60 Cursor/Keypad Support
|
|
|
61
|
|
|
62 Sadly Cursor/Keypad support is less straightforward than it should be.
|
|
|
63
|
|
|
64 The various terminal emulators/consoles choose to differentiate the
|
|
|
65 cursor and keypad keys (with modifiers) in different ways (if at all!).
|
|
|
66 Furthermore they use different code set sequences for each key only
|
|
|
67 a subset of which the various curses libraries recognize. Partly due
|
|
|
68 to incomplete termcap/terminfo entries and partly due to inherent
|
|
|
69 limitations of those terminal capability databases.
|
|
|
70
|
|
|
71 I give curses first crack at decoding the sequences. If it fails to decode
|
|
|
72 it we check for common ESC-prefixed sequences.
|
|
|
73
|
|
|
74 All cursor/keypad results are translated into standard rogue movement
|
|
|
75 commands.
|
|
|
76
|
|
|
77 Unmodified keys are translated to walk commands: hjklyubn
|
|
|
78 Modified (shift,control,alt) are translated to run commands: HJKLYUBN
