NAME¶

Catmandu::Exporter::TSV - a tab-delimited TSV exporter

SYNOPSIS¶

    # From the command line
    # Provide a hint to the exporter which fields to export from the JSON
    # input. By default the TSV exporter will export the fields that are
    # found in the first JSON record.
    $ catmandu convert JSON to TSV --fields "id,title,year" < data.json
    # In a Perl script
    use Catmandu;
    my $exporter = Catmandu->exporter(
                'TSV',
                fix => 'myfix.txt',
                fields => "f1,f2,f3",
                header => 1);
    my $exporter = Catmandu->exporter(
                'TSV',
                fields => [qw(f1 f2 f3)]);
    $exporter->add_many($arrayref);
    $exporter->add_many($iterator);
    $exporter->add_many(sub { });
    $exporter->add($hashref);
    printf "exported %d items\n" , $exporter->count;

DESCRIPTION¶

This "Catmandu::Exporter" exports items as rows with tab-separated values (TSV). A header line with field names will be included if option "header" is set. See Catmandu::TabularExporter on how to configure the field mapping and column names. Newlines and tabulator values in field values are escaped as "\n", "\r", and "\t".

Hint: by default, the exporter will output all the fields that are found in the first record of the data input. This can be changed by setting the "fields" option of the exporter.

CONFIGURATION¶

file

Write output to a local file given by its path or file handle. Alternatively a scalar reference can be passed to write to a string and a code reference can be used to write to a callback function.

fh

Write the output to an IO::Handle. If not specified, Catmandu::Util::io is used to create the output handle from the "file" argument or by using STDOUT.

fix

An ARRAY of one or more fixes or file scripts to be applied to exported items.

encoding

Binmode of the output stream "fh". Set to "":utf8"" by default.

fields

See Catmandu::TabularExporter.

columns

See Catmandu::TabularExporter.

header

Include a header line with column names. Enabled by default.

sep_char

Column separator ("tab" by default)
