selects.with_or

selects.with_or(input_dict, no_match_error)

Drop-in replacement for select() that supports ORed keys.

Example:

  ```build
  deps = selects.with_or({
      "//configs:one": [":dep1"],
      ("//configs:two", "//configs:three"): [":dep2or3"],
      "//configs:four": [":dep4"],
      "//conditions:default": [":default"]
  })
  ```

  Key labels may appear at most once anywhere in the input.

Parameters

input_dict	required. The same dictionary `select()` takes, except keys may take either the usual form `"//foo:config1"` or `("//foo:config1", "//foo:config2", ...)` to signify `//foo:config1` OR `//foo:config2` OR `...`.
no_match_error	optional. default is "" Optional custom error to report if no condition matches.

selects.with_or_dict

selects.with_or_dict(input_dict)

Variation of with_or that returns the dict of the select().

Unlike select(), the contents of the dict can be inspected by Starlark macros.

Parameters

input_dict

required. Same as `with_or`.

selects.config_setting_group

selects.config_setting_group(name, match_any, match_all)

Matches if all or any of its member config_settings match.

Example:

config_setting(name = "one", define_values = {"foo": "true"})
config_setting(name = "two", define_values = {"bar": "false"})
config_setting(name = "three", define_values = {"baz": "more_false"})

config_setting_group(
    name = "one_two_three",
    match_all = [":one", ":two", ":three"]
)

cc_binary(
    name = "myapp",
    srcs = ["myapp.cc"],
    deps = select({
        ":one_two_three": [":special_deps"],
        "//conditions:default": [":default_deps"]
    })

Parameters

name	required. The group's name. This is how `select()`s reference it.
match_any	optional. default is [] A list of `config_settings`. This group matches if *any* member in the list matches. If this is set, `match_all` must not be set.
match_all	optional. default is [] A list of `config_settings`. This group matches if *every* member in the list matches. If this is set, `match_any` must be not set.
