Called before each event with line/column information.
Parse and return a Time
from string
Returns a hash of default options used by the Ruby iseq compiler.
For details, see InstructionSequence.compile_option=
.
Sets the default values for various optimizations in the Ruby iseq compiler.
Possible values for options
include true
, which enables all options, false
which disables all options, and nil
which leaves all options unchanged.
You can also pass a Hash
of options
that you want to change, any options not present in the hash will be left unchanged.
Possible option names (which are keys in options
) which can be set to true
or false
include:
:inline_const_cache
:instructions_unification
:operands_unification
:peephole_optimization
:specialized_instruction
:stack_caching
:tailcall_optimization
Additionally, :debug_level
can be set to an integer.
These default options can be overwritten for a single run of the iseq compiler by passing any of the above values as the options
parameter to ::new
, ::compile
and ::compile_file
.
Iterates over each option, passing the option to the block
.
Add a command-line option and handler to the command.
See Gem::OptionParser#make_switch for an explanation of opts
.
handler
will be called with two values, the value of the argument and the options hash.
If the first argument of add_option
is a Symbol
, it’s used to group options in output. See ‘gem help list` for an example.
Remove previously defined command-line argument name
.
Mark a command-line option as deprecated, and optionally specify a deprecation horizon.
Note that with the current implementation, every version of the option needs to be explicitly deprecated, so to deprecate an option defined as
add_option('-t', '--[no-]test', 'Set test mode') do |value, options| # ... stuff ... end
you would need to explicitly add a call to ‘deprecate_option` for every version of the option you want to deprecate, like
deprecate_option('-t') deprecate_option('--test') deprecate_option('--no-test')
