Generates a UTF-8 encoded params file from a list of arguments.

Handles variable substitutions for args.


### **Parameters**


| Name  | Description | Default Value |
| :------------- | :------------- | :------------- |
| <a id="params_file-name"></a>name |  Name of the rule.   |  none |
| <a id="params_file-out"></a>out |  Path of the output file, relative to this package.   |  none |
| <a id="params_file-args"></a>args |  Arguments to concatenate into a params file.  Subject to 'Make variable' substitution. See https://docs.bazel.build/versions/main/be/make-variables.html.  <ol> <li> Subject to predefined source/output path variables substitutions.  The predefined variables `execpath`, `execpaths`, `rootpath`, `rootpaths`, `location`, and `locations` take label parameters (e.g. `$(execpath //foo:bar)`) and substitute the file paths denoted by that label.  See https://docs.bazel.build/versions/main/be/make-variables.html#predefined_label_variables for more info.  NB: This $(location) substition returns the manifest file path which differs from the `*_binary` & `*_test` args and genrule bazel substitions. This will be fixed in a future major release. See docs string of `expand_location_into_runfiles` macro in `internal/common/expand_into_runfiles.bzl` for more info.</li>  <li>Subject to predefined variables & custom variable substitutions.  Predefined "Make" variables such as `$(COMPILATION_MODE)` and `$(TARGET_CPU)` are expanded. See https://docs.bazel.build/versions/main/be/make-variables.html#predefined_variables.  Custom variables are also expanded including variables set through the Bazel CLI with `--define=SOME_VAR=SOME_VALUE`. See https://docs.bazel.build/versions/main/be/make-variables.html#custom_variables.  Predefined genrule variables are not supported in this context.</li> </ol>   |  <code>[]</code> |
| <a id="params_file-data"></a>data |  Data for <code>$(location)</code> expansions in args.   |  <code>[]</code> |
| <a id="params_file-newline"></a>newline |  Line endings to use. One of [`"auto"`, `"unix"`, `"windows"`].  <ul> <li>`"auto"` for platform-determined</li> <li>`"unix"` for LF</li> <li>`"windows"` for CRLF</li> </ul>   |  <code>"auto"</code> |
| <a id="params_file-kwargs"></a>kwargs |  undocumented named arguments   |  none |
