http://github.com/sparkboxx/csv_importer Ever needed to import csv files where every row needs to be converted into a model? The CSV importer turns every row of a CSV file into an object. Each column is matched and tested against a given class. You can provide a dictionary with translations between the CSV column names and the object properties.
csv, one of the standard libraries, in Ruby 2.6 has many improvements: * Default gemified * Faster CSV parsing * Faster CSV writing * Clean new CSV parser implementation for further improvements * Reconstructed test suites for further improvements * Benchmark suites for further performance improvements These improvements are done without breaking backward compatibility. This talk describes details of these improvements by a new csv maintainer.

This RubyGem contains a nice-n-easy funding projects simulation, called FundList. The sim runs in command-line, calling just the command crowd_fund (easy as that :0 ) You can choose the number of funding rounds and it will display the current stats of the projects. You can also create a '.csv' file to hold projects, with a current amount and a target. This file should be put next to the command when calling the sim. File structure: --NAME--|--TARGET--|--AMOUNT-- (This is just for explanatory purpose) Project,1000,100 (The commas must be put into each string of projects, without blankspace.) Have fun on this simulation. If you have any ideas, you can use the code, which already is tested, to create a new, different, sim! Good-bye !! =)
This RubyGem contais a nice and fun game called Knucleheads (once using the code in your computer, you can call it anything! :) ) The game runs into the command-line, using just the command 'studio_game'. You can choose the number of rounds you want to play and, when exiting, you'll receive the stats of the rounds. You can create a '.csv' file to push new player into the game. The file must have the following structure: ---NAME----|---HEALTH--- (This is just explanatory, not to put into file) Player-name,100 (The comma should appear into each string.) Well what else can I say? Just...have fun, playing and using this humble code into your robust and well-tested program. Good-bye !!!
# StudioGame (Alec) Jogo de terminal em Ruby com **jogadores, dados, tesouros e variações de jogadores** (Clumsy e Berserk), empacotado como gem. > Nome do gem (exemplo): `studio_game_alec` --- ## 🚀 Instalação e execução ### Rodando direto do código-fonte No diretório do projeto: ```bash ruby bin/studio_game ``` Se você não passar um arquivo de jogadores via CLI, o script usa o `players.csv` que fica em `bin/` por padrão. Também funciona passando um CSV na linha de comando: ```bash ruby bin/studio_game my_favorite_players.csv ``` ### Como gem (local) Empacote e instale localmente: ```bash gem build studio_game.gemspec gem install studio_game_alec-<versao>.gem ``` Depois rode: ```bash studio_game ``` > No Windows, o executável será resolvido pelo RubyGems. Se preferir, rode: `ruby bin/studio_game`. --- ## 📁 Estrutura do projeto ``` games/ ├─ bin/ │ ├─ studio_game # script principal (tem shebang) │ └─ players.csv # CSV padrão (nome,vida) ├─ lib/ │ └─ studio_game/ │ ├─ auditable.rb │ ├─ berserk_player.rb │ ├─ clumsy_player.rb │ ├─ die.rb │ ├─ game.rb │ ├─ game_turn.rb │ ├─ loaded_die.rb │ ├─ playable.rb │ ├─ player.rb │ └─ treasure_trove.rb ├─ spec/ │ └─ studio_game/ # specs RSpec ├─ LICENSE ├─ README.md └─ studio_game.gemspec ``` - **Namespace:** todo o código vive dentro do módulo `StudioGame` para evitar colisões. - **bin/studio_game:** script CLI com shebang (`#!/usr/bin/env ruby`). Faz _fallback_ do `$LOAD_PATH` para `lib` quando usado fora da gem. - **lib/studio_game/**: código da biblioteca (classes/módulos). - **spec/**: testes RSpec. --- ## 🧩 Conceitos principais - **Player** (`player.rb`): representa um jogador com `name`, `health`, coleta tesouros e calcula `score` (= `health` + `points`). Inclui o mixin **Playable**. - **Playable** (`playable.rb`): mixin com `w00t`, `blam` e `strong?` (altera/consulta `health` via getters/setters). - **TreasureTrove** (`treasure_trove.rb`): define `Treasure = Struct.new(:name,:points)` e a constante `TREASURES`; possui `.random`. - **Die/LoadedDie** (`die.rb`, `loaded_die.rb`): rolam valores (o carregado favorece 1,1,2,5,6,6). Ambos incluem **Auditable**. - **Auditable** (`auditable.rb`): imprime “Rolled a X (DieClass)” após cada rolagem. - **Game** (`game.rb`): agrega jogadores, carrega CSV, executa rodadas, soma pontos e salva _high scores_. - **GameTurn** (`game_turn.rb`): executa a lógica de um turno para um jogador (rola dado, aplica `blam/w00t/skip` e concede tesouro). - **ClumsyPlayer / BerserkPlayer**: variações de `Player` que modificam comportamento de `w00t` e de coleta de tesouros. --- ## 🧪 Testes Rode todos os testes: ```bash rspec ``` Principais coisas testadas: - Ordenação de jogadores por `score` (usa `<=>` em `Player`). - Cálculo de `points` e `score` (soma de tesouros + vida). - Efeitos de `w00t`/`blam` e força (`strong?`). - Lógica de turno com _stubs_ de dado (`allow_any_instance_of(LoadedDie).to receive(:roll).and_return(n)`). - Comportamentos de `ClumsyPlayer` e `BerserkPlayer`. --- ## 📦 CSVs e caminhos - `bin/studio_game` resolve o CSV padrão assim: ```ruby default_player_file = File.join(File.dirname(__FILE__), 'players.csv') game.load_players(ARGV.shift || default_player_file) ``` - Você pode passar um arquivo `.csv` via CLI como primeiro argumento. Formato do CSV: ``` Moe,100 Larry,60 Curly,125 ``` --- ## 🧾 High Scores Após sair do loop, o jogo grava `high_score.txt` com as entradas ordenadas. Cada linha é formatada por `Game#high_score_entry`: ``` <nome com padding de pontos> <score> ``` --- ## 🛠️ Dicas de desenvolvimento - Use `require 'studio_game/arquivo'` quando a gem estiver instalada. - No script binário, o `begin/rescue LoadError` faz _fallback_ para `$LOAD_PATH` local, útil fora da gem. - Para debugar I/O em testes, o spec redireciona `STDOUT` (`$stdout = StringIO.new`). --- ## 📚 Licença MIT – veja o arquivo `LICENSE`.
