Test::Inline::IO::File - Local Filesystem IO Handler
Test::Inline 2.00 was conceived in an enterprise setting, and retains the flexibilty, power, and bulk that this created.
The intent with the FileHandler system is to allow Test::Inline to
be able to pull source data from anywhere, and write the resulting test
scripts to anywhere.
Until a more powerful pure-OO file-system module comes along in the form of the FSI project, this serves as a minimalist implementation of the functionality that Test::Inline needs in order to work.
An alternative FileHandler class need not subclass this one, merely
implement the same interface, taking whatever alternative arguments to
the new constructor that it wishes.
All methods in this class take unix-style paths, translating to the underlying filesystem if required.
The new constructor takes a root path on the local filesystem
and returns a new Test::Inline::IO::File object to that
location.
The exists_file method checks to see if a particular file currently
exists in the input handler.
Returns true if it exists, or false if not.
The exists_dir method checks to see if a particular directory currently
exists in the input handler.
Returns true if it exists, or false if not.
The read method reads in the entire contents of a single file,
returning it as a reference to a SCALAR. It also localises the
newlines as it does this, so files from different operating
systems should read as you expect.
Returns a SCALAR reference, or undef on error.
The write method writes a string to a file in one hit, creating
it and it's path if needed.
Assuming your input FileHandler is pointing at the root directory
of a lib path (meaning that My::Module will be located at My/Module.pm
within it) the class_file method will take a class name, and check to see
if the file for that class exists in the FileHandler.
Returns a reference to an ARRAY containing the filename if it exists,
or undef on error.
The find method takes as argument a directory root class, and then scans within
the input FileHandler to find all files contained in that class or any
other classes under it's namespace.
Returns a reference to an ARRAY containing all the files within the class,
or undef on error.
- Convert to using FSI::FileSystem objects, once they exist
