annotate srogue/mdport.c @ 96:9fb343307b6b
Fix some 'test' failures when running 'make install'.
When shell variables are unexpectedly empty, 'test' gets the wrong
number of arguments and becomes unhappy. Logical AND should not be
done with 'test EXPR1 -a EXPR2' in such cases, because 'test' logic
does not short-circuit. Replace with 'test EXPR1 && test EXPR2'.
Shell logic does short-circuit, and if the first test invocation
fails, the second will never occur, and will never encounter missing
arguments.

| 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 | |