# Crowdfund (Alec) Ferramenta de linha de comando e biblioteca Ruby para simular um programa de **arrecadação de fundos** com rodadas, promessas (pledges) e diferentes tipos de projetos (básico, com *matching*, e *grant*). ## Instalação ```bash gem install crowdfund_alec ``` Ou rode a partir do código-fonte: ```bash ruby bin/crowdfund ``` ## Como funciona - Você carrega projetos via CSV (nome, fundos_iniciais, meta). - Em cada rodada, um dado é rolado para **adicionar** (+25) ou **remover** (–15) fundos do projeto. - Em paralelo, o projeto recebe **pledges** aleatórios: bronze ($50), silver ($75), gold ($100). - Projetos podem ter comportamento especial: - **MatchingProject**: quando chega a 50% da meta, cada `add_fund` passa a dobrar (+50). - **GrantProject**: nunca perde fundos em `remove_fund`. - Ao sair, o relatório salva os **subfinanciados** em `needmoremoney.txt` e imprime estatísticas. ## Uso (CLI) ```bash # (1) CSV padrão (bin/projects.csv) ruby bin/crowdfund # (2) Informando um CSV customizado ruby bin/crowdfund caminho/para/projetos.csv ``` Durante a execução: - Digite um número para a quantidade de rodadas. - Digite `q` ou `e` para sair e ver o relatório final. ### Formato do CSV ``` NomeDoProjeto,fundos_iniciais,meta BuyaBoat,5,10000 TraveltoVictoriaIsland,5,3000 GetaPuppy,5,300 ``` ## Saída esperada - Resumo por rodada dos fundos e pledges recebidos. - Arquivo `needmoremoney.txt` contendo: - Título do relatório. - Projetos totalmente financiados. - Projetos subfinanciados ordenados por **quanto falta**. - Snapshot CSV de todos os projetos. ## API (uso como biblioteca) Requerendo as classes principais: ```ruby require 'crowdfund/project' require 'crowdfund/fund_request' ``` Criando projetos e executando rodadas: ```ruby project = Project.new("My App", 500, 2000) funding = FundRequest.new("Startup do Alec") funding.add_project(project) funding.request_funding(5) funding.print_results ``` ### Classes principais - `Project` - Atributos: `name`, `fund_amount`, `target_fund_amount` - Métodos: `add_fund`, `remove_fund`, `funds_needed`, `funded?`, `received_pledge`, `pledges`, `total_funds`, `each_received_pledge`, `to_csv`, `status` - `FundRequest` - Gerencia lista de projetos, executa rodadas, imprime e salva relatórios. - `MatchingProject < Project` - Dobra `add_fund` quando `halfway_funded?` (>= 50% da meta). - `GrantProject < Project` - Sobrescreve `remove_fund` para nunca diminuir fundos. - `Pledgesmod` - Constante `PLEDGES` e `.random` para escolher bronze/silver/gold. - `FundingRound` - Regras de uma rodada: rola `Die`, aplica `add/remove`, atribui pledge. - `Fundable` (mixin) - Implementa `add_fund`, `remove_fund`, `funds_needed`, `funded?`. - `Die` - D6 simples com `roll`. ## Testes Rodar todos os testes: ```bash rspec ``` Principais cenários cobertos: - Regras de `add_fund`/`remove_fund`. - Comportamento de `MatchingProject` e `GrantProject`. - Integração de `FundingRound` e `Pledgesmod`. - Geração do relatório em `FundRequest`. ## Licença MIT — consulte o arquivo `LICENSE`.
