How to use keys ]]

[AckslD]

I'm trying to lazy load nvim-treesitter-textobjects on keys where one is ]]

use {
    'nvim-treesitter/nvim-treesitter-textobjects',
    module = 'nvim-treesitter-textobjects',
    keys = {
        {'o', 'af'},
        ...
        "]m",
        "]]",
        ...
}

but in packer_complied.lua I then get:

vim.cmd [[noremap <silent> ]] <cmd>lua require("packer.load")({'nvim-treesitter-textobjects'}, { keys = "[M", prefix = "" }, _G.packer_plugins)<cr>]]

How can I escape ]] properly?

Ah, this is a hopefully temporary limitation on our end. ]] is the sequence for "end raw string" in Lua, and we pass raw strings to vim.cmd to define keymaps. So, having that sequence inside the raw string terminates it prematurely and we get an error. Simply escaping it doesn't work either, because then we make a mapping to the literal string \]\] rather than what you wanted.

We could work around this by special-casing that keymap and adding a more complicated string constructor for the lazy-load keymap which breaks around the ]] to allow it to be used, but this seems like a significant amount of work for a niche case.

More ideally, when either we get a better mechanism for making keymaps in Lua (coming soon, hypothetically) or, potentially, as a side effect of #402 (since we won't need the string output of the argument to vim.cmd), this will go away.

Sorry for the probably unsatisfying answer!

Thanks for the clarification @wbthomason, I don't think this is of very high priority and sounds good that it can be fixed when refactoring 👍

Noting to myself: there might be a way to fix this, because I've learned about the "Nesting Quotes" section of http://lua-users.org/wiki/StringsTutorial. I'll still need to figure out exactly what to modify, but this gives us a mechanism for allowing maps like this.
