A TUI client for Hyperledger Iroha. Works only with python3.6+.

From the source directory:

$ python3 -m iroha_tui

$ python3 -m iroha_tui --help
usage: __main__.py [-h] [--config CONFIG]
                   [--persistence-file-path PERSISTENCE_FILE_PATH]

optional arguments:
  -h, --help            show this help message and exit
  --config CONFIG, -c CONFIG
                        Config file path
  --persistence-file-path PERSISTENCE_FILE_PATH
                        File path to persist transactions and queries to.
                        Needs to be both readable and writable.

There are several ways to set and option (in order of precedence):

• Command-line argument.
• Environment variable.
• Configuration file.

Parameter names are converted as follows (consider parameter_name):

• Command-line argument: --parameter-name (notice how _ changed to -).
• Environment variable: IROHA_TUI_PARAMETER_NAME.
• Configuration file: {"parameter_name": "value"}.

Configuration file is simple JSON. For example, consider this one:

{
    "persistence_file_path": "/home/user/.config/iroha_tui/config.json"
}

This will set a parameter named persistence_file_path to that path. You can also override any parameter first from environment, e.g.:

$ IROHA_TUI_PERSISTENCE_FILE_PATH=/home/user/.config/iroha_tui.json python3 -m iroha_tui

And also this can finally be overriden from command line arguments:

$ python3 -m iroha_tui --persistence-file-path /home/user/.config/iroha_tui.json

• persistence_file_path - path to a writable file to persist transactions and queries to.

  This file will automatically be created and managed. It is opened only on startup and on exit.

You can specify the config file using an environment variable, and configure persistence for convenient launch using only iroha_tui without any parameters.

To do this, execute the following:

$ cat <<EOF > ~/.bash_profile
alias iroha_tui="iroha_tui -c ~/.config/iroha_tui/config.json"
EOF
$ mkdir -p ~/.config/iroha_tui
$ cat <<EOF > ~/.config/iroha_tui/config.json
{
    "persistence_file_path": "~/.config/iroha_tui/persistence.json"
}
