Hi all, I'm attaching some patches that enable the current version of numexpr (r2142) to:
1. Handle int64 integers in addition to int32 (constants, variables and
arrays). Python int objects are considered int32 if they fit in 32
bits. Python long objects and int objects that don't fit in 32 bits
(for 64-bit platforms) are considered int64.
2. Handle string constants, variables and arrays (not Unicode), with
support for comparison operators (==, !=, <, <=, >=, >). (This
brings the old ``memsizes`` variable back.) String temporaries
(necessary for other kinds of operations) are not supported.
The patches also include test cases and some minor corrections (e.g.
removing odd carriage returns in some lines in compile.py). There are
three patches to ease their individual review:
* numexpr-int64.diff only contains the changes for int64 support.
* numexpr-str.diff only contains the changes for string support.
* numexpr-int64str.diff contains all changes.
The task has been somehow difficult, but I think the result fits quite
well in numexpr. So, what's your opinion about the patches? Are they
worth integrating into the main branch? Thanks!
