This filter changes all words to Title Caps, and attempts to be clever about SMALL words like a/an/the in the input.

The list of "SMALL words" which are not capped comes from the New York Times Manual of Style, plus some others like 'vs' and 'v'.

This is a resurrection of Stuart Colville's, which was in turn a port of John Gruber's

The easiest method is to simply use pip:

(sudo) pip install titlecase


Titlecase provides only one function, simply:

>>> from titlecase import titlecase
>>> titlecase('a thing')
'A Thing'

A callback function may also be supplied, which will be called for every word:

>>> def abbreviations(word, **kwargs):
...   if word.upper() in ('TCP', 'UDP'):
...     return word.upper()
>>> titlecase.titlecase('a simple tcp and udp wrapper', callback=abbreviations)
'A Simple TCP and UDP Wrapper'

The callback function is supplied with an all_caps keyword argument, indicating whether the entire line of text was entirely capitalized. Returning None from the callback function will allow titlecase to process the word as normal.

Command Line Usage

Titlecase also provides a command line utility titlecase:

$ titlecase make me a title
Make Me a Title
$ echo "Can pipe and/or whatever else" | titlecase
Can Pipe and/or Whatever Else
# Or read/write files:
$ titlecase -f infile -o outfile
