> -------------------------------------------------

> Key: GROOVY-11314
> URL: https://issues.apache.org/jira/browse/GROOVY-11314
> Project: Groovy
> Issue Type: Bug
> Components: JSON
> Affects Versions: 2.5.23, 3.0.20, 4.0.18
> Reporter: Denis Jakupovic
> Priority: Major
>
> Hi,
> the groovy.json package is widely used.
> [https://github.com/apache/groovy/blob/master/subprojects/groovy-json/src/main/java/groovy/json/JsonOutput.java]
>
> If we use the toPrettyString function the json is being escaped.
> {code:java}
> JsonBuilder Class:
> public String toPrettyString() {
> return JsonOutput.prettyPrint(toString());
> } {code}
> However, we can construct a JsonBuilder with JsonGenerator and
> disableUnicodeEscaping, this is not possible with JsonOutput though because
> there is a final constructor. However it is true in default. It would be
> great if the JsonOutput had the same feature to construct JsonOutput with a
> custom JsonGenerator. The JsonOutput object uses the DefaultJsonGenerator
> with enabled unicode escaping through Options.
> [https://github.com/apache/groovy/blob/GROOVY_3_0_X/subprojects/groovy-json/src/main/java/groovy/json/JsonOutput.java#L209|https://github.com/apache/groovy/blob/GROOVY_3_0_X/subprojects/groovy-json/src/main/java/groovy/json/JsonOutput.java#L162]
> {code:java}
> case STRING:
> String textStr = token.getText();
> String textWithoutQuotes = textStr.substring(1, textStr.length() - 1);
> if (textWithoutQuotes.length() > 0) {
> output.addJsonEscapedString(textWithoutQuotes);
> } else {
> output.addQuoted(Chr.array());
> }
> break; {code}
> And here:
> [https://github.com/apache/groovy/blob/master/subprojects/groovy-json/src/main/java/org/apache/groovy/json/internal/CharBuf.java#L379]
> {code:java}
> public final CharBuf addJsonEscapedString(final char[] charArray, boolean
> disableUnicodeEscaping) {
> if (charArray.length == 0) return this;
> if (hasAnyJSONControlChars(charArray, disableUnicodeEscaping)) {
> return doAddJsonEscapedString(charArray, disableUnicodeEscaping);
> } else {
> return this.addQuoted(charArray);
> }
> } {code}
> *If the JsonBuilder is constructed with a JsonGenerator it should be
> constructed with JsonOuput as well and the prettyPrint function shall not add
> escaped strings.* *The Bug is in JsonOutput.*
> This has to be fixed:
> {code:java}
> case STRING:
> String textStr = token.getText();
> String textWithoutQuotes = textStr.substring(1,
> textStr.length() - 1);
> if (textWithoutQuotes.length() > 0) {
> output.addJsonEscapedString(textWithoutQuotes,
> disableUnicodeEscaping);
> } else {
> output.addQuoted(Chr.array());
> } break; {code}
> output.addJsonEscapedString(textWithoutQuotes, disableUnicodeEscaping) should
> be called with disableUnicodeEscaping.
> Currently there is no way to prettyPrint a json with the groovy.json classes
> without having escaped characters in the generated json.
> Best
