Usage

Crypto will eventually have a number of subcommands. Execute: crypto --help in order to check them out.

Flags

A --watch flag is available for a number of commands, including track and graph, this allows you to loop the same command every second.

Track

Track was initially intended for something like Polybar for i3 to display the price of certain coins and their rise/fall in the past five minutes. It is basically a go port of the polybar-crypto code base.

The track sub-command has a flag that needs to be set. The --coin, or -c for short, will allow you to specify which coins you wish to display.

crypto track --coin btc,eth

BTC £26332.21 | -2.57%   ETH £905.26 | -0.8%

Graph

Graph uses the same data set to display a coin in an ascii graph in the terminal. This command utilises asciigraph, which does all the heavy lifting.

The graph sub-command requires you to specify a coin using the --coin or -c flag followed by a coin of your choice, for example:

crypto graph --coin btc -H 10

The -H or --height flag allows you to specify the height of the graph displayed.
