In the spirit of Patch the Image, here's a similar challenge but with text.
Challenge
Bit rot has afflicted your precious text! Given a paragraph composed of ASCII characters, with a rectangular hole somewhere in it, your program should try to fill in the hole with appropriate text, so that the paragraph blends as best as possible.
Further definitions
- The hole will always be rectangular, and it may span multiple lines.
- There will only ever be one hole.
- Note that the hole does not necessarily fall on word boundaries (in fact, it usually won't).
- The hole will be at most 25% of the input paragraph, but may overlap or extend past the "end" of the "normal" text (see the Euclid or Badger examples below).
- Since finding the hole is not the main point of this challenge, it will be composed solely of hash marks
#
to allow for easy identification. - No other location in the input paragraph will have a hash mark.
- Your code cannot use the "normal" text in the examples below - it will only receive and process the text with the hole in it.
- The input can be as a single multi-line string, as an array of strings (one element per line), as a file, etc. -- your choice of what is most convenient for your language.
- If desired, an optional additional input detailing the coordinates of the hole can be taken (e.g., a tuple of coordinates or the like).
- Please describe your algorithm in your submission.
Voting
Voters are asked to judge the entries based on how well the algorithm fills in the text hole. Some suggestions include the following:
- Does the filled in area match the approximate distribution of spaces and punctuation as the rest of the paragraph?
- Does the filled in area introduce faulty syntax? (e.g., two spaces in a row, a period followed by a question mark, an erroneous sequence like
, ,
, etc.) - If you squint your eyes (so you're not actually reading the text), can you see where the hole used to be?
- If there aren't any CamelCase words outside the hole, does the hole contain any? If there aren't any Capitalized Letters outside the hole, does the hole contain any? If There Are A Lot Of Capitalized Letters Outside The Hole, does the hole contain a proportionate amount?
Validity Criterion
In order for a submission to be considered valid, it must not alter any text of the paragraph outside of the hole (including trailing spaces). A single trailing newline at the very end is optional.
Test Cases
Format is original paragraph in a code block, followed by the same paragraph with a hole. The paragraphs with the hole will be used for input.
1 (Patch the Image)
In a popular image editing software there is a feature, that patches (The term
used in image processing is inpainting as @minxomat pointed out.) a selected
area of an image, based on the information outside of that patch. And it does a
quite good job, considering it is just a program. As a human, you can sometimes
see that something is wrong, but if you squeeze your eyes or just take a short
glance, the patch seems to fill in the gap quite well.

But, in a larger sense, we can not dedicate, we can not consecrate, we can not
hallow this ground. The brave men, living and dead, who struggled here, have
consecrated it, far above our poor power to add or detract. The world will
little note, nor long remember what we say here, but it can never forget what
they did here. It is for us the living, rather, to be dedicated here to the
unfinished work which they who fought here have thus far so nobly advanced. It
is rather for us to be here dedicated to the great task remaining before us-
that from these honored dead we take increased devotion to that cause for which
they gave the last full measure of devotion-that we here highly resolve that
these dead shall not have died in vain-that this nation, under God, shall have
a new birth of freedom-and that government of the people, by the people, for
the people, shall not perish from the earth.

5 (Euclid's proof of the Pythagorean Theorem)
1.Let ACB be a right-angled triangle with right angle CAB.
2.On each of the sides BC, AB, and CA, squares are drawn,
CBDE, BAGF, and ACIH, in that order. The construction of
squares requires the immediately preceding theorems in Euclid,
and depends upon the parallel postulate. [footnote 14]
3.From A, draw a line parallel to BD and CE. It will
perpendicularly intersect BC and DE at K and L, respectively.
4.Join CF and AD, to form the triangles BCF and BDA.
5.Angles CAB and BAG are both right angles; therefore C, A,
and G are collinear. Similarly for B, A, and H.
6.Angles CBD and FBA are both right angles; therefore angle ABD
equals angle FBC, since both are the sum of a right angle and angle ABC.
7.Since AB is equal to FB and BD is equal to BC, triangle ABD
must be congruent to triangle FBC.
8.Since A-K-L is a straight line, parallel to BD, then rectangle
BDLK has twice the area of triangle ABD because they share the base
BD and have the same altitude BK, i.e., a line normal to their common
base, connecting the parallel lines BD and AL. (lemma 2)
9.Since C is collinear with A and G, square BAGF must be twice in area
to triangle FBC.
10.Therefore, rectangle BDLK must have the same area as square BAGF = AB^2.
11.Similarly, it can be shown that rectangle CKLE must have the same
area as square ACIH = AC^2.
12.Adding these two results, AB^2 + AC^2 = BD × BK + KL × KC
13.Since BD = KL, BD × BK + KL × KC = BD(BK + KC) = BD × BC
14.Therefore, AB^2 + AC^2 = BC^2, since CBDE is a square.
