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.
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
.
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
.
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.
Start a document emission with YAML version
, tags
, and an implicit
start.
Start emitting a sequence with anchor
, a tag
, implicit
sequence start and end, along with style
.
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.
