Shell rules

Shell rules for the Please build system

Usage

The easiest way to get set up is to run plz init plugin shell. This will install the plugin and automatically make the shell rules available in every BUILD file.

Alternatively add the following to plugins/BUILD:

plugin_repo(
  name = "shell",
  version = <latest version here>,
)

And add the following to your .plzconfig:

[Plugin "shell"]
Target = //plugins:shell

And then use subinclude("///shell//build_defs:shell") to make the rules available in a BUILD file.

sh_cmd()

The sh_cmd() rule can be used to run a bash command:

subinclude("///shell//build_defs:shell")

sh_cmd(name="hello_world", cmd="echo Hello, world!")

$ plz run //:hello_world
Hello, world!

sh_binary()

The sh_binary() rules is similar to sh_cmd() however it takes in a .sh file as a source:

subinclude("///shell//build_defs:shell")

sh_binary(
  name = "hello_world",
  srcs = ["hello.sh"],
)

And then add hello.sh:

#!/bin/bash

echo Hello, world!

$ plz run //:hello_world
Hello, world!

sh_test()

The sh_rule() works the same as sh binary, but can provide a test. The .sh file must indicate success or failure via the exit code:

sh_test(
  name = "test",
  src = "test.sh",
)

#!/bin/bash

echo "failure"
exit 1
