Returns whether or not the given entry point func can be found within lib. If func is nil, the main() entry point is used by default. If found, it adds the library to list of libraries to be used when linking your extension.
If headers are provided, it will include those header files as the header files it looks in when searching for func.
The real name of the library to be linked can be altered by --with-FOOlib configuration option.
Returns whether or not the entry point func can be found within the library lib in one of the paths specified, where paths is an array of strings. If func is nil , then the main() function is used as the entry point.
If lib is found, then the path it was found on is added to the list of library paths searched and linked against.
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.
Returns the signedness of the given type. You may optionally specify additional headers to search in for the type.
If the type is found and is a numeric type, a macro is passed as a preprocessor constant to the compiler using the type name, in uppercase, prepended with SIGNEDNESS_OF_, followed by the type name, followed by =X where “X” is positive integer if the type is unsigned and a negative integer if the type is signed.
For example, if size_t is defined as unsigned, then check_signedness('size_t') would return +1 and the SIGNEDNESS_OF_SIZE_T=+1 preprocessor macro would be passed to the compiler. The SIGNEDNESS_OF_INT=-1 macro would be set for check_signedness('int')
Basically a wrapper for Process.spawn that:
Creates a child process for each of the given cmds by calling Process.spawn.
Does not wait for child processes to exit.
With no block given, returns an array of the wait threads for all of the child processes.
Example:
wait_threads = Open3.pipeline_start('ls', 'grep R') # => [#<Process::Waiter:0x000055e8de9d2bb0 run>, #<Process::Waiter:0x000055e8de9d2890 run>] wait_threads.each do |wait_thread| wait_thread.join end
Output:
Rakefile README.md
With a block given, calls the block with an array of the wait processes:
Open3.pipeline_start('ls', 'grep R') do |wait_threads| wait_threads.each do |wait_thread| wait_thread.join end end
Output:
Rakefile README.md
Like Process.spawn, this method has potential security vulnerabilities if called with untrusted input; see Command Injection.
If the first argument is a hash, it becomes leading argument env in each call to Process.spawn; see Execution Environment.
If the last argument is a hash, it becomes trailing argument options in each call to Process.spawn; see Execution Options.
Each remaining argument in cmds is one of:
A command_line: a string that begins with a shell reserved word or special built-in, or contains one or more metacharacters.
An exe_path: the string path to an executable to be called.
An array containing a command_line or an exe_path, along with zero or more string arguments for the command.

returns array of WIN32OLE::Param object corresponding with method parameters.
tobj = WIN32OLE::Type.new('Microsoft Excel 9.0 Object Library', 'Workbook')
method = WIN32OLE::Method.new(tobj, 'SaveAs')
p method.params # => [Filename, FileFormat, Password, WriteResPassword,
ReadOnlyRecommended, CreateBackup, AccessMode,
ConflictResolution, AddToMru, TextCodepage,

Changes the parameters of the deflate stream to allow changes between different types of data that require different types of compression. Any unprocessed data is flushed before changing the params.
See Zlib::Deflate.new for a description of level and strategy.
Returns true if URI is hierarchical.
URI has components listed in order of decreasing significance from left to right, see RFC3986 www.rfc-editor.org/rfc/rfc3986 1.2.3.
require 'uri' uri = URI.parse("http://my.example.com/") uri.hierarchical? #=> true uri = URI.parse("mailto:joe@example.com") uri.hierarchical? #=> false
Returns URL-unescaped string following RFC 3986.
URL-decode a string following RFC 3986 with encoding(optional).
string = CGI.unescapeURIComponent("%27Stop%21%27+said%20Fred") # => "'Stop!'+said Fred"
Set all the parameters.
Delegates to the start_character_offset of the associated location object.
Delegates to the start_character_column of the associated location object.
The character offset from the beginning of the source where this location starts.
The column number in characters where this location ends from the start of the line.
Create a new ForwardingParameterNode node.
Responsible for finding the nearest targets to the given comment within the context of the given encapsulating node.
Dispatch enter and leave events for ForwardingParameterNode nodes and continue walking the tree.
