davsclaus opened a new pull request, #26565: URL: https://github.com/apache/camel/pull/26565
Fixes https://issues.apache.org/jira/browse/CAMEL-24802 Adds an `escape(kind, exp)` function to the simple language so special characters can be escaped without chaining `replace` calls or writing a bean: ``` ${escape(html)} -> escapes the message body ${escape(xml, ${header.title})} ${escape(json, ${body})} ${escape(js, ${header.msg})} ${escape(sql, ${header.name})} ${escape(url, 'Camel in Action')} -> Camel%20in%20Action ``` - `kind` is one of `html`, `xml`, `json`, `js` (alias `javascript`), `sql`, `url` — case-insensitive, resolved at parse time so an unknown kind fails with a `SimpleParserException` listing the valid kinds - `exp` is optional and defaults to the message body, like the other string functions; only the first comma is used as separator so nested functions with commas work (`${escape(html, ${concat(${body},${body},-)})}`) - `url` uses RFC 3986 component encoding (space → `%20`, not `+`) - Implemented in a new JDK-only `org.apache.camel.util.EscapeHelper` (no new dependency); the escape function itself lives in `StringFunctionFactory` / `StringExpressionBuilder` in camel-core-languages - `@Metadata` on `SimpleConstants` so the function shows up in the catalog, the JS validator and the TUI/MCP function reference (regenerated files included) - Docs: string function table + a new subsection in `simple-functions.adoc` Tests: `EscapeHelperTest` (camel-util) and new cases in `StringFunctionFactoryTest` (camel-core); ran the full `org.apache.camel.language.simple` test package in camel-core (593 tests green). Background: a user asked on Zulip how to escape special characters before feeding data to a Velocity template; the template-side alternative (Velocity `EscapeTool`) was documented separately in b2190cda403a. _Claude Code on behalf of davsclaus_ -- This is an automated message from the Apache Git Service.
