This vim plugin requires Vim 8 (released September 2016).
While editing a .prl file, run :RedPRL or <LocalLeader>l (l for load)
in the command (normal) mode to check the current buffer and display the output
in a separate buffer.
If there are any syntax errors, the cursor will jump to the first one.
Move this directory to ~/.vim/pack/foo/start/vim-redprl. (The names foo and
vim-redprl don't matter.)
If redprl is not in your PATH, add the following line to your .vimrc:
let g:redprl_path = '/path/to/redprl'
If you want to enable printing traces, add the following line to your .vimrc:
let g:redprl_trace = 1
If you want to recheck the current buffer with another key combination, add the
following line to your .vimrc, replacing <F5> as appropriate:
au FileType redprl nnoremap <F5> :RedPRL<CR>
