Hi all,
In writing class notes, I frequently make one-letter macros for formatted
symbols, such \v and \w for vectors. Generally speaking, one-letter names for
function/macros/variables is frowned upon in programming, but I find this
localized use very convenient.
In cont-new.mkiv, one finds definitions of \t and \w (via \let) appended to
\everymathematics, which overwrites my definition of \w every time TeX enters
math mode. I can fix this by appending my definition to \everymathematics. The
inefficiency seems minor, and I can live with it. I have a question and a
couple of points:
1. Is there a better way than adding the definition to \everymathematics?
2. I don’t think these definitions should be in ConTeXt. Let users add them if
they wish. Or add a ‘useshortcuts’ option to \setupmathematics.
3. \t and \w are undocumented, \mathword is undocumented, and it took me a
while to track down the bug it created for me. In particular, they overwrote my
definition only in math mode, and “\show\w” did not work in math mode.
Frustrating. I could add a wikipage, I suppose, but I’m not proud of the
extent of my knowledge: “\mathword{word} typesets “word” in math mode in a
normal text font, somewhat like \text{word}, and \w is an abbreviation of it
that is added to \everymathematics on startup.”
adding to \everymathematics can work fine as long as you're the last one
adding
when you overload built in commands,
\enabledirectives[overloadmode=error] % or warning
can give you some protection
