</pre>

The runfiles manifest entry path for a file

This is the full runfiles path of a file including its workspace name as
the first segment. We refert to it as the manifest path as it is the path
flavor that is used for in the runfiles MANIFEST file.

We must avoid using non-normalized paths (workspace/../other_workspace/path)
in order to locate entries by their key.

## to_workspace_path

<pre>
to_workspace_path(<a href="#to_workspace_path-ctx">ctx</a>, <a href="#to_workspace_path-file">file</a>)
</pre>

The workspace relative path for a file

This is the full runfiles path of a file excluding its workspace name.
This differs from root path and manifest path as it does not include the
repository name if the file is from an external repository.

| :------------- | :------------- | :------------- |
| <a id="to_workspace_path-ctx"></a>ctx |  starlark rule execution context   |  none |
