# Note 1: use the eev command (defined in eev.el) and the
# ee alias (in my .zshrc) to execute parts of this file.
# Executing this file as a whole makes no sense.
# An introduction to eev can be found here:
#
#   (find-eev-quick-intro)
#   http://angg.twu.net/eev-intros/find-eev-quick-intro.html
#
# Note 2: be VERY careful and make sure you understand what
# you're doing.
#
# Note 3: If you use a shell other than zsh things like |&
# and the for loops may not work.
#
# Note 4: I always run as root.
#
# Note 5: some parts are too old and don't work anymore. Some
# never worked.
#
# Note 6: the definitions for the find-xxxfile commands are on my
# .emacs.
#
# Note 7: if you see a strange command check my .zshrc -- it may
# be defined there as a function or an alias.
#
# Note 8: the sections without dates are always older than the

Note: due to a bad design decision the elements of ds are "in the
wrong order" - to push a new element we move the old elements from the
positions 1..n to 2..n+1, and then we set ds[1] to the new element...
this simplifies accessing the elements at the top of the stack, but
complicates all the rest - especially "@" and operations with the
array "depths".

One possible fix (dirty trick): use a metatable with a "__call" entry
for the table "ds"; make ds(2) return ds[-2] for any value of 2.

subject	categories: ticked arrowheads in xy-pic and diagxy
	
A month or two ago, Micah McCurdy wrote to ask me if it was possible to
make an arrow with a tick in the middle (that is ----+---->) and I said I
didn't know how to do that and suggested he ask Ross Moore.  Ross told him
that xy-pic didn't have that capacity.  Well, Micah discovered that it
did.  Here are some samples, using diagxy, but that is just a front end to
xy-pic.

%*

 $$\bfig
 \node a(0,0)[A]
 \node b(300,400)[B]

 $$\bfig

 \efig$$

 $$\bfig
 \morphism/@{>}|-*@{|}/<700,0>[ABCDE`F;h]
 \efig$$

%*

As far as I can tell, the * between the - and the @ has no effect.  The
one limitation is that what goes inside the -@{ } must be a \dir.  This is
a limitation for me, since I cannot figure out the syntax of \newdir.  For
this to work, it clearly has to be something that tex can rotate.

subject	categories: More arrow decorations
	
By playing with Micah's discovery (which is actually documented on page
39, third line from the bottom of Fig. 13), I have come up with the
following potentially useful decorations:

%*
% (eedn4a-bounded)

 $$\bfig  \morphism/@{>}|-@{|}/<500,500>[A`B;f]  \efig$$

 $$\bfig  \morphism/@{>}|-@{x}/<500,500>[A`B;f]  \efig$$

 $$\bfig  \morphism/@{>}|-@{o}/<500,500>[A`B;f]  \efig$$

 $$\bfig  \morphism/@{>}|-@{*}/<500,500>[A`B;f]  \efig$$

 $$\bfig  \morphism/@{>}|-@{||}/<500,500>[A`B;f]  \efig$$

 $$\bfig  \morphism/@{>}|-@{)}/<500,500>[A`B;f]  \efig$$

 $$\bfig  \morphism/@{>}|-@{(}/<500,500>[A`B;f]  \efig$$

%*

The same ideas also work in native xy-pic and, for all I know, in the
matrix version as well.

This is a set of slides showing how to interpret the three ``Yoneda
Lemmas'' as diagrams with five or six nodes each, in a way in which
each node and arrow can be interpreted precisely as a term in a type
system or in Agda.

These 5- or 6-node diagrams do not have all the details needed for the
translation into terms, but we show how to infer the missing details
using the technique of ``internal diagrams''.

https://tug.org/pipermail/tex-live/2019-July/043931.html

Packages that only have Lua files
Hi List,

Are there any examples on CTAN of packages that are made of Lua files
only, except for documentation? I have this package here, that I would
like to submit to CTAN soon - i.e., in a few months - that is like
that...

  http://angg.twu.net/dednat6.html

In order to use it, in, say, foo.tex, one has to copy to the same
directory of foo.tex the file "dednat6load.lua" and the directory
"dednat6/" - that only contains Lua files.

  Thanks in advance!!!
