A way to prevent expand_auto() for some time while typing

[5721309]

Maybe there is a simple DIY solution like to assign an empty function to expand_auto, or to reconfigure luasnip on the fly (is it possible?).
But I feel you could provide us a function which receives boolean and accordingly enables or disables expand_auto. What do you think?

The bigger problem is that when you add autosnippets like if or while you believe that they shouldn't expand in some environments like @string or @comment. Using treesitter api seems hard for that - I haven't found any tutorial for that (have you?).

Use condition!
Dont have a link on hand, but it's in the DOC in the Snippet-section

Thank you, yes It seems I can use it. Here is the link to the DOC. We can pass conditions via opts parameter of s().

Write this in e.g. lua/snippets_common.lua

local M = {}

local expand_auto_allowed = true

vim.keymap.set({'i', 'n'}, '<A-a>', function() expand_auto_allowed = not expand_auto_allowed end)

local function condition_for_expand_auto()
	return expand_auto_allowed
end

M.expand_auto_condition = require("luasnip.extras.conditions").make_condition(condition_for_expand_auto)

return M

And then in your snippet files:

local eac = require('snippets_common').expand_auto_condition
-- ...
s('if ', fmt('if {} then\n\t{}\nend', { i(1), i(0) }), {condition = eac})

Nice 👍
You might want to take a look at extend_decorator, with that you don't have to always append the condition = eac-part

[5721309]

Ok, using extend_decorator looks easier, but I get an error when trying to apply it to s():

local s_eac = ls.extend_decorator.apply(s, {condition = eac})
-- ERROR : key found in more than one map: condition

Can you help me understand why that happens?

[5721309]

Nevermind, I think I understood. s() was registered in the way, that second argument to apply() is overwriting first parameter of s() and the next one overwrites the opts parameter.

local s_eac = ls.extend_decorator.apply(s, nil, {condition = eac})
-- ...
s_eac('if ', fmt('if {} then\n\t{}\nend', { i(1), i(0) }))

Yeeah exactly👍👍
