In a Starlark file that's being used in Bazel, if I create a file with ctx.actions.declare_file(), is there some way to associate dependencies/datafiles/runfiles with it? For example:

I can create and write to a file:

script_file = ctx.actions.declare_file("myscript.sh")
ctx.actions.write(
 script_file,
 "echo hello from myscript.shn",
 is_executable = True
)

... and then I can use script_file any way I want. E.g. in ctx.actions.run or ctx.actions.run_shell.

Now suppose myscript.sh depends on data.txt:

data_file = ctx.actions.declare_file("data.txt")
ctx.actions.write(data_file, "hello from data.txtn")

script_file = ctx.actions.declare_file("myscript.sh")
ctx.actions.write(
 script_file,
 "cat n".format(data_file.path),
 is_executable = True
)

And then I can run it (in this example, the rule that called this has an output named "main"):

ctx.actions.run_shell(
 tools = [script_file, data_file],
 outputs = [ctx.outputs.main],
 command = " > ".format(script_file.path, ctx.outputs.main.path)
)

Okay. But really it's messy to have to specify both script_file and data_file in the tools array. I would like to specify just script_file, and have the data_file be automatically picked up as a runfile of script_file.

Is there a way to that? If so, how? If not, is there some other, better way for me to be approaching this?
