A stationary header and footer with scrollable area in the middle creates
a much improved user experience compared to the old “dumb terminal” interface,
especially for large tracking wallets.
Scroll with either the Vi keys or up/down/arrow keys.
All tracking wallet views supported: unspent outputs, address list, tx history.
Activate with --scroll on the command line, or by setting the `scroll` option
in the config file.
This feature is entirely opt-in. The old behavior continues to be supported
without alteration.
Sample invocation:
$ mmgen-txcreate -qi --scroll
Interactive testing:
# run the required regtest test dependencies:
$ test/test.py -d regtest.view
# test the scrolling UI interface interactively:
$ PYTHONPATH=. MMGEN_TEST_SUITE=1 cmds/mmgen-tool --bob --scroll listaddresses interactive=1
# when finished, stop the regtest daemon:
$ test/stop-coin-daemons.py btc_rt
Bitcoin Core and code forks thereof provide no mechanism for deleting addresses
from a tracking wallet. Enter tracking wallet exporting with address pruning:
calling ‘mmgen-tool twexport’ with the ‘prune=1’ option launches an interactive
prune menu, allowing the user to delete unwanted addresses from the JSON wallet
dump. A new tracking wallet can then be easily created from the pruned dump
using ‘mmgen-tool twimport’.
Testing/demo:
# run the dependencies for the regtest ‘twprune’ test:
$ test/test.py -d regtest.twprune
# run the test, displaying output:
$ test/test.py -SA --demo regtest.twprune
This patch introduces an improvement to commit cbe749813 (automatic change
address selection)
Instead of supplying a Seed ID + address type, users may now specify the
address type alone. If the tracking wallet contains more than one unused
address matching the user’s criteria, the user is prompted to choose a specific
change address.
As with plain auto change address selection, this feature is entirely opt-in.
Sample invocations:
# old invocation:
$ mmgen-txcreate -q 35N9FntsNwy98TmjFHyCpsBVDVUs5wDPfB,0.123 01ABCDEF:B
# new invocation:
$ mmgen-txcreate -q 35N9FntsNwy98TmjFHyCpsBVDVUs5wDPfB,0.123 B
# or, alternatively:
$ mmgen-txcreate -q 35N9FntsNwy98TmjFHyCpsBVDVUs5wDPfB,0.123 bech32
Testing/demo:
# run the regtest test partially, leaving the coin daemon running:
$ test/test.py -D regtest.auto_chg
# run the auto chg addrtype test, displaying script output:
$ test/test.py -SAe regtest:bob_auto_chg_addrtype1
# view the addresses in Bob’s tracking wallet, verifying that the first
# unused ones in each grouping were chosen as change outputs:
$ PYTHONPATH=. MMGEN_TEST_SUITE=1 cmds/mmgen-tool --bob listaddresses interactive=1
# When finished, gracefully shut down the daemon:
$ test/stop-coin-daemons.py btc_rt
Instead of selecting a specific change address, i.e. '01ABCDEF:B:7', users can
now omit the address index, specifying '01ABCDEF:B' instead, and the script
will automatically choose the first unused address in the tracking wallet
matching the requested seed ID and address type.
This feature is entirely opt-in. Existing behavior continues to be supported
without alteration.
Sample invocations:
# old invocation:
$ mmgen-txcreate -q 35N9FntsNwy98TmjFHyCpsBVDVUs5wDPfB,0.123 01ABCDEF:S:7
# new invocation:
$ mmgen-txcreate -q 35N9FntsNwy98TmjFHyCpsBVDVUs5wDPfB,0.123 01ABCDEF:S
Testing/demo:
# run the regtest test partially, leaving the coin daemon running:
$ test/test.py -Dn regtest.view
# run the 'auto_chg' test group, displaying script output:
$ test/test.py -DSAe regtest.auto_chg
# view the addresses in Bob’s tracking wallet, verifying that the first
# unused ones in each grouping were chosen as change outputs:
$ PYTHONPATH=. MMGEN_TEST_SUITE=1 cmds/mmgen-tool --bob listaddresses interactive=1
# When finished, gracefully shut down the daemon:
