| 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 |
