文本编辑器（或称文字编辑器）是用作编写普通文字的应用软件，它与文档编辑器（或称文字处理器）不同之处在于它并非用作桌面排版（例如文档格式处理），它常用来编写程序的源代码。(A text editor (or text editor) is used as the application software is written in ordinary text, and document editor (or word processor) the difference is that it is not used as a desktop publishing (e.g. document format processing), it is often used to write the program source code.)
