FOR USERS THAT ONLY WANT THE TREE AND NOT THE HELPER CODE

Switch to the no_helpers branch, that branch has been made for users that want just the tree, because they wanna use it for something else. I get where those people are coming from, because initially even I didn't know what I wanted to do after writing the tree generation code for a while. That tree can be used for anything.

• NOTE: people switching to the no_helpers branch should read this README too. It has all the information you need to work with the tree.

FUNCTIONS YOU NEED TO USE TO INTERACT WITH THE TREE-

1. struct dnode *init_tree(char *absolute_location_of_dir) - this creates the tree.

2. struct fnode *find_fnode_abs(struct dnode *tree, char *absolute_location_of_file) - this will return the fnode corresponding to a file.

3. int write_abs(struct dnode *tree, char *absolute_location_of_file, char *content) - this will write to a file, wont append.

4. struct str_blk *read_abs(struct dnode *tree, char *absolute_location_of_file) - this will return the content of a file(str_blk explained below with all the structs).

STRUCTURES YOU NEED AN UNDERSTANDING OF-

fnode

struct fnode{
    char *location;
    struct str_blk *text; 
    struct stat st;
};

• This is the structure in the tree that contains the file. Location is absolute.

dnode

struct dnode{
    char *location; 
    struct stat st;
    struct dnode *parent;
    struct dnode_list *dlist; 
    struct fnode_list *flist;
};

• This is the structure in the tree that contains the directory. Location is absolute. dnode_list, fnode_list explained below.

dnode_list

struct dnode_list{
    struct dnode *val;
    struct dnode_list *next;
};

• This is just a linked list of sub-directories in a dnode

fnode_list

struct fnode_list{
    struct fnode *val;
    struct fnode_list *next;
};

• This is just a linked list of files in a dnode

str_blk

struct str_blk{
    char *content;
    struct str_blk *next;
};

• This is how the tree stores text, Instead of one big buffer, the program creates a linked list of blocks of text, with predefined size (BLK_SIZE defined in str_ll.h)

CORE FUNCTIONALITY HAS BEEN ADDED. Will only return to make file creation and directory creation after I feel the need to prove to myself that I am good at something
