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.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.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 a usage message incorporating ‘msg’ to stderr and exit. If you override this in a subclass, it should not return – it should either exit or raise an exception.

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.
recurseinputfilelist(options)¶Use a list of files, and find a common base directory for them.
recurseinputfiles(options)¶Recurse through directories and return files to be processed.
recursiveprocess(options)¶Recurse through directories and process files.
run()¶Parses the arguments, and runs recursiveprocess with the resulting options...
set_usage(usage=None)¶sets the usage string - if usage not given, uses getusagestring for each option
seterrorleveloptions()¶Sets the errorlevel options.
setformats(formats, usetemplates)¶Sets the format options using the given format dictionary.
| Parameters: | formats (Dictionary) – The dictionary keys should be:
The dictionary values should be tuples of outputformat (string) and processor method. |
|---|
setmanpageoption()¶creates a manpage option that allows the optionparser to generate a manpage
setprogressoptions()¶Sets the progress options.

warning(msg, options=None, exc_info=None)¶Print a warning message incorporating ‘msg’ to stderr and exit.
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
translate.misc.ourdom.getnodetext(node)¶returns the node’s text by iterating through the child nodes
translate.misc.ourdom.parse(file, parser=None, bufsize=None)¶Parse a file into a DOM by filename or file object.

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.
Progress bar utilities for reporting feedback on the progress of an application.
translate.misc.progressbar.DotsProgressBar¶An ultra-simple progress indicator that just writes a dot for each action
show(verbosemessage)¶show a dot for progress :-)
translate.misc.progressbar.HashProgressBar(*args, **kwargs)¶A ProgressBar which knows how to go back to the beginning of the line.

translate.misc.quote.javapropertiesencode(source)¶Encodes source in the escaped-unicode encoding used by Java .properties files
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.
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.
