SynEdit/zh CN

发展历史

SynEdit 是一个开源的文本编辑器，支持多种语法高亮，官方网页在 SF.net，2007年发布版本 2.0.6，现已迁移到 github。

在 Lazarus 界面中，提供一个 SynEdit tab 组件面板。其中包含一个名为TSynEdit的源编辑器组件，支持几种语法高亮，和其他组件一起用于源代码的编辑。包含在Lazarus中的SynEdit是从 SynEdit 1.0.3 中分离出来的，大部分代码由 Martin Friebe 发表在论坛上，并且被改编和扩展了很多，在与原始SynEdit（MPL或GPL）相同的条款下获得许可。

原始版本 SynEdit 与 Lazarus版 SynEdit

Lazarus 版SynEdit 大部分是由 Martin Friebe. Martin 在论坛上写的，那么自从分支出现后，发生了什么呢？

加入Laza的大事记：

• 折叠(代码块)
• 可配置的天沟 - 天沟部分
• 几个编辑器之间的共享文本
• utf-8支持
• 同步编辑插件
• 基本的RTL-LTR支持
• 鼠标配置通过MouseActions
• 重写各种亮点

Delphi和Lazarus的两个版本，代码库是独立重构的，他们之间的重叠很少。

进一步的开发与讨论

• RTL (right-to-left): started by Mazen (partly implemented on Windows)
• SynEdit 只支持 UTF8; 不存在 ASCII/ANSI 版本。 A font is pre-selected depending on the system. The user can choose another font, but must then take care to choose a monospaced font.
  • automatic monospace font selection: At the moment SynEdit starts with a font 'courier'. At the moment the LCL TFont does not provide a property to filter monospaced fonts.
  • automatic UTF-8 font selection: Same as above monospace, but also with an UTF-8 font, so that for example umlauts are shown correctly.
• Dead keys. Most keyboards support typing two or more keys to create one special character (like accented or umlaut characters). (This is handled by LCL widgedset)
• Redesign of the SynEdit component. The primary goal is more reliable display and navigation in the text. A more modular approach also allows for better integration of extensions, and for specialized controls, for use outside of Lazarus.
• Word Wrapping. This is an experimental implementation following the idea of the TextTrimmer/TabExpansion classes. The linked bugtraker issue has the class and the explanation of changes required in other files for it to work.
• Hooks in SynEdit key/command processing. On the forum: http://forum.lazarus-ide.org/index.php/topic,35592.msg243316.html#msg243316
