From: Akira TAGOH Date: Mon, 6 Dec 2010 03:10:17 +0000 (+0900) Subject: Add charset editing feature. X-Git-Tag: root-2~35^2~4 X-Git-Url: https://git.wh0rd.org/?a=commitdiff_plain;h=857b7efe1e301f670329c6836da52fbab8c5df66;p=fontconfig.git Add charset editing feature. The syntax to add any characters to the charset table looks like: Buggy Sans charset 0x3220 To remove any characters from the charset table: Buggy Sans charset 0x06CC 0x06D2 0x06D3 You could also use the range element for convenience: ... 0x06CC 0x06D2 0x06D3 ... --- diff --git a/fonts.dtd b/fonts.dtd index cbdfdab..5f21e35 100644 --- a/fonts.dtd +++ b/fonts.dtd @@ -196,8 +196,8 @@ - - + + diff --git a/src/Makefile.am b/src/Makefile.am index 59b9c75..96500b4 100644 --- a/src/Makefile.am +++ b/src/Makefile.am @@ -140,7 +140,7 @@ PUBLIC_FILES = \ $(top_srcdir)/fontconfig/fontconfig.h \ $(top_srcdir)/src/fcdeprecate.h \ $(top_srcdir)/fontconfig/fcprivate.h - + PUBLIC_FT_FILES = \ $(top_srcdir)/fontconfig/fcfreetype.h @@ -160,7 +160,7 @@ fontconfig.def: $(PUBLIC_FILES) $(PUBLIC_FT_FILES) echo Generating $@ (echo EXPORTS; \ (cat $(PUBLIC_FILES) $(PUBLIC_FT_FILES) || echo 'FcERROR ()' ) | \ - grep '^Fc[^ ]* *(' | sed -e 's/ *(.*$$//' -e 's/^/ /' | \ + grep '^Fc[^ ]* *(' | sed -e 's/ *(.*$$//' -e 's/^/ /' | \ sort; \ echo LIBRARY libfontconfig-@LIBT_CURRENT_MINUS_AGE@.dll; \ echo VERSION @LIBT_CURRENT@.@LIBT_REVISION@) >$@ diff --git a/src/fccfg.c b/src/fccfg.c index 19a9fef..ad9f7d2 100644 --- a/src/fccfg.c +++ b/src/fccfg.c @@ -1036,6 +1036,25 @@ FcConfigEvaluate (FcPattern *p, FcExpr *e) break; } break; + case FcTypeCharSet: + switch (e->op) { + case FcOpPlus: + v.type = FcTypeCharSet; + v.u.c = FcCharSetUnion (vl.u.c, vr.u.c); + if (!v.u.c) + v.type = FcTypeVoid; + break; + case FcOpMinus: + v.type = FcTypeCharSet; + v.u.c = FcCharSetSubtract (vl.u.c, vr.u.c); + if (!v.u.c) + v.type = FcTypeVoid; + break; + default: + v.type = FcTypeVoid; + break; + } + break; default: v.type = FcTypeVoid; break; diff --git a/src/fcdbg.c b/src/fcdbg.c index fc3b596..79e1953 100644 --- a/src/fcdbg.c +++ b/src/fcdbg.c @@ -160,6 +160,7 @@ FcOpPrint (FcOp op) case FcOpDouble: printf ("Double"); break; case FcOpString: printf ("String"); break; case FcOpMatrix: printf ("Matrix"); break; + case FcOpRange: printf ("Range"); break; case FcOpBool: printf ("Bool"); break; case FcOpCharSet: printf ("CharSet"); break; case FcOpField: printf ("Field"); break; @@ -210,6 +211,7 @@ FcExprPrint (const FcExpr *expr) expr->u.mval->xy, expr->u.mval->yx, expr->u.mval->yy); break; + case FcOpRange: break; case FcOpBool: printf ("%s", expr->u.bval ?
