Practical extracting and reporting

[ #7552 ]
I rarely use Perl for what Perl was originally (like in the 16:th century or something) built for; extracting and reporting. But today I did. And it was cool in all it's simplicity and usefulness.

Read through some files based on a filename regexp, identify the file, find some values, and summarize them in a table using MoinMoin (it's a Wiki) formatting. 20 minutes, including blocking some values, and providing aliases for some, and tweaking the table formatting. No longer than it would have taken me to do it manually, only:
  * It wasn't boring
  * It was correct, no chance to slip up
  * It can be done again at any time with updated files.

Oh, the joy of small scale automation :)

BTW, I also re-coded my canonical read-contents-of-a-file for the n:th time (I tend to do that in sooo many small scripts).

sub loadFile {
        my ($file) = @_;
        local $/;
        open(my $fh, $file) or return("");

File::Slurp isn't in the distribution, right? Well... it should.

  • You could use IO::File for your slurp
    use IO::File;

    my @lines = IO::File->new(shift)->getlines;
    Or something not entirely dissimilar to that.
