From 5e507c9829942c434a6f1ae7a4f3a488c7e50bef Mon Sep 17 00:00:00 2001 From: est31 Date: Sat, 25 Jul 2015 07:43:32 +0200 Subject: Add server side ncurses terminal This adds a chat console the server owner can use for administration or to talk with players. It runs in its own thread, which makes the user interface immune to the server's lag, behaving just like a client, except timeout. As it uses the same console code as the f10 console, things like nick completion or a scroll buffer basically come for free. The terminal itself is written in a general way so that adding a client version later on is just about implementing an interface. Fatal errors are printed after the console exists and the ncurses terminal buffer gets cleaned up with endwin(), so that the error still remains visible. The server owner can chose their username their entered text will have in chat and where players can send PMs to. Once the username is secured with a password to prevent anybody to take over the server, the owner can execute admin tasks over the console. This change includes a contribution by @kahrl who has improved ncurses library detection. --- src/util/string.h | 20 +++++++++++++++++++- 1 file changed, 19 insertions(+), 1 deletion(-) (limited to 'src/util') diff --git a/src/util/string.h b/src/util/string.h index 793baad0e..c8f60b802 100644 --- a/src/util/string.h +++ b/src/util/string.h @@ -32,8 +32,26 @@ with this program; if not, write to the Free Software Foundation, Inc., #define STRINGIFY(x) #x #define TOSTRING(x) STRINGIFY(x) +// Checks whether a value is an ASCII printable character +#define IS_ASCII_PRINTABLE_CHAR(x) \ + (((unsigned int)(x) >= 0x20) && \ + ( (unsigned int)(x) <= 0x7e)) + // Checks whether a byte is an inner byte for an utf-8 multibyte sequence -#define IS_UTF8_MULTB_INNER(x) (((unsigned char)x >= 0x80) && ((unsigned char)x < 0xc0)) +#define IS_UTF8_MULTB_INNER(x) \ + (((unsigned char)(x) >= 0x80) && \ + ( (unsigned char)(x) <= 0xbf)) + +// Checks whether a byte is a start byte for an utf-8 multibyte sequence +#define IS_UTF8_MULTB_START(x) \ + (((unsigned char)(x) >= 0xc2) && \ + ( (unsigned char)(x) <= 0xf4)) + +// Given a start byte x for an utf-8 multibyte sequence +// it gives the length of the whole sequence in bytes. +#define UTF8_MULTB_START_LEN(x) \ + (((unsigned char)(x) < 0xe0) ? 2 : \ + (((unsigned char)(x) < 0xf0) ? 3 : 4)) typedef std::map StringMap; -- cgit v1.2.3
