Below is the full text to src/vis_tab.c from NetHack 3.4.3, as generated when the VISION_TABLES symbol is enabled at compile time. To link to a particular line, write [[vis_tab.c (long form)#line123]], for example. /* This source file is generated by 'makedefs'. Do not edit. */ A clean distribution of NetHack does not include this file. It is generated at compile time. If the VISION_TABLES symbol is not defined at compile time, makedefs produces a shorter form of this file.
