日复一日emerge: 中文docbook转换成PDF终于实现

终于搞定了～～～

首先安装fop

# autounmask dev-java/fop-0.94-r1
据说fop对中文的断行支持得比0.93好。另外"zh_cn"也可以正确处理了。
# emerge fop -av

然后生成字体描述文件

# java -cp /usr/share/fop/lib/fop.jar:/usr/share/avalon-framework-4.2/lib/avalon-framework.jar:/usr/share/commons-logging/lib/commons-logging.jar:/usr/share/commons-io-1/lib/commons-io.jar org.apache.fop.fonts.apps.TTFReader /usr/share/fonts/fireflysung/fireflysung.ttf fireflysung.xml

# mkdir /etc/fop
# mv *.xml /etc/fop

建立FOP配置文件

# cp /usr/share/doc/fop-0.94-r1/examples/conf/fop.xconf /etc/fop
# cd /etc/fop

建立zhfop.conf的内容如下：

<?xml version="1.0"?>
<fop version="1.0">
 <base>.</base>
  <renderers>
   <renderer mime="application/pdf">
      <filterList>
        <value>flate</value>
    </filterList>
     <fonts>  
       <font metrics-url="/etc/fop/simsun.xml" kerning="yes"
 embed-url="/usr/share/fonts/winfonts/simsun.ttf">
             <font-triplet name="SimSun" style="normal" weight="normal"/>
         <font-triplet name="SimSun" style="normal" weight="bold"/>
         <font-triplet name="SimSun" style="italic" weight="normal"/>
           <font-triplet name="SimSun" style="italic" weight="bold"/>
       </font> 
     </fonts>
   </renderer>
 </renderers>
</fop>

创建xsl文件

# cat /usr/share/sgml/docbook/xsl-stylesheets/fo/docbookzhcn.xsl
<?xml version='1.0'?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:fo="http://www.w3.org/1999/XSL/Format"
xmlns:doc="http://nwalsh.com/xsl/documentation/1.0"
exclude-result-prefixes="doc"
version="1.0">
<xsl:import href="docbook.xsl"/>
<xsl:param name="body.font.family">SimSun</xsl:param>
<xsl:param name="body.font.size">12</xsl:param>
<xsl:param name="monospace.font.family">SimSun</xsl:param>
<xsl:param name="title.font.family">SimSun</xsl:param>
<xsl:param name="page.margin.inner">2cm</xsl:param>
<xsl:param name="page.margin.outer">2cm</xsl:param>
<xsl:param name="hyphenate">false</xsl:param>
<xsl:param name="paper.type" select="'A4'"/>
<xsl:param name="draft.mode" select="'no'"/>
</xsl:stylesheet>

用xsltproc来生成HTML或者XSL-FO文件

譬如，下面是根据Docbook文档生成HTML的例子：
$ xsltproc --output myfile.html /usr/share/sgml/docbook/xsl-stylesheets/html/docbook.xsl myfile.xml

或者根据docbook文档生成XSL-FO文档的例子：
$ xsltproc --output myfile.fo /usr/share/sgml/docbook/xsl-stylesheets/fo/docbook.xsl myfile.xml
