Mazzy (File Manager Emulator)

As I remember, this code was written in 2006

What is it?

File Manager Emulator (FME) emulates the details of creating, removing, copying and moving files and directories. It also handles commands related to these file management tasks. FME shall be capable to read and execute a batch file with different kind of commands. After the batch file execution it shall generate and print out formatted directory structure or an error message if something went wrong to standard output. Note that program should do nothing with the real file structure on local hard drives and shall only emulate these activities.

Structure

Namespaceses and basic objects structure

Mazzy Cmd Parser Display Commands MakeDir ChangeDir RemoveDir MakeFile DelTree Del Copy Move MakeHardLink MakeDynLink FS Path FileSystem Object Dir File HLink DLink

Simple object structure in memory.

For example, if we have path like C:\mazzy\mazzy.cpp Mazzy will store in memory the next data structure:

Dir (Object) Name C: Type DIR Childs [0] » » » 0 « « «  Parent

Dir (Object) Name mazzy Type DIR Childs [0] » » » « « «  Parent

File (Object) Name mazzy.cpp Type FILE Childs empty « « «  Parent

Design patterns used

1. Singleton
2. Composite
3. Command
4. Facade

Using

1. Compile: just run g++ mazzy.cpp -o mazzy or run make
2. Run batch files: mazzy < batch.file
