# mmgen-wallet-nix: Nix packages directory for mmgen-wallet
#
# Copy the ‘mmgen-wallet-nix’ directory and its files to a location outside the
# mmgen-wallet repo and edit the file ‘packages.nix’, which contains all the
# system and Python packages MMGen Wallet depends on.  By default, altcoin
# packages are commented out.  To enable the coins you need, uncomment the
# relevant lines.  For an XMR-enabled setup, for example, you’ll need the
# system package ‘monero-cli’ and Python packages ‘monero’, ‘pycryptodome’
# and ‘pysocks’.
#
# Individual system packages are built as follows:
#
#    $ nix-build /path/to/mmgen-wallet-nix/packages.nix --attr <package name>
#
# The last line of nix-build’s output is a store path in ‘/nix/store/’, which
# you may optionally install into your default environment as follows:
#
#    $ nix-env --install <store path>
#
# To build all configured packages in one go, run nix-build without ‘--attr’ and
# package name.
#
# The file ‘shell.nix’ contains a shell environment specially created for use
# with MMGen Wallet.  From the mmgen-wallet repo root, execute:
#
#    $ nix-shell /path/to/mmgen-wallet-nix/shell.nix
#
# This will build any unbuilt configured packages and drop you to the custom
# environment.  At this point you may run the test suite:
#
#    [nix-shell:... $] test/test-release -FA
#
# or proceed to use MMGen Wallet as with any conventional installation.
#
# For greater isolation, you can invoke nix-shell with the ‘--pure’ option. This
# will make executables in your native environment inaccessible within the
# shell, so you may need to install some additional tools, such as a text
# editor. See the related comments below.
#
# NixOS:
#
#   To install mmgen-wallet under NixOS, copy the ‘mmgen-wallet-nix’ directory
#   to ‘/etc/nixos’, edit ‘packages.nix’ to suit and add
#   ‘mmgen-wallet-nix/nixos-packages.nix’ to your imports list in
#   ‘configuration.nix’.  From the mmgen-wallet repo root, execute:
#
#       export PYTHONPATH=$(pwd)
#       export PATH=$(pwd)/cmds:$PATH
#
#   You can now use MMGen Wallet in your native shell environment.
