vim-bsv's Introduction

Vim plugin for Bluespec SystemVerilog (BSV)

Syntax highlighting
Autoindent
Autocomplete options:
1. From dictionary of words: ctrl-x ctrl-k
2. From imported files: ctrl-x ctrl-i
3. Above options are simply settings for vim's builtin 'complete' feature. Make it more useful with plugins like supertab or autocomplpop.
Move between matching keywords (%) with vim's built-in matchit plugin. Enable the plugin in vimrc:
```
if !exists('g:loaded_matchit')
    runtime! macros/matchit.vim
endif
```
Open imported file: In normal mode, press gf (goto file) with cursor over file name.

Rules for endwise

Features involving imported files use vim's path option to look for the files. There are several ways to do this:

Per project: set exrc secure, put a .vimrc in your project folder with set path=...
Per file: set modeline, put a comment at the beginning of your code // vim:path=...
Can export the per file setting globally with: autocmd BufWinEnter *.bsv if &l:path != '' | let &path = &l:path | endif
roll your own file format that can be read by both vim and your build script

Do :help path, :help exrc, :help modeline for more info.

I prefer the last option. In my top-level source folder, I have a file called "bsvpath". In vimrc:

function! BSVSetPath(srcdir)
    let pathfile = a:srcdir . '/bsvpath'
    if filereadable(pathfile)
        set path=
        for line in readfile(pathfile)
            if line =~# '^[^$/]'
                let line = simplify(a:srcdir . '/' . line)
            endif
            execute "set path+=" . line
        endfor
    endif
endfunction

autocmd FileType bsv call BSVSetPath(expand('<afile>:p:h'))
