[issue26214] textwrap should minimize number of breaks in extra long words

2021-12-27 Thread Andrei Kulakov 


Andrei Kulakov  added the comment:

It may be worth fixing wrap() to do the nicer style of wrapping for long words. 
If we decide to do that, it should be done via a new parameter because the same 
logic (TextWrapper class) is used for `shorten` and in that case it may be 
preferable to have the chunk of longer word rather than cutting it out entirely.

[issue26214] textwrap should minimize number of breaks in extra long words

2020-09-04 Thread Irit Katriel 


Irit Katriel  added the comment:

To clarify, this solution is a linear-time greedy one, with three passes:
- the first pass puts each long word on its own line. 
- the second pass chops them up into words of at most width characters.
- the third pass wraps them, when there are no more long words.

This minimizes the number of breaks within words. It doesn't minimize the 
number of output lines (you'd need a dynamic programming programming algo for 
that - O(n^2)). So for this input:

wr("123 12 123456 1234", 5)

you will get 
['123', '12', '12345', '6', '1234']

where you may (or may not) have preferred:

['123', '12 1', '23456', '1234']

One more wrap: 

>>> wr(' '.join(itertools.chain(*(wr(x, 5) for x in wr("123 123 1234567 12", 
>>> width=5, break_long_words=False, 5)
['123', '123', '12345', '67 12']

Serhiy Storchaka  added the comment:

The code with nested wraps is awesome. But it does not work well.

>>> list(itertools.chain(*(wr(x, 5) for x in wr("123 123 1234567 12", width=5, 
>>> break_long_words=False
['123', '123', '12345', '67', '12']

It is expected that '67' and '12' should be in the same line: '67 12'.

Irit Katriel  added the comment:

You can do this already with the break_long_words arg of testwrap:

>>> import itertools, textwrap
>>> wr = textwrap.wrap
>>> list(itertools.chain(*(wr(x, 5) for x in wr("123 123 1234567", width=5, 
>>> break_long_words=False
['123', '123', '12345', '67']
