### Public Class Methods

cleanpath(path) click to toggle source

Cleans a path by removing extraneous '..', '.' and '/' characters

@example Clean a path

    File.cleanpath('a/b//./c/../e') # => "a/b/e"

@param [String] path the path to clean @return [String] the sanitized path

    # File lib/yard/core_ext/file.rb, line 35
    def self.cleanpath(path)
      path = path.split(SEPARATOR)
      path = path.inject([]) do |acc, comp|
        next acc if comp == RELATIVE_SAMEDIR
        if comp == RELATIVE_PARENTDIR && acc.size > 0 && acc.last != RELATIVE_PARENTDIR
          acc.pop
          next acc
        end
        acc << comp
      end
      File.join(*path)
    end

open!(file, *args, &block) click to toggle source

Forces opening a file (for writing) by first creating the file's directory @param [String] file the filename to open @since 0.5.2

    # File lib/yard/core_ext/file.rb, line 53
    def self.open!(file, *args, &block)
      dir = dirname(file)
      FileUtils.mkdir_p(dir) unless directory?(dir)
      open(file, *args, &block)
    end

read_binary(file) click to toggle source

Reads a file with binary encoding @return [String] the ascii-8bit encoded data @since 0.5.3

    # File lib/yard/core_ext/file.rb, line 62
    def self.read_binary(file)
      File.open(file, 'rb') {|f| f.read }
    end

relative_path(from, to) click to toggle source

Turns a path `to` into a relative path from starting point `from`. The argument `from` is assumed to be a filename. To treat it as a directory, make sure it ends in +File::SEPARATOR+ ('/' on UNIX filesystems).

@param [String] from the starting filename

    (or directory with +from_isdir+ set to +true+).

@param [String] to the final path that should be made relative. @return [String] the relative path from `from` to `to`.

    # File lib/yard/core_ext/file.rb, line 18
    def self.relative_path(from, to)
      from = expand_path(from).split(SEPARATOR)
      to = expand_path(to).split(SEPARATOR)
      from.length.times do
        break if from[0] != to[0]
        from.shift; to.shift
      end
      from.pop
      join(*(from.map { RELATIVE_PARENTDIR } + to))
    end
