Thanks! I was actually able to find it with :
erpdev@erpdev:~/frappe-bench/apps/frappe/frappe$ grep -R "def sendmail"
I seem to have been complaining too loudly. My Sublime Text 3 was showing that exact reference every time I scrolled over the call to
sendmail, but I did not notice.
In my defence … as a n00B at Frappe coding … following Mehta and Doshi developer training videos 2015, it’s really anxiety inducing for them to show a documentation page that no longer exists and that Google can’t find even when one provides a dozen key words from the page.
I see that the method is annotated after all. What tool is expected to be used to generate docs from those annotations?
