If there is one it will download it and install it in your project avoiding the need to run carthage bootstrap. ----------------------Thanks Mr.Blas but now we are facing dependency conflict with Fastlane 2.144-------------------- What I want to solve: Dependency conflict with Fastlane 2.144 What I did: 1. Changed name of this gem to "carthage_cache_res" 2. Fixed runtime dependencies: aws-sdk < 3, commander = 4.3.8 3. Changed system dependency versions: ruby > 2.6, xcode 11.x
This gem provides Deconstructable, a mixin module that helps you to support pattern-matching over your types. Usage -------- ``` class Thing include Deconstructable ... deconstructable :x, :y deconstructable def foo do_the_foo end end ``` This class provides a single DSL method `deconstructable` which helps you to mark methods and attributes as deconstructable. Deconstructable attributes will be made available in pattern matching, e.g.: ``` thing in Thing(foo:, x: 100, y:) ``` Classes that include `Deconstructable` gain an implementation of `deconstruct_keys` that permits hash-style key based pattern matching. Positional array-style patterns are not supported.

The affixapi.com API documentation. # Introduction Affix API is an OAuth 2.1 application that allows developers to access customer data, without developers needing to manage or maintain integrations; or collect login credentials or API keys from users for these third party systems. # OAuth 2.1 Affix API follows the [OAuth 2.1 spec](https://datatracker.ietf.org/doc/html/draft-ietf-oauth-v2-1-08). As an OAuth application, Affix API handles not only both the collection of sensitive user credentials or API keys, but also builds and maintains the integrations with the providers, so you don't have to. # How to obtain an access token in order to get started, you must: - register a `client_id` - direct your user to the sign in flow (`https://connect.affixapi.com` [with the appropriate query parameters](https://github.com/affixapi/starter-kit/tree/master/connect)) - capture `authorization_code` we will send to your redirect URI after the sign in flow is complete and exchange that `authorization_code` for a Bearer token # Sandbox keys (developer mode) ### dev ``` eyJhbGciOiJFUzI1NiIsImtpZCI6Ims5RmxwSFR1YklmZWNsUU5QRVZzeFcxazFZZ0Zfbk1BWllOSGVuOFQxdGciLCJ0eXAiOiJKV1MifQ.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.VLWYjCQvBS0C3ZA6_J3-U-idZj5EYI2IlDdTjAWBxSIHGufp6cqaVodKsF2BeIqcIeB3P0lW-KL9mY3xGd7ckQ ``` #### `employees` endpoint sample: ``` curl --fail \ -X GET \ -H 'Authorization: Bearer eyJhbGciOiJFUzI1NiIsImtpZCI6Ims5RmxwSFR1YklmZWNsUU5QRVZzeFcxazFZZ0Zfbk1BWllOSGVuOFQxdGciLCJ0eXAiOiJKV1MifQ.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.VLWYjCQvBS0C3ZA6_J3-U-idZj5EYI2IlDdTjAWBxSIHGufp6cqaVodKsF2BeIqcIeB3P0lW-KL9mY3xGd7ckQ' \ 'https://dev.api.affixapi.com/2023-03-01/developer/employees' ``` ### prod ``` eyJhbGciOiJFUzI1NiIsImtpZCI6Ims5RmxwSFR1YklmZWNsUU5QRVZzeFcxazFZZ0Zfbk1BWllOSGVuOFQxdGciLCJ0eXAiOiJKV1MifQ.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.2zdpFAmiyYiYk6MOcbXNUwwR4M1Fextnaac340x54AidiWXCyw-u9KeavbqfYF6q8a9kcDLrxhJ8Wc_3tIzuVw ``` #### `employees` endpoint sample: ``` curl --fail \ -X GET \ -H 'Authorization: Bearer eyJhbGciOiJFUzI1NiIsImtpZCI6Ims5RmxwSFR1YklmZWNsUU5QRVZzeFcxazFZZ0Zfbk1BWllOSGVuOFQxdGciLCJ0eXAiOiJKV1MifQ.