Question

我已启用默认＆＃34; log＆＃34; VS Code中的代码片段。我还添加了另一个片段。我输入前缀时都不显示。我已将editor.tabCompletion设置为true。

知道为什么这些不起作用？

Answer 1

有几种方法可以解决这个问题。问题是Intellisense正在阻碍或默认将您的片段放在列表的底部。

首先我使用了建议延迟，但后来我决定让Intellisense将我的代码段放在使用snippetSuggestions用户首选项的建议列表的顶部：

{
  "editor.tabCompletion": true,
  "editor.snippetSuggestions": "top"
}

Answer 2

有时候，首先被忽视的显而易见的东西。在启动VSCode并创建新文档（Ctrl + N）时，这些片段不起作用可能会令人惊讶。默认情况下，检查VSCode编辑器的右下角，将显示“纯文本”文件。使用摘要将文件类型更改为您喜欢的语言。

这可以克服一些不必要的麻烦；-）

Answer 3

如果您尝试插入PHP代码段，值得注意的是您必须手动包含

<?php

在片段开始工作之前。

Answer 4

我实际发现的是，当你拥有一个php intelliSense并且你想要一个 php 标签标签来打开和关闭时，我也将扩展名添加到一个html文件类型中。

   {
      "Open php tag": {
         "scope": "php, html",
         "prefix": "php",
         "body": [
           "<?php",
             "  $1",
           "?>"
        ],
        "description": "Opens php tags"
      }
   }

这对我有用：）

Answer 5

打开一个常见的html文件。
在右下角使用插件（例如：Django HTML），然后单击它
vscode顶部将打开一个窗口
单击“为...配置文件关联。'html'...”
搜索“ HTML”（需要使用大写锁定）
选择第一个选项

Answer 6

要与打字稿反应，我必须在范围内专门添加“ typescriptreact”。

 "scope": "javascript, typescript, typescriptreact"

Answer 7

选择范围时，扩展很重要。我最近已从使用.js扩展名进行反应，改为使用.tsx扩展名来进行打字稿反应。我的代码段说“ javascript，打字稿”，所以我以为我被覆盖了，但是tsx文件实际上被认为是“ typescriptreact”。我更改为以下内容，它开始在我的tsx文件上起作用：

{   
    "Styled Component React Arrow Function With Default Export": {
    "scope": "javascript, javascriptreact, typescript, typescriptreact",
    "prefix": "scraf",
    "body": [
        "import React from 'react'",
        "import styled from 'styled-components/macro'",
        "",
        "const Container = styled.div`",
        "  display: flex;",
        "`",
        "",
        "const ${TM_FILENAME_BASE} = () => {",
        "  return (",
        "    <Container>",
        "     $1",
        "    </Container>",
        "  )",
        "}",
        "export default ${TM_FILENAME_BASE}",
    ],
    "description": "Styled Component React Arrow Function With Default Export"
}

Answer 8

对于那些正在寻找覆盖默认代码段（日志）的用户

在用户摘录（至少对于打字稿）中，覆盖log.json文件摘录对我不起作用。

解决方案： 我创建了一个新的全局代码段（“文件”>“首选项”>“用户代码段”>“新的全局代码段”文件），并使用了不同的名称“ clog”（全名：“ clog.code-snippets”）和前缀。

Answer 9

当我创建第一个代码段时，我也遇到了这个问题。我添加了片段，没有任何反应。

重新启动VS Code并开始工作。

Answer 10

我的问题是某些片段有效，而其他片段则不然。 （例如：JavaScript Snippets效果很好）

当我安装了一个添加了相应的特定文件类型关联的插件（我的情况：* .blade.php）时，我的问题就解决了

在blade.json上创建UserSnippets时，它工作正常。

检查文件扩展名，看看是否有适合您文件类型的插件。
安装并尝试重新添加代码段。

Answer 11

我试图设置一个片段来自动将php打开和关闭标签添加到我的文件中，因为Robert Cooper注意到它只在我已经在代码特定类型块内写入时才起作用。

每当我在HTML块中使用它时，我都会!p加载<?php$1?>。该片段已设置为html.json文件。

Answer 12

只需重新启动VScode 。没关系。

Answer 13

此问题的原因是另一种语言在 VS Code 中处于活动状态。检查左下角 VS Code 将语言更改为所需的语言。截图如下。 enter image description here

点击C++，顶部会出现一个输入框。输入适当的语言，例如 HTML，问题将得到解决。

Answer 15

我不得不：

转到设置（Windows/Linux：文件>首选项>设置，macOS：代码>首选项>设置）并输入快速< /em> 在搜索框中，然后单击在 settings.json 中编辑：

添加

"editor.quickSuggestions": true

在相应的部分下文件类型（在我的情况下markdown）：

Answer 16

万一其他人遇到此问题，我正在使用本机响应，而我的JavaScript代码段则无法使用。我通过转到设置来检查settings.json，搜索快速建议，然后在settings.json中进行编辑。

False

否则，您可以为javascriptreact创建代码段。

Answer 17

对于面对此问题的其他任何人，请确保还检查摘要中定义的范围。尽管文件类型匹配，但片段没有显示给我，从范围内删除语言对我来说解决了这个问题。

Answer 18

从vscode扩展市场安装CodeLLDB平台软件包。应该可以解决您的问题

Answer 19

将"editor.tabCompletion":"on"更改为Part_No对我有用。

Answer 20

不要忘记在全局代码段中指定语言。就我而言，它已修复。

@ContextConfiguration(classes = ExecutableMain.class, initializers = ConfigFileApplicationContextInitializer.class)

Answer 21

在我的情况下，由于代码段名称中有一个空格，因此无法正常工作

{
  ...,
  "snippet name": { // it should be snippet_name. Notice the _
    ...
  }
}

因此请确保：

您在{name}.code-snippets文件夹下有一个.vscode文件
您的代码段名称不包含spaces
您将语言包括在范围内。我必须同时添加typescript和typescriptreact。

Visual Studio代码用户代码段不起作用
