unwrapping lines

unwrapping lines

[Girish Kulkarni]

Hello,

I'm stuck with a curious problem and wonder if I can solve it in
Emacs. I have a data file produced by Mathematica that lists four
quantities. High precision means these numbers tend to be long so
Mathematica often has to truncate lines. It does so by putting in a
backslash and continuing on the next line. For example:

0.17000000000000004 0.10500954682364379 0.20481153067700028 0.309821\
0775006441
0.18000000000000005 0.12459404398470066 0.22952096247531506 0.354115\
0064600157
0.19000000000000006 0.14646262095984275 0.25562017297341694 0.402082\
7939332597

I need to use these data in a Fortran 77 program. But Fortran has
problems reading numbers in that format. In Emacs I can remove that
backslash easily but that doesn't solve my problem. (Fortran then
treats the continued digits as a fifth quantity. This "fifth quantity"
is sometimes present and sometimes absent.)

Is there any way in which I can "unwrap" the lines so that all four
quantities appear in the same line? For example, I want the above to
look like:

0.17000000000000004 0.10500954682364379 0.20481153067700028
0.3098210775006441
0.18000000000000005 0.12459404398470066 0.22952096247531506
0.3541150064600157
0.19000000000000006 0.14646262095984275 0.25562017297341694
0.4020827939332597

I've tried using M-x replace-string with C-q C-d C-q C-d and C-d C-d
to replace "\" with two DELETE characters. Didn't work. Could somebody
help?

Girish

You may try:
M-x query-replace-regexp <ret> \\C-q C-j <ret><ret>

Have you tried this:

"M-x replace-string" "\C-o" ""

(without all the quotes)
to replace '\' followed by "new-line" with an empty string ("").


--livin.stephen


 From help on "C-o"
C-o runs the command open-line
   which is an interactive compiled Lisp function in `simple.el'.
It is bound to C-o, <insertline>.
(open-line n)

Insert a newline and leave point before it.
If there is a fill prefix and/or a `left-margin', insert them
on the new line if the line would have been blank.
With arg n, insert n newlines.

Thank you so much! That worked.
