mdbFontset(5)							 The m17n Library						     mdbFontset(5)

NAME

       mdbFontset - Fontset

DESCRIPTION

       The m17n library loads a fontset definition from the m17n database by the tags <fontset, FONTSET-NAME>. The plist format of the data is as
       follows:

       FONTSET ::= PER-SCRIPT * PER-CHARSET * FALLBACK *

       PER-SCRIPT ::= '(' SCRIPT PER-LANGUAGE + ')'

       PER-LANGUAGE ::= '(' LANGUAGE FONT-SPEC-ELEMENT + ')'

       PER-CHARSET ::= '(' CHARSET FONT-SPEC-ELEMENT + ')'

       FALLBACK ::= FONT-SPEC-ELEMENT

       FONT-SPEC-ELEMENT ::= '(' FONT-SPEC [ FLT-NAME ] ')'

       FONT-SPEC ::=
	    '(' [ FOUNDRY FAMILY
		  [ WEIGHT [ STYLE [ STRETCH [ ADSTYLE ]]]]]
		REGISTRY
	     [ OTF-SPEC ] [ LANG-SPEC ] ')'

       SCRIPT is a symbol of script name (e.g. latin, han) or nil. LANGUAGE is a two-letter symbol of language name code defined by ISO 639 (e.g.
       ja, zh) or nil.

       FONT-SPEC is to specify properties of a font. FOUNDRY to REGISTRY are symbols corresponding to Mfoundry to Mregistry property of a font.
       See m17nFont for the meaning of each property.

       OTF-SPEC is a symbol specifyng the required OTF features. The symbol name has the following syntax.

	 OTF-SPEC-NAME ::= ':otf=' SCRIPT LANGSYS ? GSUB-FEATURES ? GPOS-FEATURES ?

	 SCRIPT ::= SYMBOL
	 LANGSYS ::= '/' SYMBOL

	 GSUB-FEATURES ::= '=' FEATURE-LIST ?

	 GPOS-FEATURES ::= '+' FEATURE-LIST ?

	 FEATURE-LIST ::= '~' ? FEATURE ( ',' '~' ? FEATURE ',' )

       Here, FEATURE is a four-letter Open Type feature.

       LANG-SPEC is a symbol specifying the required language support. The symbol name has the following syntax.

	 LANG-SPEC-NAME ::= ':lang=' LANG

       Here, LANG is a two or three-letter ISO-639 language code.

       FLT-NAME is a name of Font Layout Table (Font Layout Table).

EXAMPLE

       This is an example of PER_SCRIPT.

       (han
	 (ja
	   ((jisx0208.1983-0)))
	 (zh
	   ((gb2312.1980-0)))
	 (nil
	   ((big5-0))))

       It instructs the font selector to use a font of registry 'jisx0208.1983-0' for a 'han' character (i.e. a character whose Mscript property
       is 'han') if the character has Mlanguage text property 'ja' in an M-text and the character is in the repertories of such fonts. Otherwise,
       try a font of registry 'gb2312.1980-0' or 'big5-0'. If that 'han' character does not have Mlanguage text property, try all three fonts.

       See the function mdraw_text() for the detail of how a font is selected.

NAME

       mfontset_modify_entry - Modify the contents of a fontset.

SYNOPSIS

       int mfontset_modify_entry (MFontset * fontset, MSymbol script, MSymbol language, MSymbol charset, MFont * spec, MSymbol layouter_name, int
       how)

DESCRIPTION

       Modify the contents of a fontset. The mfontset_modify_entry() function associates, in fontset fontset, a copy of font with the script /
       language pair or with charset.

       Each font in a fontset is associated with a particular script/language pair, with a particular charset, or with the symbol Mnil.  The fonts
       that are associated with the same item make a group.

       If script is not Mnil, it must be a symbol identifying a script. In this case, language is either a symbol identifying a language or Mnil,
       and font is associated with the script / language pair.

       If charset is not Mnil, it must be a symbol representing a charset object. In this case, font is associated with that charset.

       If both script and charset are not Mnil, two copies of font are created. Then one is associated with the script / language pair and the
       other with that charset.

       If both script and charset are Mnil, font is associated with Mnil.  This kind of fonts are called fallback fonts.

       The argument how specifies the priority of font.  If how is positive, font has the highest priority in the group of fonts that are
       associated with the same item. If how is negative, font has the lowest priority. If how is zero, font becomes the only available font for
       the associated item; all the other fonts are removed from the group.

       If layouter_name is not Mnil, it must be a symbol representing a mdbFLT (font layout table). In that case, if font is selected for drawing
       an M-text, that font layout table is used to generate a glyph code sequence from a character sequence.

RETURN VALUE

	   If the operation was successful, mfontset_modify_entry() returns 0. Otherwise it returns -1 and assigns an error code to the external
	   variable merror_code.

ERRORS

	   MERROR_SYMBOL
