Description (last modified by embray)

It's about time. The sooner this is done, the fewer code to cross pexpect gap/libgap boundary will have to be written. Some concrete tickets aiming at this:

Use GroupHomset_libgap for permutation groups, as well
use libGAP in MatrixGroup.as_permutation_group()
Implement method `gap` of class `PermutationGroupElement` properly.
conversion of posets to libgap
from gap to libgap in strongly_regular_db
convert guava interface to libgap

Also related:

Remove the "-r" option in calling gap in the pexpect interface
Do not restrict to a predefined list
libgap: do not restrict libgap.<tab> completion to a fixed list

Following completion of this work, we can look into formally deprecating the pexpect interface to GAP: #26963.

I've created a follow up ticket #27234 to #26750, since by the improvements in connection with GAP 4.10 upgrade, the implementation of the gap method of class PermutationGroupElement can be done properly, right now.

  • Milestone changed from sage-8.7 to sage-8.8

Ticket retargeted after milestone closed (if you don't believe this ticket is appropriate for the Sage 8.8 release please retarget manually)

  • Milestone sage-8.8 deleted

As the Sage-8.8 release milestone is pending, we should delete the sage-8.8 milestone for tickets that are not actively being worked on or that still require significant work to move forward. If you feel that this ticket should be included in the next Sage release at the soonest please set its milestone to the next release milestone (sage-8.9).
