stack: Compile a project and execute a command after compilation.

stack

$ stack build --exec "${command}"

try on your machine

This command is used in the context of building a project using the Stack build tool. Let's break it down:

stack build is a command used to build or compile a Haskell project. It builds the project based on the information provided in the stack.yaml file.
--exec is an option/flag used with stack build to specify an executable or command to be executed after the project is successfully built.
"${command}" represents the value that should be provided for the --exec flag. It is a placeholder and should be replaced with the actual command you want to run.

So, when you run stack build --exec "${command}", Stack will build the project and then execute the command specified in place of ${command}. This can be helpful if you want to perform additional tasks or execute certain commands automatically after the project is built.

This explanation was created by an AI. In most cases those are correct. But please always be careful and never run a command you are not sure if it is safe.
