Drawbacks

Snippets that make use of the entire functionality of this plugin have to be defined in Lua.

Requirements

Neovim >= 0.5 (extmarks)

Setup

Install using eg. vim-plug

Add mappings (Example from my config)

imap <silent><expr> <Tab> luasnip#expand_or_jumpable() ? '<Plug>luasnip-expand-or-jump' : '<Tab>' 
inoremap <silent> <S-Tab> <cmd>lua require'luasnip'.jump(-1)<Cr>

snoremap <silent> <Tab> <cmd>lua require('luasnip').jump(1)<Cr>
snoremap <silent> <S-Tab> <cmd>lua require('luasnip').jump(-1)<Cr>

imap <silent><expr> <C-E> luasnip#choice_active() ? '<Plug>luasnip-next-choice' : '<C-E>'
smap <silent><expr> <C-E> luasnip#choice_active() ? '<Plug>luasnip-next-choice' : '<C-E>'

Add Snippets: Snippets have to be added to the require'luasnip'.snippets-table. Examples contains more details, for actual snippets take a look at examples or my Snippets.

For Supertab-like functionality with compe, check out #1.

Config

history: If true, Snippets that were exited can still be jumped back into. As Snippets are not removed when their text is deleted, they have to be removed manually via LuasnipUnlinkCurrent.
updateevents: Choose which events trigger an update of the active nodes' dependents. Default is just 'InsertLeave', 'TextChanged,TextChangedI' would update on every change.
