Is there a reverse operator to "stringify[]" or "jsonstringify[]"?

[pimgeek]

I want to stringify an ASCII & Unicode mixed string, do some operations and then Un-stringify it, here is the filter I used:

\define ascii-regex() ([\u0000-\u007f])
{{{ 'abc一二三' +[search-replace:g:regexp<ascii-regex>,[$1..]jsonstringify[]split[]first[15]join[]search-replace:g:regexp[\.\.],[]] }}}

I expact an output like abc一

Now I'm wondering how to turn \u4E00 back to normal. 😓

I solved it by creating 2 customized String Filter operators. Is there any non-intrusive way to achieve this?

exports['js-escape'] = function(source,operator,options) {
    var results = [];
    source(function(tiddler,title) {
        results.push(escape(title));
    });
    return results;
};

exports['js-unescape'] = function(source,operator,options) {
    var results = [];
    source(function(tiddler,title) {
        results.push(unescape(title));
    });
    return results;
};

Then I use them to escape and unescape:

\define ascii-regex() ([\u0000-\u007f])
{{{ 'abc一二三' +[search-replace:g:regexp<ascii-regex>,[$1..]js-escape[]split[]first[15]join[]search-replace:g:regexp[\.\.],[]js-unescape[]] }}}

Hi @pimgeek TW currently doesn't have the reverse operators to stringify or jsonstringify, and I think it would be reasonable to add them. I'll convert this to an issue, might you like to create a PR for the change?

I'd like to, is there a guideline page for submitting PR? ☺
