Vim extensions for programming in NASL.

Installation can be done through Vundle or your favourite vim plugin manager.

Alternatively, for a bare-bones or custom install, just clone this repo and copy these folders (indent, syntax, syntax_checkers) into ~/.vim, then proceed with the instructions below.

Syntax Highlighting

Add the following to your .vimrc:

let nasl_space_errors = 1
autocmd BufNewFile,BufRead *.audit set syntax=xml
autocmd BufNewFile,BufRead *.nasl set filetype=nasl
autocmd BufNewFile,BufRead *.inc set filetype=nasl
autocmd BufNewFile,BufRead *.static set filetype=nasl
autocmd BufNewFile,BufRead *.inc set indentexpr=

To set the recommended formatting settings for NASL files, add this too:

autocmd FileType nasl setlocal shiftwidth=2 tabstop=2 expandtab softtabstop=2 colorcolumn=120

Syntastic

Currently, Syntastic support is provided by nasl -XLW (from the nessus package) or nasl-parse parse (from the nasl gem). Ensure that one of these is in your path to enable the syntax checker.

If you want to use both syntax checkers, you might want to add something like this to your .vimrc:

let g:syntastic_nasl_checkers = ['nasl_parse', 'nasl']

This will first run your file through nasl-parse and then, if no errors were found, run it through nasl.

Tagbar

Instructions here: https://github.com/majutsushi/tagbar/wiki#nasl.

Tagbar integration is very crude so far. The simple, regex method has many limitations, so a true parser method would be a huge improvement.
