Results for: "Data"

Called when the document starts with the declared version, tag_directives, if the document is implicit.

version will be an array of integers indicating the YAML version being dealt with, tag_directives is a list of tuples indicating the prefix and suffix of each tag, and implicit is a boolean indicating whether the document is started implicitly.

Example

Given the following YAML:

%YAML 1.1
%TAG ! tag:tenderlovemaking.com,2009:
--- !squee

The parameters for start_document must be this:

version         # => [1, 1]
tag_directives  # => [["!", "tag:tenderlovemaking.com,2009:"]]
implicit        # => false

Called when a sequence is started.

anchor is the anchor associated with the sequence or nil. tag is the tag associated with the sequence or nil. implicit a boolean indicating whether or not the sequence was implicitly started. style is an integer indicating the list style.

See the constants in Psych::Nodes::Sequence for the possible values of style.

Example

Here is a YAML document that exercises most of the possible ways this method can be called:

---
- !!seq [
  a
]
- &pewpew
  - b

The above YAML document consists of three lists, an outer list that contains two inner lists. Here is a matrix of the parameters sent to represent these lists:

# anchor    tag                       implicit  style
[nil,       nil,                      true,     1     ]
[nil,       "tag:yaml.org,2002:seq",  false,    2     ]
["pewpew",  nil,                      true,     1     ]

Called when a map starts.

anchor is the anchor associated with the map or nil. tag is the tag associated with the map or nil. implicit is a boolean indicating whether or not the map was implicitly started. style is an integer indicating the mapping style.

See the constants in Psych::Nodes::Mapping for the possible values of style.

Example

Here is a YAML document that exercises most of the possible ways this method can be called:

---
k: !!map { hello: world }
v: &pewpew
  hello: world

The above YAML document consists of three maps, an outer map that contains two inner maps. Below is a matrix of the parameters sent in order to represent these three maps:

# anchor    tag                       implicit  style
[nil,       nil,                      true,     1     ]
[nil,       "tag:yaml.org,2002:map",  false,    2     ]
["pewpew",  nil,                      true,     1     ]

Called before each event with line/column information.

Handles start_document events with version, tag_directives, and implicit styling.

See Psych::Handler#start_document

Start a stream emission with encoding

See Psych::Handler#start_stream

Start a document emission with YAML version, tags, and an implicit start.

See Psych::Handler#start_document

Start emitting a sequence with anchor, a tag, implicit sequence start and end, along with style.

See Psych::Handler#start_sequence

Start emitting a YAML map with anchor, tag, an implicit start and end, and style.

Returns the total bytes of the input data to the stream. FIXME

Returns the total bytes of the output data from the stream. FIXME

Returns true if stat is readable by the real user id of this process.

File.stat("testfile").readable_real?   #=> true

If stat is readable by others, returns an integer representing the file permission bits of stat. Returns nil otherwise. The meaning of the bits is platform dependent; on Unix systems, see stat(2).

m = File.stat("/etc/passwd").world_readable?  #=> 420
sprintf("%o", m)                              #=> "644"

Returns true if stat is writable by the real user id of this process.

File.stat("testfile").writable_real?   #=> true

If stat is writable by others, returns an integer representing the file permission bits of stat. Returns nil otherwise. The meaning of the bits is platform dependent; on Unix systems, see stat(2).

m = File.stat("/tmp").world_writable?         #=> 511
sprintf("%o", m)                              #=> "777"

Same as executable?, but tests using the real owner of the process.

Returns the absolute path of this instruction sequence.

nil if the iseq was evaluated from a string.

For example, using ::compile_file:

# /tmp/method.rb
def hello
  puts "hello, world"
end

# in irb
> iseq = RubyVM::InstructionSequence.compile_file('/tmp/method.rb')
> iseq.absolute_path #=> /tmp/method.rb

Paths in the gem to add to $LOAD_PATH when this gem is activated. If you have an extension you do not need to add "ext" to the require path, the extension build process will copy the extension files into “lib” for you.

The default value is "lib"

Usage:

# If all library files are in the root directory...
spec.require_paths = ['.']

Return the list of all array-oriented instance variables.

Return the list of all instance variables.
