Doesn't work in CLI Emacs

[losingkeys]

I see this error when trying to use this tool in emacs -nw:

Flycheck error display error: (wrong-number-of-arguments (1 . 1) 0)

Version info:

• GNU Emacs 25.3.1
• Flycheck version: 32snapshot (package: 20180525.814)

Let me know if I can help debug! Works in graphical Emacs, and is very nice :)

Thanks for the report! Can you M-x toggle-debug-on-error and reproduce the issue? It should give a full stack trace.

Yep, for this file:

fn whatever() {

}

I get this error immediately upon opening it (and after M-x toggle-debug-on-error), probably because the cursor lands right on the error when the file is opened:

Ok I see what's going on. You are using stardiviner/flycheck-inline which is the flycheck-inline on MELPA. This repository is also called flycheck-inline, and isn't on MELPA. It will replace stardiviner/flycheck-inline on MELPA soon, since we've all agreed that they were very similar, and this was a confusing situation. Indeed it is ;)

I'm happy to report that this version of flycheck-inline seems to work fine with emacs -nw. The switch on MELPA should happen soon enough.

[losingkeys]

Sweet! Sorry for the confusing PR, then. Looks like I can just wait until yours is merged, and re-run my (use-package flycheck-inline) config. Thanks again!

[fmdkdd]

MELPA PR has been merged. :tada:

[losingkeys]

Updated, it works! (and there are colors, ooooo). Thanks again!
