Vim Syntax File for Cpptraj

This repository contains the files necessary for syntax highlighting of cpptraj input files. vim will look for *.in files as use this syntax on them accordingly -- this can be changed in ftdetect/cpptraj.vim.

Example

Installation

If you clone this into your ~/.vim folder, you should be golden.

This ~/.vim folder should look like this (at a minimum):

.
├── ftdetect
│   └── cpptraj.vim
└── syntax
    └── cpptraj.vim

2 directories, 2 files

Otherwise, you can use these commands, in an internet-connected Terminal:

$ cd ~/.vim
$ mkdir ftdetect
$ mkdir syntax
$ cd ftdetect
$ wget "https://raw.githubusercontent.com/emleddin/vim-cpptraj/main/ftdetect/cpptraj.vim"
$ cd ../syntax
$ wget "https://raw.githubusercontent.com/emleddin/vim-cpptraj/main/syntax/cpptraj.vim"

syntax

This is where the actual rules for matches and keywords are contained.

ftdetect

This is where the file type autodetection rules are contained.

Not Working? Check These First

If you have vim installed but don't see normally colors, even in shell scripts, you may have to enable syntax highlighting by creating a ~/.vimrc file that contains syntax on.

The ftdetect/cpptraj.vim file specifies that files with a *.in extension are should use the cpptraj syntax. If you typically name your cpptraj files with something like .traj, you can modify this behavior by editing your ftdetect/cpptraj.vim to:

au BufRead,BufNewFile *.traj set filetype=cpptraj

TODO:

• More conditional highlighting (after this keyword, expect this)
• Verify read, write, dataset, and change commands have what they should
• Check for unintended duplicates (outtraj and pairdist?)
