Magma on a mac
VictorMiller
sure that the magma command is on my PATH. Yet when I run sage, and I
try and call to magma.eval, it says that it can't find magma. This
has worked without problem on my linux workstation at work. So what
needs to be done to have sage find my installation of magma? The page
http://www.sagemath.org/doc/reference/sage/interfaces/magma.html
doesn't say anything about this.

Start sage and type
sage: !magma
What happens?

!magma
it starts up Magma. I then exit from it (by typing "exit;") and start
the notebook.
However, if I try to run magma from the notebook, I get the message
"Type Error: unable to start magma"
What's going on?

What happens if you do this on the command line:
sage: magma.eval('2+2')
What happens if you type this in a notebook cell:
sage: os.system('magma')

os.system('magma')
It's now over 5 minutes, and it still hasn't come back! While I was
waiting I went a terminal and typed magma and it started within less
than a second.
Something weird.

Does it say anything in the notebook log (i.e., the screen you
originally launched the notebook from)?

What about
os.system('magma < /dev/null')

notebook, quite sage, and then restart sage. Now when I try
os.system('mamga') it comes back right away with
Can't open Magma password file
.magmapass
256
However, I have no trouble starting magma from a terminal or from sage
in command line mode.

OK, then I'm stumped. I don't understand the mysteries of Magma's
proprietary copy protection.

I wonder if it just can't find the magma password file. After skimming
http://magma.maths.usyd.edu.au/magma/prot/prot.html
it looks like you can (must?) set the MAGMAPASSFILE environment
variable. Can you try:
os.system('export MAGMAPASSFILE=<wherever this is> && magma')
or
import os
os.environ['MAGMAPASSFILE']

No, do
os.system('export MAGMAPASSFILE=<wherever this is> && magma < /dev/null')
so you don't just hang things.

but never set up MAGMAPASSFILE as an environment variable. For some
reason when I started magma from the command line, or with !magma this
didn't bother it, but from the notebook it did. I added something to
set MAGMAPASSFILE in the magma script and now everything works ok.

following line in my ~/.bash_profile file
MAGMAPASSFILE=.magmapass
However, it should have been
MAGMAPASSFILE=~/.magmapass
so that's why it couldn't find it because it was running in a
directory not my home directory.
