Trying to get a list of available JavaScript functions/methods

[thegman]

Hi all,
I'm trying to get list of JavaScript methods/functions in a script
file in much the same a good text editor will, the difference being
that I need to output it to a file or stdout, or some other way of
"getting at it" automatically. I'm not fussy about what language I
use, be it JavaScript or something else. Anyone got any ideas? I've
tried Exuberant Ctags, but that does not seem to work on very advanced
scripts like Ext.

I'm guessing the best way would be to have some kind of interrogation
of a HTMLScriptEleme nt or something, but I can't see how to get a
simple list of functions/methods from that.

Alternatively, any C library for parsing JS might be a good idea, even
Python, Perl, PHP, whatever really, anyone got any recommendations ?

Cheers

Garry

You are about the 1337th person to ask that question here. Care to do
a *little* research before you bother other people with your problems?

I've looked around quite a lot, maybe I'm the worst Googler in the
world or something, but I can't find what I'm looking for, if
someone's got some links, I'd appreciate it.

Thanks

1) Top level functions only or all functions together, including
anonymous and nested ones? The latter one is pretty much impossible w/
o operating on a lower level via XPCOM/C (Gecko) or C++ (IE) - just to
let you know in advance.

2) Custom functions only or everything? Say setTimeout should be in
your list or now?

3) For the running script or for the script source treated as plain
text?

With these questions answered the rest should be rather easy.

All functions, but particularly functions/methods defined in third-
party scripts such as Ext.

Would be good to have setTimeout and other builtins, but not
essential.

Not fussy, I don't mind doing this with JavaScript, or pretty much any
other language.

Thanks for the reply, I've been looking at this most of the day, and
not come up with any bulletproof solutions yet.

Cheers!

What is your level of programming experience? In the particular how
would you define "all anonymous functions"? All named references to a
function or the initial reference only? If you don't understand the
question I can try to rephrase it with a sample.

You didn't understand me. My question was: do you want to study a
running code for method references - or you want to parse some text
say library.js to find all occurrences of "function" string in it and
regexp with it?

My programming experience is longer than I care to remember, but not
JS, not even slightly, which is probably not helping my cause much. I
guess any function/method which is usable, I'd like to list that.

I understand your question, it's just that I'm not bothered which way
I end up doing this, I can use JavaScript in a running browser, and
capture the output, or indeed run some kind of regex thing and get the
results that way, I'm relatively indifferent about how I get this
done, just so long as it works. My first thought was to use something
like ctags, or maybe a Python parser, but I could not find anything
which was much good. My thoughts then turned to using the DOM tree or
something like that, which I'd expect to be a bit more robust, after
all, what understand JS better than a browser?
