Skylib module containing convenience interfaces for select().
|
|
|
|
<a id="selects.with_or"></a>
|
|
|
|
## selects.with_or
|
|
|
|
<pre>
|
|
selects.with_or(<a href="#selects.with_or-input_dict">input_dict</a>, <a href="#selects.with_or-no_match_error">no_match_error</a>)
|
|
</pre>
|
|
|
|
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**
|
|
|
|
|
|
| Name | Description | Default Value |
|
|
| :------------- | :------------- | :------------- |
|
|
| <a id="selects.with_or-input_dict"></a>input_dict | The same dictionary <code>select()</code> takes, except keys may take either the usual form <code>"//foo:config1"</code> or <code>("//foo:config1", "//foo:config2", ...)</code> to signify <code>//foo:config1</code> OR <code>//foo:config2</code> OR <code>...</code>. | none |
|
|
| <a id="selects.with_or-no_match_error"></a>no_match_error | Optional custom error to report if no condition matches. | <code>""</code> |
|
|
|
|
**RETURNS**
|
|
|
|
A native `select()` that expands
|
|
|
|
`("//configs:two", "//configs:three"): [":dep2or3"]`
|
|
|
|
to
|
|
|
|
```build
|
|
"//configs:two": [":dep2or3"],
|
|
"//configs:three": [":dep2or3"],
|
|
```
|
|
|
|
|
|
<a id="selects.with_or_dict"></a>
|
|
|
|
## selects.with_or_dict
|
|
|
|
<pre>
|
|
selects.with_or_dict(<a href="#selects.with_or_dict-input_dict">input_dict</a>)
|
|
</pre>
|
|
|
|
Variation of `with_or` that returns the dict of the `select()`.
|
|
|
|
Unlike `select()`, the contents of the dict can be inspected by Starlark
|
|
macros.
|
|

|
| Name | Description | Default Value |

|
|
|
|
**RETURNS**

|
|
A dictionary usable by a native `select()`.
|

|
|
|
|
## selects.config_setting_group
|
|
|
|
<pre>

selects.config_setting_group(<a href="#selects.config_setting_group-name">name</a>, <a href="#selects.config_setting_group-match_any">match_any</a>, <a href="#selects.config_setting_group-match_all">match_all</a>, <a href="#selects.config_setting_group-visibility">visibility</a>)
|

</pre>
|
|
|
|
Matches if all or any of its member `config_setting`s match.

|
|
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"],
