<p><font face="Verdana"><font size=-1>HTMLGen is a C++ text-processing
|
||
|
|
utility that lets users quickly generate HTML testcases. While HTMLGen
|
||
|
|
is not restricted to generating HTML files, the program does understand
|
||
|
|
the set of known HTML tags. HTMLGen takes user supplied file fragments
|
||
|
|
and command line arguments as input, and automatically generates a series
|
||
|
|
of derived HTML files.</font></font>
|
||
|
|
<p><font face="Verdana"><font size=-1>Here's a quick example: Let's say
|
||
|
|
you want to create a series of tests to verify that Gecko correctly renders
|
||
|
|
every tag inside the <BODY> element. To accomplish this, begin with
|
||
|
|
a small HTML fragment file given below:</font></font>

<table COLS=1 WIDTH="30%" BGCOLOR="#CCCCCC" >

|

</table>
|
||
|
|
|
||
|
|
<p><font face="Verdana"><font size=-1>Notice that the file looks like a
|
||
|
|
typical HTML file, except for the tags that read <$0> and </$0>.
|
||
|
|
These are macros, which are content that will be replaced by arguments
|
||
|
|
provided on the HTMLGen command line. To finish our example, simply run
|
||
|
|
HTMLGen with the following command line arguments:</font></font>
|
||
|
|
<pre><tt><font color="#3333FF">HTMLGen -f test1.html a-z</font></tt></pre>
|
||
|
|
<font face="Verdana"><font size=-1>This instructs HTML to read the test1.html
|
||
|
|
file and use it as a template. Next, the tag-range argument "a-z" instructs
|
||
|
|
HTMLGen to autogenerate a file for each HTML tag between A and Z. HTMLGen
|
||
|
|
uses this argument as the 0th element of its macro substitution process.
|
||
|
|
The macros <$0> and </$0> will be replaced in each autogenerated
|
||
|
|
file with the current value of the $0 argument. So, the first file will
|
||
|
|
contain <A> where it sees <$0>, the second will use <B> and so
|
||
|
|
on.</font></font>
|
||
|
|
<p><font face="Verdana"><font size=-1>The result of running HTMLGen against
|
||
|
|
the given template with these arguments is that you'll get a new file for
|
||
|
|
each tag we see in the range between A..Z. Note that in this example
|
||
|
|
we're emitting valid HTML, but that is not a requirement. You can use HTMLGen
|
||
|
|
to generate lots of illegal content for testing as well.</font></font>
