<h1>5. cdist-hacker(7)<a class="headerlink" href="#cdist-hacker-7" title="Permalink to this headline"></a></h1>
<p>How to get (stuff) into cdist</p>
<p>Nico Schottelius &lt;<a class="reference external" href="mailto:nico-cdist--&#37;&#52;&#48;--schottelius&#46;org">nico-cdist--<span>&#64;</span>--schottelius<span>&#46;</span>org</a>&gt;</p>
<div class="section" id="welcome">
<h2>5.1. WELCOME<a class="headerlink" href="#welcome" title="Permalink to this headline"></a></h2>
<p>Welcome dear hacker! I invite you to a tour of pointers to
get into the usable configuration mangament system, cdist.</p>
<p>The first thing to know is probably that cdist is brought to
you by people who care about how code looks like and who think
twice before merging or implementing a feature: Less features
with good usability are far better than the opposite.</p>
</div>
<div class="section" id="reporting-bugs">
<h2>5.2. REPORTING BUGS<a class="headerlink" href="#reporting-bugs" title="Permalink to this headline"></a></h2>
<p>If you believe you&#8217;ve found a bug and verified that it is
in the latest version, drop a mail to the cdist mailing list,
subject prefixed with &#8220;[BUG] &#8221; or create an issue on github.</p>
</div>
<div class="section" id="coding-conventions-everywhere">
<h2>5.3. CODING CONVENTIONS (EVERYWHERE)<a class="headerlink" href="#coding-conventions-everywhere" title="Permalink to this headline"></a></h2>
<p>If something should be better done or needs to fixed, add the word FIXME
nearby, so grepping for FIXME gives all positions that need to be fixed.</p>
<p>Indention is 4 spaces (welcome to the python world).</p>
</div>
<div class="section" id="how-to-submit-stuff-for-inclusion-into-upstream-cdist">
<h2>5.4. HOW TO SUBMIT STUFF FOR INCLUSION INTO UPSTREAM CDIST<a class="headerlink" href="#how-to-submit-stuff-for-inclusion-into-upstream-cdist" title="Permalink to this headline"></a></h2>
<p>If you did some cool changes to cdist, which you value as a benefit for
everybody using cdist, you&#8217;re welcome to propose inclusion into upstream.</p>
<p>There are though some requirements to ensure your changes don&#8217;t break others
work nor kill the authors brain:</p>
<ul>
<li><p class="first">All files should contain the usual header (Author, Copying, etc.)</p>
</li>
<li><p class="first">Code submission must be done via git</p>
</li>
<li><p class="first">Do not add cdist/conf/manifest/init - This file should only be touched in your
private branch!</p>
</li>
<li><p class="first">Code to be included should be branched of the upstream &#8220;master&#8221; branch</p>
<blockquote>
<div><ul class="simple">
<li>Exception: Bugfixes to a version branch</li>
</ul>
</div></blockquote>
</li>
<li><p class="first">On a merge request, always name the branch I should pull from</p>
</li>
<li><p class="first">Always ensure <strong>all</strong> manpages build. Use <strong>./build man</strong> to test.</p>
</li>
<li><p class="first">If you developed more than <strong>one</strong> feature, consider submitting them in
separate branches. This way one feature can already be included, even if
the other needs to be improved.</p>
</li>
</ul>
<p>As soon as your work meets these requirements, write a mail
for inclusion to the mailinglist <strong>cdist at cdist &#8211; at &#8211; l.schottelius.org</strong>
or open a pull request at <a class="reference external" href="http://github.com/telmich/cdist">http://github.com/telmich/cdist</a>.</p>
</div>
<div class="section" id="how-to-submit-a-new-type">
<h2>5.5. HOW TO SUBMIT A NEW TYPE<a class="headerlink" href="#how-to-submit-a-new-type" title="Permalink to this headline"></a></h2>
<p>For detailled information about types, see cdist-type(7).</p>
<p>Submitting a type works as described above, with the additional requirement
that a corresponding manpage named man.text in asciidoc format with
the manpage-name &#8220;cdist-type__NAME&#8221; is included in the type directory
AND asciidoc is able to compile it (i.e. do NOT have to many &#8220;=&#8221; in the second
line).</p>
<p>Warning: Submitting &#8220;exec&#8221; or &#8220;run&#8221; types that simply echo their parameter in
<strong>gencode</strong> will not be accepted, because they are of no use. Every type can output
code and thus such a type introduces redundant functionality that is given by
core cdist already.</p>

<span class="n">git</span> <span class="n">merge</span> <span class="n">origin</span><span class="o">/</span><span class="n">master</span>
</pre></div>
</div>
<p>If at any point you want to go back to the original master branch, you can
use <strong>git stash</strong> to stash your changes away:</p>
<div class="highlight-default"><div class="highlight"><pre><span></span><span class="c1"># assume you are on documentation_cleanup</span>
<span class="n">git</span> <span class="n">stash</span>
<span class="c1"># change to master and update to most recent upstream version</span>
<span class="n">git</span> <span class="n">checkout</span> <span class="n">master</span>
<span class="n">git</span> <span class="n">fetch</span> <span class="o">-</span><span class="n">v</span> <span class="n">origin</span>
<span class="n">git</span> <span class="n">merge</span> <span class="n">origin</span><span class="o">/</span><span class="n">master</span>
</pre></div>
</div>
<p>Similar when you want to develop another new feature, you go back
to the master branch and create another branch based on it:</p>
<div class="highlight-default"><div class="highlight"><pre><span></span><span class="c1"># change to master and update to most recent upstream version</span>
<span class="n">git</span> <span class="n">checkout</span> <span class="n">master</span>
<span class="n">git</span> <span class="n">fetch</span> <span class="o">-</span><span class="n">v</span> <span class="n">origin</span>
<span class="n">git</span> <span class="n">merge</span> <span class="n">origin</span><span class="o">/</span><span class="n">master</span>
<span class="n">git</span> <span class="n">checkout</span> <span class="o">-</span><span class="n">b</span> <span class="n">another_feature</span>
</pre></div>
</div>
<p>(you can repeat the code above for as many features as you want to develop
in parallel)</p>
