NAME

App::Kit::Obj::FS - file system utility object

VERSION

This document describes App::Kit::Obj::FS version 0.1

SYNOPSIS

my $fs = App::Kit::Obj::FS->new();
my @guts = $fs->read_file(…);

DESCRIPTION

file system utility object

INTERFACE

new()

Returns the object.

Takes one required attribute: _app. It should be an App::Kit object for it to use internally.

Has 3 optional attributes:

spec

Lazy loads File::Spec and returns the class accessor for File::Spec methods. Setting this via new() is probably not a good idea.

my $dir = $fs->spec->catdir(…);

bindir

The applications main directory. Defaults to script’s directory or the current working directory.

Lazy loads FindBin and Cwd.

inc

An array ref of paths for file_lookup() to use. Defaults to [].

cwd()

Lazy wrapper of Cwd’s cwd().

file_lookup()

In scalar context returns the first path that exists for the given arguments.

In array context returns all possible paths for the given arguments without any existence check.

The final argument can be a config hashref with the inc key whose value is an array of paths.

The arguments are the pieces of the path you are interested in that get put together in a portable way.

my $conf = $fs->file_lookup('data', 'foo.json'); # e.g. …/my_app_base/.appkit.d/data/foo.json

The path is looked for in this order:

    1. the 'inc' paths in the given argument if any

    2. a directory in the object’s base path called .$prefix.d (where $prefix is the _app attributes’s ->str->prefix).

    3. the objects’s inc attribute

mkpath()

Lazy wrapper of File::Path::Tiny’s mk().

rmpath()

Lazy wrapper of File::Path::Tiny’s rm().

empty_dir()

Lazy wrapper of File::Path::Tiny’s empty_dir().

mk_parent()

Lazy wrapper of File::Path::Tiny’s mk_parent().

tmpfile()

Lazy wrapper of File::Temp’s tmpfile().

tmpdir()

Lazy wrapper of File::Temp’s tmpdir().

read_dir()

Lazy wrapper of File::Slurp’s read_dir().

read_file()

Lazy wrapper of File::Slurp’s read_file().

write_file()

Lazy wrapper of File::Slurp’s write_file().

json_read()

Lazy wrapper to consistently load a JSON file to a data structure.

my $data = $fs->read_json($file);

json_write()

Lazy wrapper to consistently write a data structure as a JSON file.

$fs->write_json($file, $data);

yaml_read()

Lazy wrapper to consistently load a YAML file to a data structure.

my $data = $fs->read_yaml($file);

yaml_write()

Lazy wrapper to consistently write a data structure as a YAML file.

$fs->write_yaml($file, $data);

get_iterator()

Lazy wrapper of Path::Iter’s get_iterator().

DIAGNOSTICS

'inc' must be an array ref

The value given for 'inc' was not an array ref.

CONFIGURATION AND ENVIRONMENT

Requires no configuration files or environment variables.

DEPENDENCIES

Moo for the object.

Lazy loaded as needed:

Cwd File::Path::Tiny File::Temp File::Slurp Path::Iter File::Spec FindBinCwd

INCOMPATIBILITIES

None reported.
