Problem with js2 mode in emacs-starter-kit

[szimek]

Hi,

The code in starter-kit-js.el file causes some strange behavior in js
files. Whenever I change anything in the file (insert new character,
undo changes), the cursor is automatically moved right after the last
occurence of "f(" string - where "f" is this strange character that is
introduced instead of "function" string.

Commenting out the code inside starter-kit-js.el file fixes this
issue.

BTW. It may be good idea to provide instructions in the wiki/readme
file how to compile js2-new.el file before js-mode can be used.

thanks for that, I was wondering what's with the weird behavior too.
any idea why that happens ?

And how do you compile js2-new? I've been trying a bunch of things and
still just get "You must byte-compile js2-mode before using it.". And
I don't get any javascript syntax highlighting without calling M-x
javascript-mode manually.

Thanks,
Mat

Hey Mat

You can byte-compile js2 mode with M-x byte-compile-file ENTER <path-
to-js2.el>. Then you can use js2-mode for your javascript files
instead of javascript-mode.

Or you can just install it from ELPA. There's even a built-in function in the starter-kit to dealt with this and other not installed packages [1]

The Elpa version of js2-mode is 20080419, whereas the latest is 20080616a.  I'd love to see elpa gain traction, but I get the impression that maintainers don't diligently update their packages.

Thanks, that seemed to work. I kept trying to byte-compile js2-new.el
per comments here: http://code.google.com/p/js2-mode/wiki/InstallationInstructions

Only now there seems to be a bug in this version where every time I
type something in, it jumps me to the first function() in my file.
Anyone else seeing this problem? I'm running a fork of master fe721654.

Thanks,
Mat

Hey Mat,

I've encountered the same problem with *.js files. I think it is a bug
in the starterkit. As far as I van rememember i fixed it in my
configurations. You can get a look at them here:
http://github.com/senny/emacs-configs/tree/master.

Thanks, Senny. I didn't get javascript highlighting out of the box
with this one and you also rebound M-x. How can I compile the js2-mode
stuff now?

[Mat Schaffer]

I found your bindings.el. And tried M-a to byte-compile-file elpa-to-
submit/nxhtml/related/js2.el but now I don't seem to have a js2-mode
command.

Hey Mat,

At the moment i dont have nxhtml mode autoloaded because I dont have
the time to configure it the way i want. You can install js2-mode with
the command: M-a starter-kit-elpa-install ENTER
This should then install all the dependencies from elpa. If you only
want to fix the curser-jump-error for js2-mode in the normal starter-
kit, you cold diff my configurations against the ones from the starter-
kit. I think i've made these changes in a file that already existed.

[Mat Schaffer]

Fair enough. Guess I'll start working on my own fork of starter kit.
Thanks,
Mat

Has anyone managed to fix js mode problem with cursor jumping to the
"function()"?
I checked senny's fork and applied his change to starter-kit-js.el
file (http://github.com/senny/emacs-configs/commit/
51cf3cdce1838cc6e91d73c647cd25a6444d6d59#diff-7), but it still doesn't
work for me.

I've tried it with emacs 22 and emacs 23 on Ubuntu.

Hey szimek

Ive gone trough my changes to the starter-kit and I think the fix was
to comment out the (pretty-lambda) call in the coding-hook function
(starter-kit-defuns.el)

You probably applied the wrong patch from my frok. I think this one
should do the trick (http://github.com/senny/emacs-configs/commit/
421710000c10b1a6eb513835fcdacb15a5f91016)
