I just pushed an update with a breaking change (0.3.0) where :show_first and :show_last pages are tagged :first and :last respectively – instead of just :page – when they’re separated from the normal pagination pages by an :ellipsis. So now they can be styled differently once the ellipsis starts appearing.

I just released an update to the package:

0.2.1

• Extracted the chunk generation; The part calculating which pages around the current one to show.
• Improved the performance especially when paginating a large number of pages

Small number: 1..100; Large number: 1..100_000; Number of pages to show: 5

Before:

Name                            ips        average  deviation         median         99th %
Small number of pages       23.33 K      0.0429 ms     ±7.68%      0.0420 ms      0.0520 ms
Large number of pages      0.0169 K       59.31 ms     ±9.67%       59.26 ms       73.17 ms

Comparison:
Small number of pages       23.33 K
Large number of pages      0.0169 K - 1383.32x slower +59.26 ms

After:

Name                            ips        average  deviation         median         99th %
Small number of pages      219.65 K        4.55 μs   ±290.11%        3.99 μs        5.99 μs
Large number of pages      210.09 K        4.76 μs   ±298.51%        3.99 μs        5.99 μs

Comparison:
Small number of pages      219.65 K
Large number of pages      210.09 K - 1.05x slower +0.21 μs

Additionally I’d like to note, that for all of you using liveview this library might be worth looking into. It will allow proper change tracking as all the markup is handled in the template and not in some function call the template engine has no way to look into.

I haven’t been in the need for implementing pagination in a while, but I’d still use this. The returned list should play well with liveviews change tracking
