Package fsnoder allows to create merkletrie noders that resemble file systems, from human readable string descriptions. Its intended use is generating noders in tests in a readable way.

For example:

root, _ = New("(a<1> b<2>, B(c<3> d()))")

will create a noder as follows:

  root        - "root" is an unnamed dir containing "a", "b" and "B".
  / | \       - "a" is a file containing the string "1".
 /  |  \      - "b" is a file containing the string "2".
a   b   B     - "B" is a directory containing "c" and "d".
       / \    - "c" is a file containing the string "3".
      c   d   - "D" is an empty directory.

Files are expressed as:

- one or more letters and dots for the name of the file

- a single number, between angle brackets, for the contents of the file.

- examples: a<1>, foo.go<2>.

Directories are expressed as:

- one or more letters for the name of the directory.

- its elements between parents, separated with spaces, in any order.

- (optionally) the root directory can be unnamed, by skiping its name.

Examples:

- D(a<1> b<2>) : two files, "a" and "b", having "1" and "2" as their respective contents, inside a directory called "D".

- A() : An empty directory called "A".

- A(b<>) : An directory called "A", with an empty file inside called "b":

- (b(c<1> d(e<2>)) f<>) : an unamed directory containing:

├── b              --> directory
│   ├── c          --> file containing "1"
│   └── d          --> directory
│       └── e      --> file containing "2"
└── f              --> empty file
