Bug: Missing Semicolon in output Parameter Breaks XQuery Execution

[allanc007]

🐛

Description

When executing an XQuery script from VS Code using CTRL + ALT + ENTER, the request sent to the eXist-db Atom Editor endpoint fails unless the output parameter ends with a semicolon (;).

The plugin correctly extracts the serialization method (e.g., "xml"), but the Atom Editor endpoint requires:

output=xml;

Without the trailing semicolon, the query execution fails.

Environment

VS Code

eXist-db (tested with 7.0.0-SNAPSHOT)

Multi-workspace setup

Endpoint:

/exist/apps/atom-editor/execute
Steps to Reproduce

Open an .xql file in VS Code.

Include serialization options such as:

declare option output:method "xml";

Press CTRL + ALT + ENTER.

Observe failed execution unless output includes a trailing semicolon.

        const queryTime = response.headers['x-elapsed'];

        const queryResponse = {
            output: params.output,
            hits: resultCount,
            elapsed: queryTime,
            results: response.data
        };

        return queryResponse;
    })
    .catch(error => {
        this.logger(`Query execution failed: ${JSON.stringify(error)}`, 'error');
        throw error;
    });

I cheated by: (by doing some string concatenation).

	private getOutputMode(content: string) {
		const match = /declare\s+option.*:method\s+"(.*)"\s*;/.exec(content);
		if (match) {
			return match[1] + ';';
		}
		return 'adaptive' + ';';
	}

Nice to see the returned output next to my code window.
