Returns the index of the current cursor position in Readline.line_buffer
.
The index in Readline.line_buffer
which matches the start of input-string passed to completion_proc
is computed by subtracting the length of input-string from Readline.point
.
start = (the length of input-string) - Readline.point
Raises NotImplementedError
if the using readline library does not support.
Set
the index of the current cursor position in Readline.line_buffer
.
Raises NotImplementedError
if the using readline library does not support.
See Readline.point
.
Returns an inspect() string summarizing the object state.
Decompresses string
. Raises a Zlib::NeedDict
exception if a preset dictionary is needed for decompression.
This method is almost equivalent to the following code:
def inflate(string) zstream = Zlib::Inflate.new buf = zstream.inflate(string) zstream.finish zstream.close buf end
See also Zlib.deflate
Return true
if the named file exists.
file_name can be an IO
object.
“file exists” means that stat() or fstat() system call is successful.
Deprecated method. Don’t use.
Returns true
if the named file is writable by the effective user and group id of this process. See eaccess(3).
Returns true
if the named file is a symbolic link.
Returns true
if the named file has the sticky bit set.
Initiates garbage collection, unless manually disabled.
This method is defined with keyword arguments that default to true:
def GC.start(full_mark: true, immediate_sweep: true); end
Use full_mark: false to perform a minor GC
. Use immediate_sweep: false to defer sweeping (use lazy sweep).
Note: These keyword arguments are implementation and version dependent. They are not guaranteed to be future-compatible, and may be ignored if the underlying implementation does not support them.
Returns a Hash
containing information about the GC
.
The hash includes information about internal statistics about GC
such as:
{ :count=>0, :heap_allocated_pages=>24, :heap_sorted_length=>24, :heap_allocatable_pages=>0, :heap_available_slots=>9783, :heap_live_slots=>7713, :heap_free_slots=>2070, :heap_final_slots=>0, :heap_marked_slots=>0, :heap_eden_pages=>24, :heap_tomb_pages=>0, :total_allocated_pages=>24, :total_freed_pages=>0, :total_allocated_objects=>7796, :total_freed_objects=>83, :malloc_increase_bytes=>2389312, :malloc_increase_bytes_limit=>16777216, :minor_gc_count=>0, :major_gc_count=>0, :remembered_wb_unprotected_objects=>0, :remembered_wb_unprotected_objects_limit=>0, :old_objects=>0, :old_objects_limit=>0, :oldmalloc_increase_bytes=>2389760, :oldmalloc_increase_bytes_limit=>16777216 }
The contents of the hash are implementation specific and may be changed in the future.
This method is only expected to work on C Ruby.
