# This script is meant to be sourced.

# See https://github.com/end-4/dots-hyprland/issues/2137
#
# Stage 1 todos:
# TODO: Properly handle hyprland config, ~/.config/hypr/hyprland.conf should be overwritten only when firstrun
# TODO: add --exp-files-path <path> Use <path> instead of the default yaml config
# TODO: add --exp-files-regen Force copy the default config to ${EXP_FILE_PATH} (auto do this when not existed)
# TODO: Implement versioning, i.e. when user-defined yaml config file has version number mismatch with the default one, produce error. If only minor version number is not the same, the error can be ommitted via --exp-file-no-strict .
# TODO: add --exp-files-no-strict Ignore error when minor version number is not the same
#
# Stage 2 todos:
# TODO: Implement bool key symlink (both read-write and read-only), when the value of `symlink` is true, then instead using `rsync` or `cp`, use `ln`.
# TODO: add --exp-file-reset-symlink Try to remove all symlink in .config and .local, which point to the local repo
# TODO: Update help and doc about `--exp-files` and the yaml config, including the possible values of mode.
#
# Stage 3 todos:
# TODO: Implement user-define yaml with merging (override) ability for user who only wants little customization and is satisfied with most of the defaults. User can use `./install-files.yaml` as custom config. When `./install-files.yaml` exists and have correct major version number, merge it together with `sdata/step/3.install-files.yaml` to generate a `cache/install-files.final.yaml` to determine how to copy files. About how to merge two yaml files, I know some software such as rime input method and docker supports a override yaml config, which we may reference from.
