Hi monks,
I've recently started into perl again and find that a lot of what I "knew" is no longer valid. It would seem that File::Slurp is outmoded. If I'm going to replace it with Path::Tiny, maybe I should do likewise with Path::Class, as suggested at this link by Path::Tiny's author. path class versus path tiny
I'm using Path::Tiny for a pet project just to get my feet wet, and I think I'm using it correctly, but I'm not sure why I'm being warned about wide characters. If I use utf8; and $path1->lines_utf8;, am I not projecting my intent? Where I'm really stumbling is with the logic of how to format this cleanly.
What I want is for the one-word titles to be centered. There are 71 characters in my lines. Vertical whitespace is to be preserved, that is, blank lines remain blank lines. Then I want the newlines removed if there is text on the next line. Such a look-ahead regex is well beyond my abilities, so I am asking for help. What I want in the end is for paragraphs to look like paragraphs with a 5-space indentation. I'm also doing some word substitution to make these promises more ecumenical for the less-believing types, who will bristle at the G-word. Here is the script:
#!/usr/bin/perl -w use strict; use 5.010; use Path::Tiny; use utf8; # creating Path::Tiny objects my $dir = path("/home/bob"); my $name = "1.promises.txt"; my $new_name = path($dir,"1.revised.txt"); my $path1 = path($dir, $name); # list say $path1; my $path2 = path("."); say $path2; # cwd my $path3 = path("~user/file.txt"); # tilde processing say $path3; #say "lines are @lines"; my @lines = $path1->lines_utf8; foreach my $i (0 .. $#lines) { say "i is $i"; say "$lines[$i]"; $lines[$i] =~ s/God/an arbitrary higher power/; $lines[$i]=~ s/Бог/боль
 +96;ая сила/; } $new_name->spew_utf8( @lines ); __END__
I am getting partial results in that I have output with the substitutions. Here is the source text, similar to many such texts I might pull out of the pdf's in which they originate:
Oбещания
Если эта фаза нашего развития болезненна для нас, мы
будем удивлены, когда половина пути окажется позади. Мы
познáем новую свободу и новое счастье. Мы не будем сожалеть
о нашем прошлом и вместе с тем не захотим полностью
забывать о нем. Мы узнаем, что такое чистота, ясность, покой.
Как бы низко мы ни пали в прошлом, мы поймем, что наш опыт
может быть полезен другим. Исчезнут ощущения ненужности и
жалости к себе. Мы потеряем интерес к вещам, которые
подогревают наше самолюбие, и в нас усилится интерес к
другим людям. Мы освободимся от эгоизма. Изменится наше
мировоззрение, исчезнут страх перед людьми и неуверенность
в экономическом благополучии. Мы интуитивно будем знать, как
вести себя в ситуациях, которые раньше нас озадачивали. Мы
поймем, что Бог делает для нас то, что мы не смогли сами
сделать для себя.
Не слишком ли это звучит многообещающе? Нет. Все это
произошло со многими из нас, с одними раньше, с другими
позже. Все это становится явью, если приложить усилия.
Promises
If we are painstaking about this phase of our development, we will be amazed
before half through! We are going to know a new freedom and happiness. We
will not regret the past nor wish to shut the door on it. We will comprehend the
word serenity and know peace. No matter how far down the scale we have
gone, we will see how our experience can benefit others. That feeling of use-
lessness and self-pity will disappear. We will lose interest in selfish things and
gain interest in our fellows. Self-seeking will slip away. Our whole attitude
and outlook upon life will change. Fear of people and of economic insecurity
will leave us. We will intuitively know how to handle situations which used to
baffle us. We will suddenly realize that God is doing for us what we could not
do for ourselves.
Are these extravagant promises? We think not. They are being fulfilled among
us—sometimes quickly, sometimes slowly. They will always materialize if we
work for them.

It would seem that I only have bad choices for displaying this material as the p tags destroy the whitespace and the c tags make the cyrillic unreadable. Thank you for your comment.
Update: attempting to use pre tags.
