41 // ====================================================================
42 // Description:
43 // This class gives tcsh-like shell.
44 //
45 // If your terminal supports color code, colored strings are available
46 // in ListCommand(). For activating color support,
47 // e.g.
48 // tcsh-> SetLsColor(GREEN, CYAN); // (dir, command) color
49 //
50 // [key binding]
51 // ^A ... move cursor to the top
52 // ^B ... backward cursor ([LEFT])
53 // ^D ... delete/exit/show matched list
54 // ^E ... move cursor to the end
55 // ^F ... forward cursor ([RIGHT])
56 // ^K ... clear after the cursor
57 // ^L ... clear screen (not implemented)
58 // ^N ... next command ([DOWN])
59 // ^P ... previous command ([UP])
60 // TAB... command completion
61 // DEL... backspace
62 // BS ... backspace
63 //
64 // [prompt string substitution]
65 // %s ... current application status
66 // %/ ... current working directory
67 // %h ... history# (different from G4 history#)
