pline
pline is the catch-all function that outputs text to the message area. Depending on the GUI used and how many messages there already are in the message area, NetHack may wait for player to press a key at a --more-- prompt before showing the message.
pline accepts a string constant and any number of additional values that replace placeholders marked with '%' in the string constant, just like printf does.
Example:
int count; for (count = 1; count < 10; count++) { pline("%i", count); } pline("Hello, player!");
46. void 47. pline VA_DECL(const char *, line) 48. #endif /* USE_STDARG | USE_VARARG */ 49. 50. char pbuf[BUFSZ]; 51. /* Do NOT use VA_START and VA_END in here... see above */ 52. 53. if (!line || !*line) return; 54. if (index(line, '%')) { 55. Vsprintf(pbuf,line,VA_ARGS); 56. line = pbuf; 57. } 58. if (!iflags.window_inited) { 59. raw_print(line); 60. return; 61. } 62. #ifndef MAC 63. if (no_repeat && !strcmp(line, toplines)) 64. return; 65. #endif /* MAC */ 66. if (vision_full_recalc) vision_recalc(0); 67. if (u.ux) flush_screen(1); /* %% */ 68. putstr(WIN_MESSAGE, 0, line); 69. } 70.
Norep
Norep() is similar to pline(), but if the same message is repeated after another, it's not shown again.
Example:
int x; for (x = 0; x < 100; x++) { Norep("Whee!"); }
71. /*VARARGS1*/ 72. void 73. Norep VA_DECL(const char *, line) 74. VA_START(line); 75. VA_INIT(line, const char *); 76. no_repeat = TRUE; 77. vpline(line, VA_ARGS); 78. no_repeat = FALSE; 79. VA_END(); 80. return; 81. } 82.
You_buf
83. /* work buffer for You(), &c and verbalize() */ 84. static char *you_buf = 0; 85. static int you_buf_siz = 0; 86. 87. static char * 88. You_buf(siz) 89. int siz; 90. { 91. if (siz > you_buf_siz) { 92. if (you_buf) free((genericptr_t) you_buf); 93. you_buf_siz = siz + 10; 94. you_buf = (char *) alloc((unsigned) you_buf_siz); 95. } 96. return you_buf; 97. } 98.
free_youbuf
99. void 100. free_youbuf() 101. { 102. if (you_buf) free((genericptr_t) you_buf), you_buf = (char *)0; 103. you_buf_siz = 0; 104. } 105.
106. /* `prefix' must be a string literal, not a pointer */ 107. #define YouPrefix(pointer,prefix,text) \ 108. Strcpy((pointer = You_buf((int)(strlen(text) + sizeof prefix))), prefix) 109. 110. #define YouMessage(pointer,prefix,text) \ 111. strcat((YouPrefix(pointer, prefix, text), pointer), text) 112.
You
You() is similar to pline(), but the string is prefixed with "You "
Example:
You("succeed in opening the tin.");
113. /*VARARGS1*/ 114. void 115. You VA_DECL(const char *, line) 116. char *tmp; 117. VA_START(line); 118. VA_INIT(line, const char *); 119. vpline(YouMessage(tmp, "You ", line), VA_ARGS); 120. VA_END(); 121. } 122.
Your
Your() is similar to pline(), but the string is prefixed with "Your "
Example:
Your("wallet is empty.");
123. /*VARARGS1*/ 124. void 125. Your VA_DECL(const char *,line) 126. char *tmp; 127. VA_START(line); 128. VA_INIT(line, const char *); 129. vpline(YouMessage(tmp, "Your ", line), VA_ARGS); 130. VA_END(); 131. } 132.
You_feel
You_feel() is similar to pline(), but the string is prefixed with "You feel "
Example:
You_feel("much better!");
133. /*VARARGS1*/ 134. void 135. You_feel VA_DECL(const char *,line) 136. char *tmp; 137. VA_START(line); 138. VA_INIT(line, const char *); 139. vpline(YouMessage(tmp, "You feel ", line), VA_ARGS); 140. VA_END(); 141. } 142. 143.
You_cant
You_cant() is similar to pline(), but the string is prefixed with "You can't "
Example:
You_cant("wear that!");
144. /*VARARGS1*/ 145. void 146. You_cant VA_DECL(const char *,line) 147. char *tmp; 148. VA_START(line); 149. VA_INIT(line, const char *); 150. vpline(YouMessage(tmp, "You can't ", line), VA_ARGS); 151. VA_END(); 152. } 153.
pline_The
pline_The() is similar to pline(), but the string is prefixed with "The "
Example:
pline_The("door resists!");
154. /*VARARGS1*/ 155. void 156. pline_The VA_DECL(const char *,line) 157. char *tmp; 158. VA_START(line); 159. VA_INIT(line, const char *); 160. vpline(YouMessage(tmp, "The ", line), VA_ARGS); 161. VA_END(); 162. } 163.
