| config PDCURSES_WIDE |
| bool "Wide character support" |
| default n |
| depends on EXPERIMENTAL |
| |
| config PDCURSES_FORCE_UTF8 |
| bool "Force UTF8 character set" |
| default n |
| depends on PDCURSES_WIDE |
| |
| config PDCURSES_CHTYPE_LONG |
| bool "32-bit chtype" |
| default n |
| |
| config PDCURSES_DEBUG |
| bool "Enable pdcurses debug output" |
| default n |
| |
| config PDCURSES_PANEL_DEBUG |
| bool "Enable special debug output for panels" |
| default n |
| |
| config PDCURSES_MULTITHREAD |
| bool "Enable code for running pdcurses from multiple threads (removes global variables)." |
| default n |
| ---help--- |
| The base pdcurses code uses global and function static variables, |
| preventing multiple tasks from using pdcurses in a FLAT model. |
| This option collects all those variables into a thread specific |
| dynamically allocated context, enabling multiple tasks to use |
| pdcurses concurrently at the cost of a slight execution speed |
| penalty for performing per task context lookup. |
| |
| config PDCURSES_MULTITHREAD_HASH |
| bool "Use PID HASH lookup for thread specific pdcurses context data." |
| depends on PDCURSES_MULTITHREAD |
| default n |
| ---help--- |
| Without this option, the per task pdcurses logic uses a linked list |
| of allocated contexts, keeping RAM usage to a minimum at the expense |
| of execution time for semaphore locking / unlocking and list traversal. |
| This option enables a PID hash lookup option which eliminates the |
| need for this extra logic by using a statically allocated array of |
| context pointers whose size is dictated by the MAX_TASKS config variable. |
| |
| Enabling this option allows simple hash calculation and array lookup at |
| the expense of extra RAM usage for the static array of context pointers. |
| |
| config PDCURSES_SHORT_ALTCHARSET |
| bool "Allow alternate character set with short 16-bit chtype" |
| depends on !PDCURSES_CHTYPE_LONG && !PDCURSES_FORCE_UTF8 |
| default y |
| ---help--- |
| The alternate character set includes graphic line drawing characters |
| used for drawing box borders. When using 16-bit chtype, the base |
| pdcurses does not define a bit for A_ALTCHARSET. This option uses |
| the MSB of the 8-bit character code as A_ALTCHARSET to enable line |
| drawing characters. |
| |
| Enabling this means limiting the usable normal character set to the |
| base 7-bit ASCII characters, however for most VT-100 / ANSI emulators, |
| the upper bits are either not defined or not critical. |
