Install

You can install the numscript cli with one of the following ways:

​
Using curl

For Mac and Unix: 
curl -sSf https://raw.githubusercontent.com/formancehq/numscript/main/install.sh | bash

​
Using golang toolchain

go install github.com/formancehq/numscript/cmd/numscript@latest

​
Check

You can use the numscript check command to run static analysis on a numscript program. The static analysis includes parsing errors, wrong variables or types usage, as well as more advanced checks on numscript constructs. You can use it this way: 
numscript check my-file.num
The command will exit with an error status code if there is at least one error or warning.

​
Run

Available from [email protected]
You can use the CLI to run local scripts (mostly intended for local prototyping). For example, given this script:
my-script.num
vars {
  monetary $amt  
}

send $amt (
  source = @alice
  destination = @world
)
And this inputs file (which has to have the same name of the numscript file, plus the .inputs.json suffix):
my-script.num.inputs.json
{
  "variables": {
    "amt": "USD/2 100"
  },
  "balances": {
    "alice": { "USD/2": 9999 }
  }
}
You can run the file using: 
numscript run my-script.num
You’ll see the postings: 
Postings:
| Source | Destination | Asset | Amount |
| alice  | world       | USD/2 | 100    |

Test

You can use the numscript test to check that the specs given in a numscript specs format file are valid for a given numscript. For example: 
numscript test src/domain/numscript
This will look into all the src/domain/numscript folder to find all the <file>.num that have a corresponding <file>.num.specs.json specs file
