This is my first attempt to create a Perl script.

This script is to convert Markdown files to plain text ones, with some "common" typographic substitutions.

When I finish it, it is assumed to work as follows:

  1. Single-hyphen dashes are replaced with three hyphens: that is, foo - bar is replaced with foo---bar
  2. Markdown-style italic is replaced with Org Mode-style italic: that is, foo *bar* baz is replaced with foo /bar/ baz
  3. Blank lines are replaced with first-line indents, that is:
    ``` FROM THIS This is a 500-character line of text.

    This is another 500-character line of text. ```

    TO THIS This is a 500-character line of text. This is another 500- character line of text.

  4. Lines are hard-wrapped at 72 characters, and additionally:
  5. Any single-letter word, such as "a" or "I", if it happened to be at the end of a hard-wrapped line, unless it is the last word in a paragraph, is moved to the next hard-wrapped line, that is:
    FROM THIS He knows that I love bananas.

    TO THIS He knows that I love bananas.

And now the first draft. Please don't laugh too loudly 😀

```

!/usr/bin/perl


perl -pi -e 's/ - /---/g' $1 # foo - bar to foo---bar perl -pi -e 's/*///g' $1 # foo to /foo/ perl -pi -e 's/\n{2}/\n /g' $1 # blank lines to first-line indents ```

The first two lines work fine.

But I really don't understand why the third line doesn't replace blank lines with first-line indents.

Also, maybe someone can point me to an existing Perl or Awk script that does all of this.

This is not Perl specific, but in our new era of this Perl economy everyone should be thinking about side-hustles and income streams. Perl is perfect for creating SaaS and other services because for efficient practitioners it presents the most efficient way to prototype a lot of things via the web.

For example, shared hosting is dirt cheap and supports cgi-bin; VMs on the cloud are also dirt cheap and you probably don't need more than a $5 instance to POC something that will be good enough to test interest. Knowing more about pricing models is part of that. This is an interesting article about SaaS pricing models, and know more about that is certainly part of creating paid services. Enjoy.

Hi! Asking for a wisdom here...

We have a module that modifies signal handler $SIG{__DIE__} to log information and to die afterwards. Hundreds of scripts relied on this module which worked fine in perl 5.10.1.

Recently we had the opportunity to install several Perl versions but unfortunately a large number of scripts that used to work with Perl 5.10.1 now behave differently:

  • Failed in 5.14.4: /home/dev/perl-5.14.4/bin/perl -wc test.pl RECEIVED SIGNAL - S_IFFIFO is not a valid Fcntl macro at /home/dev/perl-5.14.4/lib/5.14.4/File/stat.pm line 41
  • Worked without changes in 5.26.3: /home/dev/perl-5.26.3/bin/perl -wc test.pl test.pl syntax OK
  • Worked without changes in 5.38.2: /home/dev/perl-5.38.2/bin/perl -wc test.pl test.pl syntax OK

Many of the scripts can only be updated to 5.14.4 due to the huge jumps between 5.10 and 3.58; But we are stuck on that failures.

Was there an internal Perl change in 5.14 which cause the failures but works on other recent versions without any update on the scripts?

Cheerio!

My environment is perl/5.18.2 on CentOs 7

I'm trying to use a SWIG generated module in perl, which has a c plus plus backend. The backend.cpp sets an environment variable, $MY_ENV_VAR =1

But when I try to access this in perl, using $ENV{MY_ENV_VAR} this is undef.

However doing something like print echo $MY_ENV_VAR works

So the variable is set in the process, but it's not reflected automatically since nothing updates the $ENV data structure.

I'm assuming it may work using some getEnv like mechanism, but is there a way to reset/ refresh the $ENV that it rebuilds itself from the current environment?

Im working on a script to test using a jump server to reach remote devices.

I'm able to connect to the jump server using Net::SSH::Expect, however, I'm not sure how to then ssh to a remote device (network element).

Is there a way to create that ssh to the remote device inside the jump server's connection?

First things first, I am a data engineer but have little experience in Perl. I've been able to make some easy updates to scripts in the past but this one is a bit tougher.

I have been asked to update a Perl cgi web app that someone wrote ages ago that is used to view and manipulate text files. Currently it is hosted on server (X) and manipulates the files on that same server. However, we have to have backups/mirrors of the data on a dev server and another prod sever (Y). I.e., if I push the button to move the file to a different folder, it should do that on all three servers instead of just X. I added code to do this, referencing the additional servers with their UNC names, but I just get an error "No such file or directory" (which is not true). Googling has suggested that there may be an issue with permissions, but I can bring up the Y and DEV servers from a windows file explorer using the same path so I don't think that is necessarily the issue.

Example: Here we are trying to copy the file with a letter appended a given number of times. It works fine on the X server, its when trying to make it also work on the Y and DEV servers I get an error.

our $DIR_X = "\\\\serverX\\folder\\subfolder" ; our $DIR_Y = "\\\\serverY\\folder\\subfolder"; our $DIR_DEV = "\\\\serverDEV\\folder\\subfolder"; . . . }elsif ($query->param('action') eq 'split' && $query->param('fileNum') ne "") { my $fileNum $query->param('fileNum'); my $fileX=$DIR_X . "\\" . $fileNum . ".txt"; my $fileY $DIR_Y . "\\" . $fileNum . ".txt"; my $fileDEV = $DIR_DEV . "\\" . $fileNum . ".txt"; my $splitNbr = $query->param('splitNbr'); my @letters1("a".. "z"); for (my $i = 0; $i < $splitNbr; $i++) { my $FileNew_X = $DIR_X . "\\" $fileNum. $letters[$i]=.txt"; my $FileNew_Y = $DIR_Y . "\\" $fileNum. $letters[$i]=.txt"; my $FileNew_DEV = $DIR_DEV . "\\" $fileNum. $letters[$i]=.txt"; copy($fileX, $FileNew_X) or die "WARNING: copy failed: $!\n"; ---->>>>>ERROR AT NEXT LINE copy($fileY, $FileNew_Y) or die "WARNING: copy failed: $!\n"; copy($fileDEV, $FileNew_DEV) or die "WARNING: copy failed: $!\n"; } 

Any thoughts?
