Instance Method Details

#compile_res(dir) ⇒ Object

compile_res: This function creates a hash representation of the file structure relative to <dir>. The values are either hashes (for directories) or strings (for files). The string values are the path to the file relative to @golfpath.

Example: compile_res(“#@golfpath/dir1”)

@golfpath/

|--dir1/
|    |--file1
|    |--file2
|    +--dir2/
|         |--file3
|         |--file4
|         +--dir3/
|              |--file5
|              +--file6
+--dir4/

{ 

file1 => "dir1/file1",
file2 => "dir1/file2",
dir2  => {
  file3 => "dir1/dir2/file3",
  file4 => "dir1/dir2/file4"
  dir3  => {
    file5 => "dir1/dir2/dir3/file5",
    file6 => "dir1/dir2/dir3/file6"
  }
