I was looking at some convenient way to paste some strings I often use
personally. On EmacsWiki clipper.el was mentioned, but the link to it
was broken. Where is it on the Internet today?
Is there maybe a better way to do this? (I have no use for template in
my simple cases I believe.)

If you use a Debian-based distro, clipper is included in the
emacs-goodies package.

Have you tested using some global abbrevs? It's not "pasting" but it
types the text for you.
Abbrevs are really powerful!

let's say I need a function to find first printable character on the line
where the pointer is. This is what I'm trying to use:
(defun vb-first-printable ()
(interactive)
(let (limit-position)
(beginning-of-line)
(next-line 1)
(setq limit-position (point))
(previous-line 1)
(re-search-forward "\\S" limit-position 't)))
when I try executing this, I get the following error:
====================================================
Debugger entered--Lisp error: (invalid-regexp "Premature end of regular
expression")
re-search-forward("\\S" 3543 t)
(let (limit-position) (beginning-of-line) (next-line 1) (setq limit-position
(point)) (previous-line 1) (re-search-forward "\\S" limit-position (quote
t)))
vb-first-printable()
call-interactively(vb-first-printable)
===================================================
the same problem happens when I try re-search-forward from the command line:
if I enter "\S" as the pattern to search, I get "premature end of regular
expression" error, but if I enter "\\S" as the regular expression pattern,
the only thing it finds is this pattern (\\S) itself (as I try it on the same
file where the source code is).
What am I missing here?
TIA,
\vb

Commands that prompt you for a regexp allow you to enter it directly;
but when calling a Lisp function you have to specify the regexp as a
string, and in order to represent a backslash within a (double quote-
delimited) string literal you must double it: "This string has 1
backslash (here: \\) and 1 double quote (here: \")." And of course
the `\\' regexp matches the backslash character itself.
The manual states:
,----
| `\sC'
| matches any character whose syntax is C. Here C is a character
| that designates a particular syntax class: thus, `w' for word
| constituent, `-' or ` ' for whitespace, `.' for ordinary
| punctuation, etc. *Note Syntax::.
|
| `\SC'
| matches any character whose syntax is not C.
`----
So you must specify a syntax class `C', e.g. `w' for word constituent,
`-' or ` ' for whitespace, `.' for ordinary punctuation, etc.
But as there is no syntax class for printable or non-printable
characters, that seems like a dead end. But there is the [:print:]
character class that you can use in regular expressions.
And finally, all that limit-position/next-line/point/previous-line stuff
can be replaced by line-end-position:
(defun vb-first-printable ()
(interactive)
(beginning-of-line)
(re-search-forward "[[:print:]]" (line-end-position)))

Kevin,
thank you for your explanation. The [[:print:]] notation didn't quite work
either, but following your suggestion I tried \\S- and it worked.
(defun vb-first-printable ()
(interactive)
(beginning-of-line)
( if (re-search-forward "\\S-" (line-end-position) 't)
(backward-char)
)
)
Boy, nothing is what it seems with emacs :-)
cheers,
/vb

I wonder if you know about M-m?

This is a good question - no, I didn't! I suspected there was a command for
that but did not find it in a brief search.
But it was educational to figure out the emacs regexp search idiosyncrasy
anyways :-)

Ah, the [:foo:] character classes were introduced in Emacs 22.
