The power of Clojure and Java is available to YAMLScript users via the YAMLScript runtime interpreter, <code>ys</code>. However, the <code>ys</code> command is compiled into a single standalone native binary executable file. This means that <u>No Java or JVM</u> installation is required to use YAMLScript, and startup/execution speed is very fast.</p><p>YAMLScript also produces the <code>libyamlscript.so</code> shared library.

YAMLScript lets you include data from external files and other sources, make use of hundreds of existing standard functions, and even define your own variables and functions. You can filter, map, merge, reduce, generate, concatenate, interpolate and manipulate your data as you wish. YAMLScript provides these things with syntax that is minimal and unobtrusive, keeping your clean YAML data clean.</p><blockquote><p>Slides and information from Ingy's <a href="https://www.youtube.com/watch?v=Cdi3Q4Wrt48">KubeCon 2024 talk</a> are available <a href="https://yamlscript.org/kubeys24">here</a>. The highlight was <a href="https://github.com/kubeys/helmys">HelmYS</a> a new Helm post-renderer that lets you template Helm charts with YAMLScript (which is actual YAML).</p></blockquote><p>Like many new languages, YAMLScript was built over an existing robust language, <a href="https://clojure.org">Clojure</a>, which in turn was built over <a href="https://java.com">Java</a>. The power of Clojure and Java is available to YAMLScript users via the YAMLScript runtime interpreter, <code>ys</code>. However, the <code>ys</code> command is compiled into a single standalone native binary executable file. This means that <u>No Java or JVM</u> installation is required to use YAMLScript, and startup/execution speed is very fast.</p><p>YAMLScript also produces the <code>libyamlscript.so</code> shared library. It has <a href="/doc/bindings">binding modules for 10 programming languages</a> including Go, JavaScript, Python and Rust, with many more on the way. These modules can be used in your programs to load normal YAML files as well as YAMLScript enhanced ones.</p><p>There are many ways to use YAMLScript:</p><ul><li>Simplify your existing YAML configs<ul><li>Works great with CI/CD, Helm, Docker, Ansible, etc.</li><li>Check out <a href="https://github.com/kubeys/helmys">HelmYS</a>, a tool for using YAMLScript in Kubernetes Helm chart templates painlessly.</li></ul></li><li><a href="doc/bindings">Load YAMLScript (or YAML) in your programs</a><ul><li>Available in 10 programming languages (and counting)</li></ul></li><li>Program in YAMLScript<ul><li>Learn how at <a href="https://exercism.org/tracks/yamlscript">Exercism</a></li></ul></li><li><a href="doc/examples">Script Automation with YAMLScript</a><ul><li>Many used in the <a href="https://github.com/yaml/yamlscript">YAMLScript repository</a></li></ul></li><li><a href="doc/binary">Compile YAMLScript to binary executables</a><ul><li>Fast, standalone, no-source software distribution</li></ul></li><li><a href="doc/query">Query and Transform YAML (and JSON) data</a><ul><li>Use the <code>ys</code> command line tool similar to <code>jq</code> or <code>yq</code></li></ul></li></ul><hr><h2>YAMLScript Resources</h2><ul><li><a href="https://yamlscript.org">Web Site</a></li><li><a href="https://yamlscript.org/doc">Documentation</a></li><li><a href="https://matrix.to/#/#chat-yamlscript:yaml.io">Matrix Chat</a></li><li><a href="https://clojurians.slack.com/archives/yamlscript">Slack Chat</a></li><li><a href="https://yamlscript.org/blog">Blog</a></li><li><a href="https://github.com/yaml/yamlscript">GitHub Repository</a></li><li><a href="https://github.com/yaml/yamlscript/discussions">Discussions</a></li><li><a href="https://github.com/yaml/yamlscript/issues">Issues</a></li></ul><hr><h2>YAMLScript Links</h2><ul><li>Nov 2024 <a href="https://yamlscript.org/kubeys24">KubeCon Talk and Info</a></li><li>Jun 2024 <a href="https://www.youtube.com/watch?v=RFIukRdFe1o">TPRC Talk</a></li><li>Apr 2024 <a href="https://www.youtube.com/watch?v=u-OCEHNdwlU">OSS/NA Talk</a></li><li>Mar 2024 <a href="https://thenewstack.io/with-yamlscript-yaml-becomes-a-proper-programming-language/">TheNewStack Article</a></li><li>Mar 2024 <a href="https://www.youtube.com/watch?v=GajOBwBcFyA">Seajure Talk</a></li></ul><hr></div><ul class="hero__social-links"></ul></div></header><section class="post-list__wrapper"><h2 class="post-list__heading">Recent Posts</h2><ul class="post-list"><li class="post-list__item"><div><div class="post-list__meta"><time datetime="2024-11-29">29 Nov 2024 </time><span>| </span><span>7 min read</span></div><div class="post-list__tags"><a href="/tags/blog/">#blog</a></div></div><h3 class="post-list__title"><a href="/posts/2024-11-29/">The Kubernetes Effect</a></h3><p class="post-list__excerpt">In my many years of creating Open Source software and talking about it at conferences, some of the most productive development times are often those leading up to the presentation.

We aliased nodes that were anchored in a different document. What's up?</p><p>Well, the two YAMLScript documents each have a different <a href="https://yamlscript.org/doc/modes">YAMLScript mode</a> and that makes things work differently.</p><p>The first document has no <code>!yamlscript/v0</code> tag and thus is in &quot;bare mode&quot;. In bare mode all the rules are the same as YAML 1.2 (using the Core schema).</p><p>The second document has the <code>!yamlscript/v0:</code> tag. The <code>!yamlscript/v0</code> tag tells YAMLScript that the document is in &quot;code mode&quot; (the content starts as code but can switch to data mode at any time). The <code>:</code> in <code>!yamlscript/v0:</code> tells YAMLScript to switch to data mode right away.</p><p>In code mode and data mode, aliases are very different than in bare mode. They can access anchored nodes in the same document or any previous document. Not only that, you can access parts of the anchored node with a path syntax. For instance <code>*map1.name</code> would produce the string &quot;Bobbi Datamon&quot; and <code>*list1.1</code> would produce the string &quot;games&quot;.</p><p>That means that this works the same way as the previous example:</p><pre class="language-yaml"><code class="language-yaml"><span class="token punctuation">---</span> <span class="token important">&amp;data</span><br><span class="token key atrule">map1</span><span class="token punctuation">:</span><br>  <span class="token key atrule">name</span><span class="token punctuation">:</span> Bobbi Datamon<br><span class="token key atrule">list1</span><span class="token punctuation">:</span><br><span class="token punctuation">-</span> fun<br><span class="token punctuation">-</span> games<br><span class="token key atrule">more</span><span class="token punctuation">:</span> stuff<br><br><span class="token key atrule">--- !yamlscript/v0</span><span class="token punctuation">:</span><br><span class="token key atrule">person</span><span class="token punctuation">:</span><br>  &lt;&lt;<span class="token punctuation">:</span><span class="token punctuation">:</span> <span class="token punctuation">-</span><span class="token important">*data.map1</span><br>  likes<span class="token punctuation">:</span><span class="token punctuation">:</span> <span class="token punctuation">-</span><span class="token important">*data.list1</span></code></pre><p>Here we only anchored the entire first document and then used the path syntax to access the parts we wanted.
