|
A rule that copies source files to the output tree.
|
|
|
|
This rule uses a Bash command (diff) on Linux/macOS/non-Windows, and a cmd.exe
|
|
command (fc.exe) on Windows (no Bash is required).

## copy_file_to_bin_action
|
|
|
|
<pre>
|
|
copy_file_to_bin_action(<a href="#copy_file_to_bin_action-ctx">ctx</a>, <a href="#copy_file_to_bin_action-file">file</a>)
|
|
</pre>
|
|
|
|
Factory function that creates an action to copy a file to the output tree.
|
|
|
|
File are copied to the same workspace-relative path. The resulting files is
|
|
returned.
|
|
|
|
If the file passed in is already in the output tree is then it is returned
|
|
without a copy action.
|
|
|
|
To use `copy_file_to_bin_action` in your own rules, you need to include the toolchains it uses
|
|
in your rule definition. For example:
|
|
|
|
```starlark
|
|
load("@aspect_bazel_lib//lib:copy_to_bin.bzl", "COPY_FILE_TO_BIN_TOOLCHAINS")
|
|
|
|
my_rule = rule(
|
|
...,
|
|
toolchains = COPY_FILE_TO_BIN_TOOLCHAINS,
|
|
)
|
|
```
|
|
|
|
Additionally, you must ensure that the coreutils toolchain is has been registered in your
|
|
WORKSPACE if you are not using bzlmod:
|
|
|
|
```starlark
|
|
load("@aspect_bazel_lib//lib:repositories.bzl", "register_coreutils_toolchains")
|
|
|
|
register_coreutils_toolchains()
|
|
```

</pre>
|
|
|
|
Factory function that creates actions to copy files to the output tree.
|
|
|
|
Files are copied to the same workspace-relative path. The resulting list of
|
|
files is returned.
|
|
|
|
If a file passed in is already in the output tree is then it is added
|
|
directly to the result without a copy action.

List of File objects in the output tree.

## copy_to_bin
|
|
|
|
<pre>
|
|
copy_to_bin(<a href="#copy_to_bin-name">name</a>, <a href="#copy_to_bin-srcs">srcs</a>, <a href="#copy_to_bin-kwargs">kwargs</a>)
|
|
</pre>
|
|
|
|
Copies a source file to output tree at the same workspace-relative path.
|
|
|
|
e.g. `<execroot>/path/to/file -> <execroot>/bazel-out/<platform>/bin/path/to/file`
|
|
|
|
If a file passed in is already in the output tree is then it is added directly to the
|
|
DefaultInfo provided by the rule without a copy.
|
|
|
|
This is useful to populate the output folder with all files needed at runtime, even
|
|
those which aren't outputs of a Bazel rule.
|
|
|
|
This way you can run a binary in the output folder (execroot or runfiles_root)
|
|
without that program needing to rely on a runfiles helper library or be aware that
|
|
files are divided between the source tree and the output tree.
