Emit a scalar with value
Called when a scalar value is found. The scalar may have an anchor, a tag, be implicitly plain or implicitly quoted
value is the string value of the scalar anchor is an associated anchor or nil tag is an associated tag or nil plain is a boolean value quoted is a boolean value style is an integer idicating the string style
See the constants in Psych::Nodes::Scalar for the possible values of style
Here is a YAML document that exercises most of the possible ways this method can be called:
--- - !str "foo" - &anchor fun - many lines - | many newlines
The above YAML document contains a list with four strings. Here are the parameters sent to this method in the same order:
# value anchor tag plain quoted style ["foo", nil, "!str", false, false, 3 ] ["fun", "anchor", nil, true, false, 1 ] ["many lines", nil, nil, true, false, 1 ] ["many\nnewlines\n", nil, nil, false, true, 4 ]
Parse the YAML document contained in yaml. Events will be called on the handler set on the parser instance.
See Psych::Parser and Psych::Parser#handler
Returns a Psych::Parser::Mark object that contains line, column, and index information.
Emit a scalar with value, anchor, tag, and a plain or quoted string type with style.
Another entry point for the parser. If you use this method, you must implement RECEIVER#METHOD_ID method.
RECEIVER#METHOD_ID is a method to get next token. It must ‘yield’ the token, which format is [TOKEN-SYMBOL, VALUE].
Enter error recovering mode. This method does not call on_error.
Leave error recovering mode.
The line number of the current token. This value starts from 1. This method is valid only in event handlers.
Starts the parser. init is a data accumulator and is passed to the next event handler (as of Enumerable#inject).
Returns the netmask address of ifaddr. nil is returned if netmask is not available in ifaddr.
Logs a message at the error (syslog warning) log level, or logs the message returned from the block.
Logs a message at the warn (syslog notice) log level, or logs the message returned from the block.
Creates a GzipReader or GzipWriter associated with io, passing in any necessary extra options, and executes the block with the newly created object just like File.open.
The GzipFile object will be closed automatically after executing the block. If you want to keep the associated IO object open, you may call Zlib::GzipFile#finish method in the block.
The line number of the last row read from this file.
Specify line number of the last row read from this file.
Resets the position of the file pointer to the point created the GzipReader object. The associated IO object needs to respond to the seek method.
Reads at most maxlen bytes from the gziped stream but it blocks only if gzipreader has no data immediately available. If the optional outbuf argument is present, it must reference a String, which will receive the data. It raises EOFError on end of file.

This is a deprecated alias for each_line.

Returns true if the effective user id of the process is the same as the owner of stat.
File.stat("testfile").owned? #=> true File.stat("/etc/passwd").owned? #=> false
