"If you only have lemons, make lemonade." Hello,
Thanks for your input. Input Method is part of NLS, and judging from the documentation, http://www.unet.univie.ac.at/aix/aixprggd/genprogc/greek.htm IM is part of X. I'm just wondering what Linux would be like without running an X server. The Linux console 'keymaps' looks like a Single-Byte Input Method (SIM). Other input methods (i.e. JIM, ZIM, KIM, THIM...) look significantly more complex. A SIM scanner should be able to handle most European writing systems, Eastern, Western Latin, Greek, Cyrillic, by just substituting the keymap, but the Greek IM only does Latin and (modern) Greek. Did you say there was a SIM keymap that does polytonic Greek? My cygwin has nothing even coming close to NLS and locales, so I'm going to try to reverse engineer the SIM and see if I can make it work in a DOS console. (I wonder how XFree86 on cygwin responds to NLS.) This is all just idle curiosity. Linux seems to work remarkably well, and X is very good. I'm impressed. At first glance, I didn't understand the literature, but things are becoming clear now. Thanks again. Elvis PS The SIM keymap is only slightly more complex than an array lookup. :-) <attachment> -- naive keymaps -- ordinary symbols representing arbitrary constants Shift = 256 Alt = 512 Ctrl = 1024 -- ordinary symbols representing numeric keycodes alpha = 30 --'a' epsilon = 18 --'e' eta = 35 --'h' omega = 47 --'v' oxia = 53 --'/' varia = 43 --'\\' perispomeni = Shift+41 --'~' ennea = 10 --'9' don't get confused! psili = Shift+ennea --')' mhden = 11 --'0' dasia = Shift+mhden --'(' ypogegrammeni = Shift+varia --'|' -- more constants. symbols representing characters small_omega = 0x03c9 small_omega_varia = 0x1f7c small_omega_varia_ypogegrammeni = 0x1ff2 small_omega_oxia = 0x1f7d small_omega_oxia_ypogegrammeni = 0x1ff4 small_omega_perispomeni = 0x1ff6 small_omega_perispomeni_ypogegrammeni = 0x1ff7 small_omega_psili = 0x1f60 small_omega_psili_varia = 0x1f62 small_omega_psili_varia_ypogegrammeni = 0x1fa2 small_omega_psili_oxia = 0x1f64 small_omega_psili_oxia_ypogegrammeni = 0x1fa4 small_omega_psili_perispomeni = 0x1f66 small_omega_psili_perispomeni_ypogegrammeni = 0x1fa6 small_omega_psili_ypogegrammeni = 0x1fa0 -- This statement defines all the keysyms of keycode 10, -- i.e. ennea, Shift+ennea, Alt+ennea, Alt+Shift+ennea, -- Ctrl+ennea, Ctrl+Shift+ennea, Ctrl+Alt+ennea, -- Ctrl+Alt+Shift+ennea. -- All unnamed keysyms get default values keycode ennea = '9' '(' --ascii character events -- keycode mhden = '0' ')' keycode alpha = small_alpha capital_alpha keycode epsilon = small_epsilon capital_epsilon keycode eta = small_eta capital_eta keycode iota = small_iota capital_iota keycode omicron = small_omicron capital_omicron keycode ypsilon = small_ypsilon capital_ypsilon -- a keysym appears in two contexts, as a 'keycode' -- and as a member of a 'compose' sequence. -- state 0 keysym definition for omega keycode omega = small_omega capital_omega -- state n keysym definitions -- oxia, omega = small_omega_oxia -- omega, oxia = small_omega_oxia compose omega oxia = small_omega_oxia compose oxia omega = small_omega_oxia -- compose varia omega = small_omega_varia compose psili omega = small_omega_psili compose Shift+10 53 47 = 0x1F60 compose psili oxia omega = small_omega_psili_oxia compose psili oxia ypogegrammeni omega = small_omega_psili_oxia_ypogegrammeni; -- a pretty long line compose psili varia omega = small_omega_psili_varia compose psili varia ypogegrammeni omega = small_omega_psili_varia_ypogegrammeni; -- another long line ========================================= ω Ω ->[0]--->[[ω]] ->[0]--->[[Ω]] ω / ->[0]--->[960]--->[[ώ]] / ω ->[0]--->[961]--->[[ώ]] \ ω ->[0]--->[962]--->[[ὼ]] ( ω ->[0]--->[963]--->[[ὡ]] ( / ω ->[0]--->[963]--->[964]--->[[ὤ]] ( / | ω ->[0]--->[963]--->[964]--->[965]--->[[ᾥ]] ( \ ω ->[0]--->[963]--->[966]--->[[ὣ]] ( \ | ω ->[0]--->[963]--->[966]--->[967]--->[[ᾣ]] ========================================= --- Elvis Presley <[EMAIL PROTECTED]> wrote: > Naïve Keymap > > Greetings, > > The 'keymaps' structure seems to boil down to something like this: > > ======================================================= > #include <stdio.h> > > const int map = 3; > enum language {english, greek, russian}; > > const int keysym = 8; > enum modifier {normal=0x0, shift=0x1, alt=0x2 , ctrl=0x4}; > > const int keycode = 120; > // keys are not enumerated. > > int keymap[map][keycode][keysym]; //<---- KEYMAP > > int main(int argc, char *argv[]) > { > keymap[english][30][normal] = 'a'; > keymap[english][30][shift] = 'A'; > keymap[english][30][alt] = 0x1b61; // "\eA" > keymap[english][30][alt+shift] = '?'; > keymap[english][30][ctrl] = 0x01; // SOH > keymap[english][30][ctrl+shift] = '?'; > keymap[english][30][ctrl+alt] = '?'; > keymap[english][30][ctrl+alt+shift] = '?'; > > keymap[english][47][normal] = 'v'; > keymap[english][47][shift] = 'V'; > > keymap[greek][30][normal] = 0x03b1; //α > keymap[greek][30][shift] = 0x0391; //Α > > keymap[greek][47][normal] = 'ω'; > keymap[greek][47][shift] = 'Ω'; > > printf("%C\n", keymap[greek][47][normal]); > return 0; > } > ======================================================= __________________________________ Do you Yahoo!?