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.2zdpFAmiyYiYk6MOcbXNUwwR4M1Fextnaac340x54AidiWXCyw-u9KeavbqfYF6q8a9kcDLrxhJ8Wc_3tIzuVw' \ 'https://api.affixapi.com/2023-03-01/developer/employees' ``` # Webhooks An exciting feature for HR/Payroll modes are webhooks. If enabled, your `webhook_uri` is set on your `client_id` for the respective environment: `dev | prod` Webhooks are configured to make live requests to the underlying integration 1x/hr, and if a difference is detected since the last request, we will send a request to your `webhook_uri` with this shape: ``` { added: <api.v20230301.Employees>[ <api.v20230301.Employee>{ ..., date_of_birth: '2010-08-06', display_full_name: 'Daija Rogahn', employee_number: '57993', employment_status: 'pending', employment_type: 'other', employments: [ { currency: 'eur', effective_date: '2022-02-25', employment_type: 'other', job_title: 'Dynamic Implementation Manager', pay_frequency: 'semimonthly', pay_period: 'YEAR', pay_rate: 96000, }, ], first_name: 'Daija', ... } ], removed: [], updated: [ <api.v20230301.Employee>{ ..., date_of_birth: '2009-11-09', display_full_name: 'Lourdes Stiedemann', employee_number: '63189', employment_status: 'leave', employment_type: 'full_time', employments: [ { currency: 'gbp', effective_date: '2023-01-16', employment_type: 'full_time', job_title: 'Forward Brand Planner', pay_frequency: 'semimonthly', pay_period: 'YEAR', pay_rate: 86000, }, ], first_name: 'Lourdes', } ] } ``` the following headers will be sent with webhook requests: ``` x-affix-api-signature: ab8474e609db95d5df3adc39ea3add7a7544bd215c5c520a30a650ae93a2fba7 x-affix-api-origin: webhooks-employees-webhook user-agent: affixapi.com ``` Before trusting the payload, you should sign the payload and verify the signature matches the signature sent by the `affixapi.com` service. This secures that the data sent to your `webhook_uri` is from the `affixapi.com` server. The signature is created by combining the signing secret (your `client_secret`) with the body of the request sent using a standard HMAC-SHA256 keyed hash. The signature can be created via: - create an `HMAC` with your `client_secret` - update the `HMAC` with the payload - get the hex digest -> this is the signature Sample `typescript` code that follows this recipe: ``` import { createHmac } from 'crypto'; export const computeSignature = ({ str, signingSecret, }: { signingSecret: string; str: string; }): string => { const hmac = createHmac('sha256', signingSecret); hmac.update(str); const signature = hmac.digest('hex'); return signature; }; ``` ## Rate limits Open endpoints (not gated by an API key) (applied at endpoint level): - 15 requests every 1 minute (by IP address) - 25 requests every 5 minutes (by IP address) Gated endpoints (require an API key) (applied at endpoint level): - 40 requests every 1 minute (by IP address) - 40 requests every 5 minutes (by `client_id`) Things to keep in mind: - Open endpoints (not gated by an API key) will likely be called by your users, not you, so rate limits generally would not apply to you. - As a developer, rate limits are applied at the endpoint granularity. - For example, say the rate limits below are 10 requests per minute by ip. from that same ip, within 1 minute, you get: - 10 requests per minute on `/orders`, - another 10 requests per minute on `/items`, - and another 10 requests per minute on `/identity`, - for a total of 30 requests per minute.
