Crystal.
## build/install
```
git clone https://github.com/jethrodaniel/z && cd z && make
```
## usage
```
$ ./bin/z
Usage: z [command] [arguments]
lex Lex input, output tokens
parse Parse input, output AST
dot Parse input, output graphviz dot
compile Compile input, output assembly
run Compile and run input
obj Analyze object files
-i Get input from stdin
-c Get input from string
-v, --version Show the version
-h, --help Show this help
```
## example
See the specs in the [spec/compiler directory](spec/compiler).
```
$ pushd spec/compiler/
$ ../../bin/z run hi.c
hi!
$ ../../bin/z run main.c
fib(0) = 0
fib(1) = 1
fib(2) = 1
fib(3) = 2
fib(4) = 3
fib(5) = 5
fib(6) = 8
fib(7) = 13
fib(8) = 21
fib(9) = 34
fib(10) = 55
fib(11) = 89
fib(12) = 144
$ z run -c 'p(c){putchar(c);}main(){p(65);p(10);}'
