I am trying to produce a patch with a new file (stuffle_algebra.py)
following this tutorial:
http://www.sagemath.org/doc/developer/walk_through.html#section-create-sandbox
When I run the command hg_sage.diff(), I get a blank file; moreover, I can
not save the commit message: when I answer Trac
this is clear..

Thank you for your answer which was very useful. I have now another
problem.
In order to define the product of two primitive elements (P_l for l a
Lyndon word), I think I need the structure equivalent to that of the
CombinatorialFreeModule but in the case of monoids, something that others
I try to implement the Poincaré-Birkhoff-Witt basis of the free algebra.
I defined the elements of this basis and a function which gives the
expansion of an element of the free algebra on this basis; actually, it
returns a dictionary whose keys are monomials and whose values are the
In a recursive function, I use a dictionary (which contains the elements of
the expansion of the argument on another basis). Since each call to the
function needs the dictionary, I don't want the user to be forced to put
the dictionary as an argument (i.e. I want him to call to_pbw(elem)
. See http://effbot.org/zone/default-values.htm . If you
replace it with None do something like
if l is None:
l = {}
at the beginning of the function, then things should be okay.

I found the solution : the problem was that the definition of my function
was in the class free monoid element whereas it has to be written outside
if you want to import it.

I wrote some functions about the free algebra on two
generators(bialgebra structure, some bases, scalar product...). I do
not know how to make the best of it and I think that my skills are not
good enough to add them to Sage myself.
Any feedback and/or collaboration would be welcome.
Here is my
I was told to post here some code that I wrote about the free algebra.
I do not know what is the best way to make it useful and would be
thankful for any advice. If someone is interested in a collaboration
to improve it or publish it, please let me know...

I tried to remove all the french expressions in my code.
## Lyndon words ##
import sage.combinat.lyndon_word as LW
## Shuffle product ##
from sage.combinat.words.shuffle_product import ShuffleProduct_w1w2 as
SP
## Combinatorial
Hello,
I don't know if I write to the right group. Please tell me if I am
wrong.
I try to install sage-combinat but it doesn't work.
I use Sage 4.7. I tried to use the command sage -combinat install in
the sage root directory and got the following error message:
[root@localhost sage]# sage
