Results for: "partition"

Returns a parse result whose value is an array of tokens that closely resembles the return value of Ripper::lex. The main difference is that the ‘:on_sp` token is not emitted.

For supported options, see Prism::parse.

SyntaxSuggest.valid_without? [Private]

This will tell you if the ‘code_lines` would be valid if you removed the `without_lines`. In short it’s a way to detect if we’ve found the lines with syntax errors in our document yet.

code_lines = [
  CodeLine.new(line: "def foo\n",   index: 0)
  CodeLine.new(line: "  def bar\n", index: 1)
  CodeLine.new(line: "end\n",       index: 2)
]

SyntaxSuggest.valid_without?(
  without_lines: code_lines[1],
  code_lines: code_lines
)                                    # => true

SyntaxSuggest.valid?(code_lines) # => false

The iterator version of the tsort method. obj.tsort_each is similar to obj.tsort.each, but modification of obj during the iteration may lead to unexpected results.

tsort_each returns nil. If there is a cycle, TSort::Cyclic is raised.

class G
  include TSort
  def initialize(g)
    @g = g
  end
  def tsort_each_child(n, &b) @g[n].each(&b) end
  def tsort_each_node(&b) @g.each_key(&b) end
end

graph = G.new({1=>[2, 3], 2=>[4], 3=>[2, 4], 4=>[]})
graph.tsort_each {|n| p n }
#=> 4
#   2
#   3
#   1

The iterator version of the TSort.tsort method.

The graph is represented by each_node and each_child. each_node should have call method which yields for each node in the graph. each_child should have call method which takes a node argument and yields for each child node.

g = {1=>[2, 3], 2=>[4], 3=>[2, 4], 4=>[]}
each_node = lambda {|&b| g.each_key(&b) }
each_child = lambda {|n, &b| g[n].each(&b) }
TSort.tsort_each(each_node, each_child) {|n| p n }
#=> 4
#   2
#   3
#   1

Sets the minimum and maximum supported protocol versions. See min_version= and max_version=.

foo(&bar)

^^^^

Visit the arguments and block of a call node and return the arguments and block as they should be used.

foo.bar, = 1 ^^^^^^^

foo => bar => baz

^^^^^^^^^^

Foo ^^^

“foo #@bar”

^^^^^

foo => [*, bar, *]

^^^^^^^^^^^

super ^^^^^

super {} ^^^^^^^^

foo => {}

^^

foo { |bar,| }

^

foo, = 1 ^^^^^^^^

/(?<foo>foo)/ =~ bar ^^^^^^^^^^^^^^^^^^^^

foo = 1 and bar => ^foo

^^^^
