Ahmad Ismail's questions

这是两个片段

"Remove leading whitespace": {
    "body": [
        "${TM_SELECTED_TEXT/^(\\s+)//gm}"
    ],
    "description": "Remove leading whitespace"
},

"Replace non-empty lines with 'xyz'": {
    "body": [
        "${TM_SELECTED_TEXT/^.+$/xyz/gm}"
    ],
    "description": "Replace non-empty lines with 'xyz'"
}

第一个删除前导空格（但也删除表情行），另一个将非空行替换为“xyz”。

我希望代码片段删除非空行的前导空格（保留非空行，如用“xyz”替换非空行中所示）。所以我想转换以下文本

Working towards

    long-term goals or aspirations



can provide motivation


        challenges and obstacles

到

Working towards

long-term goals or aspirations



can provide motivation


challenges and obstacles

我怎样才能做到这一点？

我有一个如下所示的 json：

[
  {
    "name": "architecture-design-detailed",
    "rootPath": "/media/ismail/architecture-design-detailed/_Working/_NotesFiltered/_software/architecture-design-detailed",
    "paths": [],
    "group": "",
    "enabled": true
  },
  {
    "name": "architecture-design-detailed-engineering",
    "rootPath": "/media/ismail/architecture-design-detailed/_Working/_NotesFiltered/_software/architecture-design-detailed-engineering",
    "paths": [],
    "group": "",
    "enabled": true
  }
]

如果名字是architecture-design-detailed,

• 将名称更改为new_name_here

• 用 new_name_here 替换 rootPath 的最后一部分（这是架构设计详细的，在最后一个 / 之后）。

所以预期的输出是：

[
  {
    "name": "new_name_here",
    "rootPath": "/media/ismail/architecture-design-detailed/_Working/_NotesFiltered/_software/new_name_here",
    "paths": [],
    "group": "",
    "enabled": true
  },
  {
    "name": "architecture-design-detailed-engineering",
    "rootPath": "/media/ismail/architecture-design-detailed/_Working/_NotesFiltered/_software/architecture-design-detailed-engineering",
    "paths": [],
    "group": "",
    "enabled": true
  }
]

到目前为止我想到的是：

jq 'map(if .name == "architecture-design-detailed" then .name = "new_name_here" else . end)'

但不明白如何替换 rootPath 的最后一部分。我认为我们必须使用subor gsub。但不明白如何。
