Error printing as mma format

Question

When I print the following expression as mma format $$ v {\left(\sqrt{f \left(f \alpha \gamma_{x x} \gamma_{y y}-f \alpha {\gamma_{x y}}^{2}+f \gamma_{x x} {w_{y}}^{2}-2f \gamma_{x y} w_{x} w_{y}+f \gamma_{y y} {w_{x}}^{2}-2\gamma\right) {\gamma}^{-1}}\right)}^{-1} $$ using code:

print(_.mma_form())

I got the following error message:

LaTeX error, probably a missing style file. See the output below.

How can I solve this problem?

Comments

It should also have given you the path to the LaTeX log file. Can you send that file please (email to info@cadabra.science), as the above output is truncated.

Microtex branch can give the right result, but I cannot copy it, I don't know where went wrong.

Answer 1

As I said, the MicroTeX branch is work in progress.

You can always copy an expression to the clipboard by using the pyperclip package. For instance,

import pyperclip
ex:=A_{m n};
pyperclip.copy( ex.mma_form() )

Comments

Thanks. But how to copy code? I also cannot copy it.

---

To be precise, it seems that the clipboard is broken and I also can't paste code into Cadabra from anywhere else.

---

Works fine for me both ways if I use the right-mouse-button menu in an input box (the keyboard shortcuts don't work yet).

---

Ok, look forward to your progress for branch microtex.
