VSTosc

Productivity shortcuts from ToSc, e.g.:

• goToAnything – Jump to UI areas or line:column instantly
• runCommand – Run shell input against the selection/stdin
• runSelection – Execute selection as shell script inline
• toggleEditorTerminalFocus – Smart editor/terminal toggle
• mathMode – Insert ~$$ and place cursor inside math mode
• knitRmd – Render current file via rmarkdown::render
• updateRDocstring – Generate roxygen2 docs for current R fn
• testRFunction – Run the matching testthat file/function

Installation

Open the Extensions Tab in VSCode's activity bar and search for vstosc. Then click install.

Usage

Hit F1 or Ctrl+Shift+P to open the Command Palette and then choose a command.

For often used commands you might want to define a shortcut as shown below:

Commands

runCommand

Opens an input box asking the user for a command. The entered command runs inside a configurable shell and the trimmed output is inserted at the current cursor position. If text is selected, it is passed as stdin to the command and replaced with the trimmed output.

The following settings can be used to customize the shell used for command execution:

• vstosc.shell.windows – default cmd.exe /q /c
• vstosc.shell.mac – default /bin/sh -e
• vstosc.shell.linux – default /bin/sh -e

Each command is written to a temporary file, which is then executed using the configured shell. When customizing the shell command, make sure it accepts the pattern <shell-command> <script-file>, where <script-file> is the temporary file created by the extension. For example, to run everything through Git Bash on Windows, set vstosc.shell.windows to "C:/Program Files/Git/bin/bash.exe" -lc.

runSelection

Executes the current selection using the same shell configuration described under runCommand (defaults: /bin/sh -e on macOS/Linux, cmd.exe /q /c on Windows) and replaces the selection with the trimmed command output.

updateRDocstring

Updates the roxygen2 docstring of the R function the cursor currently is in.

⚠️WARNING: This command requires the R package toscutil (version 2.7.1 or greater). For now you have to install it by hand using command: install.packages("toscutil") from within a running R session.

🗒️NOTE: In case a function is defined multiple times in the same file. The generated roxygen2 docstring will always be based on the last definition of the function.

testRFunction

Execute test cases for the R function where the cursor is currently positioned.

1. If the file path of the currently edited file matches glob pattern {package_dir}/tests/testthat/test[-_]*.R, command testthat::test_file("${currentFilePath}") is sent to the currently active terminal.
2. If the currently edited file matches glob pattern {package_dir}/**/*.R, the name of the currently edited function is determined and command testthat::test_file("{package_dir}/tests/testthat/test-{currentFunctionName}.R") is sent instead.
3. If the current editor matches neither of the above glob patterns or no terminal is active, nothing happens (except for an info message explaining why).

To speed up the develop-test-cycle even more, you might want to define a shortcut for this command. For instance, I have set up the following binding in my keybindings.json file:

{
    "key": "ctrl+shift+t",
    "command": "vstosc.testRFunction",
    "when": "editorTextFocus && editorLangId == 'r'"
}

knitRmd

Sends the following text to the currently active console:

rmarkdown::render("<path-of-currently-active-file")

mathMode

Inserts ~$$ at the current position and places the cursor in between $$. A potential leading space is removed.

toggleEditorTerminalFocus

Smart focus switching between terminal and editor with `Ctrl+``

This command replaces the default VS Code `Ctrl+`` behavior with intelligent bidirectional focus switching. Instead of just opening the terminal, it toggles between your terminal and editor based on what was previously focused, creating a seamless workflow for rapid switching during development.

The command uses focus tracking to remember whether you were last working in the terminal or editor, ensuring the toggle behavior works correctly even when accessed through the Command Palette.

goToAnything

Lightning-fast navigation to either a document position (line[:column]) or common VS Code UI areas. UI targets jump instantly, while line/column entries follow the classic Go to Line/Column flow (press Enter to confirm).

Default shortcut: Alt+G (Option+G on macOS).

Letters map to the following locations:

Numbers behave like VS Code's built-in Go to Line/Column feature, e.g. 120 jumps to line 120 and 42:15 jumps to line 42, column 15 (1-based). The options list is displayed beneath the input so you can keep the key hints visible while typing.

Contribute

1. Clone this repo and open the folder in VSCode
2. Run npm install to install all dependencies
3. Modify package.json and src/extensions.ts as required (ChatGPT is your friend).
4. Hit F5 to run the extension in a new Extension Development Host window.
5. See Debugging the extension in case something isn't working as expected.
6. Increase the version in package.json according to the rules of Semantic versioning
7. Push your changes and tag the commit (see section publish for details about the publishing process triggered by tagging a commit from the main branch)

Publish

Whenever a commit from the main branch receives a tag, the publish action is triggered, which uploads the extension vsce to the VSCode Marketplace. In case the pipeline fails and you want to do the publishing manually, the following steps would be required:

1. Run npm install -g @vscode/vsce to install the Visual Studio Code Extension Tool.
2. Run vsce package to build the new package in VSCode package format .vsix
3. Login to the VSCode Marketplace using a valid access token for the Azure DevOps Organization toscm using command vsce login toscm
4. Publish the extension using command vsce publish
