Expanding Snippets in evil-insert-mode

Question

I just moved to spacemacs from vim and am a complete newbie with emacs.

I cannot figure out how to expand yasnippets while in evil-insert-mode. I know yasnippet is available because I can choose from the available snippets using Spc i s. However I'd like to be able to <Tab> expand them. What am I missing?

Have you tried [company-mode](https://github.com/company-mode/company-mode)? I think it is very handy when dealing with auto completion---it has many different backends, and yasnippet is one of them. — xuhdev, Apr 06 '16 at 20:15
yeah, spacemacs comes bundled with auto-complete and company-mode. I'm not sure which one is in effect and not really sure how to find out. — owise1, Apr 06 '16 at 21:31
Use `describe-mode` (it's on ` m` in default Emacs), and search in 1st paragraph (where it says "Enabled minor modes: ..."). — npostavs, Apr 07 '16 at 14:46
thanks! it says company is enabled and yas. strangely I dont see company-mode's dropdown box with suggestions when I type and the yassnippets dont expand — owise1, Apr 07 '16 at 15:58

M-/ is the default binding to expand snippets not TAB. You can find this out with Spc ? then searching for yas

I have a stupid question - what does ```M-/``` mean? :) – aikeru Nov 14 '16 at 00:59

@aikeru not stupid. it means {option} + / – owise1 Nov 14 '16 at 17:18
so ```M``` is the ALT key on, say, a Linux or Windows machine, right? – aikeru Nov 14 '16 at 17:33

I think so yes. – owise1 Nov 14 '16 at 18:16
Should I remap `yas-expand` to `TAB` or not? There must be a good reason not to since that's the default, but I'm not understanding it. If I should remap, is there an option for this in Spacemacs? – Heisenberg Mar 25 '18 at 01:51

M-x yas-expand, you can C-h f yas-expand to check which hotkey is assigned.

company is an auto-completion framework which supports many backends. company-yasnippet could be its backend. If you use company-yasnippet, please check https://github.com/company-mode/company-mode/issues/492

I use yasnippets independently and assign global hotkey M-j to yas-expand

As I can see Spacemacs is not using the classic yas-expand but uses hippie expand which triggers yas-expand:

M-/ runs the command hippie-expand (found in global-map), which is an
interactive autoloaded compiled Lisp function in ‘hippie-exp.el’.

 is bound to M-/.

(hippie-expand ARG)

:around advice: ‘ad-Advice-hippie-expand’

Try to expand text before point, using multiple methods.
The expansion functions in ‘hippie-expand-try-functions-list’ are
tried in order, until a possible expansion is found.  Repeated
application of ‘hippie-expand’ inserts successively possible
expansions.
With a positive numeric argument, jumps directly to the ARG next
function in this list.  With a negative argument or just SPC u,
undoes the expansion.
