The mode needed to read a file as straight binary.
Returns a list of paths matching glob that can be used by a gem to pick up features from other gems. For example:
Gem.find_files('rdoc/discover').each do |path| load path end
if check_load_path is true (the default), then find_files also searches $LOAD_PATH for files as well as gems.
Note that find_files will return all files even if they are from different versions of the same gem. See also find_latest_files
Finds the user’s home directory.
Adds a post-build hook that will be passed an Gem::Installer instance when Gem::Installer#install is called. The hook is called after the gem has been extracted and extensions have been built but before the executables or gemspec has been written. If the hook returns false then the gem’s files will be removed and the install will be aborted.
Adds a hook that will get run after Gem::Specification.reset is run.
Safely read a file in binary mode on all platforms.
Is this a windows platform?
Find the ‘rubygems_plugin’ files in the latest installed gems and load them
The default directory for binaries
Allows toggling Windows behavior. This method is available when requiring ‘rubygems/test_case’
Returns the time resolution returned by POSIX clock_getres() function.
clock_id specifies a kind of clock. See the document of Process.clock_gettime for details.
clock_id can be a symbol as Process.clock_gettime. However the result may not be accurate. For example, +Process.clock_getres(:GETTIMEOFDAY_BASED_CLOCK_REALTIME)+ returns 1.0e-06 which means 1 microsecond, but actual resolution can be more coarse.
If the given clock_id is not supported, Errno::EINVAL is raised.
unit specifies a type of the return value. Process.clock_getres accepts unit as Process.clock_gettime. The default value, :float_second, is also same as Process.clock_gettime.
Process.clock_getres also accepts :hertz as unit. :hertz means a the reciprocal of :float_second.
:hertz can be used to obtain the exact value of the clock ticks per second for times() function and CLOCKS_PER_SEC for clock() function.
+Process.clock_getres(:TIMES_BASED_CLOCK_PROCESS_CPUTIME_ID, :hertz)+ returns the clock ticks per second.
+Process.clock_getres(:CLOCK_BASED_CLOCK_PROCESS_CPUTIME_ID, :hertz)+ returns CLOCKS_PER_SEC.
p Process.clock_getres(Process::CLOCK_MONOTONIC) #=> 1.0e-09
