<a class=btn style=color:#fff;background-color:OrangeRed href=https://www.gitlab.com/moussaelianarsen/advmake><span class=iconify data-icon=fa-brands:gitlab></span> AdvMake</a></p><h2 id=format>Format<a href=#format class=anchor aria-hidden=true>#</a></h2><p>AdvMake uses <a href=https://github.com/bazelbuild/starlark>Starlark</a> as the format for its build files.
|
|
Modules are also defined for both convenience and extra functionality.</p><p>Starlark is a Python-like language meant for configuration files.</p><h2 id=configuration>Configuration<a href=#configuration class=anchor aria-hidden=true>#</a></h2><p>Build files are by default called <code>AdvMakefile</code>, but that can be set via <code>-f</code></p><p>An AdvMakefile example can be found at AdvMake’s repo as it uses AdvMake itself.</p><p>AdvMake runs functions exposed by starlark in the format <code><name>_<target></code>.
|
|
To set the default name and target, the global variables <code>defaultName</code>, and <code>defaultTarget</code> must be set.
|
|
Here is an example from AdvMake’s AdvMakefile:</p><div class=highlight><pre class=chroma><code class=language-python data-lang=python><span class=n>defaultName</span> <span class=o>=</span> <span class=s2>"advmake"</span>
|
|
<span class=n>defaultTarget</span> <span class=o>=</span> <span class=s2>"build"</span>
|
|
</code></pre></div><p>This will tell AdvMake to run the function <code>advmake_build()</code> when run with no arguments.</p><p>If AdvMake is run with one argument (such as <code>advmake install</code>), it will use the default name with the specified target,
|
|
so in that case, it would run <code>advmake_install()</code>.</p><p>If run with two arguments, AdvMake will use the first argument as the name and the second as the target.
|
|
So, running <code>advmake hello world</code> would run the function <code>hello_world()</code>.</p><h2 id=modules>Modules<a href=#modules class=anchor aria-hidden=true>#</a></h2><p>As previously mentioned, AdvMake comes with modules. Those are as follows:</p><h3 id=runtime><code>runtime</code><a href=#runtime class=anchor aria-hidden=true>#</a></h3><p>The runtime module exposes some of golang’s runtime methods and variables.</p><hr><h4 id=runtimegoos><code>runtime.GOOS</code><a href=#runtimegoos class=anchor aria-hidden=true>#</a></h4><p>Stores a string denoting the operating system being used.</p><a class=btn style=color:#fff;background-color:#00acd7 href=https://pkg.go.dev/runtime#GOOS><span class="iconify icon:cib:go"></span>
