Hello world,
The current rendering for verbatim environments, when line numbers are
enabled, has a significant deficiency: you can't cut-and-paste the
listing without also getting the line numbers and separators.
Looking around at other sites with numbered program listings, the
solution seems to be to use tables. Put the line numbers in the first
column and the listing in the second.
That works, mostly, but if anything in the listing causes a variation in
line height (such as a larger callout), the numbers and the lines get
out of sync.
Using one-line-per-row fixes this, but then cut-and-paste doesn't work
again; the selection crosses over all the columns in each row.
An alternative solution uses nested divs and some slightly fancy CSS.
Naturally, it doesn't work in IE.
I've put an example online: http://nwalsh.com/scratch/out.html
The callout graphics in the listing are intentionally broken because
that was the easiest way to introduce variation. At this font-size,
the callouts are actually ok.
So:
1. Stick with what we have now.
2. Use the table solution and accept the limitation that all lines
must always be the same height.
Why is this an issue Norm? How often in a fixed width font do
users want exponents/Drop caps etc?
3. Find a way to tweak the CSS solution so that IE doesn't fall over
(or chase pixie dust?)
I'm open to suggestions on 3, but I'm not likely to figure it out myself.
Thoughts? Other suggestions?
You've obviated the line numbers by putting content in col 2...
why not finish the job and put co in col 3?
Then I could cut/paste?
HTH
