vimrc: don't fail with skip_defaults_vim setting if eval feature is m…
Browse files Browse the repository at this point in the history

If vim-tiny is present (lacking +eval feature, see `vim --version`),
then invoking vim fails with:

| Error detected while processing /usr/share/vim/vimrc:
| line   30:
| E319: Sorry, the command is not available in this version: let g:skip_defaults_vim=1

The /usr/share/vim/vimrc is a symlink to /etc/vim/vimrc:

| % ls -la /usr/share/vim/vimrc
| lrwxrwxrwx 1 root root 14 May 12 02:37 /usr/share/vim/vimrc -> /etc/vim/vimrc

Closes: #99

Just quickly tested with vim.tiny in my Debian/jessie docker:

root@c17833b790fb:/# cat /etc/debian_version 
8.11

root@c17833b790fb:/# dpkg -l | grep vim
ii  vim-common                2:7.4.488-7+deb8u4       amd64        Vi IMproved - Common files
ii  vim-tiny                  2:7.4.488-7+deb8u4       amd64        Vi IMproved - enhanced vi editor - compact version

root@c17833b790fb:/# vim.tiny /etc/vim/vimrc

(No vim-only binary was provided. Is there an update-alternative trick or so?)

I am not sure if we can expect our configuration to work with vim.tiny.

And here the output of my Debian/bullseye docker:

root@bf2ae5e25dda:/# dpkg -l |grep vim

Maybe we need to skip everything with vim-tiny?
