I'm struggling to figure this one out and I'm sure it's not this complicated. For some reasonI get the error below from this code:
/*
* GET home page.
*/
exports.index = function(req, res){
exec('ls -l ~/Sites/branches | grep "^d"', function (error, stdout, stderr) {
// var lines = stdout.split("\n");
// var folder;
// lines.forEach(function(line){
// folder = line.match(/([^\s]+)$/igm);
// if (folder!='null') {
// sys.puts(folder);
// }
// });
res.render('index', {
title: 'Express',
lines: 'hi'
});
});
};
I've commented out the lines where I intend to get the data for lines from and simply set lines to a string. It gives me the error below regardless.
Express

I'm using simple HTML for the views and the latest version of express. The view renders fine if I remove the 'lines variable from the render call.
Any ideas?
Thank you,
Luis
If you comment out lines, then lines will not be defined so length cannot be evaluated:
Lines: <%= lines.length %>
If you uncomment that code but for some reason stdout is empty (is stderr populated?) then lines could not be defined as well.
Have you tried checking whether error or stderr !== null and logging it out?
Something like:
function (error, stdout, stderr) {
console.log('stdout: ' + stdout);
console.log('stderr: ' + stderr);
if (error !== null) {
console.log('exec error: ' + error);
}
}
