Description

Currently, ani-cli has several usability limitations that this PR addresses:

1. Search Results: Limited to a hardcoded 40 results.
2. Search Experience: Typos cause immediate script exit.
3. Filler/Range Management: No support for non-contiguous episode selection (e.g., skips).

Solutions Implemented:

1. Search Pagination: Introduced a "Next page" option in the interactive menu. If the API has more results, users can cycle through pages without re-searching.
2. Retry Logic: Wrapped the interactive search in a loop. If a query returns no results, the user is prompted: Search again? [Y/n]. Note: This includes a [ -t 0 ] check to ensure it never hangs in non-interactive/scripted environments.
3. Multi-Range Support: Refactored argument parsing and the play() function to allow multiple ranges. Users can now skip filler episodes using a command like ./ani-cli -e 1-5 -e 10-15 naruto.

Alternatives Considered

• Sequential processing: Kept logic POSIX-compliant rather than adding heavy dependencies like GNU Parallel.
• Simple limit increase: Pagination was chosen over just increasing the limit to 100 to keep the initial response fast and provide a better UX for very common search terms.

Additional context

• sh -n ani-cli passes (Appeased the linter).
• ani-cli -h updated with multi-range examples.
• Multi-range logic verified using debug player on large series like "Naruto Shippuden" and "One Piece".
• Non-interactive safety verified: Prompts are guarded by TTY checks to prevent hanging in headless scripts.

Additional Testcases

• Multi-Range Selection: ./ani-cli -e 1-2 -e 5-6 "Naruto" -> Successfully skipped eps 3-4.
• Empty Search: Searching for asdfghjkl -> Correctly show error and retry prompt (interactive) or exit (non-interactive).
• Pagination: Searching for One Piece -> Correctly showed "Next page" at index 41.
• Scripted Usage: echo "1" | ./ani-cli -e 1 "Naruto" -> Verified it selects result 1 and plays without prompting "Search again?".

• Config file: rejected. It's a command line app, use your *shrc to export env vars if you wish (but it's a nice implementation, just redundant)
• pagination and search looping: how does this affect non-interactive usage? I know for a fact we used to ask for an input in a loop (v2/v3 did that IIRC), and I don't remember why it changed, but it did have a reason
• more complex ranges: the only situation I can see this being useful is on a very slow internet connection where downloading is necessary and you can't delete the filler afterwards

All in all I'm split on the features, they aren't outright bad. There are a lot of changes (considering the size of the script), so we have to thread carefully as to not accidentally break existing workflows/functionality

Thanks for the detailed feedback! I’ve updated the code and force-pushed to address these points:

• Config File: Removed entirely. I agree that keeping the script stateless and relying on shell environment variables is cleaner for this project.
• Non-interactive Usage: I’ve added [ -t 0 ] checks to the search retry prompts. This ensures the script never hangs in scripted or headless environments. If it's not a real terminal, it exits on a failed search just like any other CLI tool.
• Complex Ranges: While specific, this is a standard feature in many media CLIs (like yt-dlp). It avoids multiple script runs when grabbing specific arcs of long-running series. I’ve kept the implementation strictly POSIX-compliant to avoid any overhead.

I've also updated the help information to reflect these changes. Let me know if everything looks good on your end now!

Unsalvagable imo, sorry
