If you must use a module for this, may I suggest Path::Tiny or File::Slurper?

While those modules are nice, I personally find it a bit difficult to keep track of all of the different modules' opinions on how to best slurp files. And considering that slurping a file takes at most two lines of pure Perl code and I remain in full control over layers etc., I no longer see the need to load a module just for that. The following only requires knowing some of the details of layers, such as knowing the effect of ${^OPEN}, using :encoding(UTF-8) instead of :utf8, and that UTF-16 files on Windows require the layers :raw:encoding(UTF-16):crlf (the latter two being documented in PerlIO and "open" Best Practices).

my $all = do { open my $fh, '<', $filename or die "$filename: $!"; local $/; <$fh> }; my @lines = do { open my $fh, '<', $filename or die "$filename: $!"; <$fh> }; chomp @lines;

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
