# Miscellaneous (La)TeX Macros

### Paul Taylor

### 1986-2006

Since helping other people with their (La)T_{E}X problems has only ever
caused me grief
(and in particular, maintaining a then state-of-the-art T_{E}X system
for the *whole* of Imperial College for fife years
led directly to my losing my job there),
I no longer maintain T_{E}X macro packages or answer questions about T_{E}X.
That is, with the exception of my
categorical diagrams package.
There is also a separate page for
proof trees, proof boxes and QED (the right-justified end-of-proof mark).
In other words, you use the following entirely at your own risk.
However, the usual courtesies apply: **acknowledge**, in particular
when you circulate your own versions of my macros.
One widely circulated thing is my
alphabetical list of mathematical symbols.
People sometimes ask about the 2-cum-omega symbol that I used for the
subobject classifier in a topos in my book.
The answer is that, if you would like to take on the responsibility of
designing an entire new font of mathematical symbols using MetaFont
(including the hassle of responding to checksum errors generated by
dvips) then I am willing to give you my MetaFont source code.

- abbrevs.sty: abbreviations such as
*i.e*. and
*e.g*. in italics.
- barcodep.sty: generates supermarket barcodes.
- daymonthyear.sty: British (not American) style dates.
- dropcap.sty: dropped capitals for the start of a chapter
in a book.
- eqnarray.sty: allow a "reason" as the fourth column
of an
`eqnarray` enivironment in L^{A}T_{E}X.
- letterlist.sty: itemisations with letters, greek letters,
roman numerals, etc., with L
^{A}T_{E}X `label`s that include the
surrounding enumeration (for example of a theorem number) and
the option to continue the previous enumeration.
- logicsym.sty: miscellaneous symbols suitable for logic,
together with alphabets in various fonts.
- ordinals.sty: matchstick pictures of ordinals.
- private.sty: bracketted comments that can be included or
excluded at the flick of a switch.
- pthref.tex: generate hyperlinks with given base url,
and support
for HTML (using TTH)
and PDF (using pdftex).
Use "
`\input pthref`" not `\usepackage{pthref}`
to make TTH read it.
- rotatept.sty: PostScript code for rotating symbols,
basd on Rokicki's.
