My favorite tiny scripts for development and testing.
Script to make it easier to start developing your new Perl module under pressure of unit tests written in Test::More and the likes.
Suggested use is to have it sit on the other monitor, run all .t files around and around and be annoying about the fact that they fail. Then the rule of thumb goes without saying: "no green, no commit".
Binary dump. Reads STDIN, 4 bytes at a time and displays it in similar way as
hexdump(1)
does with -C
option (Canonical hex+ASCII display)
Example:
$ echo "Hello world" | ./bd.pl
00000000 01001000 01100101 01101100 01101100 |Hell|
00000004 01101111 00100000 01110111 01101111 |o wo|
00000008 01110010 01101100 01100100 00001010 |rld.|

Split URLs into components and arguments. Output is useful to see more easily what is or is not in the URL and/or compare URls using standard tools like diff.
$ dissect_url "proto://srv:port/a/query?par1=foo&par2=bar#joe&mary"
proto://srv:port
/a/query
?
par1=foo&
par2=bar
#
joe
Note that by removing all whitespace from the dissected URL you should get the original URL.
To enter multiple URLs, simply omit the argument; script will go into filter
mode, where you can enter URLs one per line. Quit this mode by entering EOF
(Ctrl+D
) or an empty line. From this mode, output will be separated like this:
$ dissect_url < two_urls
=== url 01 =============================================
url1
=== url 02 =============================================
url2
Make executable script for you and heat up vim. Accepts filename as parameter.

(yeah, hardcoded 0755
, no smartness here whatsoever)vim
or editor
for you.Script to measure how long does one second take. For those that know how long
one second takes, it can serve as a snippet for Perl &stamp()
.
Translate to and from Czech. Especially sweet if you need to concentrate on the work, i.e. avoid all the blinking flashing smiling Internets looks. This guy only tells you the woords.
se [options] word
Throw a word at it and by default, it will throw you back few Czech translations of it, one pair per line. Sweet. Also supports other languages (about 10 in total).
Most useful options are --lines
(default is 25), --long
, as shorthand
to --lines=50
, and --direction
, which supports direction keyword in form
"LNcz.cz" or "LNcz.LN", where LN is 2-letter code (not ISO) of the other
language.
Uses www.slovnik.cz, so an Internet connection and LWP::Simple are needed.
Has POD doc (se --man
or se --help
) worth looking at.
Trivial utility that prints a text file, clears the screen and pauses for 2s over and over.
Designed mainly for use with helper::dmup();
to enable you to see changes
in your dumped data structure continuously, but obviously you can use it for
any text file that will fit your screen.
For improved visual feedack, it will pre-pend the file contents with the file
path and an "animation". Display of the header can be controlled by options,
see --usage
.
Simple scripts to read YAML/Perl data structure from a file and dump it in the other format to STDIN. Uses YAML::Tiny for YAML jobs.
Prints overview of TCP connection details (IP addresses, ports, server user@host, time); 7 lines of plain text.
Collects GET requests with parameters msg, tag and i and logs them into single text file.
name=john;age=32;state=il
test01-012
.. test01-013
to
store the iteration number, you'll be better off with this parameter as
it won't break your ability to use tagsSend a 7-bit plain-text file via HTTP. One of these is sent:
random content of random length given by parameters min and max
EICAR test virus file
Chance to receive EICAR is given by parameter eicar (0-100).
Container module for some utility methods for Perl. Probably only dmup()
is interesting—it bears a nice quick and dirty way for dumping Perl
data.
APIs to make usage of htlog.cgi in Perl and Python scripts even easier
use htlogr;
my $logger = htlogr::new('http://192.168.1.1/cgi-bin/htlog.cgi');
# we don't need tag nor iteration number, but it can be useful
my $tag = "synopsis_test";
$logger->log("Commencing synopsis test", $tag);
my $data = {
foo => 1,
bar => "Hello world"
};
foreach my $i (1..1000) {
# log normal messages--with I!
$logger->log("next 10 done!", $tag, $i) unless ($num % 100);
# or a simple one-level data structures
$logger->data(
my_func_returning_hashref($data),
$tag,
$i
);
}
