It would be nice to have a more useful error message if a browser is
not found. I'm

Or
sage: SR(s)
x^3
sage: SR("2a+5x^2-sqrt(pi)")
5*x^2 + 2*a - sqrt(pi)
so y

Hi,
I see some problems with this source browser.
1. there are no line numbers for a source file.
2. it is difficult to navigate through hierarchy as there is no "go up
to the parent directory" link or ".."
3. files are not sorted on the alphabetic order. I don't know in what
order the files a
This is all I need. Thank you!

Hi,
FormalSum arithemtic appears to be broken when the parent is a Galois field:
sage: a = FormalSum([(1,'x')],parent=GF(7))
sage: 1*a
0
sage: a*1

I would prefer 3*(x**2)
{3 {x}^{2} }
is not a valid pstricks's syntax, and I don't see how to manipulate it
in order to get something valid.
Maybe I can make the replacement { -> ( and } ->), but I fear some side

Hello everybody
I wrote the following :
++
#! /usr/bin/sage -python
# -*- coding: utf8 -*-
from sage.all import *
s = "x**2"
var('x')
f = sage_eval(s)
print f(2)
++
I would have expected the result to print 4.
Since I'm using Sage from yes
Hi,
I am wondering how I could start the source browser in the notebook
