How can I get a list of the possible snippets programatically?

[khalidchawtany]

I want to integrate xptemplate into nvim-cmp. However, I cannot figure out how to get a list of possible snippets given an input.

For example: I have typed "i" without double quotes. How can I get all snippets that start with i?

I know about the <c->. However, I want to get the list calling a function.

Thanks

I'm unsure if the function call way meets your needs: the call will return some characters to emulate user input to trigger a popup menu.

These two functions have to be called in insert mode, and the return value has to be consumed as if they are keystrokes, with <C-r>=:

fun! ListSnippetsStartingWithPrefix() "{{{
    return XPTemplateStart(0, {"forcePum": 1})
endfunction "}}}

fun! ListAll() "{{{
    return XPTemplateStart(0, {"forcePum": 1, "popupOnly": 1})
endfunction "}}}

# i<C-r>=ListAll()<CR>

# i<C-r>=ListSnippetsStartingWithPrefix()<CR>
