- runAppBinary registers SIGINT and SIGTERM after its build and recursion checks and runChild forwards each signal to the app binary, then waits for it to exit, so stopping summer serve frees the port (WR-08) - newAppCmd keeps the inherited stdin, env and output, and a context cancel sends SIGTERM with a 15-second appShutdownGrace before SIGKILL - the child stays in summer's process group so the admin password prompts can read the terminal - helper-process tests cover SIGINT, SIGTERM and context cancel - console introduction notes the signal forwarding

| Console introduction | The two command-line programs of SummerCMS, the summer developer tool and the application binary, and how summer delegates runtime commands. | console | 10 |
Console introduction
WinterCMS has one console entry point, php artisan. SummerCMS has two programs, because the developer tooling and the running application are separate binaries:
| Program | Where it comes from | What it does |
|---|---|---|
summer |
Installed once, by the curl -fsSL https://summercms.io/new | bash -s -- <name> one-liner or from a framework checkout with go install ./cmd/summer. |
Creates, builds and watches applications, scaffolds plugins and their parts, records API parity fixtures and builds these docs. |
The application binary, for example ./bin/acme |
Written by summer build into the application's bin/ directory. |
Runs the application: the HTTP server, migrations, workers, the scheduler, admin accounts and every command its plugins add. |
The application binary is what you deploy, so everything that must run in production, such as migrations and workers, is a command of the binary rather than of summer.
Getting help
Both programs list their commands with --help, and every command accepts --help for its arguments and flags:
summer --help
summer make:model --help
./bin/acme --help
./bin/acme migrate:rollback --help
A command that summer delegates to the application binary, such as summer serve, answers --help with the binary's own help, so run it inside an application directory. Asking the help command of summer about a delegated command instead prints a short description and its common flags without running the binary.
Commands that summer delegates
During development you often work from the application directory with summer alone. These summer commands find the application's summer.yaml, build bin/<binary> when it does not exist yet, and run the same command of the binary with the same arguments:
| summer command | Runs |
|---|---|
summer migrate |
./bin/acme migrate |
summer migrate:rollback |
./bin/acme migrate:rollback |
summer migrate:status |
./bin/acme migrate:status |
summer serve |
./bin/acme serve |
summer queue:work |
./bin/acme queue:work |
summer queue:clear |
./bin/acme queue:clear |
summer schedule:run |
./bin/acme schedule:run |
summer route:list |
./bin/acme route:list |
summer key:generate |
./bin/acme key:generate |
summer admin:create |
./bin/acme admin:create |
summer admin:reset-password |
./bin/acme admin:reset-password |
summer parses no flags of these commands: every flag and argument, including --help, goes to the binary unchanged, and the binary's input is your terminal, so the password prompts of admin:create and admin:reset-password work as usual:
summer serve --addr 127.0.0.1:8123
summer serve --help
summer migrate:rollback --plugin acme.blog
summer admin:create --email admin@example.com --superuser
One leading -- is ignored, so summer serve -- --addr 127.0.0.1:8123 behaves the same as summer serve --addr 127.0.0.1:8123.
When summer receives SIGINT or SIGTERM while the binary runs, it passes the signal on and waits for the binary to shut down, so stopping summer serve with Ctrl+C or kill frees its port.
summer does not rebuild an existing binary before it delegates. Run summer build after you change code, or keep summer dev running. Every other runtime command, such as deferred:purge or the commands your plugins add, is run on the binary directly.
