We can do MAGIC now!

Dumping the content of a database ($dbh) table ($tbl) to CSV:

my $csv = Text::CSV_XS->new ({ binary => 1, eol => $/ });
open my $fh, ">", "$tbl.csv" or die "$tbl.csv: $!";
my $sth = $dbh->prepare ("select * from $tbl");
$sth->execute;
$csv->print ($fh, $sth->{NAME_lc});
while (my $row = $sth->fetch) {
$csv->print ($fh, $row);
}
close $fh;

2008-04-16 0.42 - H.Merijn Brand

* Generate META.yml myself. I won't use Build.PL
* Array-refs now accept scalars with magic:
$csv->print (*STDOUT, $sth->{NAME_lc});
* More/better examples
* Added t/76_magic.t

2008-04-11 0.41 - H.Merijn Brand

* error_diag () subclassable
* typo in bind_columns () docs
* examples/csv2xls now uses getline ()
* better test for getline in t/75_hashref.t (makamata)
* document return value of getline () with bind_columns ()
* add perl version prereq to META.yml

I'm just curious - why won't you use Build.PL? Just wondering in case it
may affect any time I might want to use it.

1. Because MakeMaker is good enough for me.
2. Because MakeMaker is clear enough for me (Build hides too much)
3. Build.PL neither does support what I want
4. Build requires me to use lib/, even if I just have a single .pm
5. I love the mantra
# perl Makefile.PL
# make test
# make install UNINST=1

Use whatever fits your needs best

of course, but do you want to?

Of course. But these man pages are to explain Text::CSV_XS' usage, not
generic
best practices. If I make the examples in the man strict and consice, I
would
have to include

use strict;
use warnings;

use Text::CSV_XS;

before every example. That will just hide the intent of the examples.

Yet:
open my $fh, ">", "$tbl.csv" or die "$tbl.csv: $!";

^^

YMMV but I would either do it where needed, or not at all. Examples like
yours (IMO) only propagate bad practices. If you want to keep your example
small, you could just put ... after each or.

I mean, why use cruft like:

open my $fh, ">", "$tbl.csv" or die "$tbl.csv: $!";

Added for the next release.

You'll understand that I don't agree here :) Not at all.

IMO: either use *proper* error handling everywhere in an example, or make
clear that it's missing.
