I really hope you like this as a solution. Be vary careful that you verify with jshint again after you've fixed the issues. And out of curiosity, how did you manage to get so many broken javascript files?

#!/bin/sh

function fixFile {

  for i in `jshint $1 | grep -i Missing semicolon 

                      | sed -e 's/([^0-9]*)([0-9]*)(.*$)/2/'`;

  do

    sed -i $1 -e $i's/(s*)$/;/'

  done

}



fixFile $1

The above uses jshint to produce some error lines, greps them for the missing semicolon errors only, extracts the line number of each error, then seds the file in place on that line to remove any trailing whitespace and replace it with a semicolon.

The file...

var a = 5, c = 4



function helloWorld() {

  if (this == doesntmakesense)

    console.log('hello' + 'world');

}



console.log(a+c);

console.log('finished')   

...becomes...

var a = 5, c = 4;



function helloWorld() {

  if (this == doesntmakesense)

    console.log('hello' + 'world');

}



console.log(a+c);

console.log('finished');

Where petty semantic errors are ignored, and only semicolons treated.

I'd save the bash script as something like fixFile.sh and then run find . -name *.js -exec ./fixFile.sh {} ;

But please commit beforehand. All commands are run at your own risk ;)
