The command "just eval "${code}"" is using the "eval" command in the "just" environment.
- "just" is a command runner and task execution tool, similar to GNU Make, used in task automation.
- "eval" is a shell command used to evaluate and execute a command or set of commands provided as an argument.
In this command, the variable "code" is being passed to the command as an argument. The syntax "${code}" is used to expand the value of the variable "code". It assumes that "code" contains a valid shell command or set of commands.
Once the variable expansion is done, the "eval" command executes the resulting command(s) in the current shell environment. This means that the commands represented by the value of the "code" variable will be interpreted and run as if they were typed directly in the command line.
Overall, the command "just eval "${code}"" is used to evaluate and execute the value stored in the "code" variable as a shell command, providing flexibility in dynamically running commands.
