Installing the command-line executable

Assuming you have Rust/Cargo installed, run this command in a terminal:

cargo install ldenv

It will make the ldenv command available in your PATH if you've allowed the PATH to be modified when installing Rust. cargo uninstall ldenv uninstalls.

Back to the crate overview.

Readme

ldenv

Uses dotenvy but uses mode files

By default the mode is local and it will load in order

.env.local
.env

and so .env.local has priority

By default if no mode is provided on the command line, it will get the mode from the environment variable MODE

you can specify a different env variable to get the default mode via -a /sy -n <env variable name>

And you can specify the mode directly via -m <mode>

for example with with ldenv -m production env

it will load the following in order

.env.production.local
.env.production
.env

and execute the command env

Parsing

[preffix]@@<env names>[@:<default value>][@:<suffix>]

Examples for the parse:

target/debug/ldenv echo @@RPC_URL_:MODE:,RPC_URL@:http://localhost:8545@: @@ localhost

This will load localhost as MODE and will try to fetch RPC_URL_<MODE> as env variable, falling bacon RPC_URL or default to http://localhost:8545
