NAME

Text::ASCIITable::EasyTable - create ASCII tables from hashes

SYNOPSIS

 use Text::ASCIITable::EasyTable;

 my $data = [
   { col1 => 'foo', col2 => 'bar' },
   { col1 => 'biz', col2 => 'buz' },
   { col1 => 'fuz', col2 => 'biz' },
 ];

 # easy
 my %index = ( ImageId => 'col1', Name => 'col2' );

 my $rows = [
   ImageId => sub { shift->{ $index{ shift() } } },
   Name    => sub { shift->{ $index{ shift() } } },
 ];
 
 print easy_table(
   data          => $data,
   rows          => $rows,
   table_options => { headerText => 'My Easy Table' },
 );

 # easier 
 print easy_table(
   data          => $data,
   columns       => [ sort keys %{ $data->[0] } ],
   table_options => { headerText => 'My Easy Table' },
 );
 
 # easiest 
 print easy_table( data => $data );

DESCRIPTION

Text::ASCIITable is one of my favorite modules when I am writing command line scripts that sometimes need to output data. It's so useful that I wanted to encourage myself to use it more often. Although, it is quite easy to use already I thought it could easier.

Easily create ASCII tables using Text::ASCIITable from arrays of hashes. Custom columns names can be sent to set the order of the data to be displayed in the table. You can also setup an array of subroutines that transform each element of the hash prior to insertion into the table. Rows can be ordered by one of the keys in the hash or you can provide a custom sort routine that will be called prior to rendering the table.

Exports one method easy_table.

METHODS AND SUBROUTINES

easy_table

rows

Array (not hash) of key/value pairs where the key is the name of one of the columns in the table and the value is either a subroutine reference that returns the value of for that column, an undefined value, or the name of a key in the hash that contains the value for that column.

 my $rows = [
   ID   => 'InstanceId',
   Name => sub { uc shift->{ImageName} },
   ];

• If the value provided for the column name key is a subroutine, it will be called with the hash for the current row being rendered and the column name.

• If the value is undefined then the value for that column will be the value of the hash member using the column name as the key.

• If the value is not a code reference, then that value is assumed to be the key to retrieve the value from the hash that will be inserted into table.

rows is an array, not a hash in order to preserve the order of the columns.

data

Array of hashes that contain the data for the table.

columns

Array of column names that represent both the keys that will be used to extract data from the hash for each row and the labels for each column.

sort_key

Key in the hash to use for sorting the array prior to rendering. If sort_key is a CODE reference, that method will be called prior to rendering.

table_options

Same options as those supported by Text::ASCIITable.

If neither rows or columns is provided, the keys are assumed to be the column names. In that case the order in which the columns appear will be non-determistic. If you want a specific order, provide the columns or rows parameters. If you just want to see some data and don't care about order, you can just send the data parameter and the method will more or less DWIM.
