vim-nonmem

Vim syntax and indent settings for NONMEM.

Installation

Use your favourite plugin manager. E.g., with vim-plug place this in your .vimrc:

Plug 'timwaterhouse/vim-nonmem'

… then run the following in Vim:

:source %
:PlugInstall

Filetype

I've purposely avoided adding any kind of filetype detection, due to the myriad conventions for naming NONMEM files. So you'll probably want to add something like the following in $HOME/.vim/filetype.vim (or elsewhere, see :help new-filetype) to appropriately set the filetype to nonmem:

if exists("did_load_filetypes")
  finish
endif
augroup filetypedetect
  au! BufNewFile,BufRead *.mod,*.lst setfiletype nonmem
augroup END
