Feature: Variable definition
Scenario: Expand a variable on definition
Given a file named "build.ninja" with:
"""
x = hello
y = $x
x = world
rule echo
command = echo $y
build foo: echo
"""
When I successfully run `turtle`
Then the stdout should contain exactly "hello"
Scenario: Expand a nested variable
Given a file named "build.ninja" with:
"""
x = hello
y = $x world
rule echo
command = echo $y
build foo: echo
"""
When I successfully run `turtle`
Then the stdout should contain exactly "hello world"
Scenario: Append a value to a variable
Given a file named "build.ninja" with:
"""
x = hello
x = $x world
rule echo
command = echo $x
build foo: echo
"""
When I successfully run `turtle`
Then the stdout should contain exactly "hello world"
Scenario: Escape dollar signs in a variable
Given a file named "build.ninja" with:
"""
x = $$y $$$$
rule echo
command = echo '$x'
build foo: echo
"""
When I successfully run `turtle`
Then the stdout should contain exactly "$y $$"
Scenario: Escape a space and colon in a variable
Given a file named "build.ninja" with:
"""
x = a$ b$:c
rule echo
command = echo '$x'
build foo: echo
"""
When I successfully run `turtle`
Then the stdout should contain exactly "a b:c"
Scenario: Escape a newline in a variable
Given a file named "build.ninja" with:
"""
x = hello $
world
rule echo
command = echo $x
build foo: echo
"""
When I successfully run `turtle`
Then the stdout should contain exactly "hello world"
Scenario: Define a variable prefixed with a keyword
Given a file named "build.ninja" with:
"""
default_message = hello
rule echo
command = echo $default_message
build foo: echo
"""
When I successfully run `turtle`
Then the stdout should contain exactly "hello"
Scenario: Expand variables in build paths
Given a file named "build.ninja" with:
"""
directory = foo
rule touch
command = touch $out
build $directory/bar ${directory}/baz: touch
default $directory/bar
"""
When I successfully run `turtle`
Then the file named "foo/bar" should exist
And the file named "foo/baz" should exist
