Lazaurs編輯器是很強大的，支持代碼補全，自動完成，模板編輯，多行縮進注釋，選定代碼後批量更改裡面的單詞！
Lazarus 支持多種操作系統，Windows，以及幾種 Linux 發行版，當然包括Ubuntu 15.10，Mac OS X。各個Linux發行版安裝Lazarus都很方便。
用Lazarus 編寫IDE時會用到synedit 標簽中的控件來高亮顯示，是delphi的開源替代品.freepascal://wiki.lazarus。支持 FreeBSD.freepascal，另外可以下載lazarus 的源代碼來學習，利用 Lazarus 創建的應用程序，也能被容易地移植到多種操作系統上，特別是圖形界面應用程序。Lazarus 與 Delphi 高度兼容Lazarus 是基於 Free Pascal 的 Object Pascal 語言集成開發環境（IDE）。
下面我們來看看在Ubuntu 15.10下怎樣安裝最新的Lazarus IDE 1.6。
本文環境是32位Ubuntu 15.10，所以下載的是32位的Lazarus IDE 1.6。
