发行说明

本次更新主要添加了对 Linux 的帧缓存(FrameBuffer)的支持,在没有 Xwindow 服务支持的字符终端模式下,LCUI 会改用 Linux 的帧缓存来输出图形内容,并直接从鼠标设备(/dev/input/mice)和标准输入(stdin)中读取用户输入。不过,这些支持并不完善,而作者也没有打算继续完善这块功能,理由很简单:没什么用,懒得浪费时间。如果你有丰富的 Linux 开发经验,可以向此项目提供改进方案,与其他人分享你的技术。

LCUI 的源代码中还有很多待改进的代码,包括:打算改、没时间改、懒得改和不想改的代码,其中有一部分代码已经用 FIXME 注释标记,这些注释中有的会说明为什么改进它,以及怎么改进它,如果你感兴趣,可以留意源代码中的 FIXME 注释内容,或者直接搜索 FIXME 注释,看看有哪些是可以帮上忙的。

如需了解更多代码变更细节,请查看此次拉取请求,包含 121 次提交,净增 3.8K 行代码。当前版本还存在已知且未修复的问题,你可以在问题列表里找到它们。

布局

居中和靠右是比较常用的对齐方式,比如对话框中的按钮组:

lcui-modal

之前版本中如果要实现这种效果,需要修改定位方式和右间距:position: absolute; right: 0;,一个按钮还好,多个按钮就得靠包装一个容器来定位,而且父级元素的宽高不会被撑开,始终为 0。为此,添加了简单的弹性(flex)布局支持,配合 justify-content 属性可以设置子级元素的对齐方式。justify-content 属性值有三种:flex-start、center 和 flex-end,效果是将每一行元素向左对齐、居中对齐、向右对齐。

lcui-flex-layout

字体

之前的版本只能根据字族(font-family)名称选择一种字体,即使这个字族包含不同粗细程度、风格的字体也只会选择常规(Regular)字体,连给界面中的标题加粗都很麻烦。为此,改进了字体数据的存储和操作方式,添加支持按字重(font-weight)和风格(font-style)选择字体,CSS 解析器也添加了相关的解析支持。

由于大多数字体都不会包含所有粗细程度和风格的字形,所以会存在找不到的情况,而本次更新的版本只是改进了存储和访问方式,并未实现字形自动加粗和倾斜功能,为解决这个问题就添加了一个回退机制,回退机制的设计参考自 MDN 文档,如需了解具体规则可查看此文档内容。

文本渲染

既然字体已经支持使用粗体和斜体,那么文本层(TextLayer)也就顺势加上了 [i][b] 标签的支持,方便测试字体效果。有了 color、i、b 这几个标签,界面中的代码块也就能加点特效:

lcui-code-highlight

考虑到文本中会引用命令行和代码,为了凸显这些文本,需要能够设置背景色,于是就添加了 [bgcolor] 标签支持,比如内容为 [bgcolor=#ddeeff]make install[bgcolor] 的文本,渲染效果会是这样:

lcui-text-bgcolor

对于英文文本,如果在换行时直接截断单词则会影响阅读体验,需要将溢出的单词整个换到下一行显示,控制这个规则的属性是 word-break,默认值为 normal,不中断单词,当值为 break-all 时会在任意字符间断行。

lcui-text-word-break

CSS

一篇文档会需要用到各种字体来提升阅读体验,比如:等宽字体、中文字体、西文字体,用 LCUI 呈现这样的文档的话会有些麻烦,需要手动在 XML 或 C 代码中引入这些字体文件,而作者在为 LCUI 开发 CSS 组件库时也遇到同样的问题,如果能在 CSS 中预先定义好各种字体的信息就能够省去这些麻烦。

CSS 标准中的 @font-face 规则可以解决这个问题,于是 LCUI 就增加了对 @font-face 规则的解析支持,方便通过 CSS 代码来控制加载哪些字体。@font-face 能够定义包括字族、风格、粗细程度、文件路径等在内的字体信息,然而这些属性中只有文件路径有用,在解析完规则后会直接加载该文件路径里的字体文件,因为 LCUI 的字体管理还不支持预先声明字体信息和按需加载字体文件这两个功能。

部件

添加了锚点(Anchor)部件,功能与 HTML 中的 <a> 元素类似,支持 href、target、key 属性,当该部件被点击后会判断 href 内容,如果是 https://http://file: 类型的链接,则调用系统默认的打开方式打开它;如果是普通的文件路径则会将之视为 xml 文件载入它,载入成功后会将新元素追加至 target 指定的 id 的元素内。简而言之,可以靠该部件实现“点击按钮切换界面”的功能。

lcui-anchor-widget

版本迭代

代码库的 Git 提交信息格式已经采用 Angular 提交信息规范 进行规范,方便为以后的版本收集改动内容。

版本号一直停留在 1.0.0 会浪费版本号的价值,但到目前为止,LCUI 内部函数命名还不够稳定,在后续版本更新中有可能会更名和移除,如果你有丰富的接口命名和模块化设计经验,可以向 LCUI 提交你的改进方案,以让 LCUI 尽早发布 1.0.0 版本。
