since this release
Stable version of the Mac Lane infrastructure for discrete (pseudo-)valuations which should work on an unmodified Sage 7.4 or later.
To use, download the attached archive and
$ tar zxf mac_lane-1.7.1.tgz
$ sage
sage: from mac_lane import *
sage: pAdicValuation(QQ, 2)
2-adic valuation
The code heavily uses assert statements. These checks can be quite expensive. To disable them, start sage as PYTHONOPTIMIZE=yes sage.
Changes in this version
- Performance improvements
- Allow number fields written as quotients of polynomial rings
