    trace_object_allocations do

Parse a YAML string in yaml. Returns the Psych::Nodes::Stream. This method can handle multiple YAML documents contained in yaml. filename is used in the exception message if a Psych::SyntaxError is raised.

If a block is given, a Psych::Nodes::Document node will be yielded to the block as it’s being parsed.

Raises a Psych::SyntaxError when a YAML syntax error is detected.

Example:

Psych.parse_stream("---\n - a\n - b") # => #<Psych::Nodes::Stream:0x00>

Psych.parse_stream("--- a\n--- b") do |node|
  node # => #<Psych::Nodes::Document:0x00>
end

begin
  Psych.parse_stream("--- `", "file.txt")
rescue Psych::SyntaxError => ex
  ex.file    # => 'file.txt'
  ex.message # => "(file.txt): found character that cannot start any token"
end

Returns whether or not the given framework can be found on your system. If found, a macro is passed as a preprocessor constant to the compiler using the framework name, in uppercase, prepended with HAVE_FRAMEWORK_.

For example, if have_framework('Ruby') returned true, then the HAVE_FRAMEWORK_RUBY preprocessor macro would be passed to the compiler.

If fw is a pair of the framework name and its header file name that header file is checked, instead of the normally used header file which is named same as the framework.

Constructs proper parameters from arguments

A private helper method

record class_name for the supplied uri and tag_name

The full path to the gem (install path + full name).

Full paths in the gem to add to $LOAD_PATH when this gem is activated.

The name of the configuration file.

Removes the gemspec matching full_name from the dependency list

Split the Gem search path (as reported by Gem.path).

Find the best specification matching a name and requirements. Raises if the dependency doesn’t resolve to a valid specification.

Return the best specification that contains the file matching path.
