《编写可维护的 JavaScript》读书笔记第16章：文件合并和加工

1. 文件合并

<tstamp>
<format property="build.time" pattern="yyyy-MM-dd hh:mm:ss"/>
</tstamp>
<target name="concatenate">
<concat destfile="${build.src}/build.js" fixlastline="yes" eol="lf" encoding="utf-8">
<header>/* Build Time: ${build.time} */</header>
<filelist dir="${src.dir}" files="first.js,second.js"/>
<fileset dir="${src.dir}" includes="**/*.js" excludes="first.js,second.js"/>
<footer trimleading="yes">
/* footer */
</footer>
</concat>
</target>

2. 加工文件

2.1 插入 license 文件

<target name="concatenate">
<loadfile property="license" srcfile="license.txt"/>
<concat destfile="${build.src}/build.js" fixlastline="yes" eol="lf">
<header trimleading="yes">/*!
${license}
*/
/* Build Time: ${build.time} */
</header>
<filelist .../>
<fileset .../>
</concat>
</target>

2.2 替换字符串

var MyProject = {
version: "@VERSION@"
};

<target name="concatenate">
<concat destfile="${build.src}/build.js" fixlastline="yes" eol="lf">
<filelist .../>
<fileset .../>

<replaceregexp match="@VERSION@" replace="${version}" flags="g" byline="true" encoding="utf-8">
<fileset dir="${build.dir}" includes="**/*"/>
</replaceregexp>
</concat>
</target>
