Hi.

Looks like progress.

When I run into trouble with perl that I cannot seem to solve by looking in the books, I often search PerlMonks - The Monastery Gates -- they have an enormous body of snippets, articles, questions/answers, and discussions to address many issues.

If you are interested in pretty-printing/tidying your code on macOS, I see that perltidy is available via brew:

Code:

Results for program brew (key "b")
 ( brew writes to /usr/local )
==> Formulae
perltidy

 Results for program fink (key "f")
 ( fink writes to /sw )
Scanning package description files
Information about 306 packages read in 2 seconds.

 Results for program port (key "p")
 ( port writes to /opt/local )
Error: Port perltidy not found

So I'm using:

Code:

OS, ker|rel, machine: Apple/BSD, Darwin 18.7.0, x86_64
Distribution        : macOS 10.14.6 (18G84), Mojave
perltidy - ( local: /usr/local/bin/perltidy, v20190601 )

The graph looks better to me -- keep on perlin' ... cheers, drl

lwp-download

LWP-DOWNLOAD(1p)					User Contributed Perl Documentation					  LWP-DOWNLOAD(1p)

NAME

       lwp-download - Fetch large files from the web

SYNOPSIS

       lwp-download [-a] [-s] <url> [<local path>]

DESCRIPTION

       The lwp-download program will save the file at url to a local file.

       If local path is not specified, then the current directory is assumed.

       If local path is a directory, then the last segment of the path of the url is appended to form a local filename.  If the url path ends with
       slash the name "index" is used.	With the -s option pick up the last segment of the filename from server provided sources like the Content-
       Disposition header or any redirect URLs.  A file extension to match the server reported Content-Type might also be appended.  If a file
       with the produced filename already exists, then lwp-download will prompt before it overwrites and will fail if its standard input is not a
       terminal.  This form of invocation will also fail is no acceptable filename can be derived from the sources mentioned above.

       If local path is not a directory, then it is simply used as the path to save into.  If the file already exists it's overwritten.

       The lwp-download program is implemented using the libwww-perl library.  It is better suited to down load big files than the lwp-request
       program because it does not store the file in memory.  Another benefit is that it will keep you updated about its progress and that you
       don't have much options to worry about.

       Use the "-a" option to save the file in text (ascii) mode.  Might make a difference on dosish systems.

EXAMPLE

       Fetch the newest and greatest perl version:

	$ lwp-download http://www.perl.com/CPAN/src/latest.tar.gz
	Saving to 'latest.tar.gz'...
	11.4 MB received in 8 seconds (1.43 MB/sec)
