The standard configuration object for gems.
Use the given configuration object (which implements the ConfigFile
protocol) as the standard configuration object.
Returns an Array
of sources to fetch remote gems from. Uses default_sources
if the sources list is empty.
Need to be able to set the sources without calling Gem.sources
.replace since that would cause an infinite loop.
DOC: This comment is not documentation about the method itself, it’s more of a code comment about the implementation.
Performs a Miller-Rabin probabilistic primality test for bn

parameter is deprecated in version 3.0. It has no effect.
Write data to a registry value named name. When name is nil, write to the ‘default’ value.
type is type value. (see Registry::Constants
module) Class
of data must be same as which read
method returns.
Write value to a registry value named name.
The value type is REG_SZ(write_s
), REG_DWORD(write_i
), or REG_BINARY(write_bin
).

Returns help string of OLE method. If the help string is not found, then the method returns nil.
tobj = WIN32OLE_TYPE.new('Microsoft Internet Controls', 'IWebBrowser') method = WIN32OLE_METHOD.new(tobj, 'Navigate') puts method.helpstring # => Navigates to a URL or file.
Returns help string.
tobj = WIN32OLE_TYPE.new('Microsoft Internet Controls', 'IWebBrowser') puts tobj.helpstring # => Web Browser interface
Returns array of WIN32OLE_VARIABLE objects which represent variables defined in OLE class.
tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'XlSheetType') vars = tobj.variables vars.each do |v| puts "#{v.name} = #{v.value}" end The result of above sample script is follows: xlChart = -4109 xlDialogSheet = -4116 xlExcel4IntlMacroSheet = 4 xlExcel4MacroSheet = 3 xlWorksheet = -4167

Returns true

File.stat("testfile").writable? #=> true
Writes length
bytes from buffer into io
, starting at offset
in the buffer. If an error occurs, return -errno
.
If offset
is not given, the bytes are taken from the beginning of the buffer.
out = File.open('output.txt', 'wb') IO::Buffer.for('1234567').write(out, 3)
This leads to 123
being written into output.txt
Writes length
bytes from buffer into io
, starting at offset
in the buffer. If an error occurs, return -errno
.
If offset
is not given, the bytes are taken from the beginning of the buffer. If the offset
is given and is beyond the end of the file, the gap will be filled with null (0 value) bytes.
out = File.open('output.txt', File::RDWR) # open for read/write, no truncation IO::Buffer.for('1234567').pwrite(out, 2, 3, 1)
This leads to 234
(3 bytes, starting from position 1) being written into output.txt
, starting from file position 2.
Produces the summary text. Each line of the summary is yielded to the block (without newline).
sdone
Already summarized short style options keyed hash.
ldone
Already summarized long style options keyed hash.
width
Width of left side (option part). In other words, the right side (description part) starts after width
columns.
max
Maximum width of left side -> the options are filled within max
columns.
indent
Prefix string indents all summarized lines.
Creates the summary table, passing each line to the block
(without newline). The arguments args
are passed along to the summarize method which is called on every option.
