Subject: Windows based perl editor?
Message-Id: <1186108116.062326.177760@d55g2000hsg.googlegroups.com>
I have been using Edit (in a dos box) on Windows for editing perl for
the past 8 years or so, and though it is fine for me, I think it is
time to step up to a windows based editor. Can anyone recommend a good
windows based perl editor?
My wish list for what the editor would be able to do is:
1. Allow me to run the program I am editting in a dos box (using
active state perl)
2. Have multiple undos
3. Create multiple back up files as I save changes (a form of version
control so I can step back to a previous "version" if what I did
doesnt work right).
4. Syntax hilighting
5. Multiple programs open at the same time
6. Some form of project structure to allow me to group all the files
together
Most of these "wishes" come from the MS Visual C++ editor I used to
use before discovering perl.
Searching the internet I came across Perl Express (http://perl-
editor.perl-express.com/) but am leary of downloading programs I find
on the internet without knowing if they are safe.
I am not sure if this would influence your recommendtions but the
majority (99%) of the perl I write is used on web servers.
Any / all suggestions are appreciated.

Ultra-Edit32 is your best bet, it won't do most of what you wan't but
you can see closures. Plus the colors are nice if your on drugs.

I have been using GVim for a quite a while now (http://www.vim.org/)
I don't use it but there is also a Perl specific add-in.

I don't know about multiple backups but probably can be set up.

I am not sure what you mean by this.

Look up sessions.
For help with Vim, comp.editors is a good source.

If you use Eclipse you can consider the Eclipse Perl Integration
http://e-p-i-c.sourceforge.net/ .
I use this under Windows. I think that it has many/all of your
requirements. (I have personally not tried version control and
debugging as yet.)

Yes. GViM can open multiple files (or the same file) in multiple panes, above, below, to the right or left. And controls to rearrange them.

Mr. Corey: I am not sure why this needed to be posted three times.
In any case, of course, GVim can open multiple files at the same time.
However, the OP said "multiple programs". Given the fact that he has been
using EDIT all these years, I was not, and still am not, sure if he was
thinking of something else.

The only thing Robic0's module is good for is to serve as a bad example.
Go ahead and search Google Groups for it though - you'll find out what's
wrong with it quickly enough.

Here is some output from RxParse 1.1.
It easily identified the fact that you cannot specify
an "element-attribute" without a value for the attribute.
And that value must be in single or double quotes.
Most SAX Parsers give you a general and trivial error at a line/col.
RxParse goes the extra mile, in this case the "malformed element? '<select app>orig_gw'".
Its too easy to diagnose.
Btw, you should at least visit the W3C site to view the 1.1 form.

Validation only works on the contents of well formed XML.
"<xml><select app>orig_gw</select></xml>" is not valid and has a single element.
I think that you are not even aware of xml is quite evident.
To suggest to a poster with a problem, that the person who gave the only good
advice, is wrong about recommending a particular solution, is quite out of line.
I find your remarks insulting and not worth seeing you again!
Have a nice posting experience.
