<div class="section" id="header-files-migration">
<span id="header-files"></span><span id="index-0"></span>
<p>In our main operational suite, 9 files, out of 115, need modification, and
118 out of 932, amongst all suites.</p>
<p>Many header files are a snapshot of old versions
of the main header files, used to setup stand alone projects.
This migration can be an opportunity to converge toward a common configuration
file set.</p>
<p>We also found that similar code was replicated amongst multiple files. This
leads to &#8220;code cleaning&#8221; and factorisation.</p>
<ul>
<li><p class="first">We have the main configuration variables defined in our trap.h header file:</p>
<div class="highlight-python"><pre>SMSNODE=%SMSNODE%
SMS_PROG=%SMS_PROG%
SMSNAME=%SMSNAME%
SMSPASS=%SMSPASS%
SMSTRYNO=%SMSTRYNO%
SMSRID=$(echo $QSUB_REQID | cut -f1 -d.)
SMSHOSTFILE=$HOME/.smshostfile
SMSJOBOUT=%SMSJOBOUT%</pre>
</div>
</li>
<li><p class="first">synchronisation commands existed in the rcp.h header:</p>
<div class="highlight-python"><pre>rcp %LOGDIR%%SMSNAME%.%SMSTRYNO%  emos@%SMSNODE%:%SMSOUT%%SMSNAME%.%SMSTRYNO%</pre>
</div>
</li>
<li><p class="first">queuing system directives had embedded SMS vairiable (qsub.h):</p>
<div class="highlight-python"><div class="highlight"><pre><span class="c"># QSUB -o %LOGDIR%%SMSNAME%.%SMSTRYNO%</span>
</pre></div>
</div>
</li>
<li><p class="first">SMS child commands were called in few header files: trap.h
(smsabort, smsinit) and endt.h (smscomplete)</p>
</li>
<li><p class="first">All SMS variable must be used with a default value (%SMSX:0%) to
prevent ecFlow to complain when generating job file.</p>
</li>
<li><p class="first">we can then proceed to variables translation or include specific ecFlow header
files.
