Description
This PR refactors the error handling in the file download process to provide a more robust and flexible error handling mechanism.
Summary of Changes
dl.go
:DlTo
method of theGHReleaseDl
struct with an error return. This ensures that errors during the file download process are returned to the caller function instead of abruptly stopping the program execution.ghdl/main.go
:Run
function of therootCmd
variable to handle the error returned by theDlTo
method. If an error is returned, an error message is printed and the program exits with a non-zero status code.These changes improve the code's reliability and maintainability by providing a more controlled and predictable error handling mechanism.
