Check if required packages for build are available — projr_build_check

Checks if all packages required for the current project build are installed. Returns structured information about missing packages and installation commands.

This is particularly useful in CI/CD environments where the installation commands need to be captured and executed programmatically.

Usage

projr_build_check_packages(profile = NULL)

Arguments

profile: character. projr profile to use. Default is NULL (use current profile).

Value

A list with the following elements:

available: Logical. TRUE if all required packages are installed, FALSE otherwise.
missing: Character vector of missing package names. Empty if all packages are available.
install_cmds: Character vector of R commands to install missing packages. Empty if all packages are available.
message: Character. Human-readable message about package status.

Examples

if (FALSE) { # \dontrun{
# Check packages for current project
pkg_status <- projr_build_check_packages()

if (!pkg_status$available) {
  cat("Missing packages:", paste(pkg_status$missing, collapse = ", "), "\n")
  cat("Install commands:\n")
  cat(paste(pkg_status$install_cmds, collapse = "\n"), "\n")

  # In CI/CD, you could execute:
  # for (cmd in pkg_status$install_cmds) {
  #   eval(parse(text = cmd))
  # }
}
} # }
