<span class="command"><strong>yaz-asncomp</strong></span> is an ASN.1 compiler that
reads an ASN.1 specification in <em class="replaceable"><code>filename</code></em>
and produces C/C++ definitions and BER encoders/decoders for it.
</p><p>
The produced C/C++ code and header files uses the ODR module of YAZ
which is a library that encodes/decodes/prints BER packages.
<span class="command"><strong>yaz-asncomp</strong></span> allows you to specify name of
resulting source via options. Alternatively, you can specify
a DEFINISIONS file, which provides customized output to
many output files - if the ASN.1 specification file consists
of many modules.
</p><p>
This utility is written in Tcl. Any version of Tcl should work.

The definitions file is really a Tcl script but follows
traditional rules for Shell like configuration files.
That is # denotes the beginning of a comment. Definitions
are line oriented. The definitions files usually consists of
a series of variable assignments of the form:
</p><p>
<code class="literal">set</code> <em class="replaceable"><code>name</code></em> <em class="replaceable"><code>value</code></em>
</p><p>
Available variables are:
</p><div class="variablelist"><dl class="variablelist"><dt><span class="term"><code class="literal">default-prefix</code></span></dt><dd><p>
Sets prefix for names in the produced output.
The value consists of three tokens: C function prefix,
C typedef prefix and preprocessor prefix respectively.
</p></dd><dt><span class="term"><code class="literal">prefix(</code><em class="replaceable"><code>module</code></em><code class="literal">)</code></span></dt><dd><p>
This value sets prefix values for module
<em class="replaceable"><code>module</code></em>.
The value has same form as <code class="literal">default-prefix</code>.
</p></dd><dt><span class="term"><code class="literal">filename(</code><em class="replaceable"><code>module</code></em><code class="literal">)</code></span></dt><dd><p>
Specifies filename for C/header file for module
<em class="replaceable"><code>module</code></em>.
</p></dd><dt><span class="term"><code class="literal">init(</code><em class="replaceable"><code>module</code></em><code class="literal">,h)</code></span></dt><dd><p>

</p></dd><dt><span class="term"><code class="literal">init(</code><em class="replaceable"><code>module</code></em><code class="literal">,c)</code></span></dt><dd><p>

</p></dd><dt><span class="term"><code class="literal">body(</code><em class="replaceable"><code>module</code></em><code class="literal">,c)</code></span></dt><dd><p>

Maps ASN.1 type in module <em class="replaceable"><code>module</code></em>
of <em class="replaceable"><code>name</code></em> to value.
</p></dd><dt><span class="term"><code class="literal">membermap(</code><em class="replaceable"><code>module</code></em><code class="literal">,</code><em class="replaceable"><code>name</code></em><code class="literal">,</code><em class="replaceable"><code>member</code></em><code class="literal">)</code></span></dt><dd><p>
Maps member <em class="replaceable"><code>member</code></em> in SEQUENCE/CHOICE of
<em class="replaceable"><code>name</code></em> in module
<em class="replaceable"><code>module</code></em> to value.
The value consists of one or two tokens.
First token is name of C preprocessor part. Second token
is resulting C member name. If second token is omitted
the value (one token) is both preprocessor part and
C <code class="literal">struct</code>,<code class="literal">union</code>.
</p></dd><dt><span class="term"><code class="literal">unionmap(</code><em class="replaceable"><code>module</code></em><code class="literal">,</code><em class="replaceable"><code>name</code></em><code class="literal">,</code><em class="replaceable"><code>member</code></em><code class="literal">)</code></span></dt><dd><p>
Maps member <em class="replaceable"><code>member</code></em> in CHOICE of
<em class="replaceable"><code>name</code></em> in module
<em class="replaceable"><code>module</code></em> to value.
Value consists of to or three tokens. The first token
is name of the integer in the <code class="literal">union</code> that
is used as selector for the <code class="literal">union</code> itself.
The second token is name of the <code class="literal">union</code>.
The third token overrides the name of the CHOICE member;
if omitted the member name is used.
