New Features

monocle whois

This pull request adds a new subcommand monocle whois that allows querying AS and organization information with ASN or name text.

This function has the following features:

• one bootstrap and offline use forever
  • 1 minute bootstrap time
• "smart query": search based on input, 400644 -> search by ASN, bgpkit -> search by AS name
  • can always fall back for force searching by ASN or name
• output to table and order entries by organizations' sizes
• SQLite as storage backend, so users can always run queries directly on the database
  • The database is stored at ~/.monocle/monocle-data.sqlite3 by default

Monocle Configration

This pull request also adds the initial support for configuring Monocle's behavior. There are two ways to pass configuration values to the function:

1. by environment variable with prefix MONOCLE_
2. by changing TOML configuration file at ~/.monocle/monocle.toml

Currently, we have one supported variable:

• data_dir: the directory where the Monocle's SQLite datafile will be stored

Users can configure data_dir to ~/DATA in two ways: set environment variable MONOCLE_DATA_DIR=~/DATA or have a data_dir="~/DATA" in the ~/.monocle/monocle.toml file like below

### monocle configuration file

### directory for cached data used by monocle
data_dir="~/.monocle"
