One letter snippets do not expand using TAB

[brabalan]

Description

I have the auto-completion layer enabled, and one letter snippets do not expand using TAB, they only expand using M-/.

Snippets with two or more characters work correctly, as they are proposed in the company popup and they can then be expanded.

I have reproduced this using latex and emacs-lisp modes.

Reproduction guide

• Start Emacs
• Open a latex file
• type '-' followed by TAB

Observed behaviour:
Nothing happens, or the - gets indented

Expected behaviour:
The snippet bound to - (namely \item) would expand

Check if setting (setq company-minimum-prefix-length 1) helps.

It does not in this particular case because - does not start a company completion.

I guess that I want to decouple yasnippet from company …

For me one letter snippet does not start the completion menu, but the one letter snippet is expanded when I hit TAB.

Actually the variable auto-completion-tab-key-behavior 'complete does not change this behavior.

I looked into the auto-completion documentation, and it says M-/ exand a snippet. So I don't actually know why TAB expands snippets on my setup. Here yas-minor-mode binds TAB to yas-expand. I looked into my config and I haven't set that.

[brabalan]

Could you say what F1 k TAB returns for you? Here it's ident-for-tab.

[dl3br]

as I said, it is yas-expand on my setup. I haven't set that up. I assume you have yas-minor-mode on.

[brabalan]

yas-minor is on, yes. Looking at the code, I see this:

spacemacs/layers/auto-completion/packages.el

Line 214 in f49792e

;; disable yas minor mode map

which says that yas minor mode map is disabled and that hippie-expand is used instead. And a few lines above hippie-exp is set up with only the M-/ keybinding.

I'm confused.
