Is it possible to pass a default constructor argument for my canister into dfx.json, so that when I simply call dfx deploy, that argument is passed in without specifying it? Example: “mycanister”:{ “main”:“src/mycanister.mo”, “type”:“motoko”, “argument”:"(12345)" } Is this something that coul…

Do we have a documentation on all the possible entries of dfx.json and what we can achieve with different entries in dfx.json. Please can someone point us to the documentation/resource if any?

While not quite what was asked, the zx “CLI devops scripting” tool might be useful to do this and some other things (like automatically switch which system-wide networks.json configuration is used ( @jorgenbuilder )). Eg: dfxd.mjs #!/usr/bin/env z import { argv, chalk } from "zx"; import { spawnSyn…

Is there by now an option available to specify deploy arguments in the dfx.json file? Something like what was described here .
