Denis Jakupovic commented on GROOVY-11314:
------------------------------------------
Yes absolutely! This is my wished approach and would not break any other code.
Thank you Paul!
So what do you think? Will this make it to public release soon?

> JsonOutput Pretty Print always escapes characters

> Key: GROOVY-11314
> URL: https://issues.apache.org/jira/browse/GROOVY-11314
> Project: Groovy
> Issue Type: Wish
> 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 and use new JsonBuilder(content, generator).toString()
> to create a proper json string representation. This is not possible with
> JsonOutput though because there is a final constructor and uses a default
> generator. However disableUnicodeEscaping is true by default but it is not
> handled properly by the JsonOutput class. 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 but the toJson() and prettyPrint methods do not handle the
> escaping properly.

> {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 and toJson function
> shall not add escaped strings.* *The Bug is in JsonOutput in the CharBuf
> call.*
> This has to be fixed for toPretty method:
> {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.
