801 Cursor/Keypad Support
|
|
|
802
|
|
|
803 Sadly Cursor/Keypad support is less straightforward than it should be.
|
|
|
804
|
|
|
805 The various terminal emulators/consoles choose to differentiate the
|
|
|
806 cursor and keypad keys (with modifiers) in different ways (if at all!).
|
|
|
807 Furthermore they use different code set sequences for each key only
|
|
|
808 a subset of which the various curses libraries recognize. Partly due
|
|
|
809 to incomplete termcap/terminfo entries and partly due to inherent
|
|
|
810 limitations of those terminal capability databases.
|
|
|
811
|
|
|
812 I give curses first crack at decoding the sequences. If it fails to decode
|
|
|
813 it we check for common ESC-prefixed sequences.
|
|
|
814
|
|
|
815 All cursor/keypad results are translated into standard rogue movement
|
|
|
816 commands.
|
|
|
817
|
|
|
818 Unmodified keys are translated to walk commands: hjklyubn
|
|
|
819 Modified (shift,control,alt) are translated to run commands: HJKLYUBN
