Editing Control Characters, Linefeeds, Etc.

Editing Control Characters, Linefeeds, Etc.

[Karl Dahlke]

I don't know precisely what you want to do,
but I guarantee, edbrowse can do it.
You can edit an executable file,
find the string "hello world",
change the w to a j,
write the file, and run it, and get the output:

hello jorld

To undos a file, do this.

,s/\r$//

CR in the middle of a line should probably become a true line break.

,s/\r/\n/g

Change all collections of tabs and spaces to a single space.
Remember, whitespace doesn't mean anything in html, so may as well simplify it.

,s/[ \t]+/ /g

I have an edbrowse script that does a fair job of unwording a file,
so you can read the text in whatever.doc.
For more info, send questions to eklhad@comcast.net.

Editing Control Characters, Linefeeds, Etc.

[John J. Boyer]

Hello,

This also pertains tho the websirte I am maintaining, which is for 
Wisconsin Braille, Inc. The original website was created using Frontpage. 
I've been trying out Tidy on it and may use Edbrowse also. Some of the 
material that goes on it is originally from Word files. This material has 
a lot of extra linefeeds and a lot of tabs when it is converted to text. 
Is there an editor which can do a find and replace on these characters?

Thanks,
John

John,

Emacs can do this, though it's taken me six months to find out how and I
may not be doing it the best way (part of the reason I'm responding).

To enter a control character, precede it with a C-Q. To replace all
occurrences of a string after Point, use the replace-string function.

For example: Recently I had to repair a Web Braille file (Captains 
Courageous) with faulty end-of-page sequences that my bb.sh script 
couldn't handle. The key sequence was as follows:

C-M-< (top-of-file)
M-xreplace-s<tab> (resulted in replace-string)
<Enter>
^q^m^q^l
<enter>
^q^m^q^j^q^l
<enter>

All done.

I've been using emacs for the past 6 months solid and am still by no 
means fond of its interface, but it seems to be able to do lots of 
stuff if you have a few lifetimes to find out how.

On a very distantly-related note, how can people not on Debian handle 
Debian packages? I tried once getting edbrowse but got depressed 
before figuring out how to deal with .deb files. No fair cheating by 
telling me I don't need the Debian distribution; I want to know about 
.deb files whether or not it's necessary in this case. <Grin>

Thanks and hope this helps,

Lee

I realized as I got up this morning that top-of-file is M-<, not C-M-<. 
This is corrected in the version below:

sed can handle control characters if you have a version that's fancy
enough.  I'm pretty certain doing these kinds of conversions is listed in
the sed.faq file.  There's tr that can be used too.  You can join
sed-users and that's a yahoogroups.com mailing list if you run into any
problems.
