will not be in those objects.

`translate.misc.ourdom.``getElementsByTagName_helper`(parent, name, dummy=None)

  A reimplementation of getElementsByTagName as an iterator.

  Note that this is not compatible with getElementsByTagName that returns a list, therefore, the class below exposes this through yieldElementsByTagName

  returns the node’s text by iterating through the child nodes

`translate.misc.ourdom.``parse`(file, parser=None, bufsize=None)

  limits the search to within tags occuring in onlysearch

`translate.misc.ourdom.``writexml_helper`(self, writer, indent='', addindent='', newl='')

  A replacement for writexml that formats it like typical XML files. Nodes are intendented but text nodes, where whitespace can be significant, are not indented.

## profiling

`translate.misc.profiling.``profile_func`(filename=None, mode='w+')

  Function/method decorator that will cause only the decorated callable to be profiled (with a `KCacheGrind` profiler) and saved to the specified file.

  Parameters:

  - filename (str) – The filename to write the profile to. If not specified the decorated function’s name is used, followed by `_func.profile`.
  - mode (str) – The mode in which to open `filename`. Default is `w+`.

## progressbar

Progress bar utilities for reporting feedback on the progress of an application.

class `translate.misc.progressbar.``DotsProgressBar`

  An ultra-simple progress indicator that just writes a dot for each action

  `show`(verbosemessage)

    show a dot for progress :-)

class `translate.misc.progressbar.``HashProgressBar`(*args, **kwargs)

  A ProgressBar which knows how to go back to the beginning of the line.

class `translate.misc.progressbar.``MessageProgressBar`(*args, **kwargs)

  A ProgressBar that just writes out the messages without any progress display

class `translate.misc.progressbar.``NoProgressBar`

  An invisible indicator that does nothing.

  `show`(verbosemessage)

    show nothing for progress :-)

class `translate.misc.progressbar.``ProgressBar`(minValue=0, maxValue=100, totalWidth=50)

  A plain progress bar that doesn’t know very much about output.

  `show`(verbosemessage)

    displays the progress bar

## quote

String processing utilities for extracting strings with various kinds of delimiters

`translate.misc.quote.``escapecontrols`(source)

  escape control characters in the given string

`translate.misc.quote.``extract`(source, startdelim, enddelim, escape=None, startinstring=False, allowreentry=True)

  Extracts a doublequote-delimited string from a string, allowing for backslash-escaping returns tuple of (quoted string with quotes, still in string at end).

`translate.misc.quote.``extractwithoutquotes`(source, startdelim, enddelim, escape=None, startinstring=False, includeescapes=True, allowreentry=True)

  Extracts a doublequote-delimited string from a string, allowing for backslash-escaping includeescapes can also be a function that takes the whole escaped string and returns the replaced version.

`translate.misc.quote.``find_all`(searchin, substr)

  Returns a list of locations where substr occurs in searchin locations are not allowed to overlap

`translate.misc.quote.``htmlentitydecode`(source)

  decodes source using HTML entities e.g. &copy; -> ©

`translate.misc.quote.``htmlentityencode`(source)

  encodes source using HTML entities e.g. © -> &copy;

`translate.misc.quote.``javapropertiesencode`(source)

  Encodes source in the escaped-unicode encoding used by Java .properties files

  Encodes source in the escaped-unicode encoding used by Mozilla .properties files.

`translate.misc.quote.``propertiesdecode`(source)

  Decodes source from the escaped-unicode encoding used by .properties files.

  Java uses Latin1 by default, and Mozilla uses UTF-8 by default.

  Since the .decode(“unicode-escape”) routine decodes everything, and we don’t want to we reimplemented the algorithm from Python Objects/unicode.c in Python and modify it to retain escaped control characters.

## sparse

simple parser / string tokenizer rather than returning a list of token types etc, we simple return a list of tokens. Each tokenizing function takes a string as input and returns a list of tokens.

exception `translate.misc.sparse.``ParserError`(parser, message, tokennum)

  Intelligent parser error

class `translate.misc.sparse.``SimpleParser`(defaulttokenlist=None, whitespacechars=' trn', includewhitespacetokens=0)

  this is a simple parser

  `applytokenizer`(inputlist, tokenizer)

    apply a tokenizer to a set of text, flattening the result

  `applytokenizers`(inputlist, tokenizers)

    apply a set of tokenizers to a set of text, flattening each time

  `findtokenpos`(tokennum)

    finds the position of the given token in the text

  `getlinepos`(tokenpos)

    finds the line and character position of the given character

  `isstringtoken`(text)

    checks whether a token is a string token

  `keeptogether`(text)

    checks whether a token should be kept together

  `raiseerror`(message, tokennum)

    raises a ParserError

  `removewhitespace`(text)

    this removes whitespace but lets it separate things out into separate tokens

  `separatetokens`(text, tokenlist=None)

    this separates out tokens in tokenlist from whitespace etc

  `stringtokenize`(text)

    makes strings in text into tokens...

