Snippets are not reloaded after adding a new snippet about cmp_luasnip

[L3MON4D3]

Have you tried doing doautocmd User LuasnipSnippetsAdded after adding your snippets? It should happen automatically for snippets loaded via "luasnip.loaders.from_{vscode,snipmate}".load, but adding snippets to the table manually doesn't trigger the event.

Thanks for the suggestion, I tried that but then require("luasnip.session").latest_load_ft seems to be nil and causes this error:

Error detected while processing User Autocommands for "LuasnipSnippetsAdded":
E5108: Error executing lua ...ite/pack/packer/opt/cmp_luasnip/lua/cmp_luasnip/init.lua:29: table index is
nil

Ahh right, forgot about that. I added a function, "luasnip".refresh_notify(filetype) to trigger that autocmd correctly.

Thanks for your fast response! Unfortunately, I still get the same error even after upgrading Luasnip when running :doautocmd User LuasnipSnippetsAdded.

Are you calling doautocmd or the refresh_notify? :D

[smjonas]

Ohh at first I was using doautocmd but :lua require("luasnip").refresh_notify("lua") does nothing. Are you sure it is possible with that command since I don't think Lua will automagically reload my module with the snippet definitions :D? My snippets are in a plugins/luasnip.lua module so I tried :lua package.loadedp["plugins.loaded"] = nil, then reloading it with packer but this also didn't work.

[L3MON4D3]

Ohh, no, that we can't do. The refresh_notify only tells cmp_luasnip (or other plugins) that snippets were added.
You could register an autocommand that :luafiles plugins/luasnip.lua to reload your snippets, but that working also depends on what you do in there (won't work if you also load() snippets).
I recommend checking out this, it's a pretty nice setup that also has reload-capability.

Alright, thanks for these tips, I will check out the link! I guess, I was just used to it from UltiSnips, but there it's easier to reload snippets on file save since a special filetype is used.
