A program to convert Mathematica source text to LaTeX
perl mathe2tex.pl <filename>
where <filename> is the .txt file of Mathematica to translate
When considering on how to move forward, there is still the issue of translating top level fractions. This issue is made particularly difficult due to the fact that the FullForm of Mathematica is not available unless it is retrieved by a user-instiantiated REPL of Mathematica. If this issue were to be overcome, or the input be changed from a raw text file to the FullForm of the desired source text, then it would open the opportunity to solve the top-level fraction issue. In addition, if the top-level expression is available, refactoring or adding additional functionality could possibly circumvent the need for Wolframscript. For example, if a functional programming were used (such as OCaml or Racket), we could construct types that match the different expressions available in Mathematica and using the FullForm as input. The key is to use FullForm of the desired expression so that way the program would have access to the expression try and be able to process. For example if it encountered a fraction it could do the following
match e Divide e e -> \frac{process(e)}{process(e)}; Multiply e e -> (process(e))*(process(e)); W n1 n2 e -> \Whyp{process(e_0) process(e_1) ... process(e_n1)}{process(e_0) process(e_1) ... process(e_n2)} etc...