  `tokenize`(source, tokenizers=None)

    tokenize the text string with the standard tokenizers

`translate.misc.sparse.``stringeval`(text)

  takes away repeated quotes (escapes) and returns the string represented by the text

`translate.misc.sparse.``stringquote`(text)

  escapes quotes as neccessary and returns a string representing the text

## stdiotell

A wrapper for sys.stdout etc that provides tell() for current position

## textwrap

Text wrapping and filling.

class `translate.misc.textwrap.``TextWrapper`(width=70, break_long_words=True)

  Object for wrapping/filling text. The public interface consists of the wrap() and fill() methods; the other methods are just there for subclasses to override in order to tweak the default behaviour. If you want to completely replace the main wrapping algorithm, you’ll probably have to override _wrap_chunks().

  Several instance attributes control various aspects of wrapping:
    width (default: 70)
      the maximum width of wrapped lines (unless break_long_words is false)
    break_long_words (default: true)
      Break words longer than ‘width’. If false, those words will not be broken, and some lines might be longer than ‘width’.
  `fill`(text : string) → string

    Reformat the single paragraph in ‘text’ to fit in lines of no more than ‘self.width’ columns, and return a new string containing the entire wrapped paragraph.

  `wrap`(text : string) → [string]

    Reformat the single paragraph in ‘text’ so it fits in lines of no more than ‘self.width’ columns, and return a list of wrapped lines. Tabs in ‘text’ are expanded with string.expandtabs(), and all other whitespace characters (including newline) are converted to space.

`translate.misc.textwrap.``wrap`(text, width=70, **kwargs)

  Wrap a single paragraph of text, returning a list of wrapped lines.

  Reformat the single paragraph in ‘text’ so it fits in lines of no more than ‘width’ columns, and return a list of wrapped lines. By default, tabs in ‘text’ are expanded with string.expandtabs(), and all other whitespace characters (including newline) are converted to space. See TextWrapper class for available keyword args to customize wrapping behaviour.

`translate.misc.textwrap.``fill`(text, width=70, **kwargs)

  Fill a single paragraph of text, returning a new string.

  Reformat the single paragraph in ‘text’ to fit in lines of no more than ‘width’ columns, and return a new string containing the entire wrapped paragraph. As with wrap(), tabs are expanded and other whitespace characters converted to space. See TextWrapper class for available keyword args to customize wrapping behaviour.

## typecheck

### doctest_support

This module allows doctest to find typechecked functions.

Currently, doctest verifies functions to make sure that their globals() dict is the __dict__ of their module. In the case of decorated functions, the globals() dict is not the right one.

To enable support for doctest do:

> import typecheck.doctest_support

This import must occur before any calls to doctest methods.

## wsgi

Wrapper to launch the bundled CherryPy server.

`translate.misc.wsgi.``launch_server`(host, port, app, **kwargs)

  Use CherryPy’s WSGI server, a multithreaded scallable server.

## wStringIO

A wrapper for cStringIO that provides more of the functions of StringIO at the speed of cStringIO

class `translate.misc.wStringIO.``CatchStringOutput`(onclose)

  catches the output before it is closed and sends it to an onclose method

  `close`()

    wrap the underlying close method, to pass the value to onclose before it goes

  `slam`()

    use this method to force the closing of the stream if it isn’t closed yet

## xml_helpers

Helper functions for working with XML.

`translate.misc.xml_helpers.``getText`(node, xml_space='preserve')

  Extracts the plain text content out of the given node.

  This method checks the xml:space attribute of the given node, and takes an optional default to use in case nothing is specified in this node.

`translate.misc.xml_helpers.``getXMLlang`(node)

  Gets the xml:lang attribute on node

`translate.misc.xml_helpers.``getXMLspace`(node, default=None)

  Gets the xml:space attribute on node

`translate.misc.xml_helpers.``namespaced`(namespace, name)

  Returns name in Clark notation within the given namespace.

  For example namespaced(“source”) in an XLIFF document might return::
    {urn:oasis:names:tc:xliff:document:1.1}source

  This is needed throughout lxml.

`translate.misc.xml_helpers.``normalize_space`(text)

  Normalize the given text for implementation of `xml:space="default"`.

`translate.misc.xml_helpers.``normalize_xml_space`(node, xml_space, remove_start=False)

  normalize spaces following the nodes xml:space, or alternatively the given xml_space parameter.

`translate.misc.xml_helpers.``setXMLlang`(node, lang)

  Sets the xml:lang attribute on node

`translate.misc.xml_helpers.``setXMLspace`(node, value)

  Sets the xml:space attribute on node

`translate.misc.xml_helpers.``string_xpath` = string()

  Return a non-normalized string in the node subtree

`translate.misc.xml_helpers.``string_xpath_normalized` = normalize-space()

  Return a (space) normalized string in the node subtree

`translate.misc.xml_helpers.``xml_preserve_ancestors` = ancestor-or-self::*[attribute::xml:space='preserve']

  All ancestors with xml:space=’preserve’

`translate.misc.xml_helpers.``xml_space_ancestors` = ancestor-or-self::*/attribute::xml:space

  All xml:space attributes in the ancestors

## xmlwrapper

  `getchild`(searchtag, tagclass=None)

    get a child with the given tag name

  `getchildren`(searchtag, tagclass=None, excludetags=[])

    get all children with the given tag name

    get some contained text

  `getvalues`(searchtag)

    get some contained values...

  `write`(file, encoding='UTF-8')

    writes the object as XML to a file...

`translate.misc.xmlwrapper.``makefixtagproc`(namespacemap)
