Run other recipe?

[fgblomqvist]

If I have a file like:

foo:
  echo foo

bar:
  echo bar
  foo

It will error because there is no such command as foo. Makes sense. But how can I call a recipe from another? I don't want to have to use just foo since working directory etc. isn't guaranteed.

It isn't very pretty, but you can do:

foo:
  echo foo

bar:
  echo bar
  just --justfile {{justfile()}} foo

(-f can also be used instead of --justfile.)

This has come up a few times before, so ideally there would be a nice way to do this without such hackery.

[sociopart]

Since nothing was done until now, you can evolve this hackery by using variables:

call_recipe := just_executable() + " --justfile=" + justfile()

bar:
  @echo "test"

foo:
  {{call_recipe}} bar

But more proper solution would be fine. Mostly it might help for interacting with private recipes.

From the cross-platform.just example, it looks like there is a && syntax that works:

second:
  @echo "second"

first: && second
  @echo "first"

$ just second
second

$ just first
first
second

The && syntax only seems to work for a single recipe.

For me (just version 1.38.0), this works:

validate: && validate-this
    echo "Done."

validate-this:
    echo "Validating this."

But this does not:

validate: && validate-this && validate-that
    echo "Done."

validate-this:
    echo "Validating this."

validate-that:
    echo "Validating that."

[casey]

All recipes after && will be subsequents, so you only need one:

validate: && validate-this validate-that
    echo "Done."

@casey thanks, that works for me!

[GitToby]

just for further clarification, the && separates the "pre" and "post" commands. Remember the @ symbol suppresses the printing of the command.

before1:
    @echo 1

before2 my_var="2":
    @echo {{my_var}}

after1:
    @echo a

after2 my_var="b":
    @echo {{my_var}}

cmd: before1 before2 && after1 (after2 "c")
    @echo "hello world"

prints

1
2
hello world
a
c
