# racket-makefile

`racket-makefile` is a small `#lang` for make-style builds. It keeps ordinary
Racket available and only adds targets, dependencies, timestamp based rebuilds,
phony targets, external command execution and a few cleanup helpers.

```racket
#lang racket-makefile

(define CC 'cc)
(define CFLAGS '(-Wall -O2))

(default-target all)
(phony all clean)

(target all
  (deps "hello"))

(target "hello"
  (deps "hello.c")
  (run `(,CC ,@CFLAGS -o $target $<)))

(target clean
  (rm-f "hello")
  (rm-rf "compiled")
  (cleanup "scrbl" '("**.html" "**.js" "**.css")))
```

Install a local checkout with:

```text
raco pkg install
```

For a versioned archive, give the package name explicitly:

```text
raco pkg install --name racket-makefile racket-makefile-0.1.1.zip
```

Run the default target or select one or more targets explicitly:

```text
racket Makefile.rkt
racket Makefile.rkt clean
racket Makefile.rkt clean all
```

The language adds `target`, `deps`, `phony`, `default-target`, `run`, `rm-f`,
`rm-rf`, `cleanup`, `$target`, `$deps` and `$<`. Dependency expressions may
also produce lists, which are automatically flattened. Everything else is
ordinary Racket.

See the installed `racket-makefile` Scribble documentation for the full API.
