I suspect there's a library we can use for this,
but can't think what it's called.

Both would be nice. I have to say, until I loaded my first multi-hundred mb
ascii file into edbrowse I'd never thought 10000000 lines was a problem.

Yeah, in theory, but I've seen errors from substitutions complaining that the
result would be longer than (I think) 40000 bytes.
This (I seem to remember) was caused when trying to debug a js error which
involved trying to read a minified version of some js lib (basically remove
newlines, comments etc). I was trying to run:
s/;/;\n/g
To make the file almost readable. I don't have a test case for this I'm afraid.

I know the line is stored internally in the edbrowse buffer faithfully, but I
guess by line length I should have said editable line length (i.e.
the length of line one can perform editing commands on,
regardless of whether the results are fully displayed).

What distro?

The download url I used for mozjs 24 is (source version):
https://ftp.mozilla.org/pub/mozilla.org/js/mozjs-24.2.0.tar.bz2

I can't remember what it needs in terms of dependancies, but if you uncompress, cd js/src and the ./configure you should see a whole load of stuff including any failures.

For debugging edbrowse I built with:
./configure --prefix <whereever_you_put_custom_stuff> --disable-optimize --enable-debug
make
make install

The --enable-debug meant I didn't need to mess around with manually setting
CFLAGS etc and the --disable-optimize makes things nicer when using gdb.

As you said, compiling from source in this case really does make life easier.
Even with the debian package's debugging symbols I still needed to use my own
compiled version to get any real debugging done due to the fact that most
(hopefully all) distros will package mozjs 24 with optimizations enabled.

Cheers,
Adam.