# Rake::ToolkitProgram Create toolkit programs easily with `Rake` and `OptionParser` syntax. Bash completions and usage help are baked in. ## Installation Add this line to your application's Gemfile: ```ruby gem 'rake-toolkit_program' ``` And then execute: $ bundle Or install it yourself as: $ gem install rake-toolkit_program ## Quickstart * Shebang it up (in a file named `awesome_tool.rb`) ```ruby #!/usr/bin/env ruby ``` * Require the library ```ruby require 'rake/toolkit_program' ``` * Make your life easier ```ruby Program = Rake::ToolkitProgram ``` * Define your command tasks ```ruby Program.command_tasks do desc "Build it" task 'build' do # Ruby code here end desc "Test it" task 'test' => ['build'] do # Rake syntax ↑↑↑↑↑↑↑ for dependencies # Ruby code here end end ``` You can use `Program.args` in your tasks to access the other arguments on the command line. For argument parsing integrated into the help provided by the program, see the use of `Rake::Task(Rake::ToolkitProgram::TaskExt)#parse_args` below. * Wire the mainline ```ruby Program.run(on_error: :exit_program!) if $0 == __FILE__ ``` * In the shell, prepare to run the program (UNIX/Linux systems only) ```console $ chmod +x awesome_tool.rb $ ./awesome_tool.rb --install-completions Completions installed in /home/rtweeks/.bashrc Source /home/rtweeks/.bash-complete/awesome_tool.rb-completions for immediate availability. $ source /home/rtweeks/.bash-complete/awesome_tool.rb-completions ``` * Ask for help ```console $ ./awesome_tool.rb help *** ./awesome_tool.rb Toolkit Program *** . . . ``` ## Usage Let's look at a short sample toolkit program -- put this in `awesome.rb`: ```ruby #!/usr/bin/env ruby require 'rake/toolkit_program' require 'ostruct' ToolkitProgram = Rake::ToolkitProgram ToolkitProgram.title = "My Awesome Toolkit of Awesome" ToolkitProgram.command_tasks do desc <<-END_DESC.dedent Fooing myself I'm not sure what I'm doing, but I'm definitely fooing! END_DESC task :foo do a = ToolkitProgram.args puts "I'm fooed#{' on a ' if a.implement}#{a.implement}" end.parse_args(into: OpenStruct.new) do |parser, args| parser.no_positional_args! parser.on('-i', '--implement IMPLEMENT', 'An implement on which to be fooed') do |val| args.implement = val end end end if __FILE__ == $0 ToolkitProgram.run(on_error: :exit_program!) end ``` Make sure to `chmod +x awesome.rb`! What does this support? $ ./awesome.rb foo I'm fooed $ ./awesome.rb --help *** My Awesome Toolkit of Awesome *** Usage: ./awesome.rb COMMAND [OPTION ...] Avaliable options vary depending on the command given. For details of a particular command, use: ./awesome.rb help COMMAND Commands: foo Fooing myself help Show a list of commands or details of one command Use help COMMAND to get more help on a specific command. $ ./awesome.rb help foo *** My Awesome Toolkit of Awesome *** Usage: ./awesome.rb foo [OPTION ...] Fooing myself I'm not sure what I'm doing, but I'm definitely fooing! Options: -i, --implement IMPLEMENT An implement on which to be fooed $ ./awesome.rb --install-completions Completions installed in /home/rtweeks/.bashrc Source /home/rtweeks/.bash-complete/awesome.rb-completions for immediate availability. $ source /home/rtweeks/.bash-complete/awesome.rb-completions $ ./awesome.rb <tab><tab> foo help $ ./awesome.rb f<tab> ↳ ./awesome.rb foo $ ./awesome.rb foo <tab> ↳ ./awesome.rb foo -- $ ./awesome.rb foo --<tab><tab> --help --implement $ ./awesome.rb foo --i<tab> ↳ ./awesome.rb foo --implement $ ./awesome.rb foo --implement <tab><tab> --help awesome.rb $ ./awesome.rb foo --implement spoon I'm fooed on a spoon ### Defining Toolkit Commands Just define tasks in the block of `Rake::ToolkitProgram.command_tasks` with `task` (i.e. `Rake::DSL#task`). If `desc` is used to provide a description, the task will become visible in help and completions. When a command task is initially defined, positional arguments to the command are available as an `Array` through `Rake::ToolkitProgram.args`. ### Option Parsing This gem extends `Rake::Task` with a `#parse_args` method that creates a `Rake::ToolkitProgram::CommandOptionParser` (derived from the standard library's `OptionParser`) and an argument accumulator and `yield`s them to its block. * The arguments accumulated through the `Rake::ToolkitProgram::CommandOptionParser` are available to the task in `Rake::ToolkitProgram.args`, replacing the normal `Array` of positional arguments. * Use the `into:` keyword of `#parse_args` to provide a custom argument accumulator object for the associated command. The default argument accumulator constructor can be defined with `Rake::ToolkitProgram.default_parsed_args`. Without either of these, the default accumulator is a `Hash`. * Options defined using `OptionParser#on` (or any of the variants) will print in the help for the associated command. ### Positional Arguments Accessing positional arguments given after the command name depends on whether or not `Rake::Task(Rake::ToolkitProgram::TaskExt)#parse_args` has been called on the command task. If this method is not called, positional arguments will be an `Array` accessible through `Rake::ToolkitProgram.args`. When `Rake::Task(Rake::ToolkitProgram::TaskExt)#parse_args` is used: * `Rake::ToolkitProgram::CommandOptionParser#capture_positionals` can be used to define how positional arguments are accumulated. * If the argument accumulator is a `Hash`, the default (without calling this method) is to assign the `Array` of positional arguments to the `nil` key of the `Hash`. * For other types of accumulators, the positional arguments are only accessible if `Rake::ToolkitProgram::CommandOptionParser#capture_positionals` is used to define how they are captured. * If a block is given to this method, the block of the method will receive the `Array` of positional arguments. If it is passed an argument value, that value is used as the key under which to store the positional arguments if the argument accumulator is a `Hash`. * `Rake::ToolkitProgram::CommandOptionParser#expect_positional_cardinality` can be used to set a rule for the count of positional arguments. This will affect the _usage_ presented in the help for the associated command. * `Rake::ToolkitProgram::CommandOptionParser#map_positional_args` may be used to transform (or otherwise process) positional arguments one at a time and in the context of options and/or arguments appearing earlier on the command line. ### Convenience Methods * `Rake::Task(Rake::ToolkitProgram::TaskExt)#prohibit_args` is a quick way, for commands that accept no options or positional arguments, to declare this so the help and bash completions reflect this. It is equivalent to using `#parse_args` and telling the parser `parser.expect_positional_cardinality(0)`. * `Rake::ToolkitProgram::CommandOptionParser#no_positional_args!` is a shortcut for calling `#expect_positional_cardinality(0)` on the same object. * `Rake::Task(Rake::ToolkitProgram::TaskExt)#invalid_args!` and `Rake::ToolkitProgram::CommandOptionParser#invalid_args!` are convenient ways to raise `Rake::ToolkitProgram::InvalidCommandLine` with a message. ## OptionParser in Rubies Before and After v2.4 The `OptionParser` class was extended in Ruby 2.4 to simplify capturing options into a `Hash` or other container implementing `#[]=` in a similar way. This gem supports that, but it means that behavior varies somewhat between the pre-2.4 era and the 2.4+ era. To have consistent behavior across that version change, the recommendation is to use a `Struct`, `OpenStruct`, or custom class to hold program options rather than `Hash`. ## Development After checking out the repo, run `bin/setup` to install dependencies. 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). To run the tests, use `rake`, `rake test`, or `rspec spec`. Tests can only be run on systems that support `Kernel#fork`, as this is used to present a pristine and isolated environment for setting up the tool. If run using Ruby 2.3 or earlier, some tests will be pending because functionality expects Ruby 2.4's `OptionParser`. ## Contributing Bug reports and pull requests are welcome on GitHub at https://github.com/PayTrace/rake-toolkit_program.
