  Sorry. What I said was, "it seems a bit disingenuous to claim the autoboxed thing looks better than the alternative when you're not being honest about the alternative." What I meant was that given A: $string->split(" ")->reverse->join(" ")->say; B: say...
• Commented on Putting the ideas together, a hands on tutorial of modern Perl
  I agree with Mithaldu. I don't think adding a ton of parentheses adds clarity at all; it just adds a ton of parentheses. His version isn't just shorter, it's easier to both read and write. It seems a bit disingenuous...

  Neat! I did Nicomachus. I moved the "yes or no" logic into a subroutine and re-used it for the "try another". Otherwise, I guess we'd have to hit C-c to exit. #!/usr/bin/env perl # http://www.atariarchives.org/basicgames/showpage.php?page=117 use v5.12; use warnings; use...

• Posted I ♥ perlbrew to oylenshpeegul

  I love perlbrew! I like to keep the version of Perl that I normally use as up-to-date as possible, but it's nice to keep other versions around for compatibility. Just now, I needed to know when readline got fixed. With perlbrew, it was…

  I have been using Emacs for decades. I am totally happy with it (indeed, it keeps getting better and better!) and am not looking for another editor. Nonetheless I like to keep abreast of things, so when new tools become available, I like to check them out.

  For a while now, I have been hear…

• Aristotle commented on Q: When not to use Regexp? A: HTML parsing

  Usually you do not care about the structure of the whole HTML page but only the part you are interested in. The simplest way to identify that part is to match it with regexps, not by walking down a syntax tree.

  I don’t know what you are trying to do but last I tried, I found it far easier to locate a tag on an HTML page with a CSS selector than to laboriously match out the text with a pattern (not to mention having to manually handle charsets, unescaping etc. in that case). Even XPath is still a lot easier.

  Are you using a DOM and manually walking it with …

• Ed Avis commented on Q: When not to use Regexp? A: HTML parsing

  Yes, I have sometimes found it easier to use HTML::TableExtract or other modules which truly parse the HTML and walk over its structure. It depends on how well-structured the page is and what you are trying to extract. A CSS selector is a nice declarative approach, and as long as you are matching based on particular attributes rather than 'the third row in the fourth table', you will be fairly robust against minor layout changes.

  That said, a regexp approach can be declarative too. Because you can start by taking an example of the HTML you want to match and adding placeholders, it…

  Yes, that is what the link to “the cthulhu way” points to.

• Aristotle commented on Q: When not to use Regexp? A: HTML parsing

  Because you can start by taking an example of the HTML you want to match and adding placeholders, it is immediately clear what HTML structure is matched - as long as you keep your regexp nicely formatted and commented using /x.

  No amount of /x will make regexps look less messy than a CSS selector. Aside from that, the regexp will break not only when the layout breaks, but for even the most minor variation, such as the quotes around an attribute changing from double to single, or being removed altogether; the order of attributes changing; a comment being…
