babel.util

Various utility classes and functions.

distinct(iterable)

Yield all items in an iterable collection that are distinct.

Unlike when using sets for a similar effect, the original ordering of the items in the collection is preserved by this function.

>>> print list(distinct([1, 2, 1, 3, 4, 4]))
[1, 2, 3, 4]
>>> print list(distinct('foobar'))
['f', 'o', 'b', 'a', 'r']

param iterable:	the iterable collection providing the data
return:	the distinct items in the collection
rtype:	iterator

parse_encoding(fp)

Deduce the encoding of a source file from magic comment.

It does this in the same way as the Python interpreter

The fp argument should be a seekable file object.

(From Jeff Dairiki)

pathmatch(pattern, filename)

Extended pathname pattern matching.

This function is similar to what is provided by the fnmatch module in the Python standard library, but:

• can match complete (relative or absolute) path names, and not just file names, and
• also supports a convenience pattern ("**") to match files at any directory level.

Examples:

>>> pathmatch('**.py', 'bar.py')
True
>>> pathmatch('**.py', 'foo/bar/baz.py')
True
>>> pathmatch('**.py', 'templates/index.html')
False

>>> pathmatch('**/templates/*.html', 'templates/index.html')
True
>>> pathmatch('**/templates/*.html', 'templates/foo/bar.html')
False

param pattern:	the glob pattern
param filename:	the path name of the file to match against
return:	True if the path name matches the pattern, False otherwise
rtype:	bool

TextWrapper

(Not documented)

wraptext(text, width=70, initial_indent='', subsequent_indent='')

Simple wrapper around the textwrap.wrap function in the standard library. This version does not wrap lines on hyphens in words.

param text:	the text to wrap
param width:	the maximum line width
param initial_indent:
	string that will be prepended to the first line of wrapped output
param subsequent_indent:
	string that will be prepended to all lines save the first of wrapped output
return:	a list of lines
rtype:	list