There
There() is similar to pline(), but the string is prefixed with "There "
Example:
There("are no seats in here!");
164. /*VARARGS1*/ 165. void 166. There VA_DECL(const char *,line) 167. char *tmp; 168. VA_START(line); 169. VA_INIT(line, const char *); 170. vpline(YouMessage(tmp, "There ", line), VA_ARGS); 171. VA_END(); 172. } 173.
You_hear
You_hear() is similar to pline(), but the string is prefixed with different things depeneding whether the hero is under water, asleep or awake.
Example:
You_hear("crashing rock.");
174. /*VARARGS1*/ 175. void 176. You_hear VA_DECL(const char *,line) 177. char *tmp; 178. VA_START(line); 179. VA_INIT(line, const char *); 180. if (Underwater) 181. YouPrefix(tmp, "You barely hear ", line); 182. else if (u.usleep) 183. YouPrefix(tmp, "You dream that you hear ", line); 184. else 185. YouPrefix(tmp, "You hear ", line); 186. vpline(strcat(tmp, line), VA_ARGS); 187. VA_END(); 188. } 189.
verbalize
verbalize() is similar to pline(), but the string is prefixed and suffixed with double quotes, making it seem as if something said it. If hero cannot hear, this outputs nothing.
Example:
verbalize("You freed me!");
190. /*VARARGS1*/ 191. void 192. verbalize VA_DECL(const char *,line) 193. char *tmp; 194. if (!flags.soundok) return; 195. VA_START(line); 196. VA_INIT(line, const char *); 197. tmp = You_buf((int)strlen(line) + sizeof "\"\""); 198. Strcpy(tmp, "\""); 199. Strcat(tmp, line); 200. Strcat(tmp, "\""); 201. vpline(tmp, VA_ARGS); 202. VA_END(); 203. } 204.
raw_printf
raw_printf() is only used if the GUI isn't yet initialized, but we still need to tell the player something important. For example, config file errors are output with this. Accepts the same kind of variable parameters as pline().
205. /*VARARGS1*/ 206. /* Note that these declarations rely on knowledge of the internals 207. * of the variable argument handling stuff in "tradstdc.h" 208. */ 209. 210. #if defined(USE_STDARG) || defined(USE_VARARGS) 211. static void FDECL(vraw_printf,(const char *,va_list)); 212. 213. void 214. raw_printf VA_DECL(const char *, line) 215. VA_START(line); 216. VA_INIT(line, char *); 217. vraw_printf(line, VA_ARGS); 218. VA_END(); 219. } 220. 221. # ifdef USE_STDARG 222. static void 223. vraw_printf(const char *line, va_list the_args) { 224. # else 225. static void 226. vraw_printf(line, the_args) const char *line; va_list the_args; { 227. # endif 228. 229. #else /* USE_STDARG | USE_VARARG */ 230. 231. void 232. raw_printf VA_DECL(const char *, line) 233. #endif 234. /* Do NOT use VA_START and VA_END in here... see above */ 235. 236. if(!index(line, '%')) 237. raw_print(line); 238. else { 239. char pbuf[BUFSZ]; 240. Vsprintf(pbuf,line,VA_ARGS); 241. raw_print(pbuf); 242. } 243. } 244. 245.
impossible
impossible() is used to tell the player that NetHack thinks something is wrong. This might or might not be bad enough that NetHack will crash. It accepts the same parameters as pline().
246. /*VARARGS1*/ 247. void 248. impossible VA_DECL(const char *, s) 249. VA_START(s); 250. VA_INIT(s, const char *); 251. if (program_state.in_impossible) 252. panic("impossible called impossible"); 253. program_state.in_impossible = 1; 254. { 255. char pbuf[BUFSZ]; 256. Vsprintf(pbuf,s,VA_ARGS); 257. paniclog("impossible", pbuf); 258. } 259. vpline(s,VA_ARGS); 260. pline("Program in disorder - perhaps you'd better #quit."); 261. program_state.in_impossible = 0; 262. VA_END(); 263. } 264.
align_str
align_str() takes one parameter, an alignment, and returns a string describing it.
265. const char * 266. align_str(alignment) 267. aligntyp alignment; 268. { 269. switch ((int)alignment) { 270. case A_CHAOTIC: return "chaotic"; 271. case A_NEUTRAL: return "neutral"; 272. case A_LAWFUL: return "lawful"; 273. case A_NONE: return "unaligned"; 274. } 275. return "unknown"; 276. } 277.
