Evet, askerliktir \u015fudur budur \u00e7ok zaman oldu. Askerde excel d\u0131\u015f\u0131nda kendimi pek geli\u015ftiremedim, o d\u00f6nemi bu kadar k\u0131sa bir \u00f6zetle ge\u00e7i\u015ftireyim \ud83d\ude42<\/p>\n

Ingenue nedir derseniz, tiyatro vb. de olan saf k\u0131z karakterlerine verilen isimmi\u015f. <\/p>\n

Ayn\u0131 zamanda yeni (ve \u00e7ok eski) projemin \u015fu anki kod ad\u0131 olarak se\u00e7tim, neden derseniz az \u00f6nce Atoms For Peace – Ingenue dinlemekte idim ve projenin geli\u015fme stili de oradaki dansa benzemekte.<\/p>\n

Kendisi bir programlama dili olmakta. Dynamic typing bir dil ve \u015fu anda bir interpreter \u00fczerinden \u00e7al\u0131\u015fmakta. Syntax olarak C ye baya bir benzer. “E neden yaz\u0131yorsun” derseniz \u00e7o\u011funlukla e\u011flence i\u00e7in. Ama dile yeni \u00f6zelliklerde getirmek istiyorum.<\/p>\n

Dedi\u011fim gibi, dil dynamic typing olmakta. T\u00fcm de\u011fi\u015fkenler operat\u00f6rlere g\u00f6re tiplerini de\u011fi\u015ftirebiliyor. mesele a = b + c;<\/code> gibi bir kodda a n\u0131n tip i b ve c ye g\u00f6re belirleniyor. \u015eu anl\u0131k 3 tip var, integer, float ve string. Ve bunlar\u0131n bask\u0131nl\u0131k s\u0131ras\u0131da integera = b * 2;<\/code> gibi bir program\u0131n sonraki bir a\u015famas\u0131nda bu 2 de\u011feri 3 olabilecek. Daha ilgin\u00e7 bir \u00f6rnek vermek gerekirse yine ayn\u0131 kodda * operat\u00f6r\u00fc de\u011fi\u015febilecek ya da assignment operat\u00f6r\u00fcn\u00fcn hedefi a de\u011fil de c olabilecek. Bir nevi hot swapping gibi. B\u00f6yle bir \u015feye izin veren diller var m\u0131 bilmiyorum ama fikir ilk kaynak kodunu de\u011fi\u015ftirmeye izin veren brainfuck interpreterlar\u0131 oldu\u011funu \u00f6\u011frendi\u011fimde akl\u0131ma gelmi\u015fti.<\/p>\n

Ne i\u015fe yarayacak derseniz emin de\u011filim \ud83d\ude42 ama farkl\u0131 bir programlama stili olacak diye umuyorum. <\/p>\n

Nas\u0131l \u00e7al\u0131\u015fmakta derseniz \u015fu anda 2 a\u015famadan olu\u015fuyor. Lexer\/parser k\u0131sm\u0131 ve interpreter k\u0131sm\u0131. Parsing a\u015famas\u0131nda kaynak kodunu al\u0131yorum ve token lar\u0131na ay\u0131r\u0131yorum, bu tokenlarda interpreter taraf\u0131ndan yorumlan\u0131yor ve kod \u00e7al\u0131\u015f\u0131yor. Mesela<\/p>\n

\r\na = 5;\r\nb = 3.0;\r\nc = a + b; \r\nd = a++; \r\nif(a > 0) { \r\n    d = a + b; \r\n} else d = 0;\r\n<\/pre>\n
gibi bir kod olsun. Parser bunu \u015f\u00f6yle bir \u015feye \u00e7eviriyor.<\/p>\n

Kodun parse edilmi\u015f hali de interpreter taraf\u0131ndan input olarak al\u0131n\u0131yor ve program olu\u015fturuluyor.
