[sage-devel] Re: fricas pkg in Sage
The installation instructions say that ecl is roughly 3 times slower. Once upon a time, when I was a fricas contributor, it made quite a difference. But back than, sbcl was a no-go for sage (I forgot why). I still love fricas' language. I never underrstood why Python succeeded and Aldor didn't, once it became free. But that's live.

Maybe one reason to prefer ecl is that it is embeddable, which could allow us to have a much faster interface than pexpect? -- You received this message because you are subscribed to the Google Groups sage-devel group.

[sage-devel] Re: fricas pkg in Sage
I'm not sure that fricas *has* to be a package : the current versins (6.4, 6.5beta) already have the fricas interface compiled in : /usr/local/sage-6.5/src/build/lib.linux-x86_64-2.7/sage/interfaces/fricas.py /usr/local/sage-6.5/src/sage/interfaces/fricas.py /usr/local/sage-6.5/local/lib/python2.7/site-packages/sage/interfaces/fricas.py /usr/local/sage-6.5/local/lib/python2.7/site-packages/sage/interfaces/fricas.pyc and fricas() calls a possible systemwide fricas. Successfully. Therefore fricas has the same Sage status as Mathematica, Magma or Matlab. However, the fricas interface lacks a .fricas() method for getting the (a) fricas-palatable representation of some objects. It also lacks somethong to avid the ascii_art default output of fricas, which is quite unparsable by the sage() method (which exists). I also saw somewhere on the list the suggestion of a algorithm=fricas option to integrate(), which seems a very good idea. Nevertheless, having a fricas package which might replace a systemwide fricas installation might help its disemination.

No, your original statement was correct, since we have algorithm='magma' for some functions.

For instance NumberField(x^5+4).galois_group has an option algorithm=magma. Magma can compute galois groups of a much larger class of number fields than the other options can, and magma is (naturally) not a standard package. -- You received this message because you are subscribed to the Google Groups sage-devel group.

I think it was because to build sbcl from source, you needed (and still need) an ANSI-compliant Common Lisp already on your machine.
