A REPL Client for Neovim

Requirements

• neovim >= 0.5
• popup.nvim
• plenary.nvim

Features

• REPL Environment for external interpreter (python, lua, node ...), still require extra code to clean prompt output from interpreter
• currently [ lua, vim, bash, javascript, python ] is working properly
• Support lua and vimscript embeded in neovim
• support prompt interactive input

Binding

Binding	Action
<Plug>(nvim-repl-current-line)	execute current line
<Plug>(nvim-repl-current-file)	execute current file (buffer)
<Plug>(nvim-repl-selection)	execute selection zone
<Plug>(nvim-repl-reset-interpreter)	close active interpreter
<Plug>(nvim-repl-win-open)	open REPL window in current tabpage
<Plug>(nvim-repl-win-close)	close REPL window
<Plug>(nvim-repl-win-toggle)	toggle REPL window
<Plug>(nvim-repl-buffer-clear)	clear buffer
<Plug>(nvim-repl-buffer-close)	close buffer (also close window)
<Plug>(nvim-repl-toggle-internal-external-mode)	toggle between internal and external mode (only for lua)
<Plug>(nvim-repl-show-prompt)	open interactive prompt input

Example Configuration

*HINT: Don't use noremap to map keys

nmap <leader>ax <Plug>(nvim-repl-current-line)
nmap <leader>af <Plug>(nvim-repl-current-file)
vmap <silent>aa <Plug>(nvim-repl-selection)

nmap <leader>ar <Plug>(nvim-repl-reset-interpreter)

nmap <leader>ac <Plug>(nvim-repl-win-close)
nmap <leader>ao <Plug>(nvim-repl-win-open)
nmap <leader>at <Plug>(nvim-repl-win-toggle)
nmap <leader>al <Plug>(nvim-repl-buffer-clear)
nmap <leader>as <Plug>(nvim-repl-buffer-close)

nmap <leader>am <Plug>(nvim-repl-toggle-internal-external-mode)
nmap <leader>ap <Plug>(nvim-repl-show-prompt)

Settings

-- optional, and every option is optional
-- if cmdpath isn't specified, using command base on filetype of the buffer
-- and javascript will map to node
require('nvimRelp').setup({
    lua = {
        cmdpath: 'full path to lua interpreter';
        cmd:     'using cmd to search executable file instead of filetype';
        -- only valid for lua to choose between neovim's embeded lua and external command line
        internal: boolean;
        -- if this option is nil, value pass to spawn will be { "-i" }
        args: { };
        env:  { "key=value" };
        stdoutSanitizer: function(out: string): [string, string];
        stderrSanitizer: function(err: string): [string, string];
    };
    vim = {};  -- this will not produce any effect

    -- javascript, python, ...
})

TODO

• spawn interpreter process with tty ?
