bazelbazelrc

User name in .bazelrc

I would like to add this to my .bazelrc, but the $(whoami) doesn't expand like if it was in a shell.

startup --output_user_root=/tmp/bazel/out/$(whoami)

It produces the literal result:

/tmp/bazel/out/$(whoami)/faedb999bdce730c9c495251de1ca1a4/execroot/__main__/bazel-out/

Is there any way to do what I want: adding a name/hash to the option in the .bashrc file?

Edit: what I really want is to set the outputRoot to /tmp/bazel/out without using an environment variable and to let bazel create it's user and workspace hash directories there.

Solution

  • You can run Bazel from a wrapper script. In fact, that's exactly what the bazel binary is (at least on Linux): it's a wrapper script that calls bazel-real. You can edit this wrapper script if you like, or rename it to bazel.sh and write your own wrapper.
