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

Handles variable substitutions for args.
|
|
|
|
Args:
|
|
name: Name of the rule.
|
|
out: Path of the output file, relative to this package.
|
|
args: Arguments to concatenate into a params file.
|
|
|
|
- Subject to 'Make variable' substitution. See https://docs.bazel.build/versions/main/be/make-variables.html.
|
|
|
|
- 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 $(location) substitution returns the manifest file path which differs from the `*_binary` & `*_test`
|
|
args and genrule bazel substitutions. This will be fixed in a future major release.
|
|
See docs string of `expand_location_into_runfiles` macro in `internal/common/expand_into_runfiles.bzl`
|
|
for more info.
|
|
|
|
- Subject to predefined variables & custom variable substitutions.
|
|
|
|
Predefined "Make" variables such as `$(COMPILATION_MODE)` and `$(TARGET_CPU)` are expanded.
|
|
See https://docs.bazel.build/versions/main/be/make-variables.html#predefined_variables.
|
|
|
|
Custom variables are also expanded including variables set through the Bazel CLI with `--define=SOME_VAR=SOME_VALUE`.
|
|
See https://docs.bazel.build/versions/main/be/make-variables.html#custom_variables.
|
|
|
|
Predefined genrule variables are not supported in this context.
|
|
|
|
data: Data for `$(location)` expansions in args.
|
|
newline: Line endings to use. One of [`"auto"`, `"unix"`, `"windows"`].
|
|
|
|
- `"auto"` for platform-determined
|
|
- `"unix"` for LF
|
|
- `"windows"` for CRLF
