\u0130lk Ruby Program\u0131n\u0131z\u0131 Nas\u0131l Yazars\u0131n\u0131z?<\/h2>\n

Ruby, zarif s\u00f6zdizimi ve geli\u015ftirici verimlili\u011fini \u00f6n planda tutan a\u00e7\u0131k kaynakl\u0131, dinamik bir programlama dilidir. Japon bilgisayar bilimcisi Yukihiro “Matz” Matsumoto taraf\u0131ndan 1990’lar\u0131n ortalar\u0131nda tasarlanan Ruby, “geli\u015ftiricinin en iyi arkada\u015f\u0131” olma felsefesiyle yola \u00e7\u0131km\u0131\u015ft\u0131r. Python ve Perl gibi dillerden ilham alarak, g\u00fc\u00e7l\u00fc bir nesne y\u00f6nelimli yap\u0131ya sahip, okunabilir ve do\u011fal bir dil yaratma amac\u0131 g\u00fcd\u00fclm\u00fc\u015ft\u00fcr. Bu makalede, Ruby’nin temellerini atacak, kurulumdan ba\u015flayarak ilk Ruby program\u0131n\u0131z\u0131 yazma s\u00fcrecini ad\u0131m ad\u0131m ke\u015ffedece\u011fiz. E\u011fer programlamaya yeni ba\u015fl\u0131yor veya farkl\u0131 bir dilden Ruby’ye ge\u00e7i\u015f yap\u0131yorsan\u0131z, bu rehber size sa\u011flam bir ba\u015flang\u0131\u00e7 noktas\u0131 sunacakt\u0131r.<\/p>\n

Ruby’nin pop\u00fclaritesi, \u00f6zellikle web geli\u015ftirme \u00e7er\u00e7evesi Ruby on Rails sayesinde b\u00fcy\u00fck \u00f6l\u00e7\u00fcde artm\u0131\u015ft\u0131r. Ancak Ruby’nin kullan\u0131m alanlar\u0131 sadece web ile s\u0131n\u0131rl\u0131 de\u011fildir; komut dosyalar\u0131, veri analizi, otomasyon ve hatta oyun geli\u015ftirme gibi bir\u00e7ok farkl\u0131 alanda da kendine yer bulur. Bu \u00e7ok y\u00f6nl\u00fcl\u00fck, Ruby’yi \u00f6\u011frenmeye de\u011fer k\u0131lan \u00f6nemli \u00f6zelliklerden biridir.<\/p>\n

Bu makalede, Ruby’yi bilgisayar\u0131n\u0131za nas\u0131l kuraca\u011f\u0131n\u0131z\u0131, temel s\u00f6zdizimi kurallar\u0131n\u0131, de\u011fi\u015fkenleri, veri tiplerini, kontrol ak\u0131\u015f\u0131n\u0131 ve metotlar\u0131 ele alaca\u011f\u0131z. Ard\u0131ndan, basit “Merhaba D\u00fcnya” program\u0131ndan ba\u015flayarak, kullan\u0131c\u0131 etkile\u015fimli ve daha karma\u015f\u0131k programlar yazma prati\u011fi yapaca\u011f\u0131z. Son olarak, yazd\u0131\u011f\u0131n\u0131z programlar\u0131 nas\u0131l \u00e7al\u0131\u015ft\u0131raca\u011f\u0131n\u0131z\u0131 ve olas\u0131 hatalarla nas\u0131l ba\u015fa \u00e7\u0131kaca\u011f\u0131n\u0131z\u0131 \u00f6\u011frenecek, Ruby yolculu\u011funuzda size rehberlik edecek sonraki ad\u0131mlar\u0131 tart\u0131\u015faca\u011f\u0131z.<\/p>\n

Ruby’yi Ortam\u0131n\u0131za Kurma<\/h3>\n

Ruby ile programlamaya ba\u015flamadan \u00f6nce, Ruby yorumlay\u0131c\u0131s\u0131n\u0131 bilgisayar\u0131n\u0131za kurman\u0131z gerekir. Kurulum s\u00fcreci, kulland\u0131\u011f\u0131n\u0131z i\u015fletim sistemine g\u00f6re de\u011fi\u015fiklik g\u00f6sterebilir.<\/p>\n

\u0130\u015fletim Sisteminize G\u00f6re Kurulum<\/h4>\n

Ruby kurulumu i\u00e7in birden fazla y\u00f6ntem bulunmaktad\u0131r. En yayg\u0131n ve \u00f6nerilen y\u00f6ntemleri a\u015fa\u011f\u0131da bulabilirsiniz.<\/p>\n

Windows<\/h5>\n

Windows kullan\u0131c\u0131lar\u0131 i\u00e7in en kolay ve \u00f6nerilen y\u00f6ntem RubyInstaller kullanmakt\u0131r.<\/p>\n

