Method Detail

getCurrentDirectory

DirectoryResource getCurrentDirectory()

Return the current working directory resource of the shell. Start with getCurrentResource() and move up the hierarchy until a DirectoryResource is found. (This value may change through execution of plug-ins or other operations.)

getCurrentResource

Resource<?> getCurrentResource()

Return the current working Resource of the shell. (This value may change through execution of plug-ins or other operations.) TODO implement ResourceBag for multiple resources

getCurrentResourceScope

Class<? extends Resource<?>> getCurrentResourceScope()

Return the type of the Resource on which the Shell is currently operating.

See Also:

RequiresResource}

setCurrentResource

void setCurrentResource(Resource<?> resource)

Set the Resource on which the shell should operate.

Note: This may change the current getCurrentDirectory()

getConfigDir

DirectoryResource getConfigDir()

Return the file-system directory currently in use as the configuration directory. (Usually "~/.forge/")

getCurrentProject

Project getCurrentProject()

Return the Project on which this shell instance is currently operating.

isExceptionHandlingEnabled

boolean isExceptionHandlingEnabled()

Return true if this shell is currently set to handle exceptions. If exception handling is enabled, this shell will capture all exceptions thrown during command execution; if disabled, exceptions will not be caught, and must be caught outside of the shell to avoid termination.

setExceptionHandlingEnabled

void setExceptionHandlingEnabled(boolean enabled)

Toggle exception handling.

See Also:

#isExceptionHandlingEnabled()}

isAcceptDefaults

boolean isAcceptDefaults()

Return true if this Shell is currently set to accept prompt defaults automatically.

setAcceptDefaults

void setAcceptDefaults(boolean accept)

Set this Shell to accept prompt defaults automatically.

isPretend

boolean isPretend()

Return true if this shell is currently running in pretend mode.

Modifications to files made while running in pretend mode are made in a temporary directory, and the output is produced as a Diff that can then be applied to the project.

isVerbose

boolean isVerbose()

Return true if this shell is currently running in verbose mode.

setVerbose

void setVerbose(boolean verbose)

Toggle verbose mode.

isHistoryEnabled

boolean isHistoryEnabled()

Return true if this shell is currently keeping a record of command history.

setHistoryEnabled

void setHistoryEnabled(boolean history)

Toggle whether or not this shell should keep a record of command history.

printlnVerbose

void printlnVerbose(String output)

Write output to the console, only if isVerbose() == true.

printlnVerbose

void printlnVerbose(ShellColor color,
                  String output)

Write color output to the console, only if isVerbose() == true.

clear

void clear()

Clear the console.

execute

void execute(String command)
             throws Exception

Execute a shell command.

Throws:

Throwable - if an exception is encountered an isExceptionHandlingEnabled() is not enabled.

             throws IOException,
                    Exception

Execute a shell script from the specified file.

Execute a shell script from the specified file, passing the given arguments as input.

Throws:

IOException

Exception

See Also:

#execute(File)}

isExecuting

Return true if the Shell is currently executing a plugin; otherwise, return false.

scan

int scan()

Wait for input. Return as soon as any key is pressed and return the scancode.

clearLine

Throws:

IOException

getHeight

int getHeight()

Return the current height, in characters, of the current shell console. (Warning: This may change in the time between when the method is called and when the result is used. Be sure to call the method as close to its actual use as possible.)

getAbsoluteHeight

int getAbsoluteHeight()

Return the absolute height of the console. This may be different than getHeight() depending on how many lines are available in a display buffer.

Returns:

getWidth

int getWidth()

Return the current width, in characters, of the current shell console. (Warning: This may change in the time between when the method is called and when the result is used. Be sure to call the method as close to its actual use as possible.)

readLine

String readLine()
                throws IOException

Ask the current InputStream for data.

any read data as a string, or null if none available.

Throws:

IOException - on error

setAnsiSupported

void setAnsiSupported(boolean value)

Controls the shell's usage of ANSI escape code support. This method does not guarantee ANSI will function properly, as the underlying Terminal must also support it.
