Common Lisp Scripting with Roswell

"Roswell Script" is implementation-independent Common Lisp scripting program which uses Roswell. Although Roswell itself is a unified interface to Common Lisp implementations, it also encourages writing scripts with it.

To start writing it, run ros init in your terminal:

$ ros init
Usage: ros init [template] name [options...]

.vimrc
" Map leader to comma
let maplocalleader=","

" Toggle this for vim-sexp to not go into insert mode after wrapping something
let g:sexp_insert_after_wrap = 0
" Toggle this to disable automatically creating closing brackets and quotes
let g:sexp_enable_insert_mode_mappings = 1

Prereqs

These are for the combined vim-sexp (https://github.com/guns/vim-sexp) and vim-sexp-mappings-for-regular-people (https://github.com/tpope/vim-sexp-mappings-for-regular-people) plugins. vim-sexp is neat on its own but Tim Pope makes common stuff much easier.

Note that some vim-sexp functionality depends on <LocalLeader> mappings. This is a different leader key than the global leader, and is the variable maplocalleader (instead of mapleader). To see if you have this set, use :echo maplocalleader; if it errors out you'll need to set it, otherwise it will echo the key. If you want to set your LocalLeader to <Space>, you'll need two commands in your .vimrc, since by default <Space> is bound to <Right> in normal mode:

nnoremap <Space> <Nop>
let maplocalleader=" "
