I'm writing a package in which I need to save the results of various
long calculations.
I wrote two simple functions;
ToStringHeld[expr_]:=StringTake[ToString[Hold[expr],InputForm],{6,-2}]
SetAttributes[{DefinitionString},{HoldAll}]
DefinitionString[expr_]:=ToStringHeld[expr] <> " = " <>
ToString[expr,InputForm] <> ";\n"
Now, for example, with
b=6;
DefinitionString[b] produces the string "b = 6;\n". Great. I then
write it to a file with, for example
stream=OpenWrite["tmp"];
WriteString[stream, DefinitionString[b]];
Close["tmp"];
I run into problems if in the example above I replace b everywhere
with beta (entered as <esc>b<esc> in the front-end). In this case the
file "tmp" contains an unprintable character (pair of characters, in
fact), whereas I'd like it to contain \[Beta] = 6;.
If I use instead DefinitionString[\[Beta]]>>"tmp", it correctly prints
the string, but with quotation marks, making it useless for input...
Any suggestions?
