#repos_dir ⇒ Pathname (readonly)

Returns The directory that contains the source repo directories.

Returns:

  • (Pathname) —

    The directory that contains the source repo directories.

Returns:

  • (Pathname) —

    The path where the search index should be stored.

end

#updated_search_index ⇒ Hash{String => Hash{String => Array<String>}}

Returns the search data. If a saved search data exists, retrieves it from file and returns it. Else, creates the search data from scratch, saves it to file system, and returns it. Search data is grouped by source repos. For each source, it contains a hash where keys are words and values are the pod names containing corresponding word.

For each source, list of unique words are generated from the following spec information.

- version
- summary
- description
- authors

Returns:

  • (Hash{String => Hash{String => Array<String>}}) —

    The up to date search data.
