Issue #16001 has been updated by chrisseaton (Chris Seaton). > If so, it seems like a very heavy handed way to shorten something that is already fairly short For some reason nobody seems to have commented here what I think is the original motivation for this new method - it's not an alias for brevity, it's a performance thing. Getting the full backtrace is extremely expensive and nobody has a good idea how to make it fully lazy. This new method allows the user to explicitly say that they only need some of the callers. ---------------------------------------- Feature #16001: Provide an alias to Kernel#caller_locations(1,1) and Kernel#caller(1,1) https://bugs.ruby-lang.org/issues/16001#change-79404 * Author: piotrmurach (Piotr Murach) * Status: Open * Priority: Normal * Assignee: * Target version: ---------------------------------------- As it is common to use `caller_locations(1,1)` and `caller(1,1)`, this proposes an alias to help get the previous backtrace frame and avoid common beginner mistakes getting full backtrace information. The currently suggestions are: * `immediate_caller` * `caller_first` * `caller_only` This feature request is based on conversation with Charles Nutter who says: > This is such a common thing... maybe we need to add something like #caller_only or #caller1 that basically do caller(1,1). -- 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>
