<h1 id="introduction">Introduction<a class="headerlink" href="#introduction" title="Permalink">&para;</a></h1>
<p>The Gora compiler-cli is a simple utility dependency which provides a command line interface used to invoke the <a href="./compiler.html">Gora Compiler</a>
It exists separate from the Gora Compiler enabling us to distinguish between usability and functionality. It does however depend upon the Gora Compiler.</p>
<p>The compiler-cli is trivial to invoke but also provides a useful usage statement when invoked incorrectly</p>
<h1 id="usage">Usage<a class="headerlink" href="#usage" title="Permalink">&para;</a></h1>
<pre><code> $ Usage: GoraCompilerCLI
or
$ Uage: GoraCompilerCLI -h
</code></pre>
<p>results in:</p>
<pre><code> $ Usage: gora-compiler ( -h | --help ) | (&lt;input&gt; [&lt;input&gt;...] &lt;output&gt;)
</code></pre>
<p>so for example, if you wished to compile one schema file, you could enter:</p>
<pre><code> $ bin/gora gora-compiler gora-tutorial/src/main/avro/pageview.json gora-tutorial/src/main/java/
</code></pre>
<p>if however for example you wished to compile more than one schema file, you could enter:</p>
<pre><code> $ bin/gora gora-compiler gora-tutorial/src/main/avro/pageview.json gora-core/src/examples/avro/webpage.json gora-tutorial/src/main/avro/metricdatum.json gora-tutorial/src/main/java/
</code></pre>
<p>The schema file is a single JSON file or a string array of JSON files.</p>
<p>The output directory is the destination for the generated Java source files. For example, if you specific <code>src/main/java</code> then the
generate source is placed into <code>src/main/java/</code> under the package naming convention used within the JSON schema.</p>
