Results for: "Pathname"

Wakes up the first thread in line waiting for this lock.

Returns the length of the queue.

Returns the length of the queue.

Returns the replacement string.

ec = Encoding::Converter.new("euc-jp", "us-ascii")
p ec.replacement    #=> "?"

ec = Encoding::Converter.new("euc-jp", "utf-8")
p ec.replacement    #=> "\uFFFD"

Sets the replacement string.

ec = Encoding::Converter.new("utf-8", "us-ascii", :undef => :replace)
ec.replacement = "<undef>"
p ec.convert("a \u3042 b")      #=> "a <undef> b"

Returns true if key is a key in self, otherwise false.

Returns the number of referenced objects

Parses the given string into an abstract syntax tree, returning the root node of that tree.

RubyVM::AbstractSyntaxTree.parse("x = 1 + 2")
# => #<RubyVM::AbstractSyntaxTree::Node:SCOPE@1:0-1:9>

If keep_script_lines: true option is provided, the text of the parsed source is associated with nodes and is available via Node#script_lines.

If keep_tokens: true option is provided, Node#tokens are populated.

SyntaxError is raised if the given string is invalid syntax. To overwrite this behavior, error_tolerant: true can be provided. In this case, the parser will produce a tree where expressions with syntax errors would be represented by Node with type=:ERROR.

root = RubyVM::AbstractSyntaxTree.parse("x = 1; p(x; y=2")
# <internal:ast>:33:in `parse': syntax error, unexpected ';', expecting ')' (SyntaxError)
# x = 1; p(x; y=2
#           ^

root = RubyVM::AbstractSyntaxTree.parse("x = 1; p(x; y=2", error_tolerant: true)
# (SCOPE@1:0-1:15
#  tbl: [:x, :y]
#  args: nil
#  body: (BLOCK@1:0-1:15 (LASGN@1:0-1:5 :x (LIT@1:4-1:5 1)) (ERROR@1:7-1:11) (LASGN@1:12-1:15 :y (LIT@1:14-1:15 2))))
root.children.last.children
# [(LASGN@1:0-1:5 :x (LIT@1:4-1:5 1)),
#  (ERROR@1:7-1:11),
#  (LASGN@1:12-1:15 :y (LIT@1:14-1:15 2))]

Note that parsing continues even after the errored expression.

Escape only the tags of certain HTML elements in string.

Takes an element or elements or array of elements. Each element is specified by the name of the element, without angle brackets. This matches both the start and the end tag of that element. The attribute list of the open tag will also be escaped (for instance, the double-quotes surrounding attribute values).

print CGI.escapeElement('<BR><A HREF="url"></A>', "A", "IMG")
  # "<BR>&lt;A HREF=&quot;url&quot;&gt;&lt;/A&gt"

print CGI.escapeElement('<BR><A HREF="url"></A>', ["A", "IMG"])
  # "<BR>&lt;A HREF=&quot;url&quot;&gt;&lt;/A&gt"

Undo escaping such as that done by CGI.escapeElement()

print CGI.unescapeElement(
        CGI.escapeHTML('<BR><A HREF="url"></A>'), "A", "IMG")
  # "&lt;BR&gt;<A HREF="url"></A>"

print CGI.unescapeElement(
        CGI.escapeHTML('<BR><A HREF="url"></A>'), ["A", "IMG"])
  # "&lt;BR&gt;<A HREF="url"></A>"

Updates the digest using a given string and returns self.

The update() method and the left-shift operator are overridden by each implementation subclass. (One should be an alias for the other)

Returns digest_obj.digest_length().

Construct a new class given a C:

• class klass (CUnion, CStruct, or other that provide an entity_class)

• types (Fiddle::TYPE_INT, Fiddle::TYPE_SIZE_T, etc., see the C types constants)

• corresponding members

Fiddle::Importer#struct and Fiddle::Importer#union wrap this functionality in an easy-to-use manner.

Examples:

require 'fiddle/struct'
require 'fiddle/cparser'

include Fiddle::CParser

types, members = parse_struct_signature(['int i','char c'])

MyStruct = Fiddle::CStructBuilder.create(Fiddle::CUnion, types, members)

MyStruct.malloc(Fiddle::RUBY_FREE) do |obj|
  ...
end

obj = MyStruct.malloc(Fiddle::RUBY_FREE)
begin
  ...
ensure
  obj.call_free
end

obj = MyStruct.malloc
begin
  ...
ensure
  Fiddle.free obj.to_ptr
end

See IO#getpass.

Similar to read, but raises EOFError at end of string instead of returning nil, as well as IO#sysread does.

Reads at most maxlen bytes from the stream. If buf is provided it must reference a string which will receive the data.

See IO#readpartial for full details.

Return true if the PRNG has been seeded with enough data, false otherwise.

The current status of GC profile mode.

Starts the GC profiler.

Returns whether the form contained multipart/form-data

Parses self destructively and returns self containing the rest arguments left unparsed.
