Name ^

App::Sqitch::ItemFormatter - Format events and changes for command output

Synopsis ^

  my $formatter = App::Sqitch::ItemFormatter->new(%params);
  say $formatter->format($format, $item);

Description ^

This class is used by commands to format items for output. For example, log uses it to format the events it finds. It uses String::Formatter to do the actual formatting, but configures it for all the various times of things typically displayed, such as change names, IDs, event types, etc. This keeps things relatively simple, as all one needs to pass to format() is a format and then a hash reference of values to be used in the format.

Interface ^

Constructor

new

  my $formatter = App::Sqitch::ItemFormatter->new(%params);

Constructs and returns a formatter object. The supported parameters are:

abbrev

Instead of showing the full 40-byte hexadecimal change ID, format as a partial prefix the specified number of characters long.

date_format

Format to use for timestamps. Defaults to iso. Allowed values:

iso
iso8601

ISO-8601 format.

rfc
rfc2822

RFC-2822 format.

full
long
medium
short

A format length to pass to the system locale's LC_TIME category.

raw

Raw format, which is strict ISO-8601 in the UTC time zone.

strftime:$string

An arbitrary strftime pattern. See "strftime Paterns" in DateTime for comprehensive documentation of supported patterns.

cldr:$pattern

An arbitrary cldr pattern. See "CLDR Paterns" in DateTime for comprehensive documentation of supported patterns.

color

Controls the use of ANSI color formatting. The value may be one of:

auto (the default)
always
never
formatter

A String::Formatter object. You probably don't want to pass one of these, as the default one understands all the values to that Sqitch is likely to want to format.

Instance Methods

format

  $formatter->format( $format, $item );

Formats an item as a string and returns it. The item will be formatted using the first argument. See "Formats" for the gory details.

The second argument is a hash reference defining the item to be formatted. These are simple key/value pairs, generally identifying attribute names and values. The supported keys are:

event

The type of event, which is one of:

deploy
revert
fail
project

The name of the project with which the change is associated.

change_id

The change ID.

change

The name of the change.

note

A brief description of the change.

tags

An array reference of the names of associated tags.

requires

An array reference of the names of any changes required by the change.

conflicts

An array reference of the names of any changes that conflict with the change.

committed_at

An App::Sqitch::DateTime object representing the date and time at which the event was logged.

committer_name

Name of the user who deployed the change.

committer_email

Email address of the user who deployed the change.

planned_at

An App::Sqitch::DateTime object representing the date and time at which the change was added to the plan.

planner_name

Name of the user who added the change to the plan.

planner_email

Email address of the user who added the change to the plan.

Formats ^

The format argument to format() specifies the item information to be included in the resulting string. It works a little bit like printf format and a little like Git log format. For example, this format:

  format:The committer of %h was %{name}c%vThe title was >>%s<<%v

Would show something like this:

  The committer of f26a3s was Tom Lane
  The title was >>We really need to get this right.<<

The placeholders are:
