From: Thomas Cort Date: Wed, 25 Mar 2015 18:32:43 +0000 (-0400) Subject: mined: built without UNIX defined. X-Git-Url: http://zhaoyanbai.com/repos/%22http:/www.isc.org/icons/zpipe.c?a=commitdiff_plain;h=e978660932e3296e119f57620bc8c08d100c42fb;p=minix.git mined: built without UNIX defined. * Remove undef NULL, EOF, getchar, putchar * Rename putchar, getchar, _putchar, _getchar to putch, getch, _putch, _getch to avoid conflict with libc functions. * Rename UP() to UP1() (for UP 1 line) to avoid conflict with UP definition in termcap.h. Rename DN1 LF1 RT1 for consistency. * Add termcap.h for prototypes for tputs and friends. * Add libterminfo references to Makefile * Add return value to _putch() to make it work as tputs expects. * Make putch() call _putch() * Remove UNIX ifdefs and all code in the !UNIX branches. closes #43 Change-Id: I0a6f7298aa8b12a74225badc88d3c236a02669ea --- diff --git a/minix/commands/mined/Makefile b/minix/commands/mined/Makefile index d20eebd0b..39ba9f5a6 100644 --- a/minix/commands/mined/Makefile +++ b/minix/commands/mined/Makefile @@ -3,4 +3,9 @@ PROG= mined SRCS= mined1.c mined2.c +CPPFLAGS+= -I${.CURDIR}/../../../lib/libterminfo + +DPADD+= ${LIBTERMINFO} +LDADD+= -lterminfo + .include diff --git a/minix/commands/mined/mined.h b/minix/commands/mined/mined.h index 04c4f8af9..0832988eb 100644 --- a/minix/commands/mined/mined.h +++ b/minix/commands/mined/mined.h @@ -6,30 +6,13 @@ #include #include #include +#include #include #include - -#ifndef YMAX -#ifdef UNIX #include -#undef putchar -#undef getchar -#undef NULL -#undef EOF -extern char *CE, *VS, *SO, *SE, *CL, *AL, *CM; -#define YMAX 49 -#else -#define YMAX 24 /* Maximum y coordinate starting at 0 */ -/* Escape sequences. */ -extern char *enter_string; /* String printed on entering mined */ -extern char *rev_video; /* String for starting reverse video */ -extern char *normal_video; /* String for leaving reverse video */ -extern char *rev_scroll; /* String for reverse scrolling */ -extern char *pos_string; /* Absolute cursor positioning */ -#define X_PLUS ' ' /* To be added to x for cursor sequence */ -#define Y_PLUS ' ' /* To be added to y for cursor sequence */ -#endif /* UNIX */ +extern char *CE, *VS, *SO, *SE, *CL, *AL, *CM; +#define YMAX 49 /* Maximum y coordinate starting at 0 */ #define XMAX 79 /* Maximum x coordinate starting at 0*/ #define SCREENMAX (YMAX - 1) /* Number of lines displayed */ #define XBREAK (XMAX - 0) /* Line shift at this coordinate */ @@ -163,12 +146,12 @@ extern long chars_saved; /* Nr of chars saved in buffer */ /* * Print character on terminal */ -#define putchar(c) (void) write_char(STD_OUT, (c)) +#define putch(c) _putch((c)) /* * Ring bell on terminal */ -#define ring_bell() putchar('\07') +#define ring_bell() putch('\07') /* * Print string on terminal @@ -229,8 +212,6 @@ extern long chars_saved; /* Nr of chars saved in buffer */ */ #define get_shift(cnt) ((cnt) & DUMMY_MASK) -#endif /* YMAX */ - /* mined1.c */ void FS(void); @@ -250,7 +231,7 @@ void copy_string(char *to, char *from ); void reset(LINE *head_line, int screen_y ); void set_cursor(int nx, int ny ); void open_device(void); -int getchar(void); +int getch(void); void display(int x_coord, int y_coord, LINE *line, int count ); int write_char(int fd, int c ); int writeline(int fd, char *text ); @@ -263,13 +244,6 @@ void raw_mode(FLAG state ); void panic(char *message ); char *alloc(int bytes ); void free_space(char *p ); -/* -#ifdef UNIX -void(*key_map [128]) (void); -#else -void(*key_map [256]) (void); -#endif -*/ void initialize(void); char *basename(char *path ); void load_file(char *file ); @@ -293,17 +267,17 @@ char *num_out(long number ); int get_number(char *message, int *result ); int input(char *inbuf, FLAG clearfl ); int get_file(char *message, char *file ); -int _getchar(void); +int _getch(void); void _flush(void); -void _putchar(int c ); +int _putch(int c ); void get_term(void); /* mined2.c */ -void UP(void); -void DN(void); -void LF(void); -void RT(void); +void UP1(void); +void DN1(void); +void LF1(void); +void RT1(void); void HIGH(void); void LOW(void); void BL(void); diff --git a/minix/commands/mined/mined1.c b/minix/commands/mined/mined1.c index 154d6c7e8..de8bd6d1f 100644 --- a/minix/commands/mined/mined1.c +++ b/minix/commands/mined/mined1.c @@ -153,7 +153,7 @@ * 3.3 Moving around. * * Several commands are implemented for moving through the file. - * Moving up (UP), down (DN) left (LF) and right (RT) are done by the + * Moving up (UP1), down (DN1) left (LF1) and right (RT1) are done by the * arrow keys.
