The `check` option performs two tasks through the configuration processing functions available at `src/configuration.sh`
|
|
|
|
1. Traversing the configuration directory to assemble a file list containing full paths for both the `base` and `bkp` directories
|
|
2. Comparing the installed packages with the `packages` file at the root of the configuration directory
|
|
|
|
The first task is currently accomplished by resorting to `find`. While this allows for cleaner code, it relies on a utility with variable behavior across operating systems. Given the simplicity of the query, a better option might be using a POSIX-compliant wildcard such as `.[!.]* ..?* *` to match the files directly (e.g., in a for loop). Another option that may provide both readability and portability is repeating the match, once for hidden file and once for non-hidden files.
|
|
|
|
The second task is accomplished by resorting to the package management functions available at `src/package.sh`. The `package_manager` function abstracts the actual package manager in the underlying system and provides an OS-independent way to query manually installed packages.
|
|
|
|
Through the parsed `packages` configuration file at the root of the configuration directory (`~/.config/tori/packages` by default), both package lists are sorted and deduplicated before they can be filtered by each other using `grep` inverted matching.
|
|
|
|
This allows obtaining both differences and displaying them to the user. If no conflict resolution strategy has been configured or passed through the command line interface, several options are displayed:
|
|
|
|
1. Install/uninstall all
|
|
2. Enter packages to install/uninstall
|
|
3. Add all to/remove all from configuration
|
|
4. Enter packages to add to/remove from configuration
|
|
5. Decide in editor
|
|
|
|
Not all of these options are implemented and some require significant more effort than others. The last option, in particular, requires defining and parsing a syntax that allows users to interface with the possible options.
