View Source mix run (Mix v1.16.0)
Runs the current application.
mix run starts the current application dependencies and the
application itself. The application will be compiled if it has
not been compiled yet or it is outdated.
mix run may also run code in the application context through
additional options. For example, to run a script within the
current application, you may pass a filename as argument:
$ mix run my_app_script.exs arg1 arg2 arg3
Code to be executed can also be passed inline with the -e option:
$ mix run -e "DbUtils.delete_old_records()" -- arg1 arg2 arg3
In both cases, the command-line arguments for the script or expression
are available in System.argv/0. This mirror the command line interface
in the elixir executable.
For starting long running systems, one typically passes the --no-halt
option:
$ mix run --no-halt
The --no-start option can also be given and the current application,
nor its dependencies will be started. Alternatively, you may use
mix eval to evaluate a single expression without starting the current
application.
If you need to pass options to the Elixir executable at the same time
you use mix run, it can be done as follows:
$ elixir --sname hello -S mix run --no-halt
This task is automatically re-enabled, so it can be called multiple times with different arguments.
