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 imports, which are processed
recursively.
When allow-duplicate-recipes is set, recipes in parent modules override
recipes in imports.
Imports may be made optional by putting a ? after the import keyword:
import? 'foo/bar.just'
Missing source files for optional imports do not produce an error.
