我如何在 vscode 中从 R 中获得 magrittr 管道的别名

Question

我想要一个别名来输入%>%vscode（R 中的管道命令）。在 Rstudio 中，这被映射到 ctrl + shift + M，但如果由于任何原因在 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

也可以通过以下方式添加到rmd中

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

并通过以下方式连接到 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 <- 到我的 Rmarkdowns、Rscripts 和 R 终端（包括弧度）的方式：

[
    // 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

]

您只需要将此添加到您的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"
}

这样你就不需要宏

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"
    }
]
