NAME

Form - A Raku implementation of Perl-style string formatting

SYNOPSIS

use Form;

my @items  = ('Widget A', 'Widget B');
my @prices = (9.99, 24.50);

print form
    'Item                   Price',
    '----------------------------',
    '{[[[[[[[[[[[[[[[[[[[} {]].[}',
    @items,                @prices;

# Item                   Price
# ----------------------------
# Widget A                9.99
# Widget B               24.50

DESCRIPTION

An implementation of Perl's Form module, as described by Exegesis 7 and Damian Conway's Perl6::Form module.

Full documentation: docs/Form.md

NUMERIC FIELDS

Numeric fields use ] (block) or > (line) for the integer part, an arbitrary decimal marker character, and [ (block) or < (line) for the fractional part, all enclosed in { }.

The closing brace } always contributes one position to the fractional width, and the opening brace { always contributes one position to the integer width. This means:

• {]].} — 1 decimal place (no [ chars; } alone provides fracs-width=1)

• {]].[} — 2 decimal places (one [ plus })

• {]].[[} — 3 decimal places (two [ plus })

The minimum is 1 decimal place. A bare trailing decimal like 0. is not supported by design — {]].} gives 0.0, not 0..

Numbers are rounded to the specified number of decimal places and zero-padded (e.g. 1.5 in a 2-decimal field renders as 1.50).

TODO

• Currencies
• Complex numbers
• Everything else
