<h2>Integrating Duktape into your program</h2> |
|
|
|
|
|
|
|
<p>The command line tool is simply an example of a program which embeds |
|
|
|
Duktape. Embedding Duktape into your program is very simple: just add |
|
|
|
<code>duktape.c</code>, <code>duktape.h</code>, and <code>duk_config.h</code> |
|
|
|
to your build, and call the Duktape API from elsewhere in your program.</p> |

Duktape. Embedding Duktape into your program is very simple:</p> |
|
|
|
|
|
|
|
<ul> |
|
|
|
<li>Run <code>duktape-N.N.N/tools/configure.py</code> to configure Duktape |
|
|
|
for build. The result is a directory containing <code>duktape.c</code>, |
|
|
|
<code>duktape.h</code>, and <code>duk_config.h</code>.</li> |
|
|
|
<li>Add <code>duktape.c</code>, <code>duktape.h</code>, and <code>duk_config.h</code> |
|
|
|
to your build, and call the Duktape API from elsewhere in your program.</li> |
|
|
|
</ul> |
|
|
|
|
|
|
|
<p>The Duktape distributable (duktape-N.N.N.tar.xz) <code>src/</code> directory |
|
|
|
contains preconfigured header and source files for the Duktape default configuration |
|
|
|
which can usually be used as is. If needed, the configuration tool allows you to customize |
|
|
|
Duktape options, such as optimizing Duktape for low memory targets and |
|
|
|
enable/disable features. See <a href="#compiling">Compiling</a> and |
|
|
|
<a href="http://wiki.duktape.org/Configuring.html">Configuring Duktape for build</a> |
|
|
|
for more details and examples.</p> |
|
|
|
|
|
|
|
<p>The distributable contains a very simple example program, <code>hello.c</code>, |
|
|
|
which illustrates this process. Compile the test program e.g. as (see |
|
|
|
<a href="#compiling">Compiling</a> for compiler option suggestions):</p> |
|
|
|
which illustrates this process. Compile the test program with the preconfigured |
|
|
|
Duktape header and source files e.g. as follows:</p> |
|
|
|
<pre> |
|
|
|
$ cd /tmp/duktape-<version>/ |
|
|
|
$ gcc -std=c99 -o hello -Isrc src/duktape.c examples/hello/hello.c -lm |
|
|
|
</pre> |
|
|
|
|
|
|
|
<p>To customize Duktape configuration use <code>configure.py</code>:</p> |
|
|
|
<pre> |
|
|
|
$ cd /tmp/duktape-<version>/ |
|
|
|
$ gcc -std=c99 -o hello -Isrc/ src/duktape.c examples/hello/hello.c -lm |
|
|
|
# Here we disable Ecmascript 6 Proxy object support |
|
|
|
$ python2 tools/configure.py --output-directory duktape-src -UDUK_USE_ES6_PROXY |
|
|
|
$ gcc -std=c99 -o hello -Iduktape-src duktape-src/duktape.c examples/hello/hello.c -lm |
|
|
|
</pre> |
