- battery: when state or icon change, update with _p9k_set_prompt. make sure icons can be sent with
  `typset -p` in zsh 5.1.
- ram: reduce precision to 2 digits. check if it makes sense for all segments that use the same
  function.
- to avoid resetting prompt too often (e.g., when battery remaining time changes by 1 minute), can
  do the following: send the current state from master to worker; worker sends new state if it's
  different but it only triggers prompt reset if it's sufficiently different. this requires
  disabling implicit reset on every eval in _p9k_worker_receive.
- implement fake gitstatus api on top of vcs_info (or plain git?) + worker and use it if there is no
  gitstatus.

  - if empty, keep looking
- ASDF_${upcase_name}_VERSION wins over everything
- deeper version overrides win
- .tool-versions wins over .ruby-version when in the same directory
- versions for different tools are looked up independently: if /foo/bar/.tool-versions doesn't
  override "ruby" it's as if it doesn't exist as far as ruby version is concerned.
- after upglob look $HOME (same file patterns)
- finally look at $ASDF_DEFAULT_TOOL_VERSIONS_FILENAME (single file; parse it like .tool-versions)
- ${ASDF_CONFIG_FILE:-~/.asdfrc} parsing:
    opt="$(
      grep -E "^\\s*legacy_version_file\\s*=\\s*" "$config_path" |
      head                                                     |
      awk -F '=' '{print $2}'                                  |
      sed -e 's/^[[:space:]]*//' -e 's/[[:space:]]*$//')"
    [[ $opt == yes ]]

Stat caches:
- ${ASDF_CONFIG_FILE:-~/.asdfrc} => legacy_version_file (yes or no)
- ${ASDF_DATA_DIR:-~/.asdf}/plugins => list of plugins
- ${ASDF_DATA_DIR:-~/.asdf}/plugins/ruby/bin => list of relevant scripts
  (list-legacy-filenames and parse-legacy-file)
- ${ASDF_DATA_DIR:-~/.asdf}/plugins/ruby/bin/list-legacy-filenames => list (or pattern made from it?)
- /foo/bar => { tool => version } (permanent cache via stat cache)
