Case of prefix when completing text

[villarragut]

Hi, @minad !

I'm using Corfu to complete text and I get the following behavior. I tried to search previous discussions and issues and I didn't manage to find anything related to it.

1. When I have a repeated word and the first occurrence starts with an uppercase letter, while the second occurrence starts with a lowercase letter, then lowercase prefixes turn uppercase. E.g.

Continuous functions are very nice. Let us study a specific continuous function. The cont

yields

Continuous functions are very nice. Let us study a specific continuous function. The Continuous

2. When I have a repeated word and the first occurrence starts with a lowercase letter, while the second occurrence starts with an uppercase letter, then lowercase prefixes remain lowercase and uppercase prefixes remain uppercase. E.g.

Let us study a specific continuous function. Continuous functions are very nice. The cont

yields

Let us study a specific continuous function. Continuous functions are very nice. The continuous

and

Let us study a specific continuous function. Continuous functions are very nice. The Cont

yields

Let us study a specific continuous function. Continuous functions are very nice. The Continuous

My question is: is this the expected behavior? Isn't it more natural to have the same behavior regardless of the order of the two preceding occurrences?

Thanks for your wonderful work!

What CAPFs are you using for this? Corfu does not provide the completions, it just allows selecting and applying them. What do you have set for completion-ignore-case?

Hello!

Thanks for the response.

The CAPF providing the results is cape-dabbrev. The value of completion-ignore-case is the default (nil). However, changing it didn't have any effect.

I checked the Issues section for the package Cape and this question was brought up there. @soficshift gave a fix which is working just fine for me.

Thank you for the pointers! I'll mark your comment as the answer, since it actually told me how to proceed.

Best wishes!
