Error on Mac OSX El Capitan

[RaviWoods]

Tried to run this on Mac OSX El Capitan (10.11.5), and this error was thrown:

readline.js:73


    terminal = !!output.isTTY;
    
                       ^
                       
TypeError: Cannot read property 'isTTY' of undefined

This used the following JS code:

var parser = require("node-c-parser");

parser.lexer.cppUnit.clearPreprocessors("./return.c", function(err, codeText){
    if(err){
        console.log(err);
    }
    else{
        var tokens = parser.lexer.lexUnit.tokenize(codeText);
        var parse_tree = parser.parse(tokens);
        console.log(parse_tree);
    }
});

And the following C code

int main() {
    return 0;
}

@RaviWoods, Hi. Sorry for this late reply after one and a half years. I don't have any MacOS. So can't try to reproduce the issue in my end. Can you please verify it from your side whether this is a legitimate issue to look at and submit a pull request if any fix is needed?

[lemire]

I cannot reproduce on macOS High Sierra.

[taufique71]

@lemire Do you think the issue should be closed then?

[lemire]

What I get is this...

> var parser = require("node-c-parser");
undefined
>
> parser.lexer.cppUnit.clearPreprocessors("test.c", function(err, codeText){
...     if(err){
.....         console.log(err);
.....     }
...     else{
.....         var tokens = parser.lexer.lexUnit.tokenize(codeText);
.....         var parse_tree = parser.parse(tokens);
.....         console.log(parse_tree);
.....     }
... });

This library uses node-c-lexer as dependency. node-c-lexer has a dependency on cpp command for pre-processor expansion. Can you confirm cpp is available on your machine?

[lemire]

I do:

 $ cpp --version
Apple LLVM version 9.1.0 (clang-902.0.39.2)
Target: x86_64-apple-darwin17.6.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

@lemire , I guess then there is some issue with MacOS. But the issue is with node-c-lexer library which is a dependency of this project. So reporting it there would be more appropriate. I will request you to create an issue there. I could have created an issue there but as I didn't face the issue from my side I thought more appropriate person would be the one who found it. And I am closing this issue for now.
