Bug ID: 23080
Summary: add API to define convenience variables
Product: gdb
Version: HEAD
Status: NEW
Severity: normal
Priority: P2
Component: python
Assignee: unassigned at sourceware dot org
Reporter: tromey at sourceware dot org
Target Milestone: ---

It should be possible to define or set a convenience variable from Python.
It would also be good to be able to get the value of a convenience
variable without resorting to gdb.parse_and_eval.

Add basic Python API for convenience variables

This adds a basic Python API for accessing convenience variables.
With this, convenience variables can be read and set from Python.
Although gdb supports convenience variables whose value changes at
each call, this is not exposed to Python; it could be, but I think
it's just as good to write a convenience function in this situation.

This is PR python/23080.

Tested on x86-64 Fedora 26.
