REGEX: a single line should contain each word in a paragraph.

[Vasile Caraus]

as seen below, each line in all the paraphrases is unfinished. The words at the beginning of each line in the paragraph are not a continuation of the previous line. I’m interested in connecting all the lines in the paraphrase without having any word breaks.

When the water rises up to F, the piece at A will be visible; when it
reaches G, both A and B will be visible; and when it comes up to H,
all three pieces will be visible.


_Artificial Earthquake and Volcano._

Grind an equal quantity of fresh iron filings with pure sulphur, till
the whole be reduced to a fine powder. Be careful not to let any wet
come near it. Then bury about thirty pounds of it a foot deep in the
earth, and in about six or eight hours the ground will heave and
swell, and shortly after send forth smoke and flames like a burning
mountain. If the earth is raised in a conical shape, it will be no bad
miniature resemblance of one of the burning mountains.


_Artificial Illuminations._

A very pleasing exhibition may be made with very little trouble or
expense, in the following manner: Provide a box, which you fit up with
architectural designs cut out on pasteboard; prick small holes in
those parts of the building where you wish the illuminations to
appear, observing, that in proportion to the perspective, the holes
are to be made smaller; and on the near objects the holes are to be
made larger. Behind these designs thus perforated, you fix a lamp or
candle, but in such a manner that the reflection of the light shall
only shine through the holes; then placing a light of just sufficient
brilliance to show the design of the buildings before it, and making a
hole for the sight at the front end of the box, you will have a very
tolerable representation of illuminated buildings.

THE OUTPUT

When the water rises up to F, the piece at A will be visible; when it reaches G, both A and B will be visible; and when it comes up to H, all three pieces will be visible.

My regex doesn’t work very good:

FIND: ^(.*?)$(\K.*)\r

REPLACE BY: \2

OR (a better one)

FIND: ^(.*?)$(\R)

REPLACE BY: \1

[wonkawilly]

Can you show the end line char that separates a line with the next one? Usually You could have one of the following:

\r\n
\r
\n

For example you could do something like:

find: \r\n\r\n
replace: §§

then:
find: \r\n
replace: " " [just a space without quotes]

then back:
find: §§
replace: \r\n\r\n

[Coises]

Find: ([^\r\n])\R([^\r\n])
Replace: \1 \2

[Vasile Caraus]

@Coises very good answer, thanks a lot !

Find what: \R+_.+_\R+(*SKIP)(*FAIL)|\R

Replace with: LEAVE A BLANK SPACE

[guy038]

Hello, @Vasile-caraus, @wonkawilly, @coises and All,

@vasile-caraus, an alternate and more simple solution could be :

• SEARCH (?-s)(?<=.)\R(?=.)

• REPLACE \x20

Best Regards,

[Vasile Caraus]

Search: (?<=[^\r\n])\r?\n(?=[^\r\n])

Replace by: leave an empy space

[Paul Wormer]

@Vasile-Caraus Maybe I’m missing the point, but it seems to me that an easy solution is by standard N++. One can select whatever piece of text one wants and then hit ctrl+j. This will join all lines in the selected text, creating a single (long) line.

Maybe I’m missing the point

The point you may be missing is that the OP probably has a lot of data to act upon, making doing it “by hand” impractical.
