asnap

Cardano address snap utility.

Asnap is a tool that uses cardano-cli to query a bunch of addresses, puts that information in a data-structure, and then applies a text-template of your choice to it, to produce the desired output. The text template can be one of the built-in ones, or you can write your own.

Install

go install gitlab.com/wmoco/asnap@latest

And make sure that $HOME/go/bin is in your PATH!

Developed and tested on linux, running cardano node 1.34.1 in a nix-shell.

Standard use

$ asnap mediator.address buyer.address seller.address

(note: as of v0.1.3 the default template shown is 'top' and no longer 'std').

Custom template

$ cat t402.tpl 

«range .Alias2AddressMap.seller.TxixList»«if .FlagGreatestPureAda»  --tx-in-collateral «.Txix» \ 
«end»«end»«range .Alias2AddressMap.payout.TxixList»«if gt .AggregateLovelace 3000001»  --tx-in «.Txix» \
«end»«end»«range .Alias2AddressMap.seller.TxixList»  --tx-in «.Txix» \
«end» 

When applying the above template (contained in file t402.tpl) to these addresses:

$ asnap -f t402.tpl mediator.address buyer.address seller.address contract.address payout.address 

You get this output:
