NAME Text::ECSV - Extended CSV manipulation routines SYNOPSIS use Text::ECSV; $ecsv = Text::ECSV->new (); # create a new object $line = 'id=3,name=Text::ECSV,shot_desc=Extended CSV manipulation routines'; $status = $ecsv->parse ($line); # parse a CSV string into fields # and name value pairs %columns = $ecsv->fields_hash (); # get the parsed field hash $column = $ecsv->field_named('id'); # get field value for given name $ecsv->combine('b' => 2, 'a' => 1, 'c' => 3, ); # ok($ecsv->string eq 'b=2,a=1,c=3'); DESCRIPTION " use base 'Text::CSV_XS'; " => see Text::CSV_XS. Roland Giersig had a presentation at YAPC 2007 called 'Techniques for Remote System-Monitoring'. He was explaining his search after a good logging format or how to store continuous flow of data in a most usable form. XML? YAML? CSV? XML is nice but for a machines not for humans, YAML is nice for both but it's hard to grep. CSV is readable and grep-able but not too flexible. So what is the conclusion? ECSV is like a CSV but in each comma separated field the name of the column is set. This gives a flexibility to skip, reorder, add the fields. All the information is stored per line so it's easy to grep. Also it's easy to compare two records by md5-ing the lines or doing string eq. PROPERTIES fields_hash Holds hash reference to the resulting hash constructed by "parse()". dup_keys_strategy If set and a dupplicate key names occure in a parsed line, this strategy is called with "->($name, $old_value, $value)". Can be used for duplicate keys to join values to one string, or push them to an array or to treat them how ever is desired. By default values overwrite each other. METHODS field_named($name) Return field with $name. parse() In aditional to the "SUPER::parse()" functionality it decodes name value pairs to fill in "fields_hash". combine($key => $value, ...) The function joins all $key.'='.$value and then calls "SUPER::combine" constructing a CSV from the arguments, returning success or failure.
