#### Outside Recipe Bodies
|
||||
|
||||
Parenthesized expressions can span multiple lines:
|
||||
|
||||
```just
|
||||
abc := ('a' +
|
||||
'b'
|
||||
+ 'c')
|
||||
|
||||
abc2 := (
|
||||
'a' +
|
||||
'b' +
|
||||
'c'
|
||||
)
|
||||
|
||||
foo param=('foo'
|
||||
+ 'bar'
|
||||
):
|
||||
echo {{param}}
|
||||
|
||||
bar: (foo
|
||||
'Foo'
|
||||
)
|
||||
echo 'Bar!'
|
||||
```
|
||||
|
||||
Lines ending with a backslash continue on to the next line as if the lines were joined by whitespace<sup>1.15.0</sup>:
|
||||
|
||||
```just
|
||||
a := 'foo' + \
|
||||
'bar'
|
||||
|
||||
foo param1 \
|
||||
param2='foo' \
|
||||
*varparam='': dep1 \
|
||||
(dep2 'foo')
|
||||
echo {{param1}} {{param2}} {{varparam}}
|
||||
|
||||
dep1: \
|
||||
# this comment is not part of the recipe body
|
||||
echo 'dep1'
|
||||
|
||||
dep2 \
|
||||
param:
|
||||
echo 'Dependency with parameter {{param}}'
|
||||
```
|
||||
|
||||
Backslash line continuations can also be used in interpolations. The line following the backslash must start with the same indentation as the recipe body, although additional indentation is accepted.
|
||||
|
||||
```just
|
||||
recipe:
|
||||
echo '{{ \
|
||||
"This interpolation " + \
|
||||
"has a lot of text." \
|
||||
}}'
|
||||
echo 'back to recipe body'
|
||||
```
|
||||

||||
