Since it no longer seems to be actively maintained, and they are not working with 2.8+ versions, I took the liberty to combine them both into one single addon, and update them to run on Blender 2.82+.
I’m no coder, so I won’t pretend to know how this all works, the internals are mostly a mystery to me, but I can manage to do the trivial legwork. I sneaked in a few other adjustments here and there for modern conveniences like:
I tried to fix a few shortcomings and easy to catch issues but it was just low hanging fruit, there are still lots of corner cases that throw ugly Python error messages.
Add a few modern notifications to the status bar
It now registers by default working keyboard shortcuts, T for Trim and Shift + E for Extend
You can now trim and extend Poly type curves directly. Internally the algorithm still only knows how to work with Bezier curves, but I managed to make it do implicit conversion back and forth on the fly, restoring all you polys to their original type.
I updated for personal use but though you might like it as well.

One an half year… and only one 10 people liked it… como on man. this is awesome tool… a tiny yet most important tool for curve artists… specially for cad background artist.s
To celebrate the release of Blender 4.0 I decided to update my addons with a few minor improvements to mark the occasion. Bezier Curve Trim Extend 2.00 is now out
Bug fixes and improvements
Made a few minor simplifications to the code here and there for more reliable operation
Fixed a shortcoming of the previous algorithm that did not take into account curve radius, so trimming or extending curves would not always keep the correct curve radius
New Features
Bezier Curve Trim Extend can now work directly with Poly type curves. Internally the algorithm still only knows how to work with Bezier curves, but I managed to make it do implicit conversion back and forth on the fly. It will convert all Poly curves to bezier, complete the operations and restore them to their original state.
