Constructor Detail

LaunchConfig

public LaunchConfig(Ruby runtime,
                    IRubyObject[] rawArgs,
                    boolean doExecutableSearch)

Method Detail

shouldRunInProcess

public boolean shouldRunInProcess()

Only run an in-process script if the script name has "ruby", ".rb", or "irb" in the name.

shouldRunInShell

public boolean shouldRunInShell()

This hack is to work around a problem with cmd.exe on windows where it can't interpret a filename with spaces in the first argument position as a command. In that case it's better to try passing the bare arguments to runtime.exec. On all other platforms we'll always run the command in the shell.

verifyExecutableForShell

public void verifyExecutableForShell()

verifyExecutableForDirect

public void verifyExecutableForDirect()

verifyExecutable

private void verifyExecutable()

getExecArgs

public java.lang.String[] getExecArgs()

isBatch

private static boolean isBatch(java.io.File f)

isCmdBuiltin

private boolean isCmdBuiltin(java.lang.String cmd)

hasRedirection

private static boolean hasRedirection(java.lang.String cmdline)

Checks a command string to determine if it has I/O redirection characters that require it to be executed by a command interpreter.

shouldVerifyPathExecutable

private static boolean shouldVerifyPathExecutable(java.lang.String cmdline)
