Warning and Message when opening a ruby file

[gguimaraesbr]

It happens everytime I open a ruby file:

Warning:
Error (use-package): enh-ruby-mode :config: Symbol's function definition is void: sp-with-modes

Message:
Suspicious state from syntax checker ruby: Checker ruby returned non-zero exit code 1, but no errors from output: ruby: no Ruby script found in input (LoadError) Checker definition probably flawed.

Any idea?

[bmag]

The warning probably means that a hook in enh-ruby-mode-hook assumes that smartparens is loaded when smartparens isn't loaded, or maybe the function sp-with-mdoes was removed upstream.
It will be easier to help if we know what version of spacemacs you are using. Please paste the output of SPC h d s.

The other message has to do with Flycheck encountering some errors. I don't know Ruby, but Flycheck (the package that provides syntax checking) has some commands for detecting errors. Try hitting SPC e v (bound to flycheck-verify-setup), maybe its output will be useful.

I can replicate the sp-with-modes ruby issue, here's the output of SPC h d s:

Hitting SPC e v gives the following output:

Same issue here opening ruby files via terminal emacs:

Error (use-package): enh-ruby-mode :config: Symbol's function definition is void: sp-with-modes

The Symbol's function definition is void: sp-with-modes error is caused because the Ruby layer tries to call this function before smartparens is loaded. I submitted a PR to fix it in develop - #4132. I don't use Ruby myself, does any of you run on develop sometimes and can test it?

About the other issue, Spacemacs uses Flycheck for the syntax checking functionality. Flycheck checks the syntax by running an external checker and checking its return code and output. IIRC Flycheck expects the checker to produce some error output when returning a non-zero return code. In @gguimaraesbr's case the checker didn't print any errors. If I understand the message correctly, the output of the checker was "no Ruby script found in input (LoadError)".

@gguimaraesbr according to your SPC e v, your checker is ruby. You can run SPC e h ruby to get some information about it. Here is part of the description for the ruby checker:

Please note that the output of different Ruby versions and
implementations varies wildly. This syntax checker supports
current versions of MRI and JRuby, but may break when used with
other implementations or future versions of these
implementations.

Please consider using ruby-rubocop' orruby-rubylint' instead.

So I guess you should install rubocop or rubylint.

I don't use Ruby myself, so I can't really help you much more. If you want to look further into this problem you should check out http://www.flycheck.org/resources.html and Flycheck questions in stackoverflow and https://emacs.stackexchange.com.

@wamaral I see you have rubocop. Does syntax checking work for you, or do you get the same "Suspicious state" message?

[wamaral]

@bmag syntax checking, as well as linting, works perfectly for me with rubocop.

I will check out the develop branch later today and report back.

[gguimaraesbr]

@bmag Installing rubocop and running on develop solved both issues. Thank you!

[wamaral]

I can confirm, no errors shown while using the develop branch. Thanks!
