flymake-aspell backend getting disabled ... any suggestion how to get this working? about flycheck-aspell HOT 4 CLOSED

It's safe to say that I'm am unable to reproduce the issue at my end.

It's quite hard to debug such an issue without access to any backtrace, so maybe you could try getting one by enabling debug-on-error and manually running (flymake-aspell--check (lambda (&rest _))) in a buffer. Then just paste the whole debugger output here.

If doing that does not produce an error backtrace, debugging the issue might be more difficult. In that case, please tell me what version of Emacs you are using.

from flycheck-aspell.

This is on the current latest stable: 27.1. Executing:

(flymake-aspell--check (lambda (&rest _)))

in the scratch buffer gives the following, what for me doesn't immediately reveal anything obvious

Debugger entered--Lisp error: (wrong-type-argument stringp nil)

  flymake-aspell--check((closure (t) (&rest _)))

prior to this flyspell was working fine; the aspell version on my system:

[......:.emacs.d] $ aspell --version
@(#) International Ispell Version 3.1.20 (but really Aspell 0.60.8)

from flycheck-aspell.

Got it! (At least I am mostly certain)

You don't seem to have either ispell-dictionary or ispell-local-dictionary defined, which is what my package uses to determine what language to use.

Try setting one the dictionary variables (eg. to "en_US") and see if that fixes the problem. In any case, I will most likely make the package default to English if no dictionary is set. (In fact, flycheck-aspell already does that.)

setting ispell-dictionary indeed was the solution to make it work, thanks!

btw) Setting a default language to avoid this is issue would indeed be a good thing.
