Getting Visual Studio Code to (auto-)format R-Code

Question

Working on Windows 10, no Formatter for the R-Language seems to do its job in Visual Studio Code. I've tried R support for Visual Studio Code and R-Tools, which seem to be the most popular extensions out there.

I've also checked that the path to the R binary file is correct. Nevertheless, when I hit SHIFT + ALT + F I get the "There is no formatter for 'r'-files installed." message.

Moreover I tried to enable the Settings Editor: Format On Type and Editor: Format On Save, but without luck.

Haven't been able to find other posts about this problem online. Any ideas? Big thanks

Answer 1

Installing R Language Server and R LSP Client should do what you want

1. Open R Studio and install languageserver, tying this in the console window: install.packages("languageserver")

2. Install R LSP Client Extension in VS Code

3. Toggle Format on Type, Format On Save, and Format On Paste settings in VS Code editor preferences, depending on your needs.

Answer 2

Answer works as per user3451039, but if you are using another formatter in editor.defaultFormatter (such as Prettier), you may need to add the following to your settings.json in VSCode:

  "[r]": {
    "editor.defaultFormatter": "REditorSupport.r-lsp"
  },

Answer 3

Adding to Ctrl-Zed answer, if you have VSCode R extension by Yuki Ueda, this worked for me:

"[r]": {
    "editor.defaultFormatter": "Ikuyadeu.r"
  },
