vimrc

Vim is cleany ported so the vimrc file goes in (IIRC): ~/config/settings/vim/.vimrc The exacpt paths for configuration files are listed in ":help starting". The Haiku version of vim will include the Haiku specific pathes there (other ports will not as the vim developers never upstreamed our patches).

A lot of things, not much of it being Haiku specific.

My settings file is here: https://github.com/pulkomandy/.dotfiles/blob/master/.vimrc

It enables mouse support, configures automatic indenting to match the Haiku coding guidelines, enables syntax highlighting, set the terminal tab title to the name of the file being edited, sets a better font (for gvim) and colorscheme, configure seqrch to be case sensitive, show results as you type, and highlight matches, shows lines numbers, allows folding of blocks by adding a fold gutter on the left, adds popups for code completion (if you have a ctags file), highlights the 100th (or 80th) column so you see when lines are too long, enable autowrite so :make automatically saves all files before compiling, sets special chars to make tabs and non-breakable space visible, and configure a few vim plugins, the most important being airline (which shows a fancy status line with the current git branch and various other useful informations).

I use ~/config/settings/vim/vimrc (without dot) here, and that is working.
