commit eca564db9eeed97d21d532c6966c0289100fc594 Author: Cole Greer <[email protected]> AuthorDate: Thu May 21 17:05:16 2026 -0700 Add CodeRay syntax highlighting via JRuby Use the CodeRay gem bundled with AsciidoctorJ to highlight generated code content in tabs. The JRuby runtime is accessed via JRubyRuntimeContext to call CodeRay::Duo directly, producing the same highlighted HTML spans as regular source blocks. Falls back to plain HTML escaping if CodeRay is unavailable. --- .../gremlin/docs/GremlinTreeprocessor.java | 38 ++++++++++++++++++++-- .../tinkerpop/gremlin/docs/TabbedHtmlBuilder.java | 26 ++++++++++++++- .../gremlin/docs/GremlinTreeprocessorTest.java | 6 ++-- .../tinkerpop/gremlin/docs/IntegrationTest.java | 10 +++--- 4 files changed, 68 insertions(+), 12 deletions(-) diff --git a/tools/tinkerpop-docs/src/main/java/org/apache/tinkerpop/gremlin/docs/GremlinTreeprocessor.java b/tools/tinkerpop-docs/src/main/java/org/apache/tinkerpop/gremlin/docs/GremlinTreeprocessor.java index 34b40a11c6..ef2d4827ae 100644 --- a/tools/tinkerpop-docs/src/main/java/org/apache/tinkerpop/gremlin/docs/GremlinTreeprocessor.java +++ b/tools/tinkerpop-docs/src/main/java/org/apache/tinkerpop/gremlin/docs/GremlinTreeprocessor.java @@ -242,9 +242,11 @@ public class GremlinTreeprocessor extends Treeprocessor { final String consoleOutput = buildConsoleOutput(gremlinBlock, dryRun); final List<TabbedHtmlBuilder.Tab> tabs = new ArrayList<>(); - tabs.add(TabbedHtmlBuilder.consoleTab("groovy", consoleOutput)); + tabs.add(TabbedHtmlBuilder.consoleTabHighlighted("groovy", + highlightAsGroovy(parent, consoleOutput))); // Add second tab with clean source code (no prompts/output) - tabs.add(TabbedHtmlBuilder.codeTab("groovy", gremlinBlock.getSource())); + tabs.add(TabbedHtmlBuilder.codeTabHighlighted("groovy", + highlightAsGroovy(parent, gremlinBlock.getSource()))); // Consume consecutive [source,<lang>] sibling blocks as manual tabs (FR-5) int lastIndex = startIndex; @@ -253,7 +255,8 @@ public class GremlinTreeprocessor extends Treeprocessor { if (isManualTabBlock(sibling)) { final Block sourceBlock = (Block) sibling; final String lang = getSourceLanguage(sourceBlock); - tabs.add(TabbedHtmlBuilder.codeTab(lang, sourceBlock.getSource())); + tabs.add(TabbedHtmlBuilder.codeTabHighlighted(lang, + highlightAsSource(parent, lang, sourceBlock.getSource()))); lastIndex = j; } else { break; @@ -265,6 +268,35 @@ public class GremlinTreeprocessor extends Treeprocessor { return startIndex; } + /** + * Highlights source code using CodeRay via the JRuby runtime bundled with AsciidoctorJ. + */ + private String highlightAsGroovy(final StructuralNode parent, final String source) { + return highlightAsSource(parent, "groovy", source); + } + + private String highlightAsSource(final StructuralNode parent, final String lang, final String source) { + if (source == null || source.isEmpty()) return ""; + try { + final org.jruby.Ruby ruby = org.asciidoctor.jruby.internal.JRubyRuntimeContext.get(parent); + if (ruby == null) return escapeHtml(source); + ruby.evalScriptlet("require 'coderay' unless defined?(CodeRay)"); + final String escaped = source.replace("\\", "\\\\").replace("'", "\\'"); + final String script = "CodeRay::Duo[:" + lang + ", :html, :css => :class].highlight('" + escaped + "')"; + final org.jruby.runtime.builtin.IRubyObject result = ruby.evalScriptlet(script); + return result != null ?
