Depends

Check that dev dependencies are installed before building. This is useful for ensuring development tools like testing frameworks, documentation generators, or linting packages are available.

CLI Usage

builder -depends testthat devtools roxygen2

Config Usage

depends: testthat devtools roxygen2

Behavior

• Checks each package with requireNamespace()
• If any package is missing, build fails with an error
• All missing packages are reported before exiting

Example

# Check dev dependencies before building
builder -depends testthat covr lintr

# Combined with other options
builder -input srcr/ -depends testthat devtools

This is intended for development dependencies - packages needed during the build process but not necessarily at runtime.
