/*
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
