I have really come to enjoy the ideas and syntax offered by the
P5EE Style Guide.
In the guide, they offer this for plural vs singular variable naming conventions:
---
Arrays and hashes should be plural nouns, whether as
regular arrays and hashes or array and hash references. Do
not name references with ``ref'' or the data type in the
name.
@stories = (1, 2, 3); # right
$comment_ref = [4, 5, 6]; # wrong
$comments = [4, 5, 6]; # right
$comment = $comments->[0]; # right
---
By consistantly using a system like this throughout your programs, there won't have to be question about whether a scalar contains something like a string, or if it's a reference to an array or hash. As the guide suggests, references would be named in a plural fashion.
FWIW, I'm now using (or at least attempting to) this guide for all of my programming habits :-) Have fun,
-Eric

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
