I *like* it!
A fellow Monk and I recently wrote a tool like this ourselves, but the in-memory
eval() isn't a capability of our implementation. Anyway, I have a slight
improvement to offer on your script. It concerns the mundane issue of where to save
a file on disk. Your default /tmp would be fine on a single-user workstation
but I thought about a multi-user system where security / privacy might be a greater
concern, and one would want to confine one's activities to one's ~USER/ ($HOME) dir.
This small patch makes sure that such a directory exists before allowing the script
to continue if writing to disk is going to be needed.
Here's the germane portion of what this change entails:
use File::Glob qw(:glob);
use File::Spec qw(file_name_is_absolute catfile);
# Configure this to an existing dir in your $HOME:
my $home_space = '';
# /end user config.
my ($HOME, $directory);
if ($opt_m or $opt_M or $opt_f or $opt_F) {
my $filename = $opt_f || $opt_F;
die "Don't pass an absolute path!\n" if
($filename and File::Spec->file_name_is_absolute($filename));
$HOME = (bsd_glob('~'.$ENV{LOGNAME} , GLOB_TILDE | GLOB_MARK))[0];
$HOME = ($HOME =~s%/\Z%%) ? $HOME : '';
# Be kind to some Win32 users, comment this out:
# die "No HOME found, no place to stash the code!\n" if not $HOME;
# Directory to save fetched code in:
$directory = $home_space ?
File::Spec->catfile($HOME, $home_space) : $HOME;
die "$directory does not exists.\n" if not -e $directory;
}
Fun.

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).
