Issue #20335 has been updated by byroot (Jean Boussier).
I think omitting the first N frames is useful.
Agreed, that's the only one I want. The reason I started the issue by asking for the same parameters is purely consistency. Now, if there are valid reasons not to support some (like you exposed), I'm totally fine with deliberately not supporting them. But what I'm trying to say is we should start with the same feature set and then selectively remove the one that may be problematic. So I suppose at that stage the proposal would be: ```ruby Thread.each_caller_location(1) # skip first frame Thread.each_caller_location(1, 20) # skip first frame, yield the next 20 frames Thread.each_caller_location(1..20) # ArgumentError ``` Is that correct? ---------------------------------------- Feature #20335: `Thread.each_caller_location` should accept the same arguments as `caller` and `caller_locations` https://bugs.ruby-lang.org/issues/20335#change-107270 * Author: byroot (Jean Boussier) * Status: Open ---------------------------------------- `Thread.each_caller_location` was added to Ruby 3.2 as part of [Feature #16663] and is a very useful API for emitting warnings with a proper source location and similar use cases. However in many of the cases where I used it, or seen it used, it was needed to skip the first, or a couple frames: Examples: Sorbet: https://github.com/Shopify/sorbet/blob/b27a14c247ace7cabdf0f348bfb11fdf0b7e9... ```ruby def self.find_caller skiped_first = false Thread.each_caller_location do |loc| unless skiped_first skiped_first = true next end next if loc.path&.start_with?("<internal:") return loc if yield(loc) end nil end ``` @fxn 's PR: https://github.com/ruby/ruby/blob/9c2e686719a5a4df5ea0b8a3b6a373ca6003c229/l... ```ruby frames_to_skip = 2 location = nil Thread.each_caller_location do |cl| if frames_to_skip >= 1 frames_to_skip -= 1 next end # snipp... ``` ### Proposal I think it would be very useful if `Thread.each_caller_location` accepted the same arguments as `caller` and `caller_locations`: ```ruby #each_caller_location(start = 1, length = nil) #each_caller_location(range) ``` @jeremyevans0 what do you think? -- https://bugs.ruby-lang.org/
