I don't believe this is formally documented as such. I figured it out slowly but looking at the definition of solve, seeing it called m.solve, somehow figuring out that this called maxima.eval... it would be worth adding, but time is the issues; many of us who have figured it out are trying to figure out how to add Maxima or plotting functionality to use, not to document how we figured it out. That is unfortunate. sage: maxima.eval? and sage: maxima._eval_line?? may help a bit more. > > A google search for "sage log pexpect" yields this as the second hit: > > http://www.mail-archive.com/sage-devel@googlegroups.com/msg19464.html > > which says: > > First > > export SAGE_PEXPECT_LOG=yes > > this environment variable will cause all pexpect traffic to be logged > to files in $DOT_SAGE/pexpect_log, i.e. usually $HOME/.sage/ > pexpect_log. > > That way you can see *exactly* what was passed to maxima and what came back. > > ja...@littleone:~$ export SAGE_PEXPECT_LOG=yes > ja...@littleone:~$ sage > ---------------------------------------------------------------------- > | Sage Version 4.1.2.alpha2, Release Date: 2009-09-21 | > | Type notebook() for the GUI, and license() for information. | > ---------------------------------------------------------------------- > ********************************************************************** > * * > * Warning: this is a prerelease version, and it may be unstable. * > * * > ********************************************************************** > sage: var('x') > x > sage: solve(x^2-1==1,x) > [x == -sqrt(2), x == sqrt(2)] > sage: > Exiting SAGE (CPU time 0m0.14s, Wall time 0m31.32s). > Exiting spawned Maxima process. > ja...@littleone:~$ cat ~/.sage/pexpect_logs/maxima-6160-173321188-2.log > ;;; Loading > #P"/home/jason/scratch/sage-4.1.2.alpha2/local/lib/ecl-9.8.4/defsystem.fas" > ;;; Loading > #P"/home/jason/scratch/sage-4.1.2.alpha2/local/lib/ecl-9.8.4/cmp.fas" > ;;; Loading > #P"/home/jason/scratch/sage-4.1.2.alpha2/local/lib/ecl-9.8.4/sysfun.lsp" > Maxima 5.19.1http://maxima.sourceforge.net > Using Lisp ECL 9.8.4 > Distributed under the GNU Public License.
