Phillip Webb c8a1d8830c Refactor CLI internals for REPL shell ... Numerous updates to the Spring CLI, primarily for better embedded REPL shell support: * Refactor the CLI application to help separate concerts between the main CLI and the embedded shell. Both the CLI and embedded shell now delegate to a new `CommandRunner` to handle running commands. The runner can be configured differently depending depending on need. For example, the embedded shell adds the 'prompt' and 'clear' commands. * Most `Command` implementations have been moved to sub-packages so that they can be co-located with the classes that they use. * Option commands are now only used in the CLI, the embedded shell does not user them and details have been removed from the Command interface. * The REPL shell has been significantly refactored to: - Support CTRL-C to cancel the running process. This is supported when running external commands and most internal commands. - Fork a new JVM when running commands (primarily for CTRL-C support but also for potential memory and classpath issues) - Change the "continue" trigger from `<<` to `\` - Support command completion of files - Add ANSI color output - Provide 'help' support for internal commands (such as 'clear') - Remove the now redundant `stop` command Fixes gh-227		2014-01-15 14:03:18 -08:00
