Feature: Rule statement
Scenario: Run a rule without any input
Given a file named "build.ninja" with:
"""
rule hello
command = echo hello
build foo: hello
"""
When I successfully run `turtle`
Then the stdout should contain exactly "hello"
Scenario: Run a rule with an input
Given a file named "build.ninja" with:
"""
rule hello
command = echo hello
build foo: hello bar
"""
And a file named "bar" with ""
When I successfully run `turtle`
Then the exit status should be 0
Scenario: Fail to run a rule with a missing input
Given a file named "build.ninja" with:
"""
rule hello
command = echo hello
build foo: hello bar
"""
When I run `turtle`
Then the exit status should not be 0
Scenario: Run a rule with an input variable
Given a file named "build.ninja" with:
"""
rule echo
command = echo $in
build foo: echo bar
"""
And a file named "bar" with ""
When I successfully run `turtle`
Then the stdout should contain exactly "bar"
Scenario: Run a rule with an output variable
Given a file named "build.ninja" with:
"""
rule echo
command = echo $out
build foo: echo bar
"""
And a file named "bar" with ""
When I successfully run `turtle`
Then the stdout should contain exactly "foo"
Scenario: Run a rule with a custom variable
Given a file named "build.ninja" with:
"""
rule echo
command = echo $x
build foo: echo
x = hello
"""
And a file named "bar" with ""
When I successfully run `turtle`
Then the stdout should contain exactly "hello"
Scenario: Run a rule with two custom variables
Given a file named "build.ninja" with:
"""
rule echo
command = echo $x $y
build foo: echo
x = hello
y = world
"""
And a file named "bar" with ""
When I successfully run `turtle`
Then the stdout should contain exactly "hello world"
Scenario: Run a phony rule
Given a file named "build.ninja" with:
"""
rule touch
command = touch $out
build foo: touch
build bar: phony foo
default bar
"""
When I successfully run `turtle`
Then the file named "foo" should exist
Scenario: Use a phony dependency
Given a file named "build.ninja" with:
"""
rule touch
command = touch $out
build foo: touch
build bar: phony foo
build baz: touch bar
default baz
"""
When I successfully run `turtle`
Then the file named "foo" should exist
Scenario: Rebuild for a phony dependency
Given a file named "build.ninja" with:
"""
rule hello
command = echo hello && touch $out
build foo: phony
build bar: hello foo
default bar
"""
When I successfully run `turtle`
And I successfully run `turtle`
Then the stdout should contain exactly:
"""
hello
hello
"""
