Open3.capture2e captures the standard output and the standard error of a command.

stdout_and_stderr_str, status = Open3.capture2e([env,] cmd... [, opts])

The arguments env, cmd and opts are passed to Open3.popen3 except opts[:stdin_data] and opts[:binmode]. See Process.spawn.

If opts[:stdin_data] is specified, it is sent to the command’s standard input.

If opts[:binmode] is true, internal pipes are set to binary mode.

Example:

# capture make log
make_log, s = Open3.capture2e("make")

The directory prefix this RubyGems was installed at. If your prefix is in a standard location (ie, rubygems is installed where you’d expect it to be), then prefix returns nil.

Determines whether the given ‘requirement` is satisfied by the given `spec`, in the context of the current `activated` dependency graph.

@param [Object] requirement @param [DependencyGraph] activated the current dependency graph in the

resolution process.

@param [Object] spec @return [Boolean] whether ‘requirement` is satisfied by `spec` in the

context of the current `activated` dependency graph.

@return [Array<Object>] the list of requirements that led to

`requirement` being required.

Return the length of the hash value in bytes.

ptr.to_str        => string
ptr.to_str(len)   => string

Returns the pointer contents as a string.

When called with no arguments, this method will return the contents with the length of this pointer’s size.

When called with len, a string of len bytes will be returned.

See to_s

Returns the output size of the digest, i.e. the length in bytes of the final message digest result.

Example

digest = OpenSSL::Digest::SHA1.new
puts digest.digest_length # => 20

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     ]

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

See Psych::Handler#start_document

This method is called when a parse error is found.

ERROR_TOKEN_ID is an internal ID of token which caused error. You can get string representation of this ID by calling token_to_str.

ERROR_VALUE is a value of error token.

value_stack is a stack of symbol values. DO NOT MODIFY this object.

This method raises ParseError by default.

If this method returns, parsers enter “error recovering mode”.

This method is called when some event handler is undefined. event is :on_XXX, token is the scanned token, and data is a data accumulator.

The return value of this method is passed to the next event handler (as of Enumerable#inject).
