dabbrev-expand ignores case sometimes

Hi,

I noticed that at times when I do a M-/ and try to complete a word that
already exists in the buffer (I assume, this is what I need to do if I need
to do what I did using C-p or C-n on vi), the word completion happens but
with weird casing. Sometime all caps etc. I wonder if there is some setting
I need to do when I get into this situation.

Regards,
Kashyap

Have you customized dabrrev? 

See (info "(emacs) Dabbrev Customization")

I have not customized dabrrev ... I believe I run into this accidentally
when I type in some control/alt combinations inadvertently.

Can you be more specific.  What is the guarantee that you haven't typed
M-l, M-u or M-c?

hmmm I am pretty sure its not M-I M-i or M-c . It's only M-/ and it simply
expands in an unexplainable manner.

RE: dabbrev-expand ignores case sometimes

[Ludwig, Mark]

Did you figure this out?

I believe you're running into behavior I have also seen.  Consider the following scenario.

In an otherwise empty buffer, enter the following three non-blank lines (blanks here for readability):

Test1String
TEST2STRING
Test

Run the following tests, each with the cursor at the end of the third line.  (It does not matter if there is a newline after the third line.)

Firstly, invoke M-/ and what you will get is Test2string.
Secondly, delete the third line and replace it with "TEST1" before invoking M-/ and what you will get is TEST1STRING.
Thirdly, delete the third line and replace it with "test2" before invoking M-/ and what you will get is test2string.

I don't what this case-matching behavior is called, but it catches me occasionally too....

Cheers,
Mark

If you want dabbrev to respect the case while completing, try setting
this: (setq dabbrev-case-replace nil)
