NAME

FFI::Build::File::Base - Base class for File::Build files

VERSION

version 1.56

SYNOPSIS

Create your own file class

 package FFI::Build::File::Foo;
 use parent qw( FFI::Build::File::Base );
 use constant default_suffix => '.foo';
 use constant default_encoding => ':utf8';

Use it:

 # use an existing file in the filesystem
 my $file = FFI::Build::File::Foo->new('src/myfile.foo');
 
 # generate a temp file with provided content
 # file will be deletd when $file falls out of scope.
 my $file = FFI::Build::File::Foo->new(\'content for a temp foo');

DESCRIPTION

This class is the base class for other FFI::Build::File classes.

CONSTRUCTOR

new

 my $file = FFI::Build::File::Base->new(\$content, %options);
 my $file = FFI::Build::File::Base->new($filename, %options);

Create a new instance of the file class. You may provide either the content of the file as a scalar reference, or the path to an existing filename. Options:

base: The base name for any temporary file "ffi_build_" by default.
build: The FFI::Build instance to use.
dir: The directory to store any temporary file.
platform: The FFI::Build::Platform instance to use.

METHODS

default_suffix

 my $suffix = $file->default_suffix;

MUST be overridden in the subclass. This is the standard extension for the file type. ".c" for a C file, ".o" or ".obj" for an object file depending on platform. etc.

default_encoding

 my $encoding = $file->default_encoding;

MUST be overridden in the subclass. This is the passed to "binmode" when the file is opened for reading or writing.

accept_suffix

 my @suffix_list = $file->accept_suffix;

Returns a list of regexes that recognize the file type.

path

 my $path = $file->path;

The full or relative path to the file.

basename

 my $basename = $file->basename;

The base filename part of the path.

dirname

 my $dir = $file->dirname;

The directory part of the path.

is_temp

 my $bool = $file->is_temp;

Returns true if the file is temporary, that is, it will be deleted when the file object falls out of scope. You can call "keep", to keep the file.

platform

 my $platform = $file->platform;

The FFI::Build::Platform instance used for this file object.

build

 my $build = $file->build;

The FFI::Build instance used for this file object, if any.

native

 my $path = $file->native;

Returns the operating system native version of the filename path. On Windows, this means that forward slash "\" is used instead of backslash "/".

slurp

 my $content = $file->slurp;

Returns the content of the file.

keep

 $file->keep;

Turns off the temporary flag on the file object, meaning it will not automatically be deleted when the file object is deallocated or falls out of scope.

build_item

 $file->build_item;

Builds the file into its natural output type, usually an object file. It returns a new file instance, or if the file is an object file then it returns empty list.

build_all

 $file->build_all;

If implemented the file in question can directly create a shared or dynamic library without needing a link step. This is useful for languages that have their own build systems.

needs_rebuild

 my $bool = $file->needs_rebuild
