* http://rubysideshow.rubyforge.org/irb_callbacks == DESCRIPTION: This gem adds callbacks to irb, intended for you to override at your discretion. == FEATURES: irb's control flow looks like this: loop: * prompt * eval * output This gem adds three callbacks to each phase. module IRB: * self.before_prompt * self.around_prompt (call yield) * self.after_prompt * self.before_eval * self.around_eval (call yield) * self.after_eval * self.before_output * self.around_output (call yield) * self.after_output == SYNOPSIS: # Here's my ~/.irbrc file (which is run at irb startup) require 'rubygems' require 'irb_callbacks' require 'benchmark' # This little snippet will time each command run via the console. module IRB def self.around_eval(&block) @timing = Benchmark.realtime do block.call end end def self.after_output puts "=> #{'%.3f' % @timing} seconds" end end # And a sample irb session: $ irb irb(main):001:0> 1_000_000.times { |x| x + 1 } => 1000000 => 0.330 seconds == CAVEATS: The three around_* callbacks all require you to call the block that's passed in. If you don't do it, undefined behavior may occur. == INSTALL: * sudo gem install irb_callbacks == LICENSE: (The MIT License) Copyright (c) 2008 Mike Judge Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the 'Software'), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.

Square Cube evaluator gem

I sometimes get a little descriptive with my variable names, so when you're doing a lot of work specifically with one object, it gets especially ugly and repetetive, making the code harder to read than it needs to be: @contract_participants_on_drugs.contract_id = params[:contract_id] @contract_participants_on_drugs.participant_name = params[:participant_name] @contract_participants_on_drugs.drug_conviction = DrugConvictions.find(:wtf => 'this is getting ridiculous') ... And so on. It gets ridiculous. Utility Belt implements a with(object) method via a change to Object: class Object #utility belt implementation def with(object, &block) object.instance_eval &block end end Unfortunately, that just executes the block in the context of the object, so there isn't any crossover, nor can you perform assignments with attr_accessors (that I was able to do, anyway). So, here's With.object() to fill the void. With.object(@foo) do a = "wtf" b = "this is not as bad" end In the above example, @foo.a and @foo.b are the variables getting set. If you prefer, you can require 'with_on_object' instead and use the notation with(object) do ... end. The tests in the /test directory offer more examples of what's been implemented and tested so far (except where noted - namely performing assignment to a variable that was declared outside the block, and is not on @foo). Not everything is working yet, but it works for the simplest, most common cases I've run up against. More complex tests are on the way, along with code to make them pass. Special thanks to Reg Braithwaite, for help and ideas along the way.

library to save away eval'ed code to a file first, so that it can be seen later [ex: while debugging]

## Why I have to develop this tool One of my ruby project is using bundler to manage gem dependencies. But the `Gemfile` is very complicate. It requires external `Gemfile` by using ruby `eval`. Because I have lots of similar projects that will use same piece of gems. So I decide to abstract these gems into a standalone `Gemfile`. And let those projects’ `Gemfile` loads it. The problem I met is when I building my docker image. I hope that image can pre-install all the ruby gems in that `Gemfile.lock`. Unluckily, `bundle install` require you must have the `Gemfile`. So I have to find out a way to revert `Gemfile.lock` to a usable `Gemfile`. So here we are!

provide Object#context_eval

Adds an `evaulate` refinement method to Proc and Object instances. The goal of this gem is to allow evaluation of variables, procs, and lambdas with the same level of flexibility. The `evaluate` method has been added to the Object class to simply return the value of the variable. The `evaluate` method is overriden on the Proc class to allow parameters to be passed to lambdas in the same flexible way as procs. This takes into consideration, required/optional/remaining parameters, and required/optional/remaining keyword parameters.

# ruby unshare (runshare) This tool allows to unshare Linux namespaces. The implementation is similar to the unshare(1) tool. ## Installation Add this line to your application's Gemfile: ```ruby gem 'runshare' ``` And then execute: $ bundle Or install it yourself as: $ gem install runshare ## Usage > require "runshare" > RUnshare::unshare For example: cat > test.rb require "runshare" pid = RUnshare::unshare( :clone_newpid => true, :clone_newns => true, :clone_newcgroup => true, :clone_newipc => true, :clone_newuts => true, :clone_newnet => true, :clone_newtime => true, :fork => true, :mount_proc => "/proc", # docker export $(docker create hello-world) | tar -xf - -C rootfs :root => "/tmp/rootfs" ) if pid == 0 # child puts "--- #{Process.pid}" if system("/hello") != true raise "bad" end puts "--- done" else # parent puts "-- unshare=#{pid}, pid=#{Process.pid}" puts "-- exit=#{Process.waitpid(pid)}" end ^D sudo ruby -I ./lib ./test.rb ## Quick start $ rake compile && echo 'require "runshare"; RUnshare::unshare(:clone_newuts => true)' | irb install -c tmp/x86_64-linux/runshare/2.4.10/runshare.so lib/runshare/runshare.so cp tmp/x86_64-linux/runshare/2.4.10/runshare.so tmp/x86_64-linux/stage/lib/runshare/runshare.so Switch to inspect mode. require "runshare"; RUnshare::unshare ## Ruby <2.5 If your app is single threaded and you are observing: eval:1: warning: pthread_create failed for timer: Invalid argument, scheduling broken Just ignore it with some degree of bravity. You also can silence it by setting: $VERBOSE = nil ## Development After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake spec` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment. To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org). ## Contributing Bug reports and pull requests are welcome on GitHub at https://github.com/sitano/runshare. This project is intended to be a safe, welcoming space for collaboration, and contributors are expected to adhere to the [Contributor Covenant](http://contributor-covenant.org) code of conduct. ## License The gem is available as open source under the terms of the [MIT License](https://opensource.org/licenses/MIT).

This gem will check if a coverage file meets the expected level. If it doesn't it will exit with a exit code of 1. This can be used in tools such as Jenkins to check if the coverage meets the expected level.

Evaluate block in the context of singleton class

Most existing gems that address command execution provide a limited interface or lack notable features. In contast, Exek seeks to provide comprehensive support for all of a program's exec needs with one thoughtfully-designed library. Intended features: - A "Command" class that encapsulates argv, env, and IO options, and process state. - Easy-to-use high level interfaces with sensible defaults for running commands to completion. - Comprehensive support for low-level concerns like piping, PTYs, and file descriptor magic. - Utilities for manipulating `sh` script strings, idiomatically building argument arrays, and generating reusable interaces for common system commands. - Tracing and introspection facilities for logging and latency analysis. - Safety: does not monkeypatch external modules, encourage mixins or use eval. Attempts to guide developers away from unsafe practices like shell scripts and shell injection.
