Immediately evaluate multiple lines of code at same time in rails console when using pry?

问题 Suppose we have pry installed, open the rails console, and run times = [1, 5, 10, 30, 72].sample(1)[0] nums = *(1..72) num_sample = nums.sample(times) Evaluation stops after line 2 (since the output of the second line runs off screen and hence the console opens the output): How can we get the console to not stop executing, but rather display the entirety of the output of one line before executing the next, that is, to execute all lines of code it receives? Is there any way to achieve this

IEx Pry: Always allow?

由 旧巷老猫 提交于 2020-08-19 11:36:41
问题 When I run Elixir code with my debugger, Pry, then it always confronts me with Allow? [Yn] Can I pass a configuration option to always allow this? Thus, by default? Why is this question asked? What could be harmful? 回答1: No, you cannot provide an option to allow without manual confirmation. The confirmation is a reused component of IEx, any terminal takeover messages ( :take ) require user confirmation. This take over flow also happens in IEx.pry/0. As for why this is the case, I am not sure.

How is the ls command in Pry able to accept -l as an argument?

由 自闭症网瘾萝莉.ら 提交于 2020-07-22 06:02:30
问题 I recently discovered that ls in pry can take an argument like so: ls -l . My initial question is what the -l part actually is - it is clearly not a string or symbol, and there is no local variable or method l defined, so is there something else going on behind the scenes? As an extension to my question, is ls just a "normal" Ruby method defined by pry, or does it behave slightly differently? I also noted that you get a different output if you pass a string ( ls 'l' ) or symbol ( ls :l ). Is

Enable stack dump on exception in Rails console

由 核能气质少年 提交于 2020-01-23 05:00:18
问题 I am using Ruby on Rails with the pry gem. When an error occurs during a rake task, I get a very nice stack trace. When however I do something in my rails console that triggers an exception, I only get to see the error message and the one line of code that triggered it (which most of the time is somewhere in the rails core). Is there a way to enable these stack dumps in the console? 回答1: I found a solution myself. Apparently, I was in need of the command wtf? that comes with pry. [7] project

Pry-Remote with Pow on Rails 4

由 百般思念 提交于 2020-01-13 02:44:28
问题 I'm busy with (finally) upgrading to Rails 4 and I've run into a problem with Pry-remote. Problem: When added binding.remote_pry to my code it breaks the code but when I can't get into the debugger by typing pry-remote . This used to work when running Rails 3 and Ruby 1.9.3. Side note: When running Rails s instead of Pow and binding.pry instead binding.remote_pry , it falls into the debugger. What I'm running: Pow 0.5.0 ruby 2.1.5p273 Rails 4.2.0 OSX 10.9.5 Gemfile gem 'pry' gem 'pry-remote'

Is there a way to use a keystroke to invoke the pry ruby gem?

由 送分小仙女□ 提交于 2020-01-01 18:43:10
问题 I was just thinking about how great it would be to be able to run a program and then hit a keystroke to invoke pry and debug. Maybe there is a gem out there that injects binding.pry dynamically during runtime that I don't know about. If there isn't, how would you make a keystroke that inserts binding.pry before the next line of ruby script that is about to execute? 回答1: Assuming a POSIX OS, you could try adding a signal handler in your ruby program. The ruby documentation even gives an

Get pry to display characters like [äöüßÄÖÜß] (utf-8 encoding)? (Possibly Windows-specific issue?)

由 一曲冷凌霜 提交于 2019-12-30 06:59:19
问题 [ All the scripts I'm working with with these German characters are in UTF-8 themselves, have #encoding: utf-8 at the top (and Encoding.external_default = 'utf-8' , not that that's really relevant I think because German chars in strings that are defined within the script don't get displayed right.) ] All these things display fine at the windows command prompt and using irb etc. I can't even enter these characters at the pry prompt, though. Attempting to paste in puts "äöüÄÖÜß" gets puts " .
