Bash脚本与regex查找/替换垂直对齐赋值操作符在文件中

Question

我有一个(翡翠模板)文件的集合，其属性如下所示:

a.btn(data-ng-class = "{true:'black', false:'blue'}[viewModel.currentDictionaryUid == '<%= full.uid %>']", href = "#<%= viewRoot %>/<%= full.uid %>")

我正在寻找一种快速的方法来转换它们看起来更像这样:

a.btn(data-ng-class = "{true:'black', false:'blue'}[viewModel.currentDictionaryUid == '<%= full.uid %>']"
      href          = "#<%= viewRoot %>/<%= full.uid %>")

所有以逗号分隔的属性现在都在单独的行上，键都从左边开始相同的x个字符，等号也都从左边开始相同的x个字符。

示例测试文件:

html
  body
    // HEADER GOES HERE
    .header.navbar.navbar-inverse.navbar-fixed-top(style = "z-index:1001;", data-ng-controller = "ControllerWidgetCoreHeader", data-ng-include = "'viewWidgetCoreHeader'")
    .page-container.row-fluid(data-ng-class = "{'sidebar-closed':sidebarClosed}")
      // LEFT MENU GOES HERE
      .page-sidebar.nav-collapse.collapse(data-ng-hide = "quizMode", data-ng-class = "{'in':topBarOpen}", style = "z-index:1000;", data-ng-controller = "ControllerWidgetCoreLeftMenu", data-ng-include = "'viewWidgetCoreLeftMenu'")
      .page-content(data-ng-class = "{'page-content-quiz-mode':quizMode}")
        // PAGE CONTENT GOES HERE
        .container-fluid(data-ng-controller = "ControllerCoreWidgets", data-ng-include = "'viewCoreWidgets'")
    .footer(data-ng-show = "false", data-ng-controller = "ControllerWidgetCoreFooter", data-ng-include = "'viewWidgetCoreFooter'")

错误:(Mac OSX 10.8.4)

Casey-Flynns-MacBook-Air:views casey$ sed -i'' 's@,s+([a-z]+)s+=@nt1 =@g' **/*.jade
sed: 1: "viewsDirectives/viewCol ...": invalid command code v

同样在单个文件上:

Casey-Flynns-MacBook-Air:views casey$ sed -i'' 's@,s+([a-z]+)s+=@nt1 =@g' viewCore.jade
sed: 1: "viewCore.jade": invalid command code v

Answer 1

试着这样做:

sed 's@,s+([a-z]+)s+=@nt1 =@g' **/*.jade

，如果它符合您的需要，您可以使用代替与-i开关:

sed -i 's@,s+([a-z]+)s+=@nt1 =@g' **/*.jade

和MacOsX版本(它以奇数方式处理-i开关):

sed -i'' 's@,s+([a-z]+)s+=@nt1 =@g' **/*.jade

Answer 2

不确定这是否有帮助，但你可以尝试这样做:

awk -v RS="," '{ print $0 }' file | column -t | awk '!/=/ {$1=$1}1'

测试:

$ cat file
html
  body
    // HEADER GOES HERE
    .header.navbar.navbar-inverse.navbar-fixed-top(style = "z-index:1001;", data-ng-controller = "ControllerWidgetCoreHeader", data-ng-include = "'viewWidgetCoreHeader'")
    .page-container.row-fluid(data-ng-class = "{'sidebar-closed':sidebarClosed}")
      // LEFT MENU GOES HERE
      .page-sidebar.nav-collapse.collapse(data-ng-hide = "quizMode", data-ng-class = "{'in':topBarOpen}", style = "z-index:1000;", data-ng-controller = "ControllerWidgetCoreLeftMenu", data-ng-include = "'viewWidgetCoreLeftMenu'")
      .page-content(data-ng-class = "{'page-content-quiz-mode':quizMode}")
        // PAGE CONTENT GOES HERE
        .container-fluid(data-ng-controller = "ControllerCoreWidgets", data-ng-include = "'viewCoreWidgets'")
    .footer(data-ng-show = "false", data-ng-controller = "ControllerWidgetCoreFooter", data-ng-include = "'viewWidgetCoreFooter'")
