search and replace

search and replace

[David Rasmussen]

I am trying with query replace to replace

\ncline[linewidth=0.3mm,offset=-1.5mm,arrows=->,nodesep=4mm]

with

\traverse

but it just replaces 0 occurrences. I don't understand why.

Do I have to do anything special? Is it because the string contains 
special characters or ... ?

No.  Most likely.  Did you try partial searches up to say the "," and/or
the "-"?  "-" (at the least) need to be escaped...

Hyphen have to be escaped?  Know of a situation where that-s
true?

Maybe it was a typo, and instead meant the square-brackets (for 
char-class)?

Thanks!

Sorry - I missed the first "\" and "[" - those mean something in regexps
so they need to be escaped as well...

I didn't think M-% (query and replace) worked on regexps. Is there a way 
to do search on replace on raw text, not regexps?

You were right in your thinking - it doesn't work on regexps. I tried
copying the

  \ncline[linewidth=0.3mm,offset=-1.5mm,arrows=->,nodesep=4mm]

into *scratch* and used M-% to query-replace it with \traverse. It
works fine here. Remember that if you place the cursor on top of the
above line, Emacs won't find it. You need to place the cursor before the
line for Emacs to find it.

Hmm. I had a file containing something like:

\ncline[linewidth=0.3mm,offset=-1.5mm,arrows=->,nodesep=4mm]{a}{b}
\ncline[linewidth=0.3mm,offset=-1.5mm,arrows=->,nodesep=4mm]{b}{c}
\ncline[linewidth=0.3mm,offset=-1.5mm,arrows=->,nodesep=4mm]{c}{d}
\ncline[linewidth=0.3mm,offset=-1.5mm,arrows=->,nodesep=4mm]{d}{e}
\ncline[linewidth=0.3mm,offset=-1.5mm,arrows=->,nodesep=4mm]{e}{f}
\ncline[linewidth=0.3mm,offset=-1.5mm,arrows=->,nodesep=4mm]{f}{g}

And I did M-% to replace 
\ncline[linewidth=0.3mm,offset=-1.5mm,arrows=->,nodesep=4mm]
with
\traverse

The cursor was before any of these line (and even if not, the search 
wraps around anyway, doesn't it?). It just said "0 occurences replaced".

I don't understand why... I had to use another editor to perform the 
replace :(

No, it never wraps around.

I tried those lines too, and it still works as expected. Someone
strange must have happened.

It doesn't wrap around by default. Putting the cursor on the line
above \ncline certainly works here. I am running Emacs out of CVS
from a month or two ago. Perhaps there was a bug in a released
version? I do consider the fact that you can't do the replace on the
line in question a bug, but otherwise it does seem to work.

My apologies :-)  The trouble with remapped keys is you remember what they
do but forgot what they are.  I use 'query replace regexp' in place of
'query replace'...

Search and replace

[tho643]

Here's an example of what I'm trying to do in my emacs console:

me@your-domain.com
you@my-domain.com
this@no-domain.com

Now after a search and replace this is what I want to get:

your-domain.com
my-domain.com
no-domain.com

I do not konw how to get rid of the 'me' 'you' 'this' and '@' in one
search and replace command.  I know how to change the @, but how would
be able to delete it, and everything else that happens to come before
it, on the same line.  I hope this makes sense to you.

Thanks

M-x replace-regexp RET .+@\(.*\) RET \1

But this macro do the same job:

C-a			;; move-beginning-of-line
C-SPC			;; set-mark-command
C-s			;; isearch-forward
@			;; self-insert-command
RET			;; newline
C-w			;; kill-region
C-n			;; next-line

and than C-x C-k r on region

:-)

Even simpler:

M-x replace-regexp RET .+@ RET RET
