Issue #13626 has been updated by Eregon (Benoit Daloze). I think the underlying issue is we want a string append method which does not change the receiver's encoding (and instead raises an EncodingError if it would need to change it). ---------------------------------------- Feature #13626: Add String#byteslice! https://bugs.ruby-lang.org/issues/13626#change-98966 * Author: ioquatix (Samuel Williams) * Status: Open * Priority: Normal ---------------------------------------- It's a common pattern in IO buffering, to read a part of a string while leaving the remainder. ~~~ # Consume only part of the read buffer: result = @read_buffer.byteslice(0, size) @read_buffer = @read_buffer.byteslice(size, @read_buffer.bytesize) ~~~ It would be nice if this code could be simplified to: ~~~ result = @read_buffer.byteslice!(size) ~~~ Additionally, this allows a significantly improved implementation by the interpreter. -- https://bugs.ruby-lang.org/ Unsubscribe: <mailto:ruby-core-request@ruby-lang.org?subject=unsubscribe> <http://lists.ruby-lang.org/cgi-bin/mailman/options/ruby-core>
