Class Method Details

.exec(*args) ⇒ Object

Run the command cmd within a fresh rake-compiler-dock container. The command is run directly, without the shell.

If a block is given, upon command completion the block is called with an OK flag (true on a zero exit status) and a Process::Status object. Without a block a RuntimeError is raised when the command exits non-zero.

Examples:

RakeCompilerDock.exec 'bash', '-c', 'echo $RUBY_CC_VERSION'

.sh(cmd, &block) ⇒ Object

Run the command cmd within a fresh rake-compiler-dock container and within a shell.

If a block is given, upon command completion the block is called with an OK flag (true on a zero exit status) and a Process::Status object. Without a block a RuntimeError is raised when the command exits non-zero.

Examples:

RakeCompilerDock.sh 'bundle && rake cross native gem'

# check exit status after command runs
sh %{bundle && rake cross native gem} do |ok, res|
  if ! ok
    puts "windows cross build failed (status = #{res.exitstatus})"
  end