1. RubyInstaller \u0130ndirme<\/strong>: RubyInstaller web sitesine (rubyinstaller.org) gidin. “With Devkit” s\u00fcr\u00fcm\u00fcn\u00fc indirmeniz \u00f6nerilir. Devkit, Ruby gem’lerinin (paketlerinin) C veya C++ uzant\u0131lar\u0131 gerektirenlerini derlemek i\u00e7in gerekli ara\u00e7lar\u0131 i\u00e7erir.
\n2. Kurulum Sihirbaz\u0131<\/strong>: \u0130ndirdi\u011finiz .exe<\/code> dosyas\u0131n\u0131 \u00e7al\u0131\u015ft\u0131r\u0131n. Kurulum sihirbaz\u0131ndaki talimatlar\u0131 takip edin.
\n * Lisans s\u00f6zle\u015fmesini kabul edin.
\n * Kurulum konumunu se\u00e7in (varsay\u0131lan genellikle iyidir).
\n * \u00d6nemli: “Add Ruby executables to your PATH” (Ruby \u00e7al\u0131\u015ft\u0131r\u0131labilir dosyalar\u0131n\u0131 PATH’inize ekle) se\u00e7ene\u011fini i\u015faretledi\u011finizden emin olun. Bu, komut istemcisinden Ruby komutlar\u0131n\u0131 \u00e7al\u0131\u015ft\u0131rman\u0131za olanak tan\u0131r.
\n * Kurulum tamamland\u0131ktan sonra, Devkit kurulumu i\u00e7in bir se\u00e7enek sunulabilir. E\u011fer sunulursa, bunu da tamamlay\u0131n. Genellikle, komut istemcisinde ridk install<\/code> komutunu \u00e7al\u0131\u015ft\u0131rman\u0131z istenir. Bu komut, Devkit bile\u015fenlerini kurar.
\n3. Do\u011frulama<\/strong>: Komut istemcisini (Command Prompt veya PowerShell) a\u00e7\u0131n ve a\u015fa\u011f\u0131daki komutlar\u0131 \u00e7al\u0131\u015ft\u0131rarak Ruby’nin ba\u015far\u0131yla kuruldu\u011funu do\u011frulay\u0131n:<\/p>\n

    ruby -v<\/code> size kurulu Ruby s\u00fcr\u00fcm\u00fcn\u00fc g\u00f6stermelidir. irb<\/code> (Interactive Ruby) ise Ruby’nin etkile\u015fimli konsolunu ba\u015flatacakt\u0131r. exit<\/code> yaz\u0131p Enter tu\u015funa basarak irb<\/code>‘den \u00e7\u0131kabilirsiniz.<\/p>\n
macOS<\/h5>\n
macOS sistemlerinde genellikle \u00f6nceden y\u00fcklenmi\u015f bir Ruby s\u00fcr\u00fcm\u00fc bulunur. Ancak bu s\u00fcr\u00fcm genellikle eski olabilir ve sistem taraf\u0131ndan kullan\u0131ld\u0131\u011f\u0131 i\u00e7in g\u00fcncellemeleri veya de\u011fi\u015fiklikleri riskli olabilir. Bu nedenle, Ruby s\u00fcr\u00fcm y\u00f6neticileri (rbenv veya RVM) kullanmak \u015fiddetle tavsiye edilir. Bu y\u00f6neticiler, farkl\u0131 Ruby s\u00fcr\u00fcmlerini kolayca kurman\u0131za ve projeleriniz aras\u0131nda ge\u00e7i\u015f yapman\u0131za olanak tan\u0131r.<\/p>\n

\n3.  rbenv’i PATH’e Ekleme<\/strong>: rbenv<\/code>‘i kabu\u011funuza (shell) eklemeniz gerekir. Genellikle .zshrc<\/code> (macOS Catalina ve sonras\u0131) veya .bash_profile<\/code> dosyan\u0131za a\u015fa\u011f\u0131daki sat\u0131rlar\u0131 eklemeniz gerekir:<\/p>\n

Komut Sat\u0131r\u0131ndan \u00c7al\u0131\u015ft\u0131rma<\/h4>\n
Ruby programlar\u0131n\u0131z\u0131 \u00e7al\u0131\u015ft\u0131rmak i\u00e7in temel komut ruby [dosya_ad\u0131.rb]<\/code> \u015feklindedir.<\/p>\n
*   Ayn\u0131 Dizin<\/strong>: E\u011fer terminaliniz, Ruby dosyan\u0131zla ayn\u0131 dizindeyse, do\u011frudan ruby dosya_ad\u0131.rb<\/code> yazman\u0131z yeterlidir.

Programlamaya yeni ba\u015flayanlar i\u00e7in hatalar ka\u00e7\u0131n\u0131lmazd\u0131r. \u00d6nemli olan, hata mesajlar\u0131n\u0131 okumay\u0131 ve anlamay\u0131 \u00f6\u011frenmektir.<\/p>\n
*   SyntaxError<\/code><\/strong>: S\u00f6zdizimi hatas\u0131 demektir.
