In vim 8, if you had the following string:
package Some::Package::Name;
and you placed your cursor on the S in Some::Package::Name and did a cw it would replace the text Some with whatever you typed.
In vim 9, cw now changes from S to the e in Name.
That behavior is probably due to a change in
/usr/share/vim/vim90/syntax/perl.vim
Muscle memory is hard to change, and I would prefer if I could revert back to Vim8 behavior. I've looked at the syntax file above and I am at a complete loss on how to change it.
Does anyone know how I can override this change in my vimrc?
My .vimrc remained unchanged between vim8 and vim9. With the following perl relevant sections:
au BufRead,BufNewFile *.pm set filetype=perl
au BufRead,BufNewFile *.t set filetype=perl
let g:ale_perl_perl_executable = '/opt/perl/bin/perl'
let g:ale_perl_perl_options = '-c -Mwarnings -Ilib -I/opt/perl/lib'
let b:ale_linters = { 'perl': [ 'perl' ] }
let g:ale_sign_column_always = 1
No, the built-in syntax script has nothing to do with this.
It's the built-in filetype plugin:
$VIMRUNTIME/ftplugin/perl.vim
that adds : to :help 'iskeyword', which is the option that tells Vim, among other things, where the next "word" start:
setlocal iskeyword+=:
In short, it tells Vim that : is part of the current word so cw skips it because it is not considered a separator anymore.
That setting was apparently added 9 years ago.
If you don't want it, you can create this file:
~/.vim/after/ftplugin/perl.vim
with this content:
setlocal iskeyword-=:
which is sourced after the built-in filetype plugin and thus overrides whatever option you set in it.
