I never want to use 'ignorecase' when searching for a tag. If the
cursor is over the symbol "cat" and I type Ctrl-], I want to find
the definition of "cat", not of "Cat" or "CAT". Similarly, I don't
want tag-name expansion to ignore case.
However, I do like to use 'smartcase' (which requires setting
'ignorecase') for searching with "/" or "?".
I've patched the copy of Vim I use at work to ignore the setting of
'ignorecase' for tag searches and to always search case-sensitively.
I would like not to have to keep doing this but I realize that
changing the default behavior of tag searches is a non-starter.
Consequently, I propose a new option, 'tagignorecase':
*'tagignorecase'* *'tic'*
'tagignorecase' 'tic' string (default "")
global
{not in Vi}
This option specifies how case is handled when searching
the tags file:
<empty> Follow the 'ignorecase' option
ignorecase Ignore case
noignorecase Do not ignore case
A patch is attached. The patch applies to too much--it includes
some runtime files that are managed by their owners--but I think it
covers everything that would need to be changed to include this
option.
I've been thinking more about the name. I chose 'tagignorecase'
because it is similar to almost all the other options that control
case sensitivity. However, those are all boolean options. I think
a better name might be 'tagcase'. It captures the meaning without
the implication that it is a boolean.
Since this is still at the early proposal stage, I just left the
original name in the proposal and in the patch.
Regards,
Gary
