# This code with $LAST_PRESAVED_COMMAND and $LAST_SAVED_COMMAND is necessary to work around a quirk of
|
|
# bash. With bash, if you run the command `foo` and then press `Control+R`, it will trigger the DEBUG
|
|
# signal. And `history 1` will still return `foo` so this will lead to duplicate pre-saves causing entries
|
|
# to show up twice. This works around this issue by skipping presaving if the last commadn we presaved
|
|
# was identical.
|
|
#
|
|
# This does lead to a potential correctness bug since it means if someone runs the same non-terminating
|
|
# command twice in a row, we won't pre-save the second entry. But this seems reasonably unlikely
|
|
# such that it is worth accepting this issue to mitigate the duplicate entries observed in
|
|
# https://github.com/ddworken/hishtory/issues/215.
