[Edbrowse-dev] jdb redirect

[Karl Dahlke]

Anticipating the work that Kevin is doing, it occurs to me that we want a way to dump long output into a file.
This will typically be  document.scripts[7].data
the deminimized version of javascript, which could easily be 100K.
Use tab to dump it into a file.

expression tab file

Then edit the file and go to the offending line number.

tab is truly unused, and it's a single character, but I realized, after I pushed,
that this can be trouble for those of you who use readline.
It might try to do tab completion or some such.
I could perhaps disable readline mode when running in jdb mode,
or maybe there is a better character than tab.
Any thoughts?

It's also not distinct in some speech adapters.  Why not

That would only allow filenames without whitespace; no great loss.
It would be as easy to parse, if a little unintuitive.

reminds me of German where you throw the verb way out at the end of the sentence.
It just doesn't parse well in my brain.
I'd rather use ^ or ^> or some other visible symbol that is almost never used in js.

Thank you for this idea.  I would use this all the time.

There seems to be some kind of regression when I add esprima and escodegen 
to third.js.  My crude test was to add the new libraries and then try 
nasa.gov.  Nasa reverted to no body loaded, like before.  So I am still 
working on this.  I wonder if there's some problem with the order in 
which things are digested.  I may get it this evening.

It works!  The following could be a sample usage of the new libraries and 
the redirect to file, put together:

escodegen.generate(esprima.parse(document.scripts[3].data))     outfile
2097837 bytes

Very cool.  It's saved to the filesystem and it has the linefeeds, in 
very few steps!

In case we wanna switch from tab, no problem as far as I'm concerned.
