15*bcb5dc79SHONG Yifan"""A rule that writes a UTF-8 encoded text file from user-specified contents.
16*bcb5dc79SHONG Yifan
17*bcb5dc79SHONG Yifannative.genrule() is sometimes used to create a text file. The 'write_file' and
18*bcb5dc79SHONG Yifanmacro does this with a simpler interface than genrule.
19*bcb5dc79SHONG Yifan
20*bcb5dc79SHONG YifanThe rules generated by the macro do not use Bash or any other shell to write the
21*bcb5dc79SHONG Yifanfile. Instead they use Starlark's built-in file writing action
22*bcb5dc79SHONG Yifan(ctx.actions.write).
