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.

@ and - are sort of odd ducks. I added them because make supports them, but I'm not totally sure that it's a good idea to more.

I was thinking of a prefix that would go before the indentation, not after it.

I lean more and more towards just using just as the argument parser and then storing most/all code in bash scripts. That way, you don't lose out on just lacking file inclusion support, and you don't have to worry about this feature either (being able to run other recipes). It's not 100% as elegant as just doing everything, but without file-inclusion support there's not much to do anyway. But yeah, perhaps it would still make sense to add this feature 🤷

Has any progress been made on this? I just (pun not intended) started using just, and this was one of the first things I tried to do. just --justfile {{justfile()}} foo doesn't work reliably because the user invoking the recipe may not have just installed globally (i.e. npm install -D just-install), or have it installed under a different name (i.e. npm install -g rust-just). Maybe something like {{justexecutable()}} --justfile {{justfile()}} foo could work if there's not already a solution?

EDIT: Just found https://github.com/casey/just?tab=readme-ov-file#just-executable

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
