i got rid of slot support-text in message-window, so that class does
not maintain a state.
- changed behaivour of split-line
(split-line (format nil "~2%")) ; => ("" "")
That is an emtpy line is returned as empty string and not skipped
Thanks to people from IRC and cl-ppcre maintainer for help!
- [breaking changes] changed 'hooks:*before-prepare-for-rendering-message*
with 'hooks:*before-rendering-message-text*.
this function was transforming "no" and even 0.0 (floating point number) to nil.
That behaivour was incorrect for numbers and probably not desiderable
for the string no (in fact poll with "No" option was not rendered
beacause of this fact).
Removed conversion for non- integer numbers and prevented conversion
from some kind of non empty string (like "nil" or "no") via a key
argument.
