[Pdx-pm] any one know of an editor that allows for embeded perl?

[Ben Prew]

Rather then just blather on about the theoretical uses of some theoretical
text editor, there's an article on how to customize emacs in perl:

http://www.perl.com/pub/a/2005/03/31/lightning2.html

Also, I would recommend looking up narrowing and widening in the emacs elisp
tutorial:

http://www.gnu.org/software/emacs/emacs-lisp-intro/html_node/Narrowing---Widening.html

And, the elisp reference has information on "the region", which is the text
between the point and the mark... or, the currently selected text:

http://www.gnu.org/software/emacs/elisp-manual/html_chapter/elisp_31.html#SEC492

Ultimately, just about anything you can do in Perl can probably be done
better in elisp... except for expressing a regular expression, its very
similar to Python or Java :(. See Ahh, the Regexes for what I'm talking
about:

http://obsidianrook.com/devnotes/whinery/elisp-regexps.html

And, along that same vein, if you're thinking about learning elisp, here's a
translation of common perl idioms to elisp:

http://obsidianrook.com/devnotes/elisp-for-perl-programmers.html

I don't know how well they map to good "lisp-style", but they appear to be
pretty good.

Finally, I must say that even though I prefer emacs, Vim can be compiled
with Perl support built-in, so you can use it directly in your vim scripts,
and don't have to shell out to Perl.

Unfortunately, I don't have much experience with that, so you'll have to ask
someone else about it :).
