如何在 vscode 中为 R 的 magrittr 管道添加别名

Question

我想要一个用于在 VScode 中输入

%>%

（R 中的管道命令）的别名。在 RStudio 中，这被映射到 ctrl+shift+M，但如果由于任何原因这在 VSCode 中不可用，我很乐意映射到其他东西，我只是不确定如何添加新别名。

Answer 1

您只需将其添加到您的

keybindings.json

文件中（请参阅此处了解如何打开它）：

{
  "key": "Ctrl+Shift+m",
  "command": "type",
  "args": { "text": " %>% " },
  "when": "editorTextFocus && editorLangId == r"
}

这样你就不需要宏了

---

keybindings.json

修改后的文件：

// Place your key bindings in this file to override the defaults
[
    {
        "key": "Ctrl+Shift+m",
        "command": "type",
        "args": { "text": " %>% " },
        "when": "editorTextFocus && editorLangId == r"
    }
]

如果您是 Mac 用户并且更喜欢 RStudio 的

Cmd+Shift+m

快捷键，请将上面的关键行设置为

"key": "Cmd+Shift+m"

。

您也可以通过以下方式添加到rmd

{
  "key": "Ctrl+Shift+m",
  "command": "type",
  "args": { "text": " %>% " },
  "when": "editorTextFocus && editorLangId == rmd"
}

并按以下方式连接到R终端

    {
      "key": "Ctrl+Shift+m",
      "command": "workbench.action.terminal.sendSequence",
      "args": { "text": " %>% " },
      "when": "terminalFocus"
    },

这就是我的 settings.json 添加 %>% 和 <- to my Rmarkdowns, Rscripts and R terminal (including radian):

[
    // OTHER KEYBINDINGS,


 
    // keybindings for R scripts. 
    {
      "key": "Ctrl+Shift+m",
      "command": "type",
      "args": { "text": " %>% " },
      "when": "editorTextFocus && editorLangId == r"
    },
    {
      "key": "Alt+-",
      "command": "type",
      "args": { "text": " <- " },
      "when": "editorTextFocus && editorLangId == r"
    },
    // keybindings for Rmarkdown
    {
      "key": "Ctrl+Shift+m",
      "command": "type",
      "args": { "text": " %>% " },
      "when": "editorTextFocus && editorLangId == rmd"
    },
    {
      "key": "Alt+-",
      "command": "type",
      "args": { "text": " <- " },
      "when": "editorTextFocus && editorLangId == rmd"
    },
    // keybindings for R terminal (radian included)
    {
      "key": "Ctrl+Shift+m",
      "command": "workbench.action.terminal.sendSequence",
      "args": { "text": " %>% " },
      "when": "terminalFocus"
    },
    {
      "key": "Alt+-",
      "command": "workbench.action.terminal.sendSequence",
      "args": { "text": " <- " },
      "when": "terminalFocus"
    },
    // OTHER KEYBINDINGS

]

我不使用 vscode，但也许宏可以使用 https://marketplace.visualstudio.com/items?itemName=geddski.macros 工作。它在将参数传递给命令部分说：

许多命令接受参数，例如“type”命令，它允许您将文本插入编辑器。

也许这会起作用（未经测试）。将其添加到您的

settings.json

：

"macros": {
  "addPipe": [
    "cursorEnd",
      {"command": "type", "args": {"text": "%>%"}}
  ]
}

将此送给您的

keybindings.json

：

{
  "key": "ctrl+shift+M",
  "command": "macros.addPipe"
}
