The current version of JSlint (at least on Rhino) exits with code 1 if it cannot read the file and 0 otherwise. If it instead would exit with 0 only if the...
The current version of JSlint (at least on Rhino) processes a single file. Since Rhino takes a noticeable time to start up (as much as 10 seconds), it would...

... "var true;" or "var (1==1);" wouldn't be valid, so there's no ambiguity about "var row=rows[i]" - it's obviously an assignment. The problem with for(var i...
... Thanks for the reply. I've never seen an example of where the slash in regex literals could be ambiguous for either humans or the parser. As far as I know,...
... I see... so wrapping the assignment in braces is simply a way to signify that yes, you intended to do an assignment. Slightly more verbose, but in the end...

It turned out *really well* -- it runs literally 100 times faster -- but I don't know how to share it. Should I just put it in a message here or is there an...

Hope this might help someone- I use jslint in my build process from ant as well and it works great (although it's a really old version of jslint...) If you...
