So... for these generally-useful characters, what should +dnl be the width (to make them consistent with adjacent characters)? +dnl +dnl The obvious choice would have been to make this locale-dependent, and use +dnl wcwidth() to tell applications what the actual width is. That was too +dnl obvious. Instead, we have a slew of "ambiguous-width" characters. +dnl See for example +dnl http://www.unicode.org/reports/tr11/tr11-29.html +dnl http://www.cl.cam.ac.uk/~mgk25/ucs/scw-proposal.html +dnl +dnl The EastAsianWidth-6.2.0.txt file from the Unicode organization lists +dnl more than 22,000 characters, with 1281 of those as ambiguous-width. For +dnl instance, it lists half (44/96) of the Latin-1 characters as +dnl ambiguous-width. Also, all of the box-characters at 0x2500 are ambiguous. +dnl +dnl What this means for the implementor is that on some systems wcwidth() can +dnl give bad advice. On Solaris, some of the ambiguous widths are returned as +dnl 1 (the Latin-1 characters), while others are returned as 2 (line-drawing +dnl characters). These do not necessarily match the behavior of the terminal +dnl emulator. xterm, for instance, does an optional startup check to find if +dnl this problem (or similar) exists with the system's locale tables, rejecting +dnl them if they are too unreliable. +AC_DEFUN([CF_CHECK_WCWIDTH_GRAPHICS],[ +AC_CACHE_CHECK(if wcwidth agrees graphics are single-width, cf_cv_wcwidth_graphics,[ +cat >conftest.in < +#include + +#define MY_LEN 80 + +int +main(void) +{ + FILE *fp; + unsigned value; + char buffer[MY_LEN + 1]; + char notes[MY_LEN + 1]; + int totals = 0; + int passed = 0; + + if (setlocale(LC_ALL, "en_US.UTF8") || + setlocale(LC_ALL, "en_US.UTF-8") || + setlocale(LC_ALL, "en_US.utf8") || + setlocale(LC_ALL, "en_US.utf-8")) { + if ((fp = fopen("conftest.in", "r")) != 0) { + while (fgets(buffer, MY_LEN, fp) != 0) { + if (*buffer == '-') { + fprintf(stderr, "\\t%s", buffer); + } else if (sscanf(buffer, "%x %s", &value, notes) == 2) { + ++totals; + if (wcwidth((int)value) == 1) + ++passed; + fprintf(stderr, "%d\\t%s", wcwidth((int)value), buffer); + } else { + fprintf(stderr, "?\\t%s", buffer); + } + } + } + } + fprintf(stderr, "%d/%d passed wcwidth/graphics check\\n", passed, totals); + return (totals == passed) ? 0 : 1; +} +], +[cf_cv_wcwidth_graphics=yes], +[cf_cv_wcwidth_graphics=no], +[cf_cv_wcwidth_graphics=unknown]) +]) +])dnl +dnl --------------------------------------------------------------------------- +dnl CF_CLANG_COMPILER version: 9 updated: 2023/02/18 17:41:25 dnl ----------------- dnl Check if the given compiler is really clang. clang's C driver defines dnl __GNUC__ (fooling the configure script into setting $GCC to yes) but does @@ -1025,24 +1635,156 @@ dnl $3 = CFLAGS (default) or CXXFLAGS AC_DEFUN([CF_CLANG_COMPILER],[ ifelse([$2],,CLANG_COMPILER,[$2])=no -if test "$ifelse([$1],,[$1],GCC)" = yes ; then - AC_MSG_CHECKING(if this is really Clang ifelse([$1],GXX,C++,C) compiler) - cf_save_CFLAGS="$ifelse([$3],,CFLAGS,[$3])" - ifelse([$3],,CFLAGS,[$3])="$ifelse([$3],,CFLAGS,[$3]) -Qunused-arguments" - AC_TRY_COMPILE([],[ -#ifdef __clang__ -#else -make an error -#endif -],[ifelse([$2],,CLANG_COMPILER,[$2])=yes -cf_save_CFLAGS="$cf_save_CFLAGS -Qunused-arguments" -],[]) - ifelse([$3],,CFLAGS,[$3])="$cf_save_CFLAGS" - AC_MSG_RESULT($ifelse([$2],,CLANG_COMPILER,[$2])) -fi +if test "$ifelse([$1],,[$1],GCC)" = yes ; then + AC_MSG_CHECKING(if this is really Clang ifelse([$1],GXX,C++,C) compiler) + cf_save_CFLAGS="$ifelse([$3],,CFLAGS,[$3])" + AC_TRY_COMPILE([],[ +#ifdef __clang__ +#else +#error __clang__ is not defined +#endif +],[ifelse([$2],,CLANG_COMPILER,[$2])=yes +],[]) + ifelse([$3],,CFLAGS,[$3])="$cf_save_CFLAGS" + AC_MSG_RESULT($ifelse([$2],,CLANG_COMPILER,[$2])) +fi + +CLANG_VERSION=none + +if test "x$ifelse([$2],,CLANG_COMPILER,[$2])" = "xyes" ; then + case "$CC" in + (c[[1-9]][[0-9]]|*/c[[1-9]][[0-9]]) + AC_MSG_WARN(replacing broken compiler alias $CC) + CFLAGS="$CFLAGS -std=`echo "$CC" | sed -e 's%.*/%%'`" + CC=clang + ;; + esac + + AC_MSG_CHECKING(version of $CC) + CLANG_VERSION="`$CC --version 2>/dev/null | sed -e '2,$d' -e 's/^.*(CLANG[[^)]]*) //' -e 's/^.*(Debian[[^)]]*) //' -e 's/^[[^0-9.]]*//' -e 's/[[^0-9.]].*//'`" + test -z "$CLANG_VERSION" && CLANG_VERSION=unknown + AC_MSG_RESULT($CLANG_VERSION) + + for cf_clang_opt in \ + -Qunused-arguments \ + -Wno-error=implicit-function-declaration + do + AC_MSG_CHECKING(if option $cf_clang_opt works) + cf_save_CFLAGS="$CFLAGS" + CFLAGS="$CFLAGS $cf_clang_opt" + AC_TRY_LINK([ + #include ],[ + printf("hello!\\n");],[ + cf_clang_optok=yes],[ + cf_clang_optok=no]) + AC_MSG_RESULT($cf_clang_optok) + CFLAGS="$cf_save_CFLAGS" + if test "$cf_clang_optok" = yes; then + CF_VERBOSE(adding option $cf_clang_opt) + CF_APPEND_TEXT(CFLAGS,$cf_clang_opt) + fi + done +fi +]) +dnl --------------------------------------------------------------------------- +dnl CF_CONST_X_STRING version: 8 updated: 2023/12/01 17:22:50 +dnl ----------------- +dnl The X11R4-X11R6 Xt specification uses an ambiguous String type for most +dnl character-strings. +dnl +dnl It is ambiguous because the specification accommodated the pre-ANSI +dnl compilers bundled by more than one vendor in lieu of providing a standard C +dnl compiler other than by costly add-ons.
