semantic layer plus auto-completion layer: "Nothing to complete" errors after spaces in elisp

braham-snyder commented 7 years ago

Description

Relatively benign but very frequent error with semantic and auto-completion.

Reproduction guide

Fresh Spacemacs installation, master or develop branch
Install the semantic and auto-completion layers
Open a buffer in emacs-lisp-mode
Insert (a literal space) and wait a second or two

Observed behaviour:

Error, with *Messages*:

Company: An error occurred in auto-begin
Nothing to complete

Expected behaviour:

No error thrown.

Biggest issue is probably just that, unhandled, it makes toggle-debug-on-error quite unwieldy for other uses.

Possibly but not necessarily related: https://github.com/company-mode/company-mode/issues/614 https://github.com/abo-abo/lispy/issues/313

Can you replicate this with stock Emacs, company, and sematic?

Can you replicate this with stock Emacs, company, and sematic?

I cannot. No error with:

spacemacs/restart-stock-emacs-with-packages company,semantic
M-x company-mode
M-x semantic-mode
Insert

Are you unable to replicate it with Spacemacs?

CeleritasCelery commented 7 years ago

No, I can't reproduce your error following the steps you outlined above. Perhaps reinstall the packages?

braham-snyder commented 7 years ago

this is what I meant by "fresh installation" (fish script -- incidentally, I just tried reopening with zsh as $SHELL just to see, but same deal):

function reinstall_and_open_fresh_spcm
  trash ~/fresh-spcm
  mkdir ~/fresh-spcm
  git clone https://github.com/syl20bnr/spacemacs.git ~/fresh-spcm/.emacs.d
  cd ~/fresh-spcm/.emacs.d
  git checkout develop
  env HOME=$HOME/fresh-spcm/ emacs
end
