Compatibility issue

[cflavio]

Hi! I am using mini-modeline (it is awesome). But, when I use it with mode-line-stats, I get this error (and I can't see it in the modeline):

mini-modeline: (error Invalid format operation %%$)

Emacs 25.2.2 here, I am using the last version on MELPA (pkg-info-package-version says 20200306.1000). Thank you!

Thank you, can you try with toggle error on and see if there's any error pop up?
Also the content of *Message* would help too.

And if possible, the minimal config that can produce the issue.

Hi! This is a minimal config that seems to replicate the issue:

(package-initialize)
(setq debug-on-error t)
(require 'mini-modeline)
(mini-modeline-mode t)

Thanks!

Can you upgrade to latest version and try again?
Show me the debug log too. Thanks.

[cflavio]

Thanks, it works! Now there aren't errors in the log. Anyway, mode-line-stats is not visible with mini-modeline (it is visible only in the buffer's modeline). Thank you very much!

[kiennq]

@cflavio I stopped trimming mode line, can you check if your mini-modeline-r-format or mini-modeline-l-format is set to contain mode-line-stats item?

[cflavio]

It works, thank you!
