This error seems to be happening because we are evaling /usr/local/lib/nodelint/jslint/jslint.js... s.string = s is on line 2557. ... Why are not requiring jslint as a normal dependency instead of evaling it?

node -v v4.0.0

npm -v 2.14.2

[monsur]

FWIW I think the root issue is somewhere in JSLint (or some interplay with JSLint and Node). The line number 46 in the error is a red herring, since that line just evals JSLint.

Vaporware at the moment.

I think this should be {{x.string = s;}} jslint.js:2557

[neka-io]

I'm having the same problem and have tested with both node v4 & npm v2 and node v5 & npm v3 combinations.

Can you cut a new version of this npm module with this fix?

After about 5 minutes of poking around I just commented out the line producing the error, and everything seems to work just fine now. shrug

    function ultimate(s) {
        var x = symbol(s, 0);
        x.from = 1;
        x.thru = 1;
        x.line = 0;
        x.edge = 'edge';
        // s.string = s;
        return postscript(x);
    }

Hey guys,

Sorry, this project hasn't been maintained in a long time 😞 While nodelint was great in the early days of Node.js, the world has moved on in terms of needing support for ES6+ syntax and we've not kept up.

Personally, I've been using ESLint for the last few years and it does a pretty decent job. There are also alternatives like JSHint if ESLint isn't to your liking for some reason.

Apologies for not making it clear that the project wasn't being maintained. I've now updated the repo info to mark that it's DEPRECATED.

A big thanks to those of you who did use it over the years though. Much appreciated!

— Cheers, tav

Wesome, thanks for fair suggestions.
