Hi,

In[]:=MakeBoxes[par[a_], fmt_:StandardForm] :=
RowBox[{"(", MakeBoxes[a,fmt], ")"}]

In[]:=par[a^2]*(b + c) // TeXForm

Out[]=(b+c) \left(a^2\right)

Regards

Jens

|
| I have two questions which are related.
|
|
*********************************************************************
| First Question
|
*********************************************************************
|
| In Mathematica versions 3 to 4 (and I believe 5)
|
| I get the following:
|
|
|
| In[1]:= Format[par[a_], TeXForm] :=
|
StringJoin["\\left(",ToString[TeXForm[HoldForm[a]]],
"\\right)"];
|
|
| In[2]:=TeXForm[a*par[b + c]]
| Out[2]//TeXForm= a\,\left(b + c\right)
|
|
| Which is exactly what I would expect to happen.
|
|
|
| However in Mathematica 5.2 I get the following:
|
|
|
| In[3]:= Format[par[a_], TeXForm] :=
|    StringJoin["\\left(",
ToString[TeXForm[HoldForm[a]]], "\\right)"];
|
|
| In[4]:=TeXForm[a*par[b + c]]
| Out[4]//TeXForm= a \text{par}(b+c)
|
|
| How do I get the TeXForm output of my function
par
| to work as it did in Mathematica 4.
|
|
|
|
**********************************************************************
| Second Question
|
**********************************************************************
|
| My second question is related to the first.
Namely how is
| Mathematica 5.2 now handing the Format command
for TeXForm verses
| how it used to in version 4.
|
|
|
| In the Mathematica 4 and 5 book the following
example is given
| as an illustration of the Format statement.
|
|
| In[5]:=  Format[x, TeXForm] := "{\\bf x}";
| In[6]:=   TeXForm[1 + x^2]
| Out[6]//TeXForm= 1 + {{\bf x}}^2
|
| This is what one would expect.
|
|
|
|
| However in the online documentation for
Mathematica, the above
| example is given as
|
|
|
| In[7]:=  Format[x, TeXForm] := "{\\bf x}";
| In[8]:=   TeXForm[1 + x^2]
| Out[8]//TeXForm= x^2+1
|
|
|
| So the example in the documentation makes it
appear that nothing
| has happened.
|
|
| When I execute these same commands in
Mathematica 5.2 this is,
| in fact, what happens.
|
|
|
|
| In Mathematica 5.2 I get the following:
|
| In[8]:= Format[x, TeXForm] := "{\\bf x}";
| In[9]:=TeXForm[x]
| Out[9]//TeXForm=\text{$\{\backslash \backslash$bf x$\}$}
|
|
|
|
|
|
|
| In Mathematica 5.2 I also get the following
|
|
| In[10]:=TeXForm["{\\bf x}"]
| Out[10]//TeXForm=\text{$\{\backslash \backslash$bf x$\}$}
|
|
|
| So it appears that when the commands
|
| In[11]:= Format[x, TeXForm] := "{\\bf x}";
| In[12]:=TeXForm[x]
|
| are executed
|
| Mathematica 5.2 is converting x to "{\\bf x}"
and
| then is again converting "{\\bf x}" to
| \text{$\{\backslash \backslash$bf x$\}$}.
|
| Can someone explain what is happening here?
| I have contacted Wolfram's technical support
several times, with
| no success whatsoever. I have dozens of special
TeXForm changes that
| I need to implement all of which worked as
expected in Mathematica 3 and
| 4.
