Problems:
1- numbers are not on the same horizon

2- superscript is not exactly over the "1st" item

3- i dont know how to add "[]" to the 1st input

can someone kindly modify the code for me please?

Thanks in advance!

At least the last two problems I know how to deal with, if perhaps not cleanly.
I'm no TeX expert, so there might have been a better way--it necessitates making
the superscript into another argument, although this can be empty.

\usepackage{ifthen}

\newcommand\annu[3][]{% HAX
\newdimen\annutempA\setbox0=\hbox{\ensuremath{\scriptstyle{\left[#1\right]}}}\annutempA=\wd0
\newdimen\annutempB\setbox0=\hbox{\ensuremath{^{#3}}}\annutempB=\wd0
\addtolength{\annutempA}{-\annutempB}\ensuremath{_{%
\def\arraystretch{0}%
\setlength\arraycolsep{1pt}% I don't feel like adjusting these
\setlength\arrayrulewidth{.2pt}% two settings
\ifthenelse{\equal{#1}{}}{}{\scriptstyle{\left[#1\right]:}}
\begin{array}{@{}c|}\hline

\end{array}}}^{\ifthenelse{\lengthtest{\annutempA > 0.0pt}}{\hspace{0.5\annutempA}}{}#3}}

First of all, I have to confess that I am so forgetfull that I got the lifecon.sty last year when I was trying yo type something not so complicated. Then I just ignored that and didnt read the manual at all unitl this minute that you brought it up again.

Yes, indeed that the lifecon.sty from durham university is very helpful and contains FULL symbols that I will need.

Thanks!

though it didnt work perfectly
and it still helps

Thank you as well!

Hi there,

However,I do have a problem now.

\lcroof{#2}

I just wonder how I can change the width of the horizontal line in the "angle" symbol?

it's a bit thicker than the vertical line

%\DeclareRobustCommand{\lcroof}[1]{%
%\def\arraystretch{0}%
%\setlength\arraycolsep{1pt}% adjust these
%\setlength\arrayrulewidth{.3pt}% two settings
%\begin{array}{@{}c|}\hline
%\\[\arraycolsep]%
%\scriptstyle #1%
%\end{array}%
%}

i tried to adjust this in the lifecon.sty
but i dont know how wide is that hline

I am working on a LaTeX project in which I need a weird new symbol called a 'mark'
or 'cross'. I'm using a modified version of the \annu symbol. Here is an example

Example from http://en.wikipedia.org/wiki/Laws_of_Form to see how the Cross symbol looks and
how it is used (hit the link for section 5.5.2 Sentential logic).

This is what I came up with by modifying the \annu code:

%G. Spencer-Brown's 'Mark' or 'Cross' symbol
%Modified from \annu, p95, http://www.ctan.org/tex-archive/info/sy ... ols-a4.pdf
%with Array environment

\DeclareRobustCommand{\cross}[1]{%
\def\arraystretch{0}%
\setlength\arraycolsep{3pt}%
\setlength\arrayrulewidth{.4pt}
\begin{array}{@{}c|}\hline\\
[\arraycolsep]%
#1
\end{array}
}

with the following results:

Problems:
1) The symbol needs to maintain its size when empty
2) Should be able to space it properly from definition (I added \, in the example)
3) Should maintain a constant height with lowercase content
