hello,I've recently worked on adding latex equations syntax and format to
troff. By typing tex equations inside .BL/.EL blocks, the equations will be
transformed to troff equations with .EQ/.EN blocks. it also supports inline
equations by defining the start and end tags like below:
.BL\
groff ships with Eric Raymon's extended manual for pic, but nothing similar
for eqn.
If the AT&T release would permit it, and Gnu would honor AT&T's terms, a
Kernighan/Cherry
document could be distributed with groff.
K&C documents are widely available online. Source text is at

Hi Filip,
the man pages are your friend. While eqn(1) is admittedly not especially
talkative to this effect, your answers can be found in groff_char(7).
There is a whole section entitled "Arrows". Since I am not a
mathematician I cannot answer whether implication arrows are included or
not, but i
Hi,
where can I find all commands that can be run? How do I make implication
arrows and such?
Best regards
Filip

It's because of the "extra line space" function \x.

I didn't notice anything from a quick look. I think I'd need a small
of these when
you create exercises spanning multiple lines.) Now the word
is finished, and groff can start linebreaking if necessary.

Sorry that this was a bit confusing... I have a habit of using
the old-style roff syntax with one- or two-character names.
Here's a slightly revised version using groff's extended syntax

How about this, just to throw some ideas into the pool:

For example, I left out the extra line in the "easy" case

am skilled enough to figure out
how to do it without the fraction, since the lengths of words are different.
The lines for each letter are of a fixed length -- giving different lengths
for each letter would be a
bit too easy.
Thanks.

For the particular effect which you describe, it is not necessary
to use fractions and eqn. You can do it perfectly well u
equations or fractions?

Actually
ery. I guess it would be preferable to make
eqn color-aware (like it is already font- and size-aware),
but that appears harder than it sounds, because for inlining

I'd like to have all eqn terms appear in a single colour.

Any suggestions?
