file: $CPAN/authors/id/H/HM/HMBRAND/Text-CSV_XS-0.40.tgz size: 85057 bytes md5: cb8b2af20925b832159f34eed9793666 2008-04-07 0.40 - H.Merijn Brand * Implemented getline_hr () and column_names () RT 34474 (suggestions accepted from Mark Stosberg) * Corrected misspelled variable names in XS * Functions are now =head2 type doc entries (Mark Stosberg) * Make SetDiag() available to the perl level, so errors can be centralized and consistent * Integrate the non-XS errors into XS * Add t/75_hashref.t * Testcase for error 2023 (Michael P Randall) * Completely refactored the XS part of parse/getline, which is now up to 6% faster. YMMV * Completed bind_columns. On straight fetches now up to three times as fast as normal fetches (both using getline ()) getline_hr The "getline_hr ()" and "column_names ()" methods work together + to allow you to have rows returned as hashrefs. You must call "column_names ()" first to declare your column names. $csv->column_names (qw( code name price description )); $hr = $csv->getline_hr ($io); print "Price for $hr->{name} is $hr->{price} EUR\n"; "getline_hr ()" will croak if called before "column_names ()". column_names Set the keys that will be used in the "getline_hr ()" calls. If + no keys (column names) are passed, it'll return the current setting. "column_names ()" accepts a list of scalars (the column names) +or a single array_ref, so you can pass "getline ()" $csv->column_names ($csv->getline ($io)); "column_names ()" croaks on invalid arguments. bind_columns Takes a list of references to scalars (max 255) to store the fi +elds fetched "by getline_hr ()" in. When you don't pass enough refer +ences to store the fetched fields in, "getline ()" will fail. If you pas +s more than there are fields to return, the remaining references are l +eft untouched. $csv->bind_columns (\$code, \$name, \$price, \$description); while ($csv->getline ()) { print "The price of a $name is \x{20ac} $price\n"; }

Enjoy, Have FUN! H.Merijn

[Cosmic37]: if ( $line =~ /$mydt/ ) { print $line; }
[Cosmic37]: I try to match successive date times stored in variable $mydt
[Cosmic37]: I guess it is searching for the string "$mydt"
[Corion]: Indeed cool, erix ;)
[Cosmic37]: rather than the value of $mydt which is a date time strong such as 2016-01-01 12:30:56
[Corion]: Cosmic37: No, but maybe $mydt doesn't contain what you think it does, or it contains characters that are special in a regular expression? Try if( $line =~ /\Q$mydt\E/) { ... for a literal match
[Cosmic37]: I mean string grrr
[Corion]: Maybe add an else branch in which you print what the values of $line and $mydt are?
[Cosmic37]: ah thank you I will try
[Cosmic37]: you are right $mydt did not contain what I expected... :-D I will now think :-D
