string_formatter 1.0.1

replacement for string.Formatter supporting empy keys (recursively)

This package is a backport of string.Formatter and its tests to Python 2.7 and 3.3 (and 3.4.0 as shipping with Ubuntu 14.04 LTS/Linux Mint 17)

It allows empty keys in format strings as introduced in Python 3.4.1, and fixes a bug ( "{:<{}} {}" ) when using nested empty keys, that is available in all versions of string.Formatter() allowing empty keys (up to at least 3.5.0rc3).

Usage

The package can be used as a replacement for string:

import string_formatter as string

TrailingFormatter

Additionally this package includes TrailingFormatter allow a type specification t with a single character parameter, that will be added to the (stringified) value before applying (left-aligned) formatting:

import string_formatter as string

fmt = string.TrailingFormatter()
d = dict(a=1, bc=2, xyz=18)
for key in sorted(d):
    print(fmt.format("{:t{}<{}} {:>3}", key, ':', 15, d[key]))

giving:

a:                1
bc:               2
xyz:             18
