# //// per-device configuration //////////////////////////////// <dev-pre> // #

# Per-device configuration is kept here in dotfiles.git too, but it won't be
# activated just by linking .zshrc. You also need to link ~/.device_pre and
# ~/.device_post to the relevant per-device files under `device`.

# All exports in pre-config are prefixed with `DEVICE_`, and are used to toggle
# features or identify installations in .zshrc or other scripts which are part
# of dotfiles.git.

device_preconfig() {
  source ~/.device_pre
}

# The post-config file is intended to run commands that are so specialized to
# the relevant device that it wouldn't make sense to include as a toggleable
# feature in the main .zshrc.

device_postconfig() {
  source ~/.device_post
}
