[ jEdit-users ] JSON Indent macro

[Patrick <am...@gm...>]

Hello,

AFAIK there is no way to format JSON in JEdit. Please correct me if I am
wrong.

So I would like to contribute the following macro to format JSON:



~/jEdit/5.2.0/macros/Text/JSON_indent.bsh :

-------------------------------------------------------------



import java.lang.StringBuffer;

JEditTextArea jeTextArea = (JEditTextArea)textArea;
String originalText = jeTextArea.getText();
char[] chars = originalText.toCharArray();
jeTextArea.setText("");
StringBuffer ret = new StringBuffer();
int indent_width = 1;
int indent = 1;
boolean begin_quotes = false;
String newline = "\n";

for (int i = 0, indent = 0; i < chars.length; i++) {
    char c = chars[i];

    if (c == '\"') {
        ret.append(c);
        begin_quotes = !begin_quotes;
        continue;
    }

    if (!begin_quotes) {
        switch (c) {
        case '{':
        case '[':
            indent += indent_width;
            ret.append(c + newline);
            for (int j=0; j<indent; j++) {
                ret.append(" ");
            }
            continue;
        case '}':
        case ']':
            ret.append(newline);
            if ((indent -= indent_width) > 0) {
                for (int j=0; j<indent; j++) {
                    ret.append(" ");
                }
            }
            ret.append(c);
            continue;
        case ':':
            ret.append(c + " ");
            continue;
        case ',':
            ret.append(c + newline);
            if (indent > 0) {
                for (int j=0; j<indent; j++) {
                    ret.append(" ");
                }
            }
            continue;
        default:
            if (Character.isWhitespace(c)) {
                continue;
            } else {
                ret.append(c);
            }
        }
    } else {
        ret.append(c + (c == '\\' ? "" + chars[++i] : ""));
    }
}
jeTextArea.setText(ret.toString());
