Miscellaneous modules for translate - including modules for backward compatibility with pre-2.3 versions of Python
Implements a case-insensitive (on keys) dictionary and order-sensitive dictionary
translate.misc.dictutils.cidict(fromdict=None)¶clear() → None. Remove all items from D.¶copy() → a shallow copy of D¶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(k[, d]) → v, remove specified key and return the corresponding value.¶If key is not found, d is returned if given, otherwise KeyError is raised
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¶translate.misc.file_discovery.get_abs_data_filename(path_parts, basedirs=None)¶Get the absolute path to the given file- or directory name in the current running application’s data directory.
| Parameters: | path_parts (list) – The path parts that can be joined by os.path.join(). |
|---|
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.
Supports a hybrid Unicode string that can also have a list of alternate strings in the strings attribute
translate.misc.multistring.multistring(*args, **kwargs)¶capitalize() → unicode¶Return a capitalized version of S, i.e. make the first character have upper case and the rest lower case.
center(width[, fillchar]) → unicode¶Return S centered in a Unicode string of length width. Padding is done using the specified fill character (default is a space)
count(sub[, start[, end]]) → int¶Return the number of non-overlapping occurrences of substring sub in Unicode string S[start:end]. Optional arguments start and end are interpreted as in slice notation.
decode([encoding[, errors]]) → string or unicode¶Decodes S using the codec registered for encoding. encoding defaults to the default encoding. errors may be given to set a different error handling scheme. Default is ‘strict’ meaning that encoding errors raise a UnicodeDecodeError. Other possible values are ‘ignore’ and ‘replace’ as well as any other name registered with codecs.register_error that is able to handle UnicodeDecodeErrors.
encode([encoding[, errors]]) → string or unicode¶Encodes S using the codec registered for encoding. encoding defaults to the default encoding. errors may be given to set a different error handling scheme.

lower() → unicode¶Return a copy of the string S converted to lowercase.
lstrip([chars]) → unicode¶Return a copy of the string S with leading whitespace removed. If chars is given and not None, remove characters in chars instead. If chars is a str, it will be converted to unicode before stripping

replace(old, new[, count]) → unicode¶Return a copy of S with all occurrences of substring old replaced by new. If the optional argument count is given, only the first count occurrences are replaced.
rfind(sub[, start[, end]]) → int¶Return the highest index in S where substring sub is found, such that sub is contained within S[start:end]. Optional arguments start and end are interpreted as in slice notation.
Return -1 on failure.
rindex(sub[, start[, end]]) → int¶Like S.rfind() but raise ValueError when the substring is not found.
rjust(width[, fillchar]) → unicode¶Return S right-justified in a Unicode string of length width. Padding is done using the specified fill character (default is a space).
rpartition(sep) -> (head, sep, tail)¶Search for the separator sep in S, starting at the end of S, and return the part before it, the separator itself, and the part after it. If the separator is not found, return two empty strings and S.
rsplit([sep[, maxsplit]]) → list of strings¶Return a list of the words in S, using sep as the delimiter string, starting at the end of the string and working to the front. If maxsplit is given, at most maxsplit splits are done. If sep is not specified, any whitespace string is a separator.
rstrip([chars]) → unicode¶Return a copy of the string S with trailing whitespace removed. If chars is given and not None, remove characters in chars instead. If chars is a str, it will be converted to unicode before stripping
split([sep[, maxsplit]]) → list of strings¶Return a list of the words in S, using sep as the delimiter string. If maxsplit is given, at most maxsplit splits are done. If sep is not specified or is None, any whitespace string is a separator and empty strings are removed from the result.

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.

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.

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.mozillaescapemarginspaces(source)¶Escape leading and trailing spaces for 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.
