Automating store_selection_keys

[tinny-blueleo]

Hi friends! I have mappings for generating snippets via lua functions, I'm trying to automate the process of wrapping lines in snippets like if statements or for loops if I have the line highlighted with line V mode. My store_selection_keys is set to <C-s> and in my function I try to automate the storing of the selection before expanding the snippet by trying to send <C-s> to the buffer like so:

vim.api.nvim_feedkeys(vim.api.nvim_replace_termcodes("<C-s>", true, false, true), vim.fn.mode(), true)

However when the snippet expands it doesn't expand the snippet around the line that I wanted. Anyone know if there is any API instead to store the selection or a better way to send the keys? Manually pressing Ctrl+s works before expanding the snippet.

Ouh, feedkeys is a bit difficult, because it will not immediately execute, I'd recommend reading :h feedkeys (the mode you're supposed to pass is not the vim-mode, but corresponds to certain feedkeys-behaviour, it's explained in the help). It's possible to work around that by queueing the lua-commands with the same feedkey-call, the downside here is that it gets pretty unreadable quickly.

We don't have an api for storing visual, we did not want to manually implement deleting the selection (here's the implementation).
(If you always delete entire lines, you could also manually call util.store_selection() and just delete the line yourself (nvim_buf_set_text))

This will work perfectly for my case, thanks for pointing me in the right direction L3MON4D3!

Hi L3MON4D3,

Sorry to bug you about this again. I'm trying to utilize store_selection but random lines are being stored in the selection and not necessarily what is highlighted before being in the snippet:

`if vim.api.nvim_get_mode().mode == "V" or vim.api.nvim_get_mode().mode == "v" then
require('luasnip.util.util').store_selection()
vim.cmd(":normal dd")
end

ls.snip_expand(snippet)`

I was trying to copy over the function directly from the implementation but it was throwing a syntax error around the <.

vim.cmd([[:lua require('luasnip.util.util').store_selection()<cr>gv"_s]]) and this wasn't working either for the store selection call.

Well, the <cr>gv"_s is part of a mapping, it does not work standalone in a cmd.

Maybe using nvim_feedkeys will do it.
