nvim-if-lua-compat

An if_lua compatibility layer for Neovim (WIP, needs testing)

Goals

Maintain some amount of compatibility with the existing Vim interface for Lua (see also: neovim/neovim#12537).

Progress

Items annotated with an asterisk * are only partially supported.

• * vim.list() (actually a Lua table, luaeval() just makes a copy and transforms it into a Vim list...)
  • #l
  • l[k]
  • l()
  • table.insert(l, newitem)
  • table.insert(l, position, newitem)
  • table.remove(l, position)
  • l:add(item)
  • l:insert(item[, pos])
• * vim.dict() (actually a Lua table, luaeval() just makes a copy and transforms it into a Vim dict...)
  • * #d (Only works with Lua 5.2+ or LuaJIT built with 5.2 extensions)
  • d.key or d['key']
  • d()
• * vim.blob() (actually a Lua table)
  • * #b (Only works with Lua 5.2+ or LuaJIT built with 5.2 extensions)
  • b[k]
  • b:add(bytes)
• vim.funcref() (exists in Neovim core, but the implementation is different here)
  • * #f (Only works with Lua 5.2+ or LuaJIT built with 5.2 extensions)
  • f(...)
• vim.buffer()
  • b()
  • * #b (Only works with Lua 5.2+ or LuaJIT built with 5.2 extensions)
  • b[k]
  • b.name
  • b.fname
  • b.number
  • b:insert(newline[, pos])
  • b:next()
  • b:previous()
  • b:isvalid()
• vim.window()
  • w()
  • w.buffer
  • w.line (get and set)
  • w.col (get and set)
  • w.width (get and set)
  • w.height (get and set)
  • w:next()
  • w:previous()
  • w:isvalid()
• vim.type()
  • list
  • dict
  • blob
  • funcref
  • buffer
  • window
• vim.command() (alias to vim.api.nvim_command())
• * vim.eval() (alias to vim.api.nvim_eval(), doesn't actually return a vim.list/dict/blob)
• vim.line() (alias to vim.api.nvim_get_current_line())
• vim.beep()
• vim.open()
• vim.call() (in Neovim core)
• vim.fn() (in Neovim core)
