Basic syntax highlighting for the ROOT Data Analysis Framework http://root.cern.ch/

Initially inspired by Theo Christoudias' plugin: cern_root.vim.

In contrast to cern_root.vim, this plugin is structured to work with common Vim plugin managers. It attempts to be semantically correct, which also allows seamless integration with both the PyROOT, as well as the original C++ implementation.

There are several methods for activating this plugin's syntax highlighting:

However, the methods that hold the most power, are those that are set using an equality; it is easier to chain the syntax. Therefore regardless of whether you are using the C++ implementation or PyROOT, the following will include the syntax:

So long as Vim had detected the use of c, cpp or python before, which it almost certainly would if you have the following in your vimrc.

filetype on
syntax enable

Although setting the filetype is more semantically correct, there can be some issues with plugins that use the &filetype variable to add functionality. If this occurs, then please inject the highlighting by setting the &syntax variable, as described above.

Reïterating the safest method is to use:

:se syn+=.root

Install this plugin by your preferred method. A few examples are given below.

You can install this using your favourite Vim package manager. If you are not using a package manager, you may find it helpful.

There are many different package managers, and it is assumed you know how to install the one of your choice and how to use them.

(Author's suggestion)

Place this in your .vimrc:

Plug 'parnmatt/vim-root'

Then run the following in Vim:

:source $MYVIMRC
:PlugInstall

Place this in your .vimrc:

Plugin 'parnmatt/vim-root'

Then run the following in Vim:

:source $MYVIMRC
:PluginInstall

For Vundle version < 0.10.2, replace Plugin with Bundle above.

Place this in your .vimrc:

NeoBundle 'parnmatt/vim-root'

Then run the following in Vim:

:source $MYVIMRC
:NeoBundleInstall

Run the following in a terminal:

$ git clone https://github.com/parnmatt/vim-root ${VIMRUNTIME:-$HOME/.vim}/bundle/vim-root

1. Clone this repository

    $ git clone https://github.com/parnmatt/vim-root
   

2. Place syntax file in Vim runtime path $VIMRUNTIME/syntax/root.vim

    $ mkdir -p ${VIMRUNTIME:-$HOME/.vim}/syntax/
    $ mv vim-root/syntax/root.vim ${VIMRUNTIME:-$HOME/.vim}/syntax/
   

3. Remove repository

    $ rm -rf vim-root
   

The above presumes you do not wish to keep the repository. If you do, It is suggested to either hard- or soft-link the files, rather than move them and delete the repository. This gives the added advantage of updating the file when new commits are pulled.
