How do I have multiple trigger for lua snippet?

[budimanjojo]

Hello! In vscode snippets, we can have multiple "prefix" to trigger the snippet. Is there a way to achieve this with lua snippet? context.trig is type of string so I don't think it's supported, but maybe there's a better workaround that I don't know of? Thanks!

Don't think there's a built-in solution, but I'm pretty sure you can try the following:

• Store the snippet you want as a return value in a function but leave the trigger key empty
• Create a table to store triggers you want for a specific snippet
• Iterate through the table and create a snippet.

For example, here is some skeleton code you can play around with:

local dummy_test = function(context, snippet, opts)
    opts = opts or {}
    if not context.trig then
        error("context doesn't include a `trig` key which is mandatory", 2)
    end 
    return s(context, snippet, opts)
end

local dummy_test_specs = {
    "dummy1", "dummy2", "dummy3" -- replace with other keywords you want to use
}
local dummy_snippet_body = {
    t("this is a dummy test snippet"),
    i(1), c(2, {t("more text"), i(1)})
}

local dummy_test_snippets = {}
for _, v in ipairs(dummy_test_specs) do
	table.insert(dummy_test_snippets, dummy_test({ trig = v }, dummy_snippet_body, { condition = in_text }))
end
vim.list_extend(M, dummy_test_snippets) -- this assumes M is the table of snippets; change if needed

And here is the code in action:

Thanks! I'll treat this as the most viable workaround for now.

Oh wow, great timing, I just worked on that xD
Check #774, it will support (amongst other things) multiple triggers.
