// Description:
|
|
// This class gives tcsh-like shell.
|
|
//
|
|
// If your terminal supports color code, colored strings are available
|
|
// in ListCommand(). For activating color support,
|
|
// e.g.
|
|
// tcsh-> SetLsColor(GREEN, CYAN); // (dir, command) color
|
|
//
|
|
// [key binding]
|
|
// ^A ... move cursor to the top
|
|
// ^B ... backward cursor ([LEFT])
|
|
// ^D ... delete/exit/show matched list
|
|
// ^E ... move cursor to the end
|
|
// ^F ... forward cursor ([RIGHT])
|
|
// ^K ... clear after the cursor
|
|
// ^L ... clear screen (not implemented)
|
|
// ^N ... next command ([DOWN])
|
|
// ^P ... previous command ([UP])
|
|
// TAB... command completion
|
|
// DEL... backspace
|
|
// BS ... backspace
|
|
//
|
|
// [prompt string substitution]
|
|
// %s ... current application status
|
|
// %/ ... current working directory
|
|
// %h ... history# (different from G4 history#)
