From 9fbd9ce5cadeb91ed28f18559e80d0bb5a2e1d54 Mon Sep 17 00:00:00 2001 From: Kristaps Dzonsons Date: Tue, 17 May 2011 22:32:45 +0000 Subject: Locale support. I'm checking this in to clean up fall-out in-tree, but it looks pretty good. Basically, the -Tlocale option propogates into term_ascii.c, where we set locale-specific console call-backs IFF (1) setlocale() works; (2) locale support is compiled in (see Makefile for -DUSE_WCHAR); (3) the internal structure of wchar_t maps directly to Unicode codepoints as defined by __STDC_ISO_10646__; and (4) the console supports multi-byte characters. To date, this configuration only supports GNU/Linux. OpenBSD doesn't export __STDC_ISO_10646__ although I'm told by stsp@openbsd.org that it should (it has the correct map). Apparently FreeBSD is the same way. NetBSD? Don't know. Apple also supports this, but doesn't define the macro. Special-casing! Benchmark: -Tlocale incurs less than 0.2 factor overhead when run through several thousand manuals when UTF8 output is enabled. Native mode (whether directly -Tascii or through no locale or whatever) is UNCHANGED: the function callbacks are the same as before. Note. If the underlying system does NOT support STDC_ISO_10646, there is a "slow" version possible with iconv or other means of flipping from a Unicode codepoint to a wchar_t. --- Makefile | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) (limited to 'Makefile') diff --git a/Makefile b/Makefile index cc3fb743..a88b57b6 100644 --- a/Makefile +++ b/Makefile @@ -13,7 +13,10 @@ VERSION = 1.11.2 VDATE = 12 May 2011 -CFLAGS += -g -DHAVE_CONFIG_H -DVERSION="\"$(VERSION)\"" +# If your system doesn't support multi-byte functions (specifically +# setlocale(), wcwidth(), putwchar()), then remove -DUSE_CHAR.
