Imports
One justfile
can include the contents of another using import
statements.
If you have the following justfile
:
import 'foo/bar.just'
a: b
@echo A
And the following text in foo/bar.just
:
b:
@echo B
foo/bar.just
will be included in justfile
and recipe b
will be defined:
$ just b
B
$ just a
B
A
The import
path can be absolute or relative to the location of the justfile
containing it. A leading ~/
in the import path is replaced with the current
users home directory.
Justfiles are insensitive to order, so included files can reference variables
and recipes defined after the import
statement.
Imported files can themselves contain import
s, which are processed
recursively.
When allow-duplicate-recipes
is set, recipes in parent modules override
recipes in imports. In a similar manner, when allow-duplicate-variables
is
set, variables in parent modules override variables in imports.
Imports may be made optional by putting a ?
after the import
keyword:
import? 'foo/bar.just'
Importing the same source file multiple times is not an error1.37.0.
This allows importing multiple justfiles, for example foo.just
and
bar.just
, which both import a third justfile containing shared recipes, for
example baz.just
, without the duplicate import of baz.just
being an error:
# justfile
import 'foo.just'
import 'bar.just'
# foo.just
import 'baz.just'
foo: baz
# bar.just
import 'baz.just'
bar: baz
# baz
baz:
