Sorry, code to produce the sobj is already included in the package. From
jones.py:
def _init(self, path):
"""
Create the database from scratch from the PARI files on John Jones's
web page, downloaded (e.g., via wget) to a local directory, which
is specified as path above.
INPUT:
- ``path`` - (default works on William Stein install.)
path must be the path to Jones's Number_Fields directory
http://hobbes.la.asu.edu/Number_Fields These files should have
been downloaded using wget.
EXAMPLES: This is how to create the database from scratch, assuming
that the number fields are in the default directory above: From a
cold start of Sage::
sage: J = JonesDatabase()
sage: J._init() # not tested
...
This takes about 5 seconds.
"""
from sage.misc.misc import sage_makedirs
x = PolynomialRing(RationalField(), 'x').gen()
self.root = {}
self.root[tuple([])] = [x - 1]
if not os.path.exists(path):
raise IOError("Path %s does not exist." % path)
for X in os.listdir(path):
if X[-4:] == "solo":
Z = path + "/" + X
print(X)
for Y in os.listdir(Z):
if Y[-3:] == ".gp":
self._load(Z, Y)
sage_makedirs(JONESDATA)
save(self.root, JONESDATA + "/jones.sobj")
Modulo collecting the text source that aren't included (but readily
available on a web site), the code to compile the database is already
there! You might want to check with the author if he/she is OK with you
downloading and distributing the text files separately, but for robustness
I think you'd be doing the community a favour by wrapping the data in a
"source distribution" too.
