NAME
Config::TOML - TOML file parser and writer
DESCRIPTION
Config::TOML exports two subroutines: from-toml and to-toml.
SYNOPSIS
TOML to Raku:
use Config::TOML;
# parse toml from string
my $toml = Q:to/EOF/;
[server]
host = "192.168.1.1"
ports = [ 8001, 8002, 8003 ]
EOF
my %toml = from-toml($toml);
# parse toml from file
my $file = 'config.toml';
my %toml = from-toml(:$file);
Raku to TOML:
use Config::TOML;
my %h = :a<alpha>, :b<bravo>, :c<charlie>;
to-toml(%h);
ADVANCED USAGE
Specifying a custom local offset for TOML date values
TOML date values can take three different forms:
RFC 3339 timestamps (YYYY-MM-ddThh:mm:ss.ffff+zz)
RFC 3339 timestamps with the local offset omitted (YYYY-MM-ddThh:mm:ss.ffff)
Standard calendar dates (YYYY-MM-dd)
Config::TOML builds Raku Dates from standard calendar dates.
By default, Config::TOML builds Raku DateTimes from TOML datetime values that do not include a local offset using the host machine's local offset. To override the default behavior of using the host machine's local offset for date values where the offset is omitted, pass the date-local-offset named argument (with an integer value) to from-toml:
my $cfg = slurp 'config.toml';
# assume UTC when local offset unspecified in TOML dates
my %toml = from-toml($cfg, :date-local-offset(0));
To calculate a target timezone's local offset for the date-local-offset named argument value, multiply its UTC offset hours by 60, add to this its UTC offset minutes, and multiply the result by 60.
| Timezone | UTC Offset | Calculation | |
|---|
| Africa/Johannesburg | UTC+02:00 | ((2 * 60) | 0) * 60 = 7200 |
| America/Los_Angeles | UTC-07:00 | ((-7 * 60) | 0) * 60 = -25200 |
| Asia/Seoul | UTC+09:00 | ((9 * 60) | 0) * 60 = 32400 |
| Australia/Sydney | UTC+10:00 | ((10 * 60) | 0) * 60 = 36000 |
| Europe/Berlin | UTC+01:00 | ((1 * 60) | 0) * 60 = 3600 |
| UTC | UTC±00:00 | ((0 * 60) | 0) * 60 = 0 |
To more easily ascertain your host machine's local offset, open a Raku repl and print the value of $*TZ.
