From dcebf9c7f954a55350b68d0ead1935612c4e2e05 Mon Sep 17 00:00:00 2001 From: Berke Güzel Date: Thu, 15 Oct 2026 13:04:01 +0300 Subject: Rename the library to wsap_vtcore ncurses installs and defines struct term. In a file that includes both headers, an ncurses TERMINAL * and this library's terminal are silently the same type. The name wsap_vtcore avoids the clash. The public header is now . Every global symbol uses the wsap_vtcore_ prefix, every macro uses WSAP_VTCORE_, and the shared library is libwsap_vtcore.so.0. The default terminal name is now "wsap_vtcore". The ISA override variable is WSAP_VTCORE_ISA. No other behavior changes. The amalgamation writes wsap_vtcore.c and wsap_vtcore.h.
