Why not node-jslint? https://github.com/reid/node-jslint
Could you invoke it via M-x compile instead? I designed the output to be roughly compiler like so you could jump to the errors easily.
Hey, happygiraffe.
I can't quit understand you. What's your requirement?
Sorry, I was wondering if, instead of invoking this function into a separate buffer, you could use the standard M-x compile functionality. Then you automatically get output in a
*compilation*buffer as well as navigation viaC-x backquoteYou have to set the compile-command variable, something like this.(the above also needs:)
Thanks happygiraffe. I rewrote it based on your comment, :)
Also check out https://github.com/purcell/flymake-jslint, which uses flymake to show jslint hints directly in the javascript buffer.
